浒苔粉对圆斑星鲽生长、体成分、消化酶活性及血清生化指标的影响OA北大核心CSTPCD
Effects of Enteromorpha prolifera powder on growth,body composition,digestive enzymes activity,and serum biochemical indicators of Verasper variegatus
试验旨在探究不同比例浒苔粉对圆斑星鲽生长、体成分、消化酶活性及血清生化指标的影响.选取(87±1)g同一批的圆斑星鲽300尾,随机分为5组,每组3个重复,每个重复20尾.各组浒苔粉的添加量分别为0(A组)、4％(B组)、8％(C组)、12％(D组)、16％(E组).试验期10周.结果显示,B组圆斑星鲽的饲料效率显著高于C组、D组、E组(P＜0.05),增重率显著高于其他各组(P＜0.05).B组圆斑星鲽肥满度显著高于C组、D组和E组(P＜0.05),肝体比显著高于E组(P＜0.05).B组圆斑星鲽的粗蛋白含量显著高于D组和E组(P＜0.05).B组圆斑星鲽的肠蛋白酶活性显著高于A组、D组和E组(P＜0.05),脂肪酶活性显著高于C组、D组和E组(P＜0.05).B组圆斑星鲽的血清总蛋白含量显著高于C组、D组和E组(P＜0.05),B组圆斑星鲽的血清甘油三酯含量显著低于D组和E组(P＜0.05).研究表明,饲料中添加4％的浒苔粉能够提高圆斑星鲽的生长性能,改善体成分,提高消化酶活性,调节血清生化指标.
The experiment was to study the effects of different proportions of Enteromorpha prolifera powder on growth,body composition,digestive enzyme activity,and serum biochemical indicators of Verasper variegatus.A total of 300 Verasper variegatus of the same batch and weight(87±1)g were randomly divided into five groups with three replicates in each group and 20 fish in each replicate.The addition amounts of Enteromorpha prolifera powder in each group were 0(Group A),4％(Group B),8％(Group C),12％(Group D),and 16％(Group E),respectively.The test period was 10 weeks.The results showed that the feed efficiency of Group B was significantly higher than that of Group C,Group D,and Group E(P＜0.05),and the weight gain rate was significantly higher than other groups(P＜0.05).The condition factor of Group B was significantly higher than that of Group C,Group D,and Group E(P＜0.05),and the liver-body ratio was significantly higher than that of Group E(P＜0.05).The crude protein content of Group B was significantly higher than that of Group D and Group E(P＜0.05).The intestinal protease activity of Group B was significantly higher than that of Group A,Group D,and Group E(P＜0.05),and the intestinal lipase activity was significantly higher than that of Group C,Group D,and Group E(P＜0.05).The total serum protein content of Group B was significantly higher than that of Group C,Group D,and Group E(P＜0.05),while the serum triglyceride content of Group B was significantly lower than that of Group D and Group E(P＜0.05).The study indicates that 4％Enteromorpha prolifera powder in the diet can improve the growth performance,body composition,digestive enzyme activity,and serum biochemical indicators.
