【摘要】 甲鱼及大黄鱼苗期添加“86 8”(微生物发酵产物 )可促进鱼体生长 ,增强机体免疫力 ,从而达到提高产量及成活率的效果。试验结果表明 :甲鱼苗期在饲料中添加 0 .3%～ 0 .6 %的“86 8”粉剂喂养 80d～ 1 32d ,成活率提高 1 3.96 %～ 31 .75 % ,增重率提高 1 7.8%～ 32 .6 % ,投入添加剂与增产值比较 1∶4.6～ 1 3.73;大黄鱼苗期在饲料中添加 0 .5 %的“86 8”粉剂喂养 1 0 7d ,体长增长 1 5 .38% ,增重率提高 1 4 .2 9% ,具有明显的社会经济效益。更多还原

【Abstract】 Adding the bacterium product 868 during the young period of Trionyx sinensis and Pseudosciaena crocea can increase the production and the survival rate by stimulating the growth and enhancing the immunity of the body. The experiment results show that: adding 868 at 0.3%～0.6% of the fodder during the young period of Trionyx sinensis for 80～132 d, the survival rate increases by 13.96%～31.75%,the production increases by 17.8%～32.6% and the ratio of feed additive and production increase is 1∶4.6～13.73; adding 868 at 0.5% of the fodder during the young period of Pseudosciaena crocea for 107 d, the length of the body increases by 15.38% and the production increases by 14.29%. 868 as feed additive has obvious social and economic benefit.更多还原
