CONTAGIOUS bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides subspecies mycoides SC, is one of the most important cattle diseases in many countries of sub-Saharan Africa. Traditionally, CBPP has been controlled by the live T1/44 vaccine, which has been used in Africa for over 60 years. Vaccination has been shown to be successful when coverage of the cattle population of a country or region is high and maintained over successive years. However, it is well known that the vaccine provides only short-term immunity, can cause severe adverse reactions and is rarely effective in the face of a severe outbreak. Furthermore, mathematical modelling has shown that even a mass vaccination campaign over a five-year period is unlikely to achieve eradication unless other strategies are also used (Mariner and Catley 2004). Previously, it was believed … ...
Contagious bovine pleuropneumonia (CBPP) is a severe infectious disease caused by Mycoplasma mycoides subsp. mycoides small colony type (M. mycoides SC) and is a vast problem in Africa. Current CBPP prevention is based on attenuated live strain vaccines, but these are limited by factors such as short-term immunity, cold-chain dependence and retained virulence. CBPP can be diagnosed using post-mortem examination, identification of the agent using culture and PCR based methods as well as serological diagnostic methods, but the latter are generally not sensitive enough and there is also demand for an inexpensive, pen side field test.The research presented in this thesis was focused on using recombinantly expressed surface proteins from M. mycoides SC to characterize humoral immune responses to CBPP. Thereby candidate proteins to be used in development of serological diagnostic methods and possibly subunit vaccines could be identified. As a first step, five putative variable surface proteins of M. ...

The demography of bovine infections caused by Mycobacterium avium subspecies paratuberculosis (MAP) in Ireland is poorly defined. The objective of this study was to describe the demographics of cattle positive to MAP on faecal culture, based on submissions to the Cork Regional Veterinary Laboratory (Cork RVL) from 1994 to 2006. The study focused on all available faecal samples from adult cattle with non-responsive chronic diarrhoea that were submitted by private veterinary practitioners to Cork RVL for MAP culture. For each MAP-positive by faecal culture animal, data were collated from Cork RVL and Cattle Movement Monitoring Scheme (CMMS) records. Johnes disease (JD) was confirmed in 110 animals from 86 herds by the Cork RVL between 1994 and 2006, with a rate of positive cases between 15% and 18% over last four years of the study. Two breeds (Holstein/Friesian or Limousin) made up 78% of submissions. Movements were assessed for the 57 study animals with available movement information, 90% died ...

Johnes disease (pronounced yo-knees) is a contagious, chronic and usually fatal infection that affects primarily the small intestine of ruminants. All ruminants are susceptible to Johnes disease. Johnes disease is caused by Mycobacterium avium subspecies paratuberculosis, a hardy bacteria related to the agents of leprosy and tuberculosis. The disease is worldwide in distribution.. A national study of US dairies, Dairy NAHMS 96, found that approximately 22 percent of US dairy farms have at least 10% of the herd infected with Johnes disease. The study determined that infected herds experience an average loss of $40 per cow in herds with a low Johnes disease clinical cull rate while herds with a high Johnes disease clinical cull rate lost on average of $227. This loss was due to reduced milk production, early culling, and poor conditioning at culling. The cost of Johnes disease in beef herds still need to be determined.. ...
Contagious Bovine Pleuropneumonia (CBPP) is a severe respiratory disease caused by Mycoplasma mycoides subsp. mycoides (Mmm) which is widespread in Africa. The main control option is a live vaccine, with low efficacy and a short duration of immunity. Development of an efficacious CBPP vaccine requires understanding immunogenicity of the antigens and protective immune responses. A series of experiments were undertaken to establish whether components of the Mmm, including whole cell lysate, membrane proteins and capsular polysaccharide can induce protection. Three separate experiments were conducted to evaluate the capacities to protect and detect possible correlations with immunological responses. The first experiment examined the efficacy of inactivated vaccine formulations: heat inactivated and formalin inactivated Mmm were compared with the live attenuated vaccine. Second experiment involved evaluation of a vaccine formulation generated from the Mmm membrane protein components. The third ...
In India, Holstein and its crosses are being used extensively in breeding programmes and all these breeding bulls are screened for autosomal recessive genes. Blood samples are collected in ethylenediaminetetraacetic acid (EDTA) coated tubes and DNA was isolated by using phenol-chloroform method. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) wereperformed by using bovine leukocyte adhesion deficiency (BLAD) specific primersand TaqI restriction enzyme for diagnosis of bovine leukocyte adhesion deficiency (BLAD) syndrome. The bull was found to be heterozygous for BLAD allele. The PCR product was sequenced by automated sequencer using the ABI big dye Ver 3.1 for detection of mutation at position 383 bp (A/G). Sequence analysis comparison was performed using the codon code aligner 4.0.4 software. The sequence of carrier animal confirmed polymorphism at 383 bp position. The sequence was also compared with sequence of normal Holstein as a control and the sequence available with
Disease Information. Johnes disease usually enters a herd when healthy but infected animals are introduced to the herd. Herds that are not infected should take precautions against introduction of Johnes disease. Such precautions include keeping a closed herd, or requiring replacement animals come from test negative herds. In 1998, the United States Animal Health Association approved the Voluntary Johnes Disease Herd Status Program for Cattle (VJDHSP). The VJDHSP provides testing guidelines for States to use to identify cattle herds as low risk for Johnes disease infection. With numerous tests over several years, herds progress to higher status levels. The higher the status level, the more likely a herd is not infected with Johnes disease. In April of 2002, USDA-Animal and Plant Health Inspection Services-Veterinary Service incorporated portions of this program into its national program standards: Uniform Program Standards for the Voluntary Bovine Johnes Disease Control Program (VBJDCP). ...
Johnes disease is an incurable illness of ruminants, caused by Mycobacterium avium subspecies paratuberculosis (Map). Once an animal is exposed to Map it can become infected or resist infection. Susceptible animals may develop Johnes disease with different severity levels or exhibit different levels of tolerance. Selection of animals that are resistant or tolerant to Johnes disease would reduce economic losses and reduce disease prevalence. Tolerance was measured by there relationship between fitness (Map fecal shedding) and infection intensity (Map tissue infection); infection was determined by the presence of Map in four tissues. We previously identified associations with a region on BTA 3 and Map tissue infection and on BTA15 with tolerance to Johnes disease using a whole-genome analysis. The objective of this study was to confirm the association on BTA3 and BTA15. On BTA15, 54 SNPs were used to interrogate a 193kb region and on BTA3, 42 SNPs were chosen for a 235kb region. Sixteen SNPs ...

