Host response to invasive microbes in the bovine udder has an important role on the animal health and is essential to the dairy industry to ensure production of high-quality milk and reduce the mastitis incidence. (bvsalud.org)
Staphylococcus aureus (S. aureus) is a major mastitis-causing pathogen in dairy cows. (bvsalud.org)

Furthermore, SBM is an excellent source of RDP and up to 65% of rumen degradability by rumen microbes ( 7 ). (frontiersin.org)
Genus-level abundances of rumen microbes showed low-to-moderate heritability and repeatability and were consistent between diets. (biomedcentral.com)

Our research is helping industry maximise the potential of these high-performing animal feeds and farmers to correctly incorporate them in cows' diets. (nottingham.ac.uk)
The ram press sunflower cake, in particular is an option that may be used by smallholder dairy farmers to formulate local dairy concentrate, which influence dairying to a similar extent as the commercial dairy concentrate but cheaply. (scialert.net)
Milk Specialties Global has been providing nutritional solutions to dairy farmers for nearly 80 years. (feedstuffs.com)
Cow infertility is a major productivity problem for farmers with high-yielding dairy cows. (ciwf.org.uk)
Usually farmers are breeding cows around 60 to 70 days after calving, but if it is unsuccessful, it's often because of events like metritis or subclinical endometritis that happen prior to breeding, earlier in the cycle. (iowaagconnection.com)

The dairy sector has been under a magnifying glass for many years regarding its effect on the environment, in particular its contribution to the emission of greenhouse gasses. (allaboutfeed.net)
Dairy cows emit high levels of methane (CH4) which is a major source of greenhouse gas and therefore possesses detrimental effects to the environment. (wur.nl)

It has been suggested that specific supplements such as rumen-degradable carbohydrates be offered to reduce these losses. (fao.org)

Background Negative energy balance during the transition period is a concern for both conventional and certified organic dairy systems. (researchsquare.com)

Metagenome profiles were generated by RE-RRS of 4,479 rumen samples collected from 1,708 sheep, and assigned to eight groups based on diet, age, time off feed, and country (New Zealand or Australia) at the time of sample collection. (biomedcentral.com)

Learn more about the role of rumen microorganisms and their impact on the host's performance and health. (lallemandanimalnutrition.com)
The host's rumen microbiome plays a vital role in converting consumed feed into short chain fatty acids, which provide energy to the host but also produce methane as a by-product. (biomedcentral.com)

To better understand the biology behind these host-microbiome interactions, we investigated the somatic cell proteomes at quarter level for four cows (collected before and after milking) using a shotgun proteomics approach. (bvsalud.org)

Corn grown during the summer of 2014 was ensiled and fed to dairy cows, while corn grown during the summer of 2015 evaluated the plant and corn silage. (illinois.edu)
Concentration of milk lactose tended to be greater for cows fed corn silage treated with foliar fungicide when compared with CON. (illinois.edu)

From two to three weeks before calving, you should gradually introduce the cows to the production ration (i.e. the phased introduction of the higher energy, post-calving diet) to avoid a sudden change of diet. (gov.scot)
