Biotin rocks! That is the conclusion from a meta-analysis done by researchers at Zhejiang University in China and reported in the July edition of the Journal of Dairy Science.

The meta-analysis of nine studies indicated that biotin supplementation of diets of lactating cows resulted in increased dry matter intake, milk yield, milk fat, and protein yield, the authors said. Milk production increased by a weighted average of 1.66 kilograms per day, or 3.65 pounds per day. (In seven of the nine studies, the dosage of biotin was 20 milligrams per cow per day.) Yet, biotin supplementation had no significant effect on the percentage of milk fat and milk protein.
