The effects of stressors on lymphocyte populations and function in lactating dairy cows. Increased stress in animals can lower immune system function and hence decrease resistance to disease.
Lymphocytes are the key cells controlling the immune system.
The objectives of the study were to determine the effects of two stressors on lymphocyte function in lactating dairy cows. Data were analysed with pre-treatment values as covariates. Only minor changes occurred in lymphocyte sub-populations.
