An Update on B Vitamin Nutrition for Cattle

B vitamin supplementation in ruminants is ignored conventionally following an earlier observation that they are synthesized in adequate quantities in the rumen by rumen microbes. Recent researchers reported that major cellulolytic organisms in the rumen had specific requirements for certain B vitamins. Apart from the requirements of the rumen microbes, high producing cattle also require a higher amount of vitamins to maintain their productivity and health. Sub-clinical vitamin deficiencies often go unnoticed due to the lack of proper clinical symptoms. The present review aimed at providing an update on B vitamin nutrition to cattle.
