Journal of Dairy Science, 2019 The digestive physiology of ruminants is sufficiently different (e.g., with respect to mean retention time of digesta, digestibility of the feed offered, digestion, and fermentation characteristics) that caution is needed before extrapolating results ...

An analysis of the 1948 Jersey heifer registration data to provide information concerning some features of New Zealand pedigree Jersey cattle [PDF]
, 1952 At present there is a lack of information concerning the breeding methods practised by owners of pedigree dairy cattle in New Zealand. This deficiency is a serious handicap in attacking some of the major problems facing the dairy industry in this country.

Journal of Dairy Science, 2019 Milk pH is increased in lactating dairy cattle with subclinical mastitis (SCM) and intramammary infection (IMI). We hypothesized that milk pH testing provides an accurate, low-cost, and practical on-farm method for diagnosing SCM and IMI.

Real-Time Cattle Interaction Recognition via Triple-stream Network [PDF]
arXiv, 2022 In stockbreeding of beef cattle, computer vision-based approaches have been widely employed to monitor cattle conditions (e.g. the physical, physiology, and health). To this end, the accurate and effective recognition of cattle action is a prerequisite. Generally, most existing models are confined to individual behavior that uses video-based methods to

Skid resistance and durability of coated and uncoated concrete floors in dairy cattle buildings [PDF]
, 2011 Passageways in cattle buildings should provide durable and non-slippery surface to allow cattle an unrestrained locomotion and expression of behaviour.

Applied and Environmental Microbiology, 2018 This study revealed the rumen bacteriome from a large dairy cattle cohort (n = 334) raised under the same management and showed the linkages among the rumen core and pan bacteriomes, rumen short-chain fatty acids, and milk production phenotypes.

JDS Communications, 2021 There has been increasing interest in residual feed intake (RFI) as a measure of net feed efficiency in dairy cattle. Residual feed intake phenotypes are obtained as residuals from linear regression encompassing relevant factors (i.e., energy sinks) to ...

Estimation of Gaussian directed acyclic graphs using partial ordering information with an application to dairy cattle data [PDF]
arXiv, 2019 Estimating a directed acyclic graph (DAG) from observational data represents a canonical learning problem and has generated a lot of interest in recent years. Research has focused mostly on the following two cases: when no information regarding the ordering of the nodes in the DAG is available, and when a domain-specific complete ordering of the nodes ...

Symposium review: Novel strategies to genetically improve mastitis resistance in dairy cattle.
Journal of Dairy Science, 2018 Mastitis is a disease of major economic importance to the dairy cattle sector because of the high incidence of clinical mastitis and prevalence of subclinical mastitis and, consequently, the costs associated with treatment, production losses, and reduced
