Permalink Additional Niacin Improves Quality of Dairy-Cow Colostrum

Research at the New Hampshire Agricultural Experiment Station's Fairchild Dairy Teaching and Research Center showed that when dairy cows were fed supplemental niacin for four weeks pre-partum, the quality of the colostrum they produced was higher. Niacin increases rumen microbial protein production and increases blood flow, resulting in more antibody transport to the udder. Researchers found that supplemental niacin to dams increased the immunoglobulin G – the main antibody for cattle. In addition, calves fed this colostrum responded by increasing feed efficiency. According to researchers, this suggests that there is a component in colostrum that actually might stimulate intestinal development, resulting in an enhanced uptake of nutrients.
