Hellenic Veterinary Medical Society. Journal of the Hellenic Veterinary Medical Society.Journal part.Scientific article.2017 . Creators: COELHO, A. C., MOREIRA, F. A., CARDOSO, L..An outbreak of lameness occurred in a broiler breeder flock (30,000 birds into four houses) of a multi-age farm, with a total of two broiler breeder flocks (60,000 birds in total). The leg lesions began soon after facilities transfer between 22 and 24 weeks of age and persisted for the rest of the flocks life, until 64 weeks of age. Post-mortem examination at the farm revealed arthritis lesions and synovitis affecting the hock joint and the foot pads. Mycoplasma synoviae was detected in birds from the affected flock by serologic and molecular techniques. Treatments with fluoroquinolones in drinking water reduced the number of cases, but morbidity continued and affected the standard production rates..

Antibiotic growth promoters that have been historically employed to control pathogens and increase the rate of animal development for human consumption are currently banned in many countries. Probiotics have been proposed as an alternative to control pathogenic bacteria. Traditional culture methods typically used to monitor probiotic effects on pathogens possess significant limitations such as a lack in sensitivity to detect fastidious and non-culturable bacteria, and are both time consuming and costly. Here, we tested next generation pyrosequencing technology as a streamline and economical method to monitor the effects of a probiotic on microbial communities in juvenile poultry (Gallus gallus domesticus) after exposure to several microbiological challenges and litter conditions. Seven days and repeated again at 39 days following hatching, chicks were challenged with either Salmonella enterica serovar Enteritidis, Campylobacter jejuni, or no bacteria in the presence of, or without a probiotic (i.e.,

ADVANCES IN THE NUTRITION AND MANAGEMENT OF THE MALE AND FEMALE BROILER BREEDER R M GOUS SUMMARY Poultry nutritionists have based the feed requirements of broiler breeder hens on the principles designed for the feeding of commercial laying pullets because of the lack of information specific to these birds. The practice of restricting the feed intake of broiler breeders during both the rearing and the laying periods differs from the that of feeding commercial pullets, and was introduced as a necessity because of the rapid growth rate of broilers, but there is still debate about the reason for the benefit derived from this practice. The extent to which feed should be restricted; the optimum time of release from the restriction programme; the basis on which the amino acid requirements for maintenance and for egg output are calculated; and the optimum intake of energy .. at various stages of the produ.ction period, arc all as pects 0 f broiler breeder nutr itron that require further defi nitive ...

213). However, limiting on-farm use of antibiotics could significantly increase animal morbidity and mortality and compromise production efficiency and food security. Therefore, it is critical to replace antibiotics with alternatives that effectively mitigate pathogens on farm for sustainable and safe food production. Towards this end, by conducting multiple in vitro assays, we have identified two probiotics in our lab with strong antimicrobial activity against APEC. We hypothesized that probiotics can effectively prevent APEC infections in poultry, thus provide alternate strategy to control APEC and reduce the reliance on antibiotics. Furthermore, we have prepared probiotics microcapsules using chitosan-alginate microencapsulation technology; encapsulation prolongs the action of probiotics, thereby facilitate efficient delivery of the probiotics to chickens. Here, we propose to test the efficacy of identified probiotics to prevent APEC infections in poultry both in controlled laboratory ...

We analyzed 38 chicken embryos, processed the material collected following the histological routine, and then stained it with hematoxylin-eosin for the analysis of tissue structure and with Gomoris trichrome for the identification of conjunctive tissue and collagen fibers. We used the PAS histochemical technique for the analysis of neutral ...

Abstract: Background and Objective: Escherichia coli (E. coli) strains causing systemic disease in poultry (avian colibacillosis) are termed avian pathogenic E. coli (APEC). Colibacillosis is a disease of severe economic significance to all poultry producers worldwide and is characterized by a diverse array of lesions. Escherichia coli that cause infections usually possess one or more virulence properties that may help in establishment of the infection. The aim of this study was to investigate the virulence genes in E. coli isolated from broiler chickens. Methodology: A total number of 125 chicken samples from apparently healthy broiler chickens (25 and 15), diseased broiler chickens (25 and 15) and freshly dead ones (25 and 20) were collected in winter (from December, 2014 to February, 2015) and summer (from June, 2015 to August, 2016), respectively from Kafr El-sheikh Governorate. Results: In winter season, E. coli was recovered from 43 broiler chickens with an incidence of 57.3% and the ...

