摘　　要：用不添加蝇蛆粉的对照饲料和添加1.0%、1.8%、2.6%、3.4%、4.2%、5.0%蝇蛆粉的6种试验饲料，分别饲喂初重为 （127.424.83）g的青鱼8周，研究蝇蛆粉对青鱼生长、体成分和消化酶活力的影响。试验结果表明：摄食添加5.0%蝇蛆粉组青鱼终末体重和特定生长率最高，饲料系数最低；饲料中添加蝇蛆粉可降低青鱼肝体比和脏体比，当添加量为5.0%时降至最低且与对照组差异显著（P〈0.05）。摄食添加4.2%蝇蛆粉组，青鱼全鱼粗蛋白含量达到最大值，与对照组和蝇蛆粉添加量为1.0%、1.8%组差异显著（P〈0.05），添加量为3.4%、4.2%、5.0%组鱼体肌肉中的粗蛋白含量较对照组显著升高（P〈0.05）。摄食添加4.2%蝇蛆粉的试验饲料后，青鱼肠道和肝胰脏蛋白酶活力以及肠道淀粉酶活力均达到最大值且与对照组差异显著（P〈0.05），摄食5.0%蝇蛆粉组其肠道和肝胰脏脂肪酶活力达到最大值与对照差异显著（P〈0.05）。因此，在试验条件下，饲料中添加4.2%～5.0%的蝇蛆粉能促进青鱼的生长、提高青鱼肠道和肝胰脏消化酶活力，提高全鱼蛋白含量改善肌肉品质。A basal diet without adding maggot meal（MGM） and six test diets containing 1.0%, 1.8%, 2.6%, 3.4%, 4.2%, 5.0% of the MGM were prepared to feed seven groups of black carp（Mylopharyngodon piceus） in triplicate with an initial average body weight of （127.424.83） g respectively for eight weeks. The results showed the Black carp fed the diet containing 5.0% MGM had higher final body weight（FBW）, body weight gain（BWG）, specific growth rate（SGR） and lower feed conversion ratio（FCR） than the others. The HIS and VSI decreased significantly when adding 5.0% MGM compared with control group （P〈0.05）. Body composition analysis showed that whole crude protein content increased significantly with the increasing of MGM levels（P〈0.05）. Compared with the control group, the crude protein content of fishes muscle increased significantly when adding 3.4%, 4.2%, 5.0% MGM（P〈0.05）. Intestine and hepatopancreas protease, intestine amylase activities of fish fed diet with 4.2% MGM were higher than those of fish fed the basal diet （P〈0.05）, hepatopancreas and intestine lipase activity increased with the increasing level of MGM supplement up to 5.0%. In conclusion, under the condition of this experiment, adding 4.2%-5.0% MGM to black carp diet could improve fish growth, digestive enzymes activities, whole fish crude protein content and muscle quality.
