【摘要】 试验选用1日龄艾维茵雏鸡300只,随机分为3组,每组3次重复,用以观测日粮中添加热炒全脂大豆和复合酶制剂对肉仔鸡生产性能的影响。结果表明:(1)热炒全脂大豆组(占日粮6.7%)较豆饼组(占日粮8.0%)提高肉仔鸡4～7周龄体质量6.3%(P>0.05),饲料利用率提高16.3%(P<0.05);(2)日粮中添加酶制剂可提高饲料利用率(P<0.05)、0～7周龄体质量(P>0.05)和经济效益。更多还原

【Abstract】 An experiment was conducted using 300 Avine broilers at 1 day of age to investigate the effects of heat processed fullfat soybean and composite enzyme preparation on the production performance of broilers.The broiler was randomly divided into 3 groups,and each group was represrented by three repilates.The results showed that:(1)Birds fed diets added with heat processed fullfet soybean presented 6.3% better values of body weight gain during a phase of 47 weeks(P>0.05),and 16.3 % better values of feed conversion (P<0.05)than diets of 8.0% soybean cake;(2)Composite enzyme preparation added into the broilers diets increased feed conversion(P>0.05) body weight gain during a phase of 0-7 weeks (P>0.05) and economil benefits.更多还原