For this reason, its generally recommended that you dont start baby chicks and turkey poults together and that you house-grown turkeys and chickens separately.

Sun-dried blend of maize offal and blood (SDMBM) was analyzed and its effect on the per- formance of broiler chickens (Anak-2000 strain) evaluated. Fresh blood prevented from coagu- lation, mixed with maize offal, was sun-dried, ground, mixed again with blood and ground into a meal after drying again. The crude protein, fat, fibre, ash, ADF and gross energy contents of SDMBM were, 362.0, 45.5, 31.8, 69.3, 52.3 g/kg DM and 4.245 kcal/g, respectively. It was ade- quate in all essential amino acids for growing broiler chickens except methionine. Eighty 14- day-old commercial broiler chicks were ran- domly allocated to four dietary treatments (fed ad libitum; four replicates each) consisting the control diet (0 g SDMBM/kg diet), which con- tained fishmeal, groundnut cake and soybean meal, and three other diets (50, 100 and 150 g SDMBM/kg diet). In a feeding trial, the starter (14 to 35 d) and finisher (35 to 49 d) dietary treat- ments did not have significant impact (P | 0.05) on body weight gain,

Interpretive Summary: Corn is the main grain that provides energy to a baby turkey poults diet so that it can grow. However, at the present time corn is very expensive to use in animal diets. Therefore, alternative grain products are being investigated for their ability to provide energy to a growing poults diet. Rye is one such grain to be considered as a feed energy source for a baby poults diet. These experiments show that a rye-based diet is not a good feed ingredient because it causes damage to the baby poults intestine that result in poor growth by the poult. These experiments are important to poultry nutritionists because they show that rye is not a good source of energy for baby poults diets and that different grains need to be tested to see if they will help the growth of baby turkey poults. Technical Abstract: Rye contains high concentrations of non-starch polysaccharides (NSP), leading to reduced digestibility. Since poultry have little or no endogenous enzymes capable of ...

The extraintestinal pathogen, avian pathogenic E. coli (APEC), known to cause systemic infections in chickens, is responsible for large economic losses in the poultry industry. To identify genes, involved adhesion and colonization, a lung colonization model of infection was established in 5-week old specific-pathogen free (SPF) chickens, and Signature-tagged mutagenesis (STM) was applied to this model by generating and screening a total of 1,800 mutants of an APEC strain IMT5155 (O2:K1:H5; ST complex 95). This led to the identification of new genes of interest, including adhesins, genes involved in capsule and LPS formation, and genes of putative function. Among the many genes identified was one coding for a novel APEC fimbrial adhesin (Yqi) not described for its role in APEC pathogenesis. Its gene product was temporarily designated ExPEC Adhesin I (EA/I). Deletion of the ExPEC adhesin I gene resulted in reduced colonization ability by APEC strain IMT5155 both in vitro and in vivo. ...

Genetic selection for improved meat yields, digestive efficiency and growth rates have transformed the biology of broiler chickens. Modern birds undergo a 50-fold multiplication in body mass in just six weeks, from hatching to slaughter weight. However, this selection for rapid growth and improvements in broiler productivity is also widely thought to be associated with increased welfare problems as many birds suffer from leg, circulatory and respiratory diseases. To understand growth-related changes in musculoskeletal and organ morphology and respiratory skeletal development over the standard six-week rearing period, we present data from post-hatch cadaveric commercial broiler chickens aged 0, 2, 4 and 6 weeks. The heart, lungs and intestines decreased in size for hatch to slaughter weight when considered as a proportion of body mass. Proportional liver size increased in the two weeks after hatch but decreased between 2 and 6 weeks. Breast muscle mass on the other hand displayed strong positive

Looking ahead, Rennier expects the No Antibiotics Ever category will continue to grow rapidly and probably account for 18% to 22% of the US poultry market by the end of 2016. By 2017, however, growth might be limited to another 3 to 5 percentage points.. The US poultry industry is over the hump with antibiotic-free, Rennier explained. The 2015 figures show people are in the trial mode - preparing to do what theyve done in 2016 - and its going to take them another year or two to get their learnings under the belt before they start extrapolating that to their other complexes.. Even so, by 2021, Rennier projects more broiler feed will be made without antibiotics, but its difficult to make an accurate prediction until the new VFD rules are fully adopted. At the same time, broiler feed in the Full Spectrum category should fall as the industry weans itself from feed medications. The Reduced Use and Ionophores Only categories will see some fluctuations but probably nothing dramatic.. * Renniers ...

