【摘要】：【目的】本试验旨在研究发酵菜籽粕对生长猪生长性能、机体抗氧化和免疫功能的影响。【方法】选用健康、体重相近的杜×长×大三元杂交生长猪64头,随机分成4组,每组4个重复,每重复4头猪。对照组饲喂玉米-豆粕型基础日粮,试验1、2、3组分别饲喂在基础日粮中添加发酵菜籽粕等氮替代2.5%、5%、7.5%豆粕的试验日粮。预试期7 d,正试期31 d。【结果】(1)试验各组平均日增重(ADG)和平均日采食量(ADFI)均高于对照组,试验3组ADG、ADFI和试验2组ADFI均显著高于对照组(P0.05),各组生长猪料重比(F/G)无显著差异(P0.05),试验3组F/G最低,较对照组低6.07%(P0.05)。(2)试验3组血清超氧化物歧化酶(SOD)活性和总抗氧化能力(T-AOC)含量显著高于对照组(P0.05),丙二醛(MDA)含量显著低于对照组(P0.05)。各组血清谷胱甘肽过氧化物酶(GSH-Px)和过氧化氢酶(CAT)活性均无显著差异(P0.05)。(3)试验3组血清免疫球蛋白A(Ig A)、免疫球蛋白G(Ig G)和白细胞介素2(IL-2)含量显著高于对照组(P0.05)。各组血清免疫球蛋白M(Ig M)、白细胞介素1(IL-1)、白细胞介素6(IL-6)和肿瘤坏死因子-α(TNF-α)含量均无显著差异(P0.05)。【结论】综上所述,在本试验条件下,发酵菜籽粕可提高生长猪生长性能,改善机体的抗氧化与免疫功能,且等氮替代7.5%豆粕效果显著。
[Abstract]:[objective] to study the effects of fermented rapeseed meal on growth performance, antioxidation and immune function of growing pigs. [methods] 64 healthy, similar weight DU 脳 long 脳 large hybrid pigs were randomly divided into 4 groups. There were 4 replicates in each group and 4 pigs in each group. The control group was fed with corn-soybean meal basal diet, and the experimental diet with fermentation rapeseed meal was added to the basal diet to substitute 2.5% and 7.5% soybean meal. [results] [results] (1) the average daily gain (ADG) and average daily intake (ADFI) of the three groups were higher than those of the control group, the ADG,ADFI of the three groups and the ADFI of the second group were significantly higher than that of the control group (P0.05). There was no significant difference in feed weight ratio (F / G) among the three groups (P0.05). The levels of serum superoxide dismutase (SOD) activity and total antioxidant capacity (T-AOC) in the three groups were significantly higher than those in the control group (P0.05). The content of malondialdehyde (MDA) was significantly lower than that of control group (P0.05). There was no significant difference in the activities of serum glutathione peroxidase (GSH-Px) and catalase (CAT) among the three groups (P0.05). (3). The levels of immunoglobulin G (Ig G) and interleukin 2 (IL-2) were significantly higher than those in the control group (P 0.05). The levels of serum immunoglobulin M (Ig M), interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor- 伪 (TNF- 伪) were not significantly different among the three groups (P0.05). [conclusion] Under the experimental conditions, fermented rapeseed meal could improve the growth performance of growing pigs, improve the body's antioxidant and immune function, and the effect of isonitrogen replacing 7.5% soybean meal was remarkable.
