Antipenicillinase in the Serum of Dairy Cows [PDF]
Acta Veterinaria Scandinavica, 1980 Serum from dairy cows was tested for inhibitory effect on penicillinase from a penicillin-resistant Staphylococcus aureus strain of mastitic origin. Among cows with subclinical mastitis caused by penicillin-resistant S. aureus there was a significantly higher frequency of individuals with penicillinajse-inhibiting serum than among healthy cows.

Machine Learning Approaches to Predict and Detect Early-Onset of Digital Dermatitis in Dairy Cows using Sensor Data [PDF]
arXiv, 2023 The aim of this study was to employ machine learning algorithms based on sensor behavior data for (1) early-onset detection of digital dermatitis (DD); and (2) DD prediction in dairy cows. With the ultimate goal to set-up early warning tools for DD prediction, which would than allow a better monitoring and management of DD under commercial settings ...

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.

Alternatives to soya for dairy cows: What are the alternatives to soya for dairy cows?
, 2021 Soybean meal is considered the gold standard for supporting high milk yields in dairy cows. However, it is falling out of favour with milk processors, consumers and dairy farmers for many reasons. Environmental concerns around how imported soybean is produced, a desire to reduce the carbon footprint of milk, and pressure from milk buyers means that ...