FPD is an inflammatory disorder with necrotic lesions on the plantar surface of the birds feet, which may be superficial or deep. Due to the inflammatory and other pathological characteristics of the lesions, poultry specialists have assumed the condition to be painful, negatively affecting bird welfare and performance (Rault and Matthews, 2014). In addition to these considerations, the impact of FPD on economic performance in the poultry industry is very important because it causes downgrades and condemnations of saleable chicken paws. In this sense, the US revenue of chicken paws was estimated at 270 million USD from export to Asian countries in 2018 (Cang, 2020). Therefore, harvesting unblemished paws has become a main concern to poultry companies all over the world.. The most critical risk factor for the development of FPD is the litter condition. The litter moisture and ammonia concentration from built-up feces can burn the dermis of the footpad, with an enhanced FPD resulting from the ...

A campaign to promote poultry consumption and the benefits of the poultry industry to Brazil is to continue after a successful start.

PETA is especially concerned about poultry packing plants, which have received less scrutiny than beef and pork processors though more than 90% of animals killed for food in this country are chickens. The standard method for slaughtering chickens -- at a rate of 11,000 birds an hour -- involves shackling them upside down from a conveyor belt that runs along the ceiling. Their heads are dunked in a shallow stun bath to anesthetize them. A revolving blade then slices their necks. Chicken processors defend their methods as humane, arguing that its a lot less traumatic than the old-fashioned farm-boy method of wringing the birds neck. But activists contend that many chickens are not properly stunned or sliced, and end up boiling to death in the scalding tank meant to loosen their feathers. Ive stood there on the kill floor and seen how they look at you. They try everything in their power to get away. They may not be able to read and write, but they know whats going on, said Virgil Butler, a ...

Recently, multiple spillover events between domesticated poultry and wild birds have been reported for several avian viruses. This phenomenon highlights the importance of the livestock-wildlife interface in the possible emergence of novel viruses. The aim of the current study was to investigate the potential spillover and epidemiological links of infectious bursal disease virus (IBDV) between wild birds and domestic poultry. To this end, twenty-eight cloacal swabs were collected from four species of free-living Egyptian wild birds (i.e. mallard duck, bean goose, white-fronted goose and black-billed magpie). Genetic and phylogenetic analysis of three positive isolates revealed that the IBDV/USC-1/2019 strain clustered with previously reported very virulent IBDV (vvIBDV) Egyptian isolates. Interestingly, two other wild bird-origin isolates (i.e. IBDV/USC-2/2019 and IBDV/USC-3/2019) grouped with a vaccine strain that is being used in commercial poultry. In conclusion, our results revealed the ...

Avian infectious laryngotracheitis (ILT) is a worldwide infectious disease that causes important economic losses in the poultry industry. Although it is known that ILT virus (ILTV) is present in Argentina, there is no information about the circulating strains. With the aim to characterize them, seven different genomic regions (thymidine kinase, glycoproteins D, G, B, C, and J, and infected cell polypeptide 4) were partially sequenced and compared between field samples. The gJ sequence resulted to be the most informative segment, it allowed the differentiation among field sample strains, and also, between wild and vaccine viruses. Specific changes in selected nucleotidic positions led to the definition of five distinct haplotypes. Tests for detection of clustering were run to test the null hypothesis that ILTV haplotypes were randomly distributed in time in Argentina and in space in the most densely populated poultry region of this country, Entre Rios. From this study, it was possible to identify a 46 km

Bicephalia is one of the scarcest malformations reported in birds and needs to be fully investigated in chick embryos. Among 1500 fertilised eggs used to examine the primordial germ cells in 2-day and 5.5-day chick embryos Gallus gallus domesticus, bicephalia was found and the condition of the heads, the heart and other parts of the body was fully described. Each twin had its own head; hearts were not completely separated from each other and the rest of the bodies were externally unique. This investigation urges others including poultry farms to share their data on a bigger scale. It may also encourage the monitoring of abnormalities randomly seen during early chick embryogenesis and consideration of environmental factors when poultry farms are faced with high percentages of unsuccessful hatching. The report can shed some light on developmental processes and may also help to clarify why bicephalia is not more common. ...

