摘  要：
本试验旨在研究用切达奶酪粉(cheddar cheese by-products,CCB)部分替代鱼粉对虹鳟(Oncorhynchus mykiss)幼鱼生长性能、体成分和血浆生化指标的影响。用切达奶酪粉分别替代基础饲料中0、15%、30%和45%的鱼粉蛋白质,同时逐渐降低豆油使用量,配成4个等氮等能的试验饲料,并分别命名为C0、C15、C30、C45。选用初均重为(5.73±0.00)g的虹鳟幼鱼640尾,随机分为4组,每组设4个重复,每个重复40尾,在循环水养殖系统中养殖8周。结果表明,C15、C30组虹鳟幼鱼的各项生长指标与对照组(C0组)相比均没有显著差异(P>0.05),而C45组虹鳟幼鱼的日摄食量、增重率、特定生长率显著低于对照组(P<0.05)。C15、C30组虹鳟幼鱼的肥满度、肝体比、脏体比、体成分较对照组差异不显著(P>0.05),而C45组虹鳟幼鱼的鱼体灰分含量显著高于对照组(P>0.05)。C30组虹鳟幼鱼的各项血浆生化指标与对照组相比均没有显著差异(P>0.05)。根据本试验结果,切达奶酪粉可以在虹鳟幼鱼饲料中替代30%的鱼粉蛋白质(9.6%鱼粉,同时使豆油的添加量由5%降至3%)而不显著影响其生长性能、体成分和血浆生化指标。

摘  要：
An 8-week growth trial was conducted to evaluate the effects of a partial replacement of fish meal by cheddar cheese by-products(CCB) on growth performance,body composition and plasma biochemical indices of juvenile rainbow trout(Oncorhynchus mykiss).Four isonitrogenous and isoenergetic diets were prepared with CCB to replace 0,15%,30% and 45% of protein supplied by fish meal and meanwhile the soybean oil was gradually decreased,and were named as C0,C15,C30 and C45,respectively.Forty juvenile rainbow trout with initial average body weight of(5.73±0.00) g were randomly assigned to each tank with 4 replicates for each treatment in recirculation system.The results showed as follows: compared with control group(C0 group),all growth indices of juvenile rainbow trout in C15 and C30 groups were not significantly different(P>0.05),while dairy feed intake(AFI),weight gain rate(WGR) and specific growth rate(SGR) of juvenile rainbow trout in C45 group were significantly decreased(P<0.05).Condition factor(CF),viscerasomatic index(VSI),hepaticsomatic index(HSI) and body composition of juvenile rainbow trout in C15 and C30 groups were not significantly different compared with control group(P>0.05),however,the body ash content of juvenile rainbow trout was significantly higher than that in control group(P<0.05).No significant differences were observed in plasma biochemical indices between control group and C30 group(P>0.05).In conclusion,CCB can replace 30% fish meal protein(9.6% of fish meal,and the soybean oil supplementation from 5% to 3%,concurrently) in juvenile rainbow trout diets with no significant effects on growth performance,body composition and plasma biochemical indices.
