　　以初始体重为12.01±0.09g的湘云鲫为研究对象,以蝇蛆培养物(CP≥65％)分别替代饲料中0％(对照组15％鱼粉,D1)、20％(D2)、33.3％(D3)、66.7％(D4)和100％(D5)的鱼粉蛋白,配制5种等氮等能实验饲料.实验在室内水循环系统中进行,每桶饲喂25尾,每个处理组3个重复,每天投喂2次(8：00和16：00),饱食投喂,试验持续10周.实验结果表明,各组存活率在97-100％之间,并无显著差异(P＞0.05).各试验组增重率均无显著差异(P＞0.05),随着饲料中蝇蛆培养物含量的增加呈现先上升后逐渐下降的趋势.各实验组肠道蛋白酶、脂肪酶及淀粉酶活性保持稳定(P＞0.05).蝇蛆培养物替代鱼粉对血清总蛋白、血糖、甘油三酯和胆...

　　This study evaluated the effects of replacing fish meal in the diet of crucian carp(initial body weight 12.01±0.09g) with maggot culture on growth,digestive enzymes and some blood physiological-biochemical indices.Five isonitrogenous and isoenergetic diets were formulated by replacing 0% (control,D1),20% (D2),33.3% (D3),66.7% (D4) and 100% (DS) with maggot culture,respectively.Each diet was randomly fed to triplicate groups of 25 fishes per tank(300L).Fish were fed to satiation twice daily(08:00 and 16:00) for ten weeks.The results showed ...