Johnes disease or paratuberculosis is caused by the mycobactium species, Mycobacterium avium subspecies paratuberculosis. It affects the small and large intestine of ruminants. It causes thickening of the tissues which results in diarrhea and decreased absorption of nutrients. Mycobacterium avium subspecies paratuberculosis has been implicated by some research as the cause of Crohns disease in humans.
To more fully characterize the burden of Salmonella enterica in bovine peripheral lymph nodes (PLN), PLN (n=5,450) were collected from healthy cattle at slaughter in 12 commercial abattoirs that slaughtered feedlot-fattened (FF) cattle exclusively (n=7), cattle removed (or culled) from breeding herds (n=3), or both FF and cull cattle (n=2). Qualitative and quantitative methods were used to estimate prevalence and concentration of Salmonella in PLN. Isolates were subjected to a variety of phenotypic, serological, and molecular assays. Overall, Salmonella prevalence in PLN from FF and cull cattle was 7.1% and 1.8%. However, burden varied by season in that observed prevalence in PLN collected in cooler or warmer seasons was 2.4% and 8.2%, respectively. Prevalence in PLN from cull cattle in the southwest region of the US was 2.1% and 1.1% for cool and warm seasons, respectively; however, prevalence in FF PLN was far greater in that it was 6.5% and 31.1%, respectively. Salmonella was recovered from 289 (5.6%
The precise aetiology of enzootic haematuria in cattle remains unknown. The involvement of bracken fern (Pteridium aquilinium) appears certain because of the close association between bracken fern infested farms and enzootic haematuria. Several toxic principles have been identified but the main carcinogenic element remains to be conclusively demonstrated. More recently, bovine papilloma virus has been implicated in the aetiology of enzootic haematuria. Its possible interaction with bracken fern carcinogen is discussed.. ...
INTRODUCTION. In academic literature, it is debated whether ovarian follicular cysts (OFC) in dairy cows should be considered pathological or innocuous (Vanholder et al 2006). Up to the 1980s, classic clinical signs in cows with OFC as described in the literature were: short cycles, irregular estrus, nymphomania, masculinization, and relaxation of the pelvic ligaments (Kesler and Garverick 1982). However, dairy cows that currently develop OFC only present anestrus (Peter 2004, Vanholder et al 2006). Therefore, this ovarian condition is more often referred to as ovarian follicular cysts, and less as cystic ovarian disease.. According to Vanholder et al (2006), OFC can be defined as: follicles with a minimum diameter of 20 mm, present in one or both ovaries in the absence of a corpus luteum, and which interfere with cyclicity. Moreover, OFC are dynamic structures that may undergo regression and be replaced by new follicles, which later become OFC (Hamilton et al 1995).. Ovarian follicular cysts in ...
Johnes disease or paratuberculosis is caused by Mycobacterium avium subspecies paratuberculosis (MAP). The disease is characterized by chronic, debilitating enteric inflammation in ruminants and causes significant economic losses to livestock industries worldwide. Eradication efforts have been hampered by the fact that it is very difficult to detect the presence of MAP during early infection.. Progression of the disease is usually very slow so the subclinical early phase of the disease can last for years. During this time, however, MAP continues to be shed in the fecal matter of the animal and can therefore readily contaminate the environment. Nursing young stock is at very high risk to become infected, either through contaminated fecal matter on the teats or through MAP being shed in the milk.. During the early phases of the disease, production losses include decreased milk production, decreased fertility, and higher premature cull rates. The most prominent signs of Johnes Disease (incurable ...

Heck cattle are a hardy breed of domestic cattle. These cattle are the result of an attempt by the Heck brothers to breed back the extinct aurochs from modern aurochs-derived cattle in the 1920s and 1930s. Controversy revolves around methodology and success of the programme. There are considerable differences between Heck cattle and the aurochs in build, height, and body proportions. Furthermore, there are other cattle breeds which resemble their wild ancestors at least as much as Heck cattle. Heck cattle originated in Germany in the 1920s and 1930s in an attempt to breed back domestic cattle to their ancestral form: the aurochs (Bos primigenius primigenius). In the first years of the Weimar Republic, the brothers Heinz and Lutz Heck independently started their extensive breeding-back programmes. Their motivation behind that was to rescue the aurochs from oblivion because it was constantly confused with the wisent, the other large bovine of Holocene Europe. The Heck brothers believed that ...

