| 摘 要： | 本研究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 ,40mg/kg和160mg/kg;维生素A的添加量为1500IU/kg 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。锌、维生素A及其交互作用对各脏器的锌沉积有不同程度的影响

| Abstract: | 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;vitamin A supplement amount was 1500 and 8800IU/kg.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 serum vitamin A concentration.Zinc concentration in various organs were influenced by dietary zinc,vitamin A and there were their interaction effects in different degree. |
