Cortisol In Hair As A Measure Of Chronic Stress During Sow Gestation And The Pattern Of Cortisol In Blood During Parturition In Sows, Talia Everding Jan 2021

Cortisol In Hair As A Measure Of Chronic Stress During Sow Gestation And The Pattern Of Cortisol In Blood During Parturition In Sows, Talia Everding

Electronic Theses and Dissertations

Cortisol is known as the stress hormone, as it influences many metabolic processes to maintain glucose homeostasis during stressful experiences, including physical and psychological stress. It can be detected in biological matrices such as blood and hair and is released rapidly during sudden stressors and continuously during longterm stress. Blood cortisol fluctuates rapidly in response to acute stressors like pain, exertion, and fear; in hair cortisol accumulates steadily over the period of hair growth and may be useful for detecting chronically elevated cortisol resulting from long-term stress. The objective of this research was to, 1) determine the influence of a …

Viral And Immune Studies On Bovine Viral Diarrhea Virus (Bvdv) In Bovine Species, Karim Abdelsalam Jan 2021

Viral And Immune Studies On Bovine Viral Diarrhea Virus (Bvdv) In Bovine Species, Karim Abdelsalam

Electronic Theses and Dissertations

BVDV is a major pathogen of ruminants that causes immune dysfunction and lead to secondary bacterial infection. The underlying mechanism of this dysfunction is not well understood. Based on previous results, we believe that macrophages play a central role in BVDV-associated immune dysfunction. Previously, we have shown that the infected monocyte-derived macrophage (MDM) supernatant of the high virulent strains of BVDV significantly induced lymphocyte apoptosis. In the current study, we performed experiments to identify the apoptotic factors in the infected MDM supernatants in vitro. Also, we have extended our investigation to include testing the impact of infected macrophages on neutrophil …

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Food insecurity is a global problem that requires a One Health approach. As many households in low- and middle-income nations rely on crops and livestock that they produce to meet their household’s needs, food security and nutrition are closely linked to the health of animals and the environment. Resources controlled by women are more often allocated to uses that benefit the entire household, such as food, health, and educating children, than men’s resources. However, studies of gender control of resources among pastoralist societies are scant. We examined the effect of female and male control of livestock resources on food …

Maturation Of Equine Proximal Sesamoid Bones In Thoroughbred Horses, Angela Maria Mangine Jan 2021

Maturation Of Equine Proximal Sesamoid Bones In Thoroughbred Horses, Angela Maria Mangine

Theses and Dissertations--Veterinary Science

Proximal sesamoid bone (PSB) injuries account for approximately 50% of all fatal catastrophic musculoskeletal injuries in Thoroughbred racehorses. In addition, PSB fractures are not uncommon in Thoroughbred foals and yearlings as a result of energetic or intense free exercise. The ability to interpret some PSB pathology assessments, however, is more difficult given the limited information published on the normal development and maturation of these paired sesamoid bones. In addition, the level of normal variation in PSB morphological and structural parameters within the Thoroughbred population as a function of age, body size, gender, and inter-animal variation are not well documented, complicating …
