摘要
该试验研究使用不同水平的发酵豆粕替代鲫(Carassius auratus)饵料中的部分鱼粉对其生长性能的影响,并确定最佳的替代比例。试验选择体重相近、健康的体重在30.45g~30.55g的1龄鲫400尾按照单因素试验设计原则,将其均分为4个处理组,每组100尾鲫。分别使用发酵豆粕替代鲫饵料中的0%(试验1组,即对照组)、25%(试验2组)、50%(试验3组)、75%的鱼粉(试验4组)。试验周期为8周。试验结束,检测各组鲫的生长性能指标。结果表明,试验3组鲫的试验末重、增重率及特定生长率均显著高于试验1组、试验2组和试验4组(P<0.05),而各组间鲫的饵料系数和成活率均未产生显著性的影响(P>0.05)。结果表明,鲫在养殖生产中使用发酵豆粕替代饵料50%的鱼粉可以显著提高鲫的生长性能。
This experiment was conducted to investigate the effects of different levels of fermented soybean meal on the growth performance of Carassius auratus diet by replacing part of the fish meal with different levels of fermented soybean meal,and to determine the optimal replacement ratio.The first instar with similar body weight and healthy body weight between 30.45g and 30.55g were selected.Four hundred Carassius auratus were divided into four treatment groups according to the principle of single factor experimental design,with 100 Carassius auratus in each group.Fermented soybean meal was used to replace 0%(test group 1,control group),25%(test group 2),50%(test group 3)and 75%(test group 4)of fish meal in Carassius auratus diet,respectively.The trial period was 8 weeks.At the end of the experiment,the growth performance indexes of Carassius auratus were detected.The results showed that the final weight,weight gain rate and specific growth rate of Carassius auratus in trial group 3 were significantly higher than those in trial group 1,trial group 2 and trial group 4(P<0.05),and there was no significant effect on the feed coefficient and survival rate of crucian carp(P>0.05).The results showed that the replacement of 50%fish meal by fermented soybean meal could significantly improve the growth performance of Carassius auratus.
