Evaluating Colostrum Quality With Niacin Supplementation In The Diet Of Dairy Cattle, Allison Marie Pike
Evaluating Colostrum Quality With Niacin Supplementation In The Diet Of Dairy Cattle, Allison Marie Pike
Student Research Projects
Dairy calves are born with a naive immune system, and must obtain passive immunity through ingestion of colostrum. Colostrum provides the newborn with antimicrobial proteins called immunoglobulins, such as immunoglobulin G (IgG), that protect the calf for the first few weeks of life. Calves that receive good quality colostrum (>50 g/L of IgG) are more likely to survive to adulthood. Niacin is a vasodilator that may increase blood flow to the mammary gland during production of colostrum in the mother. This experiment investigated the effect of niacin supplementation at a rate of 48 g/cow/day for 3 weeks before calving …

Infertility, often attributed to follicular atresia, is a growing problem in the agricultural industry. Programmed cell death, also known as apoptosis, is a contributing factor of follicular atresia. It occurs in both the granulosa cells and the oocyte that comprise ovarian follicles. Here, mechanisms influencing the process of apoptosis, via the death receptor Fas, were explored using bovine granulosa cells (bGCs) because Fas-induced apoptosis is a plausible mechanism of follicular atresia. Cell culture techniques, optimized for bGCs, were developed and used throughout the current study. In brief, cultures of bGCs were exposed to Fas ligand (100ng/mL) for 24 hrs. This …