Marshall and Ernst Windsor have run their herd of Hereford cows for almost 40 years now. Their operation is built around breeding and advancing genetics. Ernsts predilection is towards Herefords due to their sturdy build, adaptable nature, and their dependability during times of drought.. In 2001, the Ernsts moved their cattle ranch to Windsor. From then until 2012, the area of Windsor suffered from severe drought, and along with the rest of the industry, Ernsts herd suffered, with his cattle herd numbers dwindling significantly.. However, because of his Herefords, Ernst made it through a difficult time. And as the cattle industry undergoes even more changes, he expects to rely on the Herefords to help see him through once more.. Because of the drought, cattle numbers were dangerously low. And paired with a high beef demand, cattle prices hit an all-time high in 2015. As this perfect storm continues, the beef industry has slowly but surely begun to rebuild.. And the timing couldnt be better. ...

Cattle production follows a dynamic cycle that has often been analyzed, and cattle markets receive much scrutiny because of the potential for buyer market power. The relationship between the two has been little studied, however. This paper provides a simple conceptual framework to study how the cattle cycle and market concentration jointly affect the bargaining power of producers and packers yielding the following main results. Not surprisingly, a larger cattle stock reduces producers bargaining position, which results in a lower fed cattle price. More importantly, however, the cattle stocks negative effect on price is magnified by the market concentration in beef packing. Thus, the cycle itself is very importantly related to a posited cycle of bargaining power between cattle producers and beef packers. Secondly, the model also shows how beef packers may use the special feature of cattle as both consumption and capital goods to lower the cattle price by influencing cattle inventories. Crespi, John M.;
Cattle are large domesticated animals reared for beef or leather or kept to produce milk. The word cattle has no singular form, as the male bull and the female cow have markedly different temperaments. However, cattle are often referred to as cows, whether male or female. The offspring of cattle is a calf (plural calves). A castrated bull is called a bullock. During his sojourn in Haran, Jacob prospered while tending cattle for Laban. (Gen. 30:40) The female appears placid and contented and can be easily approached and milked, even by a child. The bull is considered dangerous and is typically penned up far away from any cows. Like many kinds of livestock their waste produces methane, an invisible and odorless gas, which liberals falsely maintain contributes to global warming. Cattle are susceptible to bovine spongiform encephalopathy, which when humans eat infected cows, they get CJD. CJD is a 100% fatal disease. All cows younger than 5 do not show symptoms of BSE. Cattle are slaughtered at 18 ...

Because of their native environment, the cattle are very hardy and can survive the Scottish winters, which are typically harsh, with snowfall and storms. Cows typically weigh 550 kilograms (1,210 lb) and bulls weigh 850 kilograms (1,870 lb). Calves are usually born smaller than is acceptable for the market, so crossbreeding with dairy cattle is needed for veal production.. The cattle are naturally polled and black in colour. They typically mature earlier than other native British breeds such as the Hereford or North Devon. However, in the middle of the 20th century a new strain of cattle called the Red Angus emerged. The United States does not accept Red Angus cattle into herd books, while the UK and Canada do. Except for their colour genes, there is no genetic difference between black and red Angus, but they are regarded as different breeds in the US. However, there have been claims that black angus are more sustainable to cold weather, though unconfirmed.. The cattle have a large muscle ...
The C (cattle) strain of Johnes Disease, which had previously been undetected in WA, has been discovered in an eight-year old home bred animal, indicating the disease has been present in that herd for at least eight years.. The S (sheep) strain of Johnes Disease has also been detected in several WA cattle herds.. The WA Department of Primary Industries and Regional Development has stated that as many as 480 herds could have been infected as a result of the detection in WA. While no details on the source of the detection have been revealed, the large number of potentially infected herds suggests the detection occurred in a large seedstock herd.. BJD can cause chronic wasting and diarrhoea in infected cattle and death in some instances. However the devastating costs of rules requiring the disease to be eradicated which were borne out in Queensland in late 2012 led most States and Territories to decide to live with BJD and allow producers to manage the disease at an individual herd level. ...

Johnes disease, caused by Mycobacterium avium subspecies paratuberculosis (MAP), manifests itself as a chronic diarrheal disease marked by wasting and eventual death . It occurs in wild and domesticated animals essentially worldwide, with the possible exception of Sweden and parts of Australia.. USDA officials view Johnes disease with some concern, as it is costly to manage and results in the early cull of infected animals and loss of production in dairy herds. Endemically infected herds worsen over time as the disease spreads. Johnes disease affects all ruminants, and cross-species infection has occurred. Johnes can be transmitted through feces, though milk, and via the womb. Young animals are especially susceptible. Although the cause of the disease was discovered in the early 20th century, many US beef and dairy producers are not familiar with its full implications. There are increasing concerns that the disease may pose a threat to public, as well as ruminant health.1. In contrast, ...