Chickens are bred all over the world and have significant economic value as one of the major agricultural animals. The growth rate of commercial broiler chickens is several times higher than its Red Jungle fowl (RJF) ancestor. To further improve the meat production of commercial chickens, it is quite important to decipher the genetic mechanism of chicken growth traits. In this study, we found that broiler chickens exhibited lower levels of E3 ubiquitin ligase muscle atrophy F-box (MAFbx or Atrogin-1) relative to its RJF ancestor. As a ubiquitin ligase, Atrogin-1 plays a crucial role in muscle development in which its up-regulation often indicates the activation of muscle atrophic pathways. Here, we showed that the Atrogin-1 expression variance partly affects chicken muscle growth rates among different breeds. Furthermore, we demonstrated that the reduced expression of Atrogin-1 in broiler chickens was ascribed to a single nucleotide polymorphism (SNP), which inhibited the binding of ...

An adult layer chicken was brought for necropsy examination with the history of sudden death. Upon opening the abdominal cavity, there was a shell-less egg in the abdominal cavity, the oviduct was highly congested and the mucosa of the anterior portion of oviduct was seen prolapsed through a tear in the oviductal wall. Microscopically, the mucosal epithelium revealed severe degenerative to necrotic changes with severe congestion. Based on the gross findings, the case was diagnosed as oviduct rupture with prolapse.

Both high and low pathogenic subtype A avian influenza remain ongoing threats to the commercial poultry industry globally. The emergence of a novel low pathogenic H7N9 lineage in China presents itself as a new concern to both human and animal health and may necessitate additional surveillance in commercial poultry operations in affected regions. Sampling data was simulated using a mechanistic model of H7N9 influenza transmission within commercial poultry barns together with a stochastic observation process. Parameters were estimated using maximum likelihood. We assessed the probability of detecting an outbreak at time of slaughter using both real-time polymerase chain reaction (rt-PCR) and a hemagglutinin inhibition assay (HI assay) before considering more intense sampling prior to slaughter. The day of virus introduction and R 0 were estimated jointly from weekly flock sampling data. For scenarios where R 0 was known, we estimated the day of virus introduction into a barn under different sampling

Resistance to antibiotics is on the rise partly due to inappropriate use by humans and partly due to the widespread use of these drugs in the livestock and poultry industry.. Like humans, birds and animals are easily susceptible to infections. Poultry farms are very prone to bacterial epidemics as the birds are held in cages in close captivity which brings them in extremely close contact with one another. They also share water and feed troughs which causes illnesses to spread rapidly. Sometimes, veterinarians recommend using antibiotics to prevent diseases when there is a very bad outbreak of bacterial infection, but many poultry owners use these antibiotics indiscriminately. Antibiotic use in the poultry industry has reached epic proportions because it is easier and inexpensive to administer drugs instead of keeping the birds healthy organically by keeping the environment of the farm clean and hygienic and giving the birds space and good nourishment to grow. In addition, even as awareness about ...

The food supply, including poultry products, may transmit antimicrobial drug-resistant Escherichia coli to humans. To assess this hypothesis, 931 geographically and temporally matched E. coli isolates from human volunteers (hospital inpatients and healthy vegetarians) and commercial poultry products (conventionally raised or raised without antimicrobial drugs) were tested by PCR for phylogenetic group (A, B1, B2, D) and 60 virulence genes associated with extraintestinal pathogenic E. coli. Isolates resistant to trimethoprim-sulfamethoxazole, quinolones, and extended-spectrum cephalosporins (n = 331) were compared with drug-susceptible isolates (n = 600) stratified by source. Phylogenetic and virulence markers of drug-susceptible human isolates differed considerably from those of human and poultry isolates. In contrast, drug-resistant human isolates were similar to poultry isolates, and drug-susceptible and drug-resistant poultry isolates were largely indistinguishable. Many drug-resistant human fecal E.

