【摘要】 研究了四种加酶饲料（基础饲料（ＣＫ）、基础饲料＋１％淀粉酶、基础饲料＋０．５％胃蛋白酶、基础饲料＋１％淀粉酶＋０．５％胃蛋白酶）对肉用仔鸡增重、饲料转化率及血液中某些生理生化指标的影响。结果表明：加酶饲料对肉鸡的增重分别比对照提高４．４０％、５．９５％、７．５０％，饲料转化率分别比对照提高３．７６％、７．５３％、１３．９８％，其中加二酶复合制剂组的增重效果显著（Ｐ＜０．０５），加酶饲料对肉鸡的血红蛋白、血浆总脂类、ｒ－球蛋白的含量没有影响（Ｐ＞０．０５），饲料中加淀粉酶制剂可使血糖明显升高（Ｐ＜０．０５）。使用二酶的复合制剂可使血浆总蛋白、清蛋白、α１－球蛋白明显升高（Ｐ＜０．０５）。更多还原

【Abstract】 The effects of four feeds with enzymes( foundamental feed,foundamental feed + 1% amylase,foundamental feed + 0 5% pepsin, foundamental feed + 1%amylase+ 0 5% pepsin) were studied on the gain weight,feed conversion rate and some physiological and biochemical index in blood of broiler chicks. The results showed that the gain weights and feed conversion rates of the treatments are higher 4 40%,5 95%,7 50% and 3 76%,7 53%,13 98% than those of CK respectively,Only the improvenent of gain weight in the group adding two enzyme compounds is remarkable(P<0 05). The contents of hemoglobin,tatol lipids,γ globulin in the blood or plasma of broilers is not influenced by the adding enzyme feed(P>0 05). The adding anylase feed can have blood sugar content of broiler risen remarkably(P<0.05) . Using two enzyme compound can reslult in the stricking rise of content of total protein,albumin,α 1 globulin in plasma.The amylase or pepsin alone can result in stricking rise of α 1 globulin content only(P<0 05) .更多还原