Two separate domestication events gave rise to humped zebu cattle in India and humpless taurine cattle in the Fertile Crescent of the Near and Middle East. Iran covers the Eastern side of the Fertile Crescent and exhibits a variety of native cattle breeds, however, only little is known about the admixture patterns of Iranian cattle and their contribution to the formation of modern cattle breeds. Genome-wide data (700 k chip) of eight Iranian cattle breeds (Sarabi N = 19, Kurdi N = 7, Taleshi N = 7, Mazandarani N = 10, Najdi N = 7, Pars N = 7, Kermani N = 9, and Sistani N = 9) were collected from across Iran. For a local assessment, taurine (Holstein and Jersey) and indicine (Brahman) outgroup samples were used. For the global perspective, 134 world-wide cattle breeds were included. Between breed variation amongst Iranian cattle explained 60 % (p | 0.001) of the total molecular variation and 82.88 % (p | 0.001) when outgroups were included. Several migration edges were observed within the Iranian cattle

Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel in production and research alike. Experiments were conducted in 2 studies to investigate aspects of nutrition and animal health in receiving cattle. Blood chemistry and immune components of sick and healthy cattle, along with feed intake, growth, and feed efficiency were evaluated for methods potentially useful in BRD diagnosis or offsetting performance losses. Intake, blood chemistry analysis, and immune proteins known as acute phase proteins provided patterns with possible complementarity for more accurate objective BRD diagnosis. Feed efficiency was improved by supplementing amino acids to exceed nutrient requirements. Utilizing these findings could provide incremental improvements in the current stalemate against BRD, improving both beef industry profitability and animal ...
* May placements up 12.0 pct vs year ago * June 1 feedlot cattle at 103.0 pct of year ago * Marketings in May up 9.0 pct vs year ago * Report mildly bearish for CME live cattle futures By Theopolis Waters CHICAGO, June 23 (Reuters) - U.S. ranchers during May drove12.0 percent more cattle into feedlots than a year earlier, themost for the month in a decade, the U.S. Department ofAgriculture reported on Friday, topping average predictions. Higher cattle prices paid by packers last month generatedmore profits for feedlot operators, allowing them to buy morecalves for fattening. Cattle that entered feedyards last month will be ready forprocessing beginning around October, analysts said. On Monday, Chicago Mercantile Exchange live cattle futures may see a mildly bearish response to Fridays reportbecause placements were not as high as some investors hadanticipated, said analysts. Market participants will mainly focus on next weeks cattleand wholesale beef prices, they said,
Cattle futures took the previous weeks bearish monthly Cattle on Feed report to start the week but then received another round of pressure from the crop-friendly quarterly Grain Stocks report.. Feeder Cattle futures took the brunt, along with cash prices, to a point, while stronger cash fed cattle prices provided underpinning.. Nationwide, steers and heifers sold from $2/cwt. lower to $2 higher, according to the Agricultural Marketing Service (AMS).. Demand remains good for yearling cattle, with light to moderate demand for fresh calves, say AMS analysts. Bawling and un-weaned calves continue to see discounts and are much less desirable to buyers as is typical for this time of year. Buyers are quite willing to pay premiums for cattle if producers invest time in them and provide a documented health program..

As of July 1, 2011 Canadian cattle herd was estimated at just below 13.9 million head, down 0.8% from the same date in 2010. Cattle inventories have been declining since their peak of 16.9 million in July of 2005. However, the rate of decline has slowed down since July 2010.. During the current period, the Canadian dairy herd grew 0.3%, while the total beef herd dropped 1.1%. Farmers reported a 2.1% decline in the total number of beef cows while replacement heifers were seen to increase by 6.7%. The total number of dairy cows was virtually unchanged from the same period a year ago, while replacement dairy heifers increased 0.8%.. With the exception of a 0.2 % growth in both Alberta and Saskatchewan, declines in cattle and calf inventories were pervasive. Cattle and calf farms in British Columbia reported a 0.9% decline in overall cattle holdings, while Manitoba and Ontario indicated that inventories declined by 3.3% and 1.9% respectively. Inventories declined by 2.2% in Quebec and were off 1.6% ...

The U.S. Department of Agriculture on Tuesday quoted choice boxed beef cutout at $241.70/cwt, up $2.57 from Tuesday and the highest in more than two years (all figures US$). Select cutout fell 25 cents, to $214.27, but was up from $200.58/cwt a week ago.. As a result, strong beef packer margins give them (processors) incentive to kill more cattle, which solves some of the problem of Tyson being shut down, Brugler said.. CME live cattle futures tumbled last week as news of the Tyson fire threatened to curb demand for fat cattle. But the market rallied on Monday after government data showed that last weeks U.S. cattle slaughter came in above expectations, despite the loss of the Kansas plant.. On Tuesday, CME October live cattle futures ended up 1.775 cents at 100 cents/lb., and October feeder cattle settled up 0.475 cent at 133.65 cents/lb..

Since 1994, Irish cattle have been exposed to greater risks of acquiring Mycobacterium avium subspecies paratuberculosis (MAP) infection as a consequence of the importation of over 70,000 animals from continental Europe. In recent years, there has been an increase in the number of reported clinical cases of paratuberculosis in Ireland. This study examines the prevalence of factors that promote the introduction and within-herd transmission of Mycobacterium avium subspecies paratuberculosis (MAP) on selected Irish dairy farms in the Cork region, and the association between these factors and the results of MAP screening tests on milk sock filter residue (MFR). A total of 59 dairy farms, selected using non-random methods but apparently free of endemic paratuberculosis, were enrolled into the study. A questionnaire was used to collect data about risk factors for MAP introduction and transmission. The MFR was assessed on six occasions over 24 months for the presence of MAP, using culture and ...

