摘　　要：以艾维因肉仔鸡为模型，采用２×３（ＶＡ×Ｚｎ）实验设计来探讨肉仔鸡体内锌对维生素Ａ代谢的影响。锌的添加量为０、４０和１６０ｍｇ／ｋｇ；维生素Ａ的添加量为１５００和８８００ＩＵ／ｋｇ。结果证明在肉仔鸡体内锌对动员肝脏维生素Ａ入血有重要作用；日粮锌和维生素Ａ水平对血清维生素Ａ浓度有互补作用。The purpose of the experiment was to study the vitamin A metabolism in broilers with different dietary zinc and vitamin A levels. Zinc supplement amount was 0.40 and 160mg/kg; viamin A supplement amount was 1500 and 8800IU/kg. The results showed that with the increasing of dietary zinc level vitamin A concentration in serum increased significantly and dietary zinc and vitamin A level had mutual supplement effect on vitamin A concentration in serum.
