摘要
本研究采用３０００羽ＡＡ肉鸡均等分组，进行两种日粮养分含量相近而鱼粉用量分别为３０％和５０％的饲喂效果对比试验，观察鱼粉中肌胃糜烂素对肉鸡生产性能的影响。结果表明，进口鱼粉３０％组的肉鸡和５０％组肉鸡４９日龄平均日增重分别为４０５３±３６６克和３５０２±３０６克，组间差异显著（Ｐ＜００５）；全期成活率分别为９４％和８８％，组间差异显著（Ｐ＜００５），后者死鸡肌胃糜烂现象较多；饲料转化率分别为２０６和２２６∶１，前者较后者提高经济效益１１５％。
Effects of containing 3 0% and 5 0% fish meal in the diet on the survial rate of broilers, the body weight gain and Feed conversion were studied. The results of this experiment were as follows: The average body weight gain was 40 52±3 66 and 35 02 ±3 06 g/d respectively, the difference is significnt(P<0 05). The survial rate of broilers was 94% and 88% respectively in significant difference(P<0 05). The feed conversion(F/G) was 2 06 and 2 26 respectivoly. It increased the production benifet 11 5%.