Mycobacterium avium subspecies paratuberculosis (MAP) causes Johnes disease (JD), a chronic, nontreatable enteritis of ruminants. The pathogen causes substantial losses to the dairy industry and might be associated with Crohns disease in humans. Eradication of MAP through programs that are solely based on test and cull is ineffective because current tests lack sufficient accuracy for reliable detection of infected cattle. Consequently, current MAP control programs focus on prevention of new infections through implementation of best management practices. The overall aim of this thesis was to evaluate the Alberta Johnes Disease Initiative (AJDI), a management-based MAP control program. Research in this thesis focussed on estimating MAP herd-prevalence, evaluating environmental samples as a diagnostic tool, identifying risk factors for MAP infection, and identifying factors that influenced management improvements. A total of 370 farms participated in the AJDI and were visited annually by their ...
Mycobacterium avium subspecies paratuberculosis (Map) is the aetiological agent of Johnes disease or paratuberculosis and is included within the Mycobacterium avium complex (MAC). Map strains are of two major types often referred to as Sheep or S-type and Cattle or C-type. With the advent of more discriminatory typing techniques it has been possible to further classify the S-type strains into two groups referred to as Type I and Type III. This study was undertaken to genotype a large panel of S-type small ruminant isolates from different hosts and geographical origins and to compare them with a large panel of well documented C-type isolates to assess the genetic diversity of these strain types. Methods used included Mycobacterial Interspersed Repetitive Units - Variable-Number Tandem Repeat analysis (MIRU-VNTR), analysis of Large Sequence Polymorphisms by PCR (LSP analysis), Single Nucleotide Polymorphism (SNP) analysis of gyr genes, Pulsed-Field Gel Electrophoresis (PFGE) and Restriction
A cluster of patients refers to the geographic proximity of unrelated patients with the same disease and suggests a common environmental cause for that disease. Clusters of patients with Crohns disease have been linked to the presence of an infectious microorganism in unpasteurized milk and cheese, untreated water supplied by wells or springs, animal manure used as fertilizer for family vegetable gardens, and bodies of water contaminated by agricultural runoff. Mycobacterium avium subspecies paratuberculosis (MAP) is the suspected cause of Crohns disease. MAP causes a disease in dairy cows and other animals that is similar to Crohns disease, called Johnes (Yo-knees) disease or paratuberculosis. Dairy cows with Johnes disease secrete MAP into their milk and excrete MAP into their feces. MAP is present in untreated water such as well water, in bodies of water contaminated by agricultural runoff, and in unpasteurized milk and cheese. The treatment of tap water to make it drinkable or
This thesis summarizes an investigation of Mycobacterium avium subspecies paratuberculosis (Map) as a pathogen within the cow-calf industry in Canada. The specific objectives of this project were to describe the distribution of this pathogen in this industry provincially, as well as at the individual farm level in wildlife species, and in the environment. Secondary objectives of this project were to identify on-farm management risk factors that are associated with this disease and to examine potential options for herd level diagnostic capabilities. Nationally, 0.8% (95%CI = 0.4-1.1%) of the cows in the cow-calf industry were seropositive for Map with 11.7% (95%CI=7.0-16.5%) of the herds sampled having a minimum of one positive test result or 4.5% (95%CI=1.4-7.5%) of the herds having a minimum of two positive test results. The true cow prevalence was estimated as 1.8% (95%CI= 0.4 - 3.1). No Map was detected in any of the non-ruminant wildlife species sampled on cow-calf operations suggesting that ...
Johnes disease is a chronic debilitating enteropathy of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). Current abattoir surveillance programs detect disease via examination of gross lesions and confirmation by histopathological and/or tissue culture, which is time-consuming and has relatively low sensitivity. This study aimed to investigate whether a high-throughput quantitative PCR (qPCR) test is a viable alternative for tissue testing. Intestine and mesenteric lymph nodes were sourced from sheep experimentally infected with MAP and the DNA extracted using a protocol developed for tissues, comprised enzymatic digestion of the tissue homogenate, chemical and mechanical lysis, and magnetic bead-based DNA purification. The extracted DNA was tested by adapting a previously validated qPCR for fecal samples, and the results were compared with culture and histopathology results of the corresponding tissues. The MAP tissue qPCR confirmed infection in the majority of sheep with
A total of six hundred ninety nine (699) blood samples were collected randomly from cattle population of different cattle farms belonging to rural unorganised sectors and organised cattle farms of seven different districts of West Bengal to study the seroprevalence of infectious bovine rhiniotracheitis (IBR) by Virus Neutralization Test (VNT). The seroprevalence of IBR among the cattle population of West Bengal was estimated to be 48.15% on district-wise study (highest seroprevalence rate of 85.29% in the cattle population of Nadia district and lowest rate of seroprevalence of 20.72% in the cattle population of Jalpaiguri district) and 42.32% on sampling area-wise study. Eighteen (18) serologically positive serum samples were selected as representative samples which were subjected to two fold end point titration. The end point titration of the seropositive samples collected from organised cattle farm of organised sector showed the IBR antibody titre to range from 1: 1 to 1: 8, while that of the samples

