A series of in vitro studies tested effects of nicotinic acid on rumen fermentation. Urea was the nitrogen supplement for all substrates. As expected, a substrate of corn produced the most gas and microbial protein followed by a substrate of corn plu

The effect of nicotinic acid (niacin) on microbial fermentation was tested in vitro. Microbial protein synthesis was greater with niacin and soybean meal than with niacin and urea. Otherwise, in most instances niacin decreased synthesis with urea. Th

Cattle fed heated soybean meal as a protein supplement had lower rumen protozoal counts than did those fed unheated soybean meal. Adding niacin to unheated soybean meal increased protozoal counts, but the difference was not significant. Adding niacin

In two experiments with Holstein cows effects of dietary supplementation of niacin to periparturient cattle on subsequent milk production and ketosis were examined. In Experiment 1, 20 cows were assigned to two groups. The treatment group received ni
