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 ...