Abstract No. 104C-05. p. 61. Interpretive Summary: This work was performed to sequence the complete genome of an isolate of Mycobacterium avium subspecies paratuberculosis, the bacteria that causes Johnes Disease, that was obtained from a sheep. Previous studies have shown that there are differences between the bacteria recovered from infected cattle and sheep. The findings will be of use to other scientists who can compare the genome sequence with other available sequences. Technical Abstract: An isolate of Mycobacterium avium subspecies paratuberculosis (M. paratuberculosis) was cultured from the distal ileum of a sheep that had been diagnosed with Johnes Disease. Comparative genomic hybridization and short sequence repeat typing were used to characterize this isolate as typical of North American Johnes Disease sheep ...
The variation in sequence length within and among species might results from evolution and differentiation [10]. There are cases where variability might results from DNA duplication, DNA rearrangement, short tandem repeat (STR), insertions or deletion of sequences [11]. The length variation observed within and across species in this study might be due to differences in the genomic region where the sequences were obtained from and differences due to complete coding or partial coding. In CBPP and CCPP proteins, the sequences are partial coding sequences (CDS) from DNA and had sequence length that are less than six thousand base pair (,6000bp). This variability might initiate unique structures between individual members in conferring different biological activities. Many important biological processes such as cell signaling, transport of membrane-impermeable molecules, cell-cell communication, cell recognition and cell adhesion are mediated by membrane proteins [12]. Although there has been some ...
Cattle from Northern Portugal, many with pulmonary lesions typical of contagious bovine pleuropneumonia, were investigated for the presence of Mycoplasma mycoides subspecies mycoides small colony (MmmSC), which is the causative agent of CBPP, with several detection tests. sandwich ELISA that included a Culture enrichment stage, and 2 different PCR diagnostic systems were used to detect MmmSC in lung and mediastinal lymph node tissues from these animals. The comparison of typical CBPP pathology with the results of detection revealed that no single one of these methods provided a perfect match to the pathological data. Best performing tests were the PCR with laser induced fluorescence and PCR with pleuroTRAP kit (Chemicon, Australia), which are diagnostic systems based on amplification of genomic MmmSC DNA Followed by sensitive detection of the amplified products. These were followed by the broth-enriched sandwich ELISA, Which uses a monoclonal antibody specific to the M. mycoides cluster, to ...
COUNCIL DECISION of 20 February 1989 introducing a Community financial measure for the eradication of contagious bovine pleuropneumonia (CBPP) in Portugal (89/145/EEC) THE COUNCIL OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, and in particular Article 43 thereof, Having regard to the proposal from the Commission, Having regard to the opinion of the European Parliament (1), Whereas the presence of contagious bovine pleuropneumonia (CBPP) was established in Portugal in 1983 and a national campaign was immediately instituted for the eradication of this insidious and fatal disease; Whereas the continued presence of this disease militates against the free movement of bovine animals; Whereas the final eradication of this disease constitutes an essential prerequisite for the establishment - with regard to trade in cattle - of the internal market in bovine animals as well as for increasing the productivity of breeding and, consequently, improving ...
Paratuberculosis in cows is caused by Mycobacterium avium subsp. paratuberculosis. (MAP) Infected cows spread MAP in the environment. Recently Supershedder (SS) cows were recognized. These cows are spreading extremely high numbers of MAP in the environment. These MAP in the environment can be ingested by herd-mates causing positive fecal samples ... read more in these herd-mates. We hypothesized that these fecal positive cows become Pass through cows, ingesting the MAP and shedding MAP in the feces without becoming positive on tissue rather than Active passive-shedders, ingesting the MAP, shedding MAP in the feces and becoming positive on tissue. By using the Multilocus Short Sequence Repeats (MLSSR) method for 3 different loci (1, 2 and 8) on SS cows and cows that were fecal positive at the same time as the SS, in three different herds in the North East of the US, we aimed to evaluate if low shedders should be considered Pass through cows or Active passive-shedders and if Active ...

