富乐旺(Flavomycin)对黄河鲤鱼消化酶活性的影响

研究了饲料中添加不同水平富乐旺(2mg/kg、4mg/kg、6mg/kg和8mg/kg)对黄河鲤鱼生长性能和消化酶活性的影响。结果表明:试验组黄河鲤鱼的生物学综合评价高于对照组,其中添加6mg/kg富乐旺的试验组淇河鲫鱼的生物学综合评价最好(119);饲料系数4mg/kg和6mg/kg富乐旺添加组显著高于对照组(P<0.05);4mg/kg富乐旺添加组胰蛋白酶活性著高于对照组和8mg/kg富乐旺添加组(P<0.05);4mg/kg、6mg/kg富乐旺添加组肠蛋白酶活性显著高于对照组(P<0.05);2mg/kg、4mg/kg、6mg/kg富乐旺添加组胰淀粉酶活性显著高于对照组(P<0.05),4mg/kg富乐旺添加组肠淀粉酶活性显著高于对照组(P<0.05);6mg/kg富乐旺添加组胰脂肪酶和肠脂肪酶酶活性与对照组相比,差异显著(P<0.05)。

Effects of Flavomycin on Activities of Digestive Enzymes in Cyprinus Carpio

An experiment was conducted to investigate the effects of different levels of Flavomycin supplement on growth performance and activities of digestive enzymes in Cyprinus carpio. The results showed: The biology synthesis evaluates in the groups fed diets with Flayomycin were higher and that (119) in the group fed diets with 6mg/kg Flayomycin was the highest. Feed coefficients in the groups fed diets with 4mg/kg and 6mg/kg Flayomycin were significantly higher than that in the control group (P<0.05). The activities of trypsin and intestinal protease were the highest in the group fed diets with 4mg/kg Flayomycin. The activities of trypsin in the group fed diets with 4mg/kg Flayomycin were significantly higher than those in the control group and the group fed diets with 8mg/kg Flayomycin (P<0.05). The activities of intestinal protease in the group fed diets with 4mg/kg and 6mg/kg Flayomycin were significantly higher than those in the control group (P<0.05). The amylase activities in hepatopancreas in the groups fed diets with 2mg/kg, 4mg/kg, 6mg/kg Flayomycin were significantly higher than those in the control group (P<0.05). The amylase activities in intestine in the group fed diets with 4mg/kg Flayomycin were significantly higher than those in the control group (P<0.05). The lipase activities in hepatopancreas and intestine in the group fed diets with 6mg/kg Flayomycin were significantly higher than those in the control group (P<0.05).
