摘　　要：试验旨在探究大豆膳食纤维(Soybean dietary fibers,SDFs)对草鱼免疫功能及肉质的影响。试验将体质均匀的800尾体重(301.58±3.89)g的健康草鱼随机分到40个2.0 m×1.8 m×1.6 m的网箱(重复)中,每个重复20尾,每10个网箱为1组,各组(试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组)分别饲喂添加0%、0.6%、1.2%和2.4%SDF的试验饲日粮,试验为期60 d。结果表明,与Ⅰ和Ⅱ组相比,Ⅲ、Ⅳ组血清碱性磷酸酶(AKP)含量显著上调(P<0.05),Ⅲ组酸性磷酸酶(ACP)含量显著上调(P<0.05),Ⅳ组溶菌酶(LZM)含量显著上调(P<0.05);与Ⅰ和Ⅱ组相比,前肠Ⅲ和Ⅳ组AKP和LZM含量显著上调(P<0.05);中肠Ⅲ和Ⅳ组ACP含量显著上调(P<0.05),Ⅱ~Ⅳ组AKP和C3含量显著上调(P<0.05);后肠Ⅳ组LZM含量显著上调(P<0.05);Ⅲ和Ⅳ组肌肉弹性显著提升(P<0.05),Ⅳ组肌肉黏性显著提高(P<0.05),Ⅲ和Ⅳ组肌肉蒸煮损失显著减少(P<0.05)。结论,添加2.4%的大豆膳食纤维能增强草鱼免疫力,改善其肉质。The purpose of the experiment is to explore the effects of soybean dietary fibers(SDFs)on the immune function and meat quality of grass carp.800 healthy grass carp(301.58±3.89 g)with uniform physique were randomly divided into 402.0×1.8×1.6 m net cages(replicates),with 20 fish per replicate and 10 net cages per group.Each group(experimental groupsⅠ,Ⅱ,Ⅲ,Ⅳ)was fed with experimental feed supplemented with 0%,0.6%,1.2%,and 2.4%SDF,respectively,for a total of 60 days.Compared with groupsⅠandⅡ,the serum alkaline phosphatase(AKP)content was significantly upregulated in groupsⅢandⅣ(P<0.05),the acid phosphatase(ACP)content was significantly upregulated in groupⅢ(P<0.05),and the lysozyme(LZM)content was significantly upregulated in groupⅣ(P<0.05);Compared with groupsⅠandⅡ,the AKP and LZM contents in the foregut of groupsⅢandⅣwere significantly upregulated(P<0.05);The ACP content in midgut groupsⅢandⅣwas effectively upregulated(P<0.05),while the AKP and C3 content were effectively upregulated in groupsⅡ-Ⅳ(P<0.05);The LZM content in the hindgutⅣgroup was effectively upregulated(P<0.05);The muscle elasticity of groupsⅢandⅣwas effectively improved(P<0.05),the muscle viscosity of groupⅣwas effectively improved(P<0.05),and the muscle steaming loss was effectively reduced in groupsⅢandⅣ(P<0.05).(Conclusion)Adding 2.4%soybean dietary fiber can enhance the immunity of grass carp and improve their meat quality.
