摘要: 【目的】探究饲喂蚯蚓对黄鳝生长性能、营养成分及非特异性免疫的影响,为黄鳝养殖中蚯蚓的应用提供参考。【方法】试验所用黄鳝分为C组、35组和S组,C组和35组饲喂人工配合饲料,并分别添加0和35%蚯蚓粉,S组饲喂鲜活蚯蚓,养殖60 d后取样测定生长指标、常规营养指标、氨基酸指标、脂肪酸指标和非特异性免疫指标。【结果】35组的黄鳝终末体重(45.21 g)、相对增重率(94.05%)、特定生长率(1.10%/d)最高,且显著高于S组和C组(P<0.05);肌肉中粗蛋白含量(19.29%)、粗灰分含量(0.76%)最高;氨基酸总量(76.50%)、必需氨基酸总量(26.85%)、非必需氨基酸总量(49.65%)、呈味氨基酸总量(36.62%)和必需氨基酸指数(99.61)较高。黄鳝肌肉脂肪酸指标中,S组的饱和脂肪酸含量(30.79%)最高,35组较高(28.85%);C组的不饱和脂肪酸含量(74.96%)最高。在非特异性免疫方面,35组的超氧化物歧化酶、过氧化氢酶活性最高,分别为321.21、1.35 U/mL;S组总抗氧化能力(7.65 U/mL)最高;3组间的过氧化氢酶、酚氧化酶和溶菌酶活性差异不显著(P>0.05)。【结论】在饲料中添加35%蚯蚓粉的养殖效果最佳,能够增强黄鳝的生长性能,提高其肌肉氨基酸营养水平和血清非特异性免疫水平,但会降低肌肉脂肪酸含量。

Abstract: 【Objective】 To investigate the effects of earthworm feeding on the growth performance,nutritional composition,and non-specific immunity of Monopterus albus,providing a reference for the application of earthworms in M. albus aquaculture.【Methods】 Experimental M. albus were divided into three groups:Group C,Group 35,and Group S. Group C and Group 35 were fed artificial formulated feed supplemented with 0 and 35% earthworm powder,respectively,while Group S was fed live earthworms. After a 60 d rearing period,samples were collected to measure growth indices,proximate nutritional indices,amino acid indices,fatty acid indices,and non-specific immune indices.【Results】 M. albus in Group 35 exhibited the highest final body weight(45.21 g),relative weight gain rate(94.05%),and specific growth rate(1.10%/d),all of which were significantly higher than those of Group S and Group C(P<0.05);the muscle crude protein content(19.29%) and crude ash content(0.76%) were the highest;the total amino acid content(76.50%),total essential amino acid content(26.85%),total non-essential amino acid content(49.65%),total flavor amino acid content(36.62%),and essential amino acid index(99.61) were relatively high. Regarding fatty acid indices of M. albus muscle,Group S showed the highest saturated fatty acid content(30.79%),followed by Group 35(28.85%),while Group C had the highest unsaturated fatty acid content(74.96%). For non-specific immunity,Group 35 showed the highest superoxide dismutase and catalase activities,reaching 321.21 and 1.35 U/mL,respectively;Group S recorded the highest total antioxidant capacity(7.65 U/mL);no significant differences were observed in catalase,phenoloxidase,and lysozyme activities among the three groups(P>0.05).【Conclusion】 Supplementation of 35% earthworm powder in the feed yields the best rearing results. It enhances the growth performance of M. albus,improves the nutritional level of muscle amino acids and serum non-specific immunity,but reduces muscle fatty acid content.
