葡萄糖氧化酶对蛋鸡产蛋性能及血液生化指标的调控作用

Effect of Glucose Oxidase on Performance and Serum Biochemical Parameters of Laying Hens

采用单因子随机分组试验设计，将180只26周龄海兰褐蛋鸡随机分为5组，每组4个重复，研究葡萄糖氧化酶对产蛋性能及血液生化指标的调控作用。结果表明，日粮中添加0．1％，0．2％，0．3％，0．4％的葡萄糖氧化酶，与对照组相比，产蛋率分别提高了11．01％（P〉0．05），12．34％（P〉0．05），16．06％（P〈0．01），13．79％（P〈0．05）；破软蛋率分别降低了32．77％（P〉0．05），33．45％（P〉0．05），49．66％（P〈0．05），33．11％（P〉0．05）；O．3％和0．4％葡萄糖氧化酶添加组显著提高了饲料转化率（P〈0．05）。13粮中添加0．4％葡萄糖氧化酶可显著提高血清总蛋白含量，O．2％～0．4％葡萄糖氧化酶可显著或极显著提高白蛋白的含量。0．1％．0．4％葡萄糖氧化酶有提高球蛋白、钙磷和碱性磷酸酶的含量，降低总胆固醇和甘油三酯水平以及提高谷丙转氨酶和谷草转氨酶的活性的趋势，但未达显著水平（P〉0．05）；0．4％添加组显著降低了肌酸激酶的活性（P〈0．05）。

This experiment was to investigate the effect of Glucose Oxidase on and serum biochemical parameters of laying hens. 180 twenty-six-week-old Hyline layers were randomly allotted to 5 treatments, Laying Hens in treatments Ⅰ,Ⅱ, Ⅲ,Ⅳ and Ⅴ received basal diets with the addition of 0,0.1% ,0.2% ,0.3% ,0.4% glucose oxidase. The results shows that laying hens fed the addition of 0.1% ,0.2 %, 0.3 %, 0.4 % glucose oxidase, compared with the control group, the egg production increased by 11.01 % （ P 〉 0.05）, 12.34% （ P 〉 0.05）, 16.06% （ P 〈 0.01 ）, 13.79% （ P 〈 0.05） ; the broken （soft） eggshell rats decreased by 32.77 % （ P 〉 0.05 ）, 33.45 % （ P 〉 0.05 ）, 49.66 % （ P 〈 0.05 ）, 33.11% （ P 〉 0.05 ） ; the additions of 0.3% and 0.4% glucose oxidase significantly enhance（ P 〈 0.05） the feed conversion ratio. Laying hens fed the addition of 0.2% ~ 0.4% glucose oxidase significantly increased the serum ALB ,and had the trend of increasing the in serum GLO, Ca, P, AKP, GPT and GOT, and reducing the serum CHOL and TG, but the differences were not significant （ P 〉 0.05）.The addition of 0.4% glucose oxidase significantly reduced the levels of CK（ P 〈 0.05）.
