摘　　要：本研究应用５因子５水平部分实施的２次回归几乎正交旋转组合设计，采用玉米－豆粕型基础日粮和４３２只ＡＡ（ＡｒｂｏｒＡｃｒｅｓ）肉用公雏，研究日粮中锰（Ｍｎ）、锌（Ｚｎ）、钙（Ｃａ）、有效磷（ａｖ．Ｐ）、维生素Ｄ３（ＶＤ３）５因素不同添加水平的组合效应，探讨５因素与指标间的相互关系。结果表明，由二次响应面分析得出的生产函数二次曲线稳定点的预测值为３５８．７１，对应５因素组合的预测值分别为Ｃａ＝１．０１％，ａｖ．Ｐ＝０．４９％，ＶＤ３＝２１１０．７５１ＩＵ／ｋｇ，Ｍｎ＝１４１．２５ｍｇ／ｋｇ，Ｚｎ＝１７５．８５ｍｇ／ｋｇ，Ｃａ、ａｖ．Ｐ、Ｚｎ是影响生长的主因素；肉雏鸡日粮中Ｃａ、ａｖ．Ｐ、Ｍｎ、Ｚｎ、ＶＤ３任一因素的添加水平过高都会影响其它４营养素的吸收和利用；Ｍｎ－ＳＯＤ、肝锰、肾锰以及血清钙和磷、肝锌分别是反映Ｍｎ、Ｃａ、ａｖ．Ｐ、Ｚｎ营养状况的敏感指标。According the second order regression,nearlyorthognal roatable composition five factoral designs,study the requirements of calcium,phosphorus,vitamin D 3 manganese and zinc with 432 one day old Arbor Acres(AA)male broiler chicks,36 groups of 12 replication (control groups from 27 to 36).Body weight(BW),feed conversion efficiency(feed/gain),manganese superoxide dismutase(Mn SOD)activity of heart tissue,Ca,av.P,Zn in serum and tibia and Mn in liver,pancreas etc.,were detected,and built math models between indicators and five nutritional factors ,predicts the performance in broiler chicks and the optimum levels of supplementation in five factors ,and probes the each other relationships among five factors and indictors.Results indicated that the predicted weight was 358.71g ,Ca= 1.01% ,av.P=0.49%,VD 3=2110.75IU/kg,Mn=141.35mg/kg,Zn= 175.85mg/kg ,respectivelyWhen Anyone of five factors was excess,absorption of other factors was depressed.Manganese concentration in kidney and spleen,Mn SOD activity,Ca,av.P in serum,and Zn in liver were sensitive indictors reflected the nutritional situation of five factors.Mn concentration in spleen,pancreas and kidney,Zn concentration in spleen,liver and tibia,av.P in serum and tibia,and Ca in serum were related significantly,respectively.(P<0.05～0.001).
