摘　　要：研究旨在探讨饲粮中同时添加益生菌和复合维生素对丹系母猪繁殖性能、初乳成分、血浆免疫及生化指标的影响。试验选取3胎次且预产期相近的产前(30±3)d的丹系大白母猪80头,随机分为4组,每组4个重复,每个重复5头母猪。对照组饲喂基础饲粮,A组、B组和C组分别在基础饲粮中添加0.10%益生菌+0.02%复合维生素、0.15%益生菌+0.02%复合维生素、0.20%益生菌+0.02%复合维生素。试验期60 d。结果显示,与对照组相比,B组和C组母猪的哺乳期背膘损失显著增加(P<0.05),A组和B组的仔猪断奶窝重显著升高(P<0.05);B组仔猪的断奶日龄显著低于其他组(P<0.05),30日龄断奶成活率显著高于其他组(P<0.05),每窝断奶仔猪数显著高于对照组和C组(P<0.05)。B组和C组母猪的初乳中乳脂、乳蛋白含量均显著高于对照组(P<0.05)。在产前第15天、分娩后第14天,B组和C组母猪血浆中总蛋白(TP)、白蛋白(ALB)、免疫球蛋白G(IgG)含量显著高于对照组(P<0.05),白细胞介素-6(IL-6)含量显著低于对照组(P<0.05);B组血浆中谷丙转氨酶(ALT)活性显著高于其他组(P<0.05),免疫球蛋白M(IgM)含量显著高于对照组(P<0.05),试验组血浆中肿瘤坏死因子-α(TNF-α)含量显著低于对照组(P<0.05)。在产前第15天,B组母猪血浆中谷草转氨酶(AST)活性显著高于A组和对照组(P<0.05)。在分娩后第14天,B组和C组母猪血浆中免疫球蛋白A(IgA)含量显著高于其他组(P<0.05),白细胞介素-2(IL-2)含量显著低于对照组(P<0.05)。研究表明,在饲粮中添加益生菌和复合维生素能够提高丹系母猪的繁殖性能,改善初乳成分,增强母猪免疫功能,且以B组(添加0.15%益生菌+0.02%复合维生素)效果较好。The study aimed to investigate the effects of dietary supplementation with probiotics and multivitamins on the reproductive performance,colostrum composition,plasma immune,and biochemical indices of Danish sows.A total of 80 Danish big white sows(30±3)days before delivery with three parity and similar expected date were selected and randomly divided into four groups,with four replicates per group and five sows per replicate.The control group was fed a basal diet,while groups A,B,and C were supplemented with 0.10%probiotics+0.02%multivitamins,0.15%probiotics+0.02%multivitamins,and 0.20%probiotics+0.02%multivitamins,respectively.The trial lasted for 60 days.The results showed that compared to the control group,backfat loss during lactation was significantly increased in groups B and C(P<0.05),while the weaning litter weight was significantly higher in groups A and B(P<0.05).The weaning age of piglets in group B was significantly lower than in other groups(P<0.05),and the 30-day weaning survival rate was significantly higher than in other groups(P<0.05).The number of weaned piglets per litter in group B was significantly higher than in the control and group C(P<0.05).The colostrum fat and protein concentrations in groups B and C were significantly higher than in the control group(P<0.05).On day 15 pre-farrowing and day 14 post-farrowing,the plasma concentrations of total protein(TP),albumin(ALB),and immunoglobulin G(IgG)in groups B and C were significantly higher than in the control group(P<0.05),while interleukin-6(IL-6)content were significantly lower than in the control group(P<0.05).Plasma alanine aminotransferase(ALT)activity in group B was significantly higher than in other groups(P<0.05),and immunoglobulin M(IgM)content was significantly higher than in the control group(P<0.05).Plasma tumor necrosis factor-α(TNF-α)content in the experimental groups was significantly lower than in the control group(P<0.05).On day 15 pre-farrowing,plasma aspartate aminotransferase(AST)activity in group B was significantly hi
