摘　　要：畜禽维生素需要量是指畜禽维持正常生命活动、生长发育和繁殖活动所需的维生素。但随着畜牧场的规模化和集约化发展,饲料供应商或畜禽生产者对畜禽维生素的供给可能不适应实际畜禽对维生素的需要量。本文综述了影响畜禽维生素需要量的因素,即畜禽体因素、药物与饲料中的成分和维生素的稳定性,为畜禽的维生素供给提供参考。Vitamin requirements of livestock and poultry refers to vitamins required by livestock and poultry to maintain normal life activities,growth and reproduction activities.However,with the scale and intensification of livestock and poultry farms,supply of vitamins to livestock and poultry by feed suppliers or their producers may not be suitable for the actual vitamin requirements of livestock and poultry.Therefore,this article summarizes the factors affecting vitamin requirements,namely the factors of livestock and poultry,the composition of drugs and feed,the stability of vitamins,and provides a reference for the vitamin demand of livestock and poultry.