In the present study, a robust TaqMan real-time PCR amplifying the F57 and the ISMav2 sequences of Mycobacterium avium subsp. paratuberculosis from bovine fecal samples was developed and validated. The validation was based on the recommendations of International Organization for Standardization protocols for PCR and real-time PCR methods. For specificity testing, 205 bacterial strains were selected, including 105 M. avium subsp. paratuberculosis strains of bovine, ovine, and human origin and 100 non-M. avium subsp. paratuberculosis strains. Diagnostic quality assurance was obtained by use of an internal amplification control. By investigating six TaqMan reagents from different suppliers, the 100% detection probability was assessed to be 0.1 picogram M. avium subsp. paratuberculosis DNA per PCR. The amplification efficiency was 98.2% for the single-copy gene F57 and 97.8% for the three-copy insertion sequence ISMav2. The analytical method was not limited due to instrument specificity. The triplex real
Mycobacterium avium subspeciesparatuberculosis(MAP) belongs to theM avium complex (MAC). MAC occur widely in the environment and inhabit normal animal and human intestine. MAC do not usually cause disease unless the host is debilitated.MAP is a pathogen and causes chronic inflammation of the intestine in many animals, including primates.MAP is closely related genetically to other MAC but possesses additional DNA such as IS900, the hspX region, and the low %GC genetic element GS, which are associated with its pathogenic phenotype. Further genetic elements related to pathogenicity may be revealed by the whole genome sequencing ofMAP currently underway at the University of Minnesota. A recent review and extensive bibliography is available.1 MAP can colonise animals for years without causing disease. Chronic inflammation of the intestine (Johnes disease) may emerge after a long latent period, particularly when animals are stressed. Regional lymph nodes, liver, and lung are also involved. ...
Johnes disease is chronic inflammation of the intestine caused by Mycobacterium avium subspecies paratuberculosis. Infection and disease are mainly in domestic livestock but can affect many species including primates. Johnes is a new disease which emerged at the turn of the 19th and 20th centuries and principally involved Europe and North America. It has since spread to former low incidence regions to become a global problem. Crohns disease is a chronic inflammation of the intestine in humans which emerged in Europe and North America mid 20th century and increased to become a major healthcare problem. It has now spread to former low incidence regions. Infected animals shed Mycobacterium avium subspecies paratuberculosis in milk and into the environment. Human populations are widely exposed. Outcomes maybe influenced by microbial phenotype. Exposure to extracellular forms of these pathogens may confer some natural protection; exposure to intracellular forms which have passaged through milk ...
Jembrana disease virus (JDV) is an acute lentiviral infection of Bali cattle in Indonesia. Data generated during a series of cattle infection experiments was examined and significant differences were identified in the mean plasma viral load on the first and second days of the febrile response in cattle infected with JDVTAB/87 compared to those infected with JDVPUL/01. The peak and total viral loads ,= 106 genome copies/ml during the acute stage of the disease were significantly higher in JDVTAB/87 infected cattle. JDVPUL/01 infected cattle developed peak rectal temperatures earlier than the JDVTAB/87 cattle but there were no differences in the duration of the febrile responses observed for the 2 groups of animals. The plasma viremia was above 106 genome copies/ml for almost 3 days longer in JDVTAB/87 compared to JDVPUL/01 infected cattle. Atypical responses to infection occurred in approximately 15% of experimentally infected animals, characterized by reduced viral loads, lower or absent febrile ...
Chlamydia spp. are obligate intracellular gram-negative bacteria that cause a wide range of significant diseases in humans and animals worldwide, resulting in significant economic losses. Chlamydial infection in cattle has been reported in many countries including China. However, there has been no survey of chlamydial infection of dairy cattle in Guangzhou, southern China. The objective of the present investigation was to examine the chlamydial seroprevalence in dairy cattle in Guangzhou, subtropical southern China by using an indirect hemagglutination assay (IHA). The overall seroprevalence of chlamydial infection in dairy cattle was 7.25% (29/400). Greater than or equal to eight-yr-old dairy cattle had the highest seroprevalence (10.34%), followed by those that were ≥ 6 years old or | 7 years old dairy cattle (10.20%), although there were no statistically significant differences among different groups (P | 0.05). Dairy cattle with 5 pregnancies had the highest seroprevalence (10.81%). These results
Johnes disease is an untreatable, chronic, progressive bacterial intestinal disease of cattle caused by Mycobacterium avium subspecies paratuberculosis or MAP. A study conducted in 2009 by Good et al. estimated that the prevalence of Johnes disease in Ireland is 20% in dairy herds and 6% in beef herds. The disease is characterised by scour, reduced production - lower milk yields and feed conversion, weight loss leading to emaciation, soft swelling of the jaw or brisket (bottle jaw), and eventually death ...

Cattle are found all over the world, from as far north as Canada and Russia to the dry inland of Australia. The only continent they are not found on is Antarctica. Different types and breeds of cattle are suited to different environments. Bos indicus cattle such as the Brahman breed are suited to subtropical and tropical areas, whereas Bos taurus cattle such as Angus cattle are more suited to temperate or colder climates. Their large wide hooves are good in both wet areas and dry grassland. Their hairy coat grows much longer in the winter and has an extra fluffy layer to hold in warmth. They shed this extra layer in springtime in preparation for the hot summer ahead. Most cattle, except those of the Bos indicus subspecies do not have sweat glands in their skin, but their wet nose is a useful cooling system. They can also pant like a dog as well. Cattle can make a range of noises, from a gentle moo to a low growl in warning or to attract females, especially among bulls. When they are angry or ...

MGA® is a hormone material added to the ration of feedlot heifers. It improves rate of gain and feed utilization and suppresses estrus in feedlot heifers. Rate of gain was improved 10.3 percent and feed efficiency 6.5 percent in an average of 47 trials. MGA® may be combined with Rumensin or Bovatec in supplements or rations offered to heifers.. Bovatec® are feed additives that change rumen fermentation and improve the feed conversions of feedlot cattle by approximately 8 to 10 percent. Both are effective for steers and heifers fed growing or finishing rations. They give some protection against acidosis and founder when cattle are fed high-grain rations. Rumensin® has reduced feed intake with little change in rate of gain for cattle fed high-grain rations. Bovatec® has shown some improvement in daily gain for cattle fed high-energy rations.. Rumensin® has increased rate of gain and feed efficiency of cattle fed corn silage and other roughage rations. Cattle on pasture or those fed ...
All herds in the present study had generally overconditioned dry cows. Several studies have shown that overconditioned dry cows have a greater depression of feed intake ap and pp and deeper negative energy balance than cows with a lower body condition [1, 2]. In the present study 13% to 38% of the cows in all herds lost over 1.0 unit in BCS in early lactation, up to six weeks pp (Table 3). High BCS ap, as well as major losses in body condition have been associated with abomasal displacement, ketosis and other metabolism related diseases, decreased fertility and increased culling rates [2, 34, 35]. The high BCS ap and loss of BCS pp in all 5 herds most likely were major contributing factors to the herd problems with metabolic disorders.. Assessing the metabolic blood profiles may aid in investigating the herd problems by indicating the severity and timing of disturbed energy metabolism. Thus herds A and C had higher levels of NEFA ap than the other herds, for herd C mainly during the last week ...

