Effect of In-vivo Heat Challenge on Physiological Parameters and Function of Peripheral Blood Mononuclear Cells in Immune Phenotyped Dairy Cattle [PDF]
arXiv, 2022 The frequency of heat waves are increasing due to climate change, which leads to an increase in the occurrence of heat stress in dairy cattle. Previous studies have shown that dairy cattle identified as high immune responders have a reduced incidence of disease and improved vaccine response compared to average and low responders.

Deep Learning-based Cattle Activity Classification Using Joint Time-frequency Data Representation [PDF]
, 2020 Automated cattle activity classification allows herders to continuously monitor the health and well-being of livestock, resulting in increased quality and quantity of beef and dairy products. In this paper, a sequential deep neural network is used to develop a behavioural model and to classify cattle behaviour and activities.

Effect of In-vitro Heat Stress Challenge on the function of Blood Mononuclear Cells from Dairy Cattle ranked as High, Average and Low Immune Responders [PDF]
BMC Vet Res 17, 233 (2021), 2021 The warming climate is causing livestock to experience heat stress at an increasing frequency. Holstein cows are particularly susceptible to heat stress because of their high metabolic rate. Heat stress negatively affects immune function, particularly with respect to the cell-mediated immune response, which leads to increased susceptibility to disease.

Longevity in Dairy Cattle [PDF]
Advances in Dairy Research, 2014 Longevity of productive life in dairy cattle is a characteristic difficult to evaluate. This measurement is complicated, in part, because the phenotype is expressed late in the life of the animal, but also because the methods of evaluation are complex. The molecular bases of longevity are still far from being fully understood, although some genes begin