In Taiwan, avian influenza virus (AIV) subtypes H5N2, H6N1 and H7N3 have been identified in domestic poultry, and several strains of these subtypes have become endemic in poultry. To evaluate the potential of avian-to-human transmission due to occupational exposure, an exploratory analysis of AIV antibody status in poultry workers was conducted. We enrolled 670 poultry workers, including 335 live poultry vendors (LPVs), 335 poultry farmers (PFs), and 577 non-poultry workers (NPWs). Serum antibody titres against various subtypes of viruses were analysed and compared. The overall seropositivity rates in LPVs and PFs were 2·99% (10/335) and 1·79% (6/335), respectively, against H5N2; and 0·6% (2/335) and 1·19% (4/335), respectively, for H7N3 virus. Of NPWs, 0·35% (2/577) and 0·17% (1/577) were seropositive for H5N2 and H7N3, respectively. Geographical analysis revealed that poultry workers whose workplaces were near locations where H5N2 outbreaks in poultry have been reported face greater ...

This is probably the commonest cause of coccidiosis in chickens and occurs worldwide. It is seen in layers and in broilers, both alone and in association with other species of coccidia and is caused by Eimeria acervulina, which is moderately pathogenic. Morbidity is variable and mortality low or absent. Eimeria mivati is currently considered not to be a valid species distinct from E. acervulina ...

Poultry World webinar on Sustainable poultry farming. The latest Poultry World webinar will focus on Sustainable poultry farming. Sustainability is on everyones mind in our industry, but the subject is so broad, that its not so straightforward as it seems. In our webinar we bring theory into practice. By example, 3 speakers will show what sustainable poultry production means to them and how we can actually become more sustainable. We move away from broad statements about sound production and share actual results in day to day poultry farming.. We all underpin the global drive towards a more sustainable production. As the poultry sector provides almost 40 percent of the meat consumed worldwide, it has a major part to play in global sustainable development.

The investigations have as an aim to analyze the diversity of the microflora circulating in chickens sold in Chisinau poultry market and to identify the risk factors of contamination with pathogens. As research material were used the chicken flocks which were delivered for the sale from various poultry farms as well as from private and individual breeders from different districts of the country. Lavages of biological material for investigation were collected from the transport units which delivered chickens to the poultry market, from the cells where the chickens were held for transportation, from the floors, walls and equipment where chickens are sold. Insemination was performed on ordinary, special and differential nutrient media. After 48 hours of incubation in thermostat at + 37o C was established a trend of increasing number of colonies of the microorganisms and fungals on Petri dish where the inseminations were carried from the lavages sampling from the transport units as well from cells ...

Respiratory infection causes high economic and production losses in commercial poultry therefore, this study was conducted to record the prevalence of bacterial infection in commercial poultry farms. Out of 100 samples, nasal (n=50), tracheal (n=50) were collected from selected areas Detha, Moosa Khatian, Tando Hyder and Tando Qaisar, n= 25 from each.

The term poultry refers to domestic birds that are consumed for their meat or to produce eggs. Common forms of poultry include fowl, chicken, duck, ostrich, quail and turkey. When cutting a piece of poultry, the meatiest parts are typically found on the chest because these birds have large chest muscles that are used for flight. The next meatiest part of a bird is found on the legs, called thighs or drumsticks. Cuts of Meat The healthiest cuts of poultry meat come from the white meat. White meat is healthier to eat than dark meat because it has less myoglobin, which carries oxygen. Dark meat is located in parts of the bird's body that use the most muscles. This is why dark meat is found on the legs of birds that do not fly often, such as turkeys and chickens, yet the dark meat is found in the chest muscles of ducks and geese. Health Benefits of Poultry Poultry provides the human body with a range of nutrients and vitamins. Poultry provides the body with protein, vitamin B, including thiamin, ...