MPI continues to build the picture of where the cattle disease Mycoplasma bovis is present and contain it to those farms.. The Ministry is working to assure farmers with properties in the vicinity of the affected Van Leeuwen Dairy Group farms that the control measures in place are sufficient to prevent the spread of the disease.. Ministry Director of Response Geoff Gwyn says the main way the disease can spread is through direct contact between cattle, such as nose to nose.. All the other potential factors such as on equipment, clothing and footwear, effluent and vehicles present a comparatively low risk.. We encourage farmers to pay attention to what are routine biosecurity measures such as on-farm hygiene, caution around stock movements and fencing stock back from neighbouring fence lines.. It is natural for people to be worried, especially those directly affected and living close by - but we dont want people to be unnecessarily concerned.. Mr Gwyn says MPI is holding a further community ...
Through the examination of 78 fecal sample of sheep and 52 fecal sample of cattle collected from different region in Ninevah governorate, the percentage of infection with schistosoma eggs in sheep and cattle were 7.69%, 19.23 respectively with significant differences between sheep and cattle, two types of eggs of schistosoma had been identified in sheep they were : S. bovis and S. indicum (first record) while in cattle S. bovis, S. indicum and S.intercalatum (first record) were diagnosed. Infection with S. bovis formed highest percentage in sheep and cattle 83.3%, 70% respectively. The results revealed significant differences between type of infection in sheep with significant difference between the type of infection in cattle, and the single infection formed highest percentage in sheep and cattle 83.33%, 70% respectively. The percentage of infection appeared with high rate in sheep and cattle with aged more than 3 years 9.8%, 40% respectively with significant difference between groups of age in cattle
Farms.com. A Saskatchewan farm organization is using virtual reality to transfer visitors at the Canadian Western Agribition in Regina, Sask. to a local cattle farm.. Anyone who visits the Saskatchewan Cattlemens Associations (SCA) booth can put on the headset and receive a 360-degree look at a cattle farm.. The experience is designed to attract Agribition visitors who may not be familiar with beef production.. This is an excellent idea because most of these kids here have never been to a farm, Larry Spratt, a producer from neat Melfort, Sask., told Global News yesterday.. In addition to being surrounded by cattle, users will hear a farmer explain the roles of other family members on the farm, the cattles lifecycle and animal husbandry practices. Theyll also get to see a feedlot and learn what the animals are fed.. Its one thing to talk to someone, but when theyre seeing the animals first-hand and reaching out to touch them, knowing full well the animals arent there, it becomes an ...

Abstract A cross-sectional serological survey was conducted on cattle pasturing in an area of the southern Italian Apennines to evaluate the seroprevalence to Neospora caninum, and to investigate the climatic, environmental, farm management, and individual animal factors that influence the distribution of this protozoan. Blood samples were collected from 864 pastured cattle raised on 81 farms. Serum samples were tested for antibodies to N. caninum using an ELISA assay (HerdCheck1, IDEXX). A geographical information system (GIS) for the study area was constructed using the following remote sensing (RS) and landscape feature data: autumn-winter, spring and summer normalized difference vegetation index (NDVI), land cover, elevation, slope, aspect, mean rainfall and minimum, mean, and maximum temperature in spring, summer, autumn and winter. Data on each of these features were then extracted for buffer zones consisting of the area included in a circle of 3 km diameter centered on the 81 ...
This report provides evidence of M. avium subsp. paratuberculosis infection in a wide range of nonruminant wildlife species in North America and confirms that the nonruminant infections reported in Scotland (3, 4) were not an isolated occurrence. In both of these studies M. avium subsp. paratuberculosis was isolated from tissue and feces from mammals and birds, and infections were detected on numerous premises. However, both the number of isolates and species infection prevalences were lower in our surveys than reported in Scotland (4, 11, 12).. It is now clear that M. avium subsp. paratuberculosis may infect animals in multiple taxonomic groups, but the pathogenic capacity of the organism for these species is still an open question. In Scotland, histological lesions were seen in rabbits (11, 12), foxes, weasels, a stoat, wood mouse, and crow (4). The absence of histological lesions in tissues from infected animals in our study may be related to the phase of infection in the culture-positive ...
The number one industry in Montana is agriculture and livestock makes up approximately two-thirds of the agriculture industry. Of the livestock portion, cattle make up the largest fraction. In fact, there are 2.6 million head of beef cattle in Montana. That means there are about three head of cattle for every human in the state of Montana. This makes Montana sixth in the United States for total number of beef cattle.. Montana also has 18,000 dairy cows, and on average each cow produces 16,833 pounds of milk per year. Dairy cows produce milk, which is very important, and milk can be made into other products like ice cream or cheese. Dairy farmers in this state produce enough milk to fill a football field 314 feet deep every year. Thats a lot of milk! Montana is also known as the seedstock capital of the world. Seedstock means registered cattle used for breeding. Other than meat and milk, cows provide us with other important by-products. Some edible examples include oleomargarine, gelatin and ...

Antibiotics have been employed by farmers and veterinarians for treatment of infectious cattle diseases for over 3 decades. The most common of these diseases in dairy cows is mastitis. Mastitis is defined by the National Mastitis Council (NMC) (49) as an inflammation of the mammary gland. It is the most prevalent and most costly disease .of dairy cattle. It is estimated that at least 50% of all cows are infected with some form of mastitis at any one time in one or more quarters; cows in the average herd contract clinical mastitis one and one-half times per yr (49) which results in economic loss. According to the NMC, the average estimated total mastitis cost per cow per year is $161.00. Penicillin alone or combined with other drugs has become the product of choice for treating many forms of infectious mastitis in the bovine. An estimated number of antibiotic treatments per case of mastitis is two (49). Therefore, using the NMC estimates and assuming 10 million cows in the United States, this places the
