| 摘 要： | 试验选取1日龄健康AA商品代肉鸡180羽,随机分成2组,每组3个重复,每个重复30只鸡分别饲喂含0 g/kg(对照组)、3 g/kg(酶制剂组)泰乐菌素菌渣酶制剂的玉米-豆粕型日粮42 d,研究该酶制剂对肉鸡的饲喂效果。结果表明:酶制剂组肉鸡体重和饲料利用效率均显著优于对照组(P<0.05)。酶制剂能使饲料中干物质、粗蛋白质、粗脂肪、粗纤维和粗灰分的表观消化率显著提高(P<0.05),粪中大肠杆菌数和空肠内容物黏度显著降低(P<0.05)。添加酶制剂组肉鸡腹肌、肝脏、肾脏中均未检测到残留的泰乐菌素。 |

| Abstract: | One hundred and eighty 1-day-old Arbor Acres broilers were randomly assigned into two groups with 3 replicates for 30 bird each.Two dietary treatments were corn-soybean meal diets containing 0 g/kg(control group) and 3 g/kg(enzyme group) enzyme preparation derived from tylosin dregs,respectively.The results showed that the addition of enzyme preparation to the diet significantly(P<0.05) increased the body weight and feed efficiency of broilers.Supplementation of the enzyme preparation in the diet of broiler... |
