The invention discloses a product for adding nicotinamide / or nicotinic acid to perinatal milk goats to enhance antioxidant and immune function of lambs and a use method and application thereof and belongs to the technical field of nutrient feed additive for milk yielding animals. Specifically, adding of nicotinamide to the perinatal milk goats has not effect on lambs' birth weigth and growth and development at the age of 28 days, and length of pregnancy of ewes is unaffected; however, antioxidant and immune capacity of the lambs are remarkably improved, and a foundation for exploring the regulatory effect of maternal B-group vitamin niacinamide nutrition on offspring is laid.
Description
technical field [0001] The invention belongs to the technical field of nutritional feed additives for dairy animals, and in particular relates to a product, method and application for enhancing the antioxidant and immune functions of lambs by adding nicotinamide / or nicotinic acid to dairy goats in the perinatal period. Background technique [0002] The perinatal period is one of the most critical physiological periods for dairy animals. During this period, the production cycle changes from pregnancy to childbirth, and then to lactation. Physiology, nutrition, metabolism and immunity change greatly, and metabolic and infectious diseases occur frequently. Moreover, the appetite of dairy animals will be suppressed in the late pregnancy, and the postpartum dry matter intake cannot meet the nutritional needs. Decreased energy intake due to reduced dry matter intake in dairy animals, coupled with increased energy requirements due to embryonic growth and lactation, lead to a negati...
