Heat stress affects dairy cow health status through blood oxygen availability

Journal of Animal Science and Biotechnology, 2023
Background Rises in global warming and extreme weather occurrence make the risk of heat stress (HS) induced by high ambient temperatures more likely in high-yielding dairy cows, resulting in low milk quality and yield.

Invited review: A systematic review of the effects of early separation on dairy cow and calf health

Journal of Dairy Science, 2019
Concern from the public is growing regarding early cow-calf separation, yet proponents of this practice maintain that artificial rearing is critical for cow and calf health. Early separation is assumed to reduce the risk of transfer of pathogens from dam

Silage review: Silage feeding management: Silage characteristics and dairy cow feeding behavior.

Journal of Dairy Science, 2018
Feeding environment and feed accessibility influence the dairy cow's response to the ration and forage composition. Fiber content, physical form, and fermentability influence feeding behavior, feed intake, and overall cow metabolic and lactational ...

Invited review: Sphingolipid biology in the dairy cow: The emerging role of ceramide.

Journal of Dairy Science, 2019
The physiological control of lactation through coordinated adaptations is of fundamental importance for mammalian neonatal life. The putative actions of reduced insulin sensitivity and responsiveness and enhanced adipose tissue lipolysis spare glucose ...

Characterization of the on-body path Loss at 2.45 GHz and energy efficient WBAN design for dairy cows [PDF]

, 2016
Wireless body area networks (WBANs) provide promising applications in the healthcare monitoring of dairy cows. The characterization of the path loss (PL) between on-body nodes constitutes an important step in the deployment of a WBAN.

Animal board invited review: Dairy cow lameness expenditures, losses and total cost.

Animal, 2018
Lameness is one of the most costly dairy cow diseases, yet adoption of lameness prevention strategies remains low. Low lameness prevention adoption might be attributable to a lack of understanding regarding total lameness costs.

Resveratrol affects in vitro rumen fermentation, methane production and prokaryotic community composition in a time‐ and diet‐specific manner

Microbial Biotechnology, 2020
Summary This study aimed to investigate the effect of resveratrol on methane production, rumen fermentation and microbial composition under high‐concentrate (HC) and high‐forage (HF) diets using the in vitro fermentation system.

Metatranscriptomics Reveals the Active Bacterial and Eukaryotic Fibrolytic Communities in the Rumen of Dairy Cow Fed a Mixed Diet

Frontiers in Microbiology, 2017
Ruminants have a unique ability to derive energy from the degradation of plant polysaccharides through the activity of the rumen microbiota. Although this process is well studied in vitro, knowledge gaps remain regarding the relative contribution of the ...

LPS-induced reduction of triglyceride synthesis and secretion in dairy cow mammary epithelial cells via decreased SREBP1 expression and activity.

Journal of Dairy Research, 2018
Sterol regulatory element binding protein 1 (SREBP1) has a central regulatory effect on milk fat synthesis. Lipopolysaccharides (LPS) can induce mastitis and cause milk fat depression in cows.
