摘要
为了验证饲料中添加发酵豆粕特酵001(以下简称发酵豆粕)对加州鲈生长性能的影响,以体重为14 g左右的加州鲈鱼苗为研究对象,以循环水的方式饲养加州鲈鱼苗,试验分为6组,分别在饲料中添加0%、5%、7.5%、10%、12.5%、15%的发酵豆粕,通过6周的试验观察并分析不同添加量发酵豆粕对加州鲈生长、饲料利用效率的影响。试验结果表明,在基础配方饲料中添加5%发酵豆粕,加州鲈的增重率、特定成长率显著高于对照组(P<0.05),5%发酵豆粕添加量组和对照组饲料系数显著优于12.5%和15%发酵豆粕添加量组(P<0.05),7.5%发酵豆粕添加量组饲料系数显著优于15%添加量组(P<0.05),各组间粪便溃散度差异不显著(P>0.05)。本试验结果显示,在基础饲料中添加5%或7.5%发酵豆粕可提高加州鲈的生长性能和饲料利用率,但随着发酵豆粕添加量增加,加州鲈鱼生长性能指标及饲料利用率有所降低。
This study aimed to investigated the effects of dietary supplementation with fermented soybean meal Tejiao 001(fermented soybean meal)on the growth performance of California perch.California perch fry with the body weight of about 14 g were taken as the research object and fed with circulating water.The experiment was divided into6 groups.The diets were supplemented with 0%,5%,7.5%,10%,12.5%,and 15%fermented soybean meal,respectively,this study lasted for 6 weeks.The results showed that dietary supplementation with 5%fermented soybean meal significantly increased the weight gain rate(WGR)and specific growth rate(SGR)of California perch(P<0.05),and feed conversion ratio(FCR)of 5%fermented soybean meal group and control group were significantly better than those of 12.5%and 15%fermented soybean meal groups(P<0.05).The feed conversion ratio in 7.5%fermented soybean meal group was significantly better than that in 15%fermented soybean meal group(P<0.05),while there was no significant difference in fecal breakdown among all groups(P>0.05).The results showed that the basal diet supplemented with 5%or 7.5%fermented soybean meal could improve the growth performance and feed efficiency of California perch,but with the increase of fermented soybean meal,the growth performance indexes and feed efficiency of California perch decreased.
