摘要
试验旨在研究葡萄糖氧化酶(Glucose Oxidase,GOD)和过氧化氢酶(catalase,CAT)复合酶制剂降解污染饲料中黄曲霉毒素B1(Aflatoxin B1,AFB1)对蛋鸡生产性能和蛋品质的影响。选用210只180日龄京粉蛋鸡,随机分为7组(CK、BA1、BA2、BA3、BD1、BD2和BD3),7个处理组分别是饲喂不添加污染玉米和复合酶的CK组,污染饲料中含有17.22,53.27和134.56μg/kg AFB1的BA1,BA2和BA3组,在有毒玉米中添加0.5%复合酶的BD1、BD2和BD3组。结果显示,蛋鸡的生产性能和蛋品质在BA1、BA2和BA3组均有不同程度下降,在BD1、BD2 3期(T1,T2和T3)和BD3组第1期(T1)均达到对照组水平,BD3组第3期与BA3组同期相比,蛋鸡月产量从9枚提高到17枚,受精蛋孵化率从41%提高到57%,蛋黄重量从14.34 g提高到15.53 g,单枚蛋重从42.39 g提高到48.49g,蛋壳厚度从0.28 mm提高到0.31 mm。由此可知,复合酶制剂基本消除或减轻了AFB1对蛋鸡生产性能和蛋品质不良影响。
In this study, we investigated effects of aflatoxin B1 degradation complex enzymes（GOD and CAT） on production perform-ance and egg quality of laying hens fed with naturally moldy corn with AFB 1 .Two hundred and ten 180-day-old Jing Fen laying hens were randomly divided into seven groups （CK, BA1, BA2, BA3, BD1, BD2 and BD3） .The seven dietary treatments consisted of con-ventional feed without moldy corn or complex enzymes as a control diet （CK）, AFB 1 content of moldy corn were 17.22,53.27 and 134.56 g/kg （BA1, BA2 and BA3）, respectively and moldy corns were added into 0.5%complex enzymes（BD1, BD2 and BD3）. Results showed the production performance and egg quality of laying hens in BA 1,BA2 and BA3 groups were all decreased in different degrees, the production performance and egg quality of laying hens in BD 1,BD2 groups at three phases（T1,T2 and T3） and BD3 at the first phase（T1） of experimental time continuously were all increased compared to that in CK groups .In BD3 group was compared with in BA3 group at third phase（T3） of experimental time continuously , and the monthly output of eggs has gone up from 9 to 17, the hatching rate of fertilized eggs has gone up from 41%to 57%, the yolk weight has gone up from 14.34 g to15.53 g , the egg weight＆nbsp;has gone up from 42.39 g to 48.49 g, the eggshell thickness has gone up from 0.28mm to 0.31mm.As a result , the complex enzymes could reduce or almost eliminate the negative effects of AFB 1 on production performance and egg quality of laying hens .
