摘要 将90只37周龄AA父母代种母鸡随机分为3组,每组30只,1组为对照组,饲喂玉米—豆粕型基础日粮,2组和3组为试验组,分别饲喂含甜菜碱100毫克/千克和200毫克/千克的基础日粮7周,限制饲养。测定每组鸡的产蛋率、平均蛋重、料蛋比和种蛋孵化率。结果表明:2组的产蛋率分别比1组和3组提高8.17和6.6个百分点(P<0.01),2组和3组的耗料分别比对照组降低2.4%和6.1%,3组的入孵蛋孵化率比1组提高5.9个百分点(P<0.05)。 For 7 weeks 90 AA broiler breeders,initially 37 weeks old,were given a diet based on corn soybean meal diet without or with betaine 100 mg/kg or 200 mg/kg,restricted feeding.Laying rate,average egg weight,egg-feed ratio and hatchability were determined.Laying rate in the group given 100 mg/kg was improved by 8.17 per cent(vs the controls,P<0.01) or 6.6 per cent(vs the group given 200mg/kg,P<0.01) respectively.Egg-feed ratio in the group given 100 mg/kg or 200 mg/kg decreased by 2.4% or 6.1% than the controls respectively.Hatchability in the group given 200 mg/kg was improved by 5.9 per cent than the controls (P<0.01).Average egg weight showed no significant difference among three groups.
