膨化饲料中豆粕替代鱼粉对建鲤生长性能、体成分和消化吸收功能的影响
The Influence of Replacing Fish Meal with Soybean Meal on Growth,Body Composition and Digestive Ability of Jian Carp in Practical Extruded Diets
摘要
Abstract
The present study was performed to investigate the effect of replacing fish meal with soybean meal on growth,body composition and digestive ability of Jian carp.A total of 720 Jian carp with average initial weight of (240.2 ±5.7) g were randomly allocated four groups of each three replicates.Four isonitrogenous and isoenergetic practical extruded diets were formulated by replacing 0,25%,50%,and 100% fish meal with soybean meal.The results showed that there was no significant difference in the percent weight gain(PWG) and the specific growth rate(SGR) in fish fed diets by replacing 0,25%,and 50% fish meal with soybean meal.(P >0.05).Fish fed the diet by replacing 100% fish meal with soybean meal had significantly lower PWG and SGR than the 0 group(P <0.05).The crude protein in whole body were significantly lower when the replacement ratio of fish meal by soybean meal was 100%(P <0.05).Fish fed the diet by replacing 100% fish meal with soybean meal had significantly low-er,γ-GT and AKP than the 0 group(P <0.05).These results indicated there was no significant difference on growth performance of juvenile Jian carp at body weight 200 -800 g when soybean meal could be used by replacing 50% of fish meal in practical extruded diets.关键词
