【摘要】 以鲤为试验对象,将26种能量饲料原料以8%的比例加入饲料中投喂鲤50 d,以增重率、饲料系数、成活率和生物学综合评定值为评定指标,评价26种能量饲料原料对鲤生产性能的影响。试验结果表明,在鲤增重率上,各原料间差异显著(P<0.05),增重率由小到大顺序为:蚕沙、棕榈粕、椰子粕、脱脂米糠、田菁粉、米糠、甜菜渣、小麦、苹果渣、大麦、葵花粕、标准粉、白酒糟2、次粉、苜蓿粉、麦麸、稻谷、木薯淀粉、玉米、大米、白酒糟1、土豆淀粉、西红柿粉、玉米胚芽饼、高粱、小米;饲料系数基本呈现与增重率相反的顺序,介于1.48至1.69之间,且各原料间差异显著(P<0.05);采食各种原料重量成活率均为100%,无显著性差异;生物学综合评定值与增重率基本相同。依据生物学综合评定值,能量饲料原料对鲤生产性能影响由小到大排序为:蚕沙、棕榈粕、椰子粕、脱脂米糠、田菁粉、米糠、甜菜渣、小麦、苹果渣、大麦、葵花粕、标准粉、白酒糟2、次粉、苜蓿粉、麦麸、稻谷、木薯淀粉、玉米、白酒糟1、大米、土豆淀粉、西红柿粉、玉米胚芽饼、高粱、小米。更多还原

【Abstract】 The experiment using about 58 g juvenile carp (Cyprinus carpio) was designed to test the effects of 26 energy feedstuffs on the performance of carp. Each feedstuff was added to control diets by 8% and correspondingly formed 26 test diets, performance was examined and evaluated based on weight gain, feed conversion, survival rate, and biological evaluation after feeding the carp for 50 days. There was a significant difference in weight gain between feedstuffs (P<0. 05) and the order successively : silkworm excrement, palm meal, cottonseed meal, skimmed rice bran, sesbania powder, rice bran, beetroot residue, wheat, apple residue, barley, sunflower meal, wheat flour, white brewers grains 2, wheat middlings, alfalfa meal, wheat bran, paddy, cassava amylum, corn, rice, white brewers grains 1, potato amylum, tomato powder, corn plumule cake, sorghum and millet. There was also a significant difference in feed conversion (P <0. 05) ranging from 1. 48 to 1. 69 which was opposite to the weight gain. The survival rates were 100% for each feedstuff. The biological evaluation displayed a similar order with the weight gain. According to the biological evaluation, the successive effects of energy feedstuffs on carp performance is: silkworm excrement, palm meal, cottonseed meal, skimmed rice bran, sesbania powder, rice bran, beetroot residue, wheat, apple residue, barley, sunflower meal, wheat flour, white brewers grains 2, wheat middling, alfalfa meal, wheat bran, paddy, cassava amylum, white brewers grains 1, corn, rice, potato amylum, tomato powder, corn plumule cake, sorghum, and millet.更多还原