ABED, F. et al. Do broiler chicks possess enough growth potential to compensate long-term feed and water depravation during the neonatal period?. S. Afr. j. anim. sci. [online]. 2011, vol.41, n.1, pp.33-39. ISSN 2221-4062.. Broiler performance to the end of the rearing period may be negatively influenced by delayed access to feed and water immediately after hatch. This study was conducted with 320 Ross 308 broiler chicks, to evaluate the influence of delayed access to feed and water during the neonatal period (0, 16, 32 and 48 h) on performance and gastrointestinal (GIT) growth. The experiment was conducted as a complete randomized design (four replicate, each with 20 chicks). The results showed that extending post-hatch deprivation of feed and water had a significant negative impact on bird performance. Broilers deprived for 48 h had lower body weights, average daily gains and feed intakes compared to the control and to a lesser extent to the other treatments. Average daily gain, daily feed ...

The probiotic Escherichia coli Nissle 1917 enhances early gastrointestinal maturation in young turkey poults. International Journal of Poultry Science. 11(7):445-452. Interpretive Summary: Concerns over the use of antibiotics as growth promoters has led to interest in finding alternative growth promoters such as natural compounds and probiotics. Supplementing feed with probiotics has shown to enhance the gastrointestinal tract (GIT) development of chickens and turkeys. The human probiotic, E. coli Nissle 1917 (EC Nissle) has been shown to stimulate innate immunity in mammals and to increase body weight in poultry. However, the effect of this probiotic on GIT development has not been studied. The objective of this study was to evaluate the effect of EC Nissle in the maturation of the GIT of young turkey poults.

Broiler breeders require full attention. Two sexes with completely different requirements is like managing two different species in one flock.. Poultry meat is the most important animal protein source in the human diet. As a consequence, global production of broiler meat is rapidly growing to over 125 million tons in 2020. A relatively small number of broiler breeders has a major impact on the whole poultry meat chain. The continuing increase in the genetic potential of broilers makes the production of first class chicks increasingly challenging. State of the art management is crucial for a successful flock. Differences in results up to 10 day-old chicks per hen housed are not rare, costing tens of thousands of euros.. Breeder Signals contains practical information about broiler breeders to ensure a maximum production of first grade hatching eggs. With practical tools and modern insights to optimise sexual behaviour, fertility, egg production, and hatchability, based on the look-think-act ...

The long-term objective of our project will ensure the sustainability of antibiotic-restricted broiler production by enhancing bird, human and environmental health, and ultimately increasing consumer acceptability and economic ...

Vitamin nutrition is a dynamic input for the production and marketing of poultry meat and eggs. It must be updated regularly to accommodate improvements in production and marketing methods, changes in conditions on the farm and new vitamin nutrition knowledge. Continued improvement of genetic potential of poultry demands that we determine if increased vitamin levels may be needed to adequately meet these higher performance levels. The dynamics of vitamin nutrition for poultry are demonstrated by the changes in the NRC vitamin requirements of growing chickens (zero to eight weeks of age) that have been made during the past four decades. These changes were due primarily to advances in vitamin nutrition knowledge, improvements in vitamin product forms and extensive changes in commercial broiler production that have occurred during this period. Over the years, the number of vitamins recommended by NRC has increased and vitamin requirement values have been revised. The number of vitamins recommended ...

Native male turkey poults (n = 120, 49-d-old) were randomly assigned into 4 groups: poults received a basal diet with a daily subcutaneous PQ injection of 5 mg/kg BW for 7 consecutive days (PQ group), an experimental diet containing 1 g/kg PR with a daily subcutaneous PQ injection for 7 days (PR+PQ group), or received the experimental PR diet with a daily subcutaneous injection of 0.5 mL sterile saline for 7 days (PR group); while the control poults received a basal diet with a daily subcutaneous saline injection for 7 consecutive days (C group). The productive performance in the PQ group showed a significant (P , 0.05) reduction in the weight gain (WG) and feed intake (FI), and impaired feed conversion ratio (FCR). Propolis supplementation in the PR+PQ group significantly ameliorated the PQ effects on WG and FCR. Turkey poults of the PQ and PR+PQ groups had a significant augmentation in the blood malondialdehyde (MDA), tumor necrosis factor-α (TNFα), and corticosterone levels, and in ...
