摘  要：
分别用大豆浓缩蛋白(SPC)替代饲料中0(R0,对照组),15%(R15),30%(R30)和45%(R45)的鱼粉蛋白,配制成4组等氮等能饲料,喂养(58.00±2.69)g中华鲟(Acipenser sinensis)幼鱼10周,每组设3个重复,研究SPC对中华鲟幼鱼生长性能、饲料利用率,以及血脂和体成分的影响。结果显示,随替代比例的增加,中华鲟幼鱼的增重率(WG)、特定生长率(SGR)、饲料效率(FE)和蛋白质效率(PER)逐渐降低,肥满度和肝体指数无显著性差异(P>0.05)。FE在R30组出现显著差异(P<0.05),WG、SGR和PER在R45组出现显著性差异(P<0.05)。随替代比例的增加,血浆高密度脂蛋白胆固醇含量无显著变化(P>0.05),胆固醇(CHOL)、甘油三脂(TG)和低密度脂蛋白胆固醇(LDL-C)含量逐渐降低。CHOL、TG和LDL-C含量在R30组出现显著差异(P<0.05)。随替代比例的增加,肌肉和肝脏水分逐渐升高,脂肪逐渐降低,蛋白含量无显著差异(P>0.05)。R30和R45组的肌肉和肝脏水分含量显著高于R0组(P<0.05),脂肪含量显著低于R0组(P<0.05)。结果表明:在本试验条件下,综合考虑生长性能、饲料利用、血脂和体成分等指标,中华鲟幼鱼饲料中SPC替代鱼粉蛋白的比例可达30%。

摘  要：
Juvenile Chinese sturgeon(Acipenser sinensis)(58.00±2.69 g) were fed four isonitrogenous and isocaloric diets which contained four levels of soy protein concentration(SPC) to replace fish meal protein [0(R0,control group),15%(R15),30%(R30) and 45%(R45)] for 10 weeks,to investigate the effects of SPC on growth performance,feed utilization,hematology and carcass composition.With the increase of SPC ratio in diets,weight gain(WG),specific growth rate(SGR),feed efficiency(FE) and protein efficiency ratio(PER) decreased,but condition factor(CF) and hepatosomatic index(HSI) had no significant difference.FE presented statistical significance in R30,WG,SGR and PER showed statistical significance in R45.There was no significant difference in plasma high density lipoprotein cholesterol content,but plasma cholesterol(CHOL),triglyceride(TG),and low density lipoprotein cholesterol(LDL-C) decreased as SPC ratio increased.CHOL,TG and LDL-C presented statistical significance in R30.In muscle and liver,with the increasing SPC ratio in diets,moisture content increased,but fat content reversed,and protein content had no significant difference.Muscle and liver moisture content of R30 and R45 groups were significantly higher than R0,while fat content were significantly lower than R0.Based on the results of growth performance,feed utilization,plasma lipids and carcass composition,the replacement level of SPC for fish meal protein could be up to 30%.
