Effects of biotin and nicotinamide supplementation on glucose and lipid metabolism and milk production of transition dairy cows
Introduction Due to the insufficient DMI andendocrine-induced adaptations, transition dairy cows are in the negative energy balance (NEB) status (Bobe et al., 2004),leading the animals susceptible to hepatic lipidosis and ketosis (Contreras and Sordillo, 2011).Dairy cows obtain 70％ of their glucose requirement fromhepatic gluconeogenesis during transition (Aschenbach et al., 2010).Biotin (BIO)and nicotinamide (NAM)function as cofactors playingvital roles ingluconeogenesis process.Therefore, the objectives of the study were (1) to determine if supplementing ruminally unprotected NAM at a high dose to transition dairy cow elicitseffect,and (2) to evaluate combined BIO and NAM supplementation for their effects and interactionson energy metabolism and milk production.
