摘　　要：试验选用1日龄罗斯308肉鸡256只,随机分成4组,每组4个重复,每重复16只鸡。分别饲喂正对照组(试验1组)基础日粮;负对照组(试验2组)基础日粮(降低代谢能0.21MJ/kg);负对照组日粮+200 g/T酶制剂(试验3组)、负对照组日粮+400 g/T复合酶制剂(试验4组)。试验结果如下:肉鸡日粮中添加NSP酶制剂对肉仔鸡血液生理生化指标有影响,可提高28日龄、45日龄肉仔鸡血清葡萄糖的含量(P<0.05),NSP酶制剂对血清总蛋白含量的影响差异不显著(P>0.05)。NSP酶制剂可降低28日龄、45日龄肉仔鸡血清总胆固醇含量(P<0.05)。NSP酶制剂对血清尿酸含量的影响差异不显著(P>0.05)。NSP酶制剂对血清钙、磷含量的影响差异不显著(P>0.05)。NSP酶制剂可提高28日龄、45日龄肉仔鸡血清T3的含量(P<0.05)。NSP酶制剂对28日龄血清肉仔鸡T4水平的影响差异不显著(P>0.05);NSP酶制剂可提高45日龄肉仔鸡血清T4水平(P<0.05)。NSP酶制剂对28日龄血清肉仔鸡GH水平的影响差异不显著(P>0.05),NSP酶制剂可提高45日龄肉仔鸡血清GH水平(P<0.05)。256 1 - day - old health Ross 308 broilers were randomly divided into 4 groups with four replicates each treatment having 16 chickens each replicate. In this study, the broilers which in test 1 were feed the com - soy - miscellaneous diets with normal level energy; the broilers which in test 2（ negative control） were feed the corn - soy - miscellaneous diets which reducing 0.21 MJ/kg AME; the broilers which in test 3 and 4 add 200g/T,400g/T commercial NSP enzyme separately, The results indicated that： According to different levels of enzyme added to the diet of broiler, that can reduce the amount of vegetable oil to reduce feed costs, at the same time, that cart promote the phase of weight gain and lower feed / gain and improve the survival rate. test 3,4 average daily weight gain, feed weight ratio is superior to of group 2 at all different levels. NSP enzymes can increase 28 - day - old, 45 - day - old broiler serum glucose levels（P 〈0.05） , there is no significant affect on serum total protein content（ P 〉 0.05）. NSP enzymes can reduce the 28 -day -old, 45 -day -old broiler serum total cholesterol （P 〈 0.05）. there is no significant effect on serum serum uric acid content （ P 〉 0.05 ）. NSP enzymes on serum calcium, phosphorus content of no significant difference （ P 〉 0.05 ）. Enzymes can increase 28 - day - old, 45 - day - old broiler serum T3 levels （ P 〈 0. 05 ）. NSP enzymes to 28 - day - old broiler serum T4 levels were no significant differences （ P 〉 0.05 ） ; Enzyme can increase 45 - day - old broiler serum T4 level （ P 〈 0.05 ）. Enzyme to 28 - day - old broiler serum GH levels not significantly different （ P 〉 0.05 ）, Enzyme can increase 45 - day - old broiler serum GH levels （ P 〈 0.05 ）.
