Biotin is a water-soluble vitamin that is synthesized by ruminal bacteria. It is a vital enzyme cofactor involved in several metabolic processes including fat and carbohydrate metabolism, and protein synthesis. Because newborn calves do not have a functional rumen, they rely on biotin acquired in utero and by colostrum intake.
Providing a colostrum with optimized concentrations of biotin could be beneficial for the pre-ruminant calf growth and health. A recent study conducted at the Agriculture and Agri-Food Canada Research Centre, Quebec, Canada evaluated the effect of maternal biotin supplementation before calving on colostral and plasma concentrations in this vitamin in both the cow and the newborn calf.
