Relationships Between Animal Temperament And Systemic Immune Responses In Beef Cattle Exposed To Conditions Associated With Conventional Management, Alexander W. Altman
Relationships Between Animal Temperament And Systemic Immune Responses In Beef Cattle Exposed To Conditions Associated With Conventional Management, Alexander W. Altman
Theses and Dissertations--Animal and Food Sciences
Measures of temperament have been shown to influence physiological responses. Exit velocity (EV) has been identified as an objective, robust measure of temperament that can be used to predict subsequent performance of cattle. Additionally, previous studies from our lab indicate this measure of temperament may be related to production of interferon-γ (IFN-γ), a cytokine associated with cell-mediated immunity (CMI). Whereas research has investigated effects of EV upon immune responses, the overall goal of these studies was to examine this relationship under a variety of scenarios including human handling, transportation, and exposure to endophyte-infected tall fescue (E+) for determination of its …
Lymphocyte-Mediated Inflamm-Aging In The Horse, Melissa Hope Siard
Lymphocyte-Mediated Inflamm-Aging In The Horse, Melissa Hope Siard
Theses and Dissertations--Veterinary Science
Senior horses (≥20 years) exhibit inflamm-aging, or chronic, low-grade inflammation that occurs systemically with aging, similarly to humans. Inflamm-aging has previously been characterized in the horse in circulation as well as specifically being mediated by lymphocytes and monocytes. In humans, inflamm-aging has been associated with increased morbidity and mortality. However, in the horse, relatively little about inflamm-aging is known regarding clinical effects or factors influencing severity. The contribution of lymphocytes to inflamm-aging of senior horses was examined, specifically through determining the relationships of inflamm-aging with various other health parameters, effects of seasonality, and the extent to which inflamm-aging can be …
