【摘要】 以2600只海兰蛋鸡,22头奶牛、160头商品猪及60头肉牛为试验动物,对照组在基础日粮中分别添加0.1%、0.3%及0.5%新型复合酶及微生物饲料添加剂(简称复合酶制剂)进行饲喂,结果表明,与对照相比,蛋鸡产蛋率提高13.8%,蛋重平均增加7.1 g,料蛋比明显下降,破蛋率减少,死淘率降低,育肥猪平均增重0.74 kg,较对照日增重提高12.1%,料肉比降低17%。奶牛较对照每日头均多产奶2.88 kg,产奶量提高16.6%,奶料比提高13.1%,采食量加大,消化功能增强。肉牛平均日增重较对照增加22.98%,对照组料肉比为3.46∶1,试验组为2.91∶1,料肉比降低15.9%。更多还原

【Abstract】 2600 Hyline laying hens,22 dairy cattles,160 commercial pigs and 60 beef cattles were selected as experimental animals,in control group,diets were added with new type complex enzymes 0.1%,0.3%and0.5% respectively.The results showed that compared with control group,chicken laying rate increased 13.8%,egg weight increased 7.1 g,feed egg ratio decreased significantly,broken egg rate and mortality rate decreased.Average weight gain of finishing pig was 0.74 kg,increased by 12.1% compared with control group,feed conversion decreased 17%.Dairy cattle yielded milk 2.88 kg more than control group,milk yield increased by 16.6%,milk feed ratio increased 13.1%,feed intake and digestion function improved.Average daily weight gain of beef cattle increased 22.98%,feed conversion of control group was 3.46∶ 1,feed conversion of trail group was 2.91∶ 1,feed conversion decreased 15.9%.更多还原
