| 摘 要： | 本文应用５因素２次回归几乎正交旋转组合设计，采用玉米一豆饼型饲粮（含锌３１．４５ｍｇ／ｋｇ）对４３２＊只ＡｒｂｏｒＡｃｒａ公雏〔３６组、１２只／组）的饲＊钙、负、ｖ。３、Ｂ、锌５因素进行研究，通过建立肉仔鸡体重和组织锌沉积与５因素间的回归模型、预测１０－２周龄的肉＊用仔鸡最大体重和组织锌沉积时，饲粮锌的适宜浓度。＊回归模型的数学分析结果表明：胫骨灰锌沉积与饲粮＊钙、磷、ＶＤ３、锰、锌间建立的回归方程式极显著（Ｐ＜＊０．０１）。获得最大胰脏、胫骨和血清锌沉积的饲粮锌适＊宜浓度范围为１３０－１５０ｍｇ／ｋｇ；获得最大体重的饲粮＊锌适宜浓度为８３ｍｇ／ｋｇ。本试验结果推荐０～２周龄肉用仔鸡饲粮锌的适宜浓度为８３－１５０ｍｇ／ｋｇ。

| Abstract: | Resutts indicatad that there was statistical significance (P< 0. 01) in reqression equation about rela- tionship between Zinc concentration in tibia and Calcium , Phosphorus , Vitamin D3, Manganese and Zinc in diets. To Obtain the hightost zinc concentration in Pancreas , tibia and serum,the optimal dietary Zinc levei is from 130 to 150 mg/kg. It is suggested that dietary Zinc concertration is from 83 to 150 mg/kg of broiler aged from O to 2weeks |
