Analysis and publication of research data on Johne’s Disease in dairy cattle
Johne’s Disease is a chronic wasting disease in cattle and other ruminants caused by a bacterium. Due to the long incubation period of the disease, it can take several years…

Interactions of fibroblast growth factor and protein metabolism during the postpartum period in lactating dairy cows and their effect on animal health.
The immediate postpartum period in lactating dairy cattle is the time when cows are most vulnerable to metabolic disorders such as ketosis and fatty liver. These disorders often predispose the…

Harnessing the power of computer vision systems to improve animal health and welfare in transition dairy cows
Nearly all cows will experience negative energy balance in order to support the high energy demands of lactation during the transition period. This can lead to a variety of metabolic…

Improving health and welfare of dairy cattle by synchronizing and optimizing the transition period
Calving and transition to lactation increases susceptibility to and incidence of disease in the dairy cow. In dairy and beef farms, calvings occur in a wide range before and after…

The genetic determinants of gastrointestinal tract colonization by Listeria monocytogenes
Listeria monocytogenes (Listeria) is a dangerous foodborne pathogen commonly associated with dairy product outbreaks. Listeria infection has remarkably high hospitalization and mortality rates, thus the FDA implements a zero-tolerance policy for…
