【摘要】：试验旨在研究妊娠后期母猪日粮中添加低聚木糖和益生菌对母猪繁殖性能及哺乳仔猪生长性能的影响。试验采用随机区组试验设计,选取妊娠108 d的母猪(体重及预产期相近,长白×大白)48头,随机分为3个处理,每个处理16个重复,每个重复1头母猪。对照组饲喂基础日粮,试验组分别在基础日粮中添加0.05%XOS(试验1组)和0.05%XOS+0.03%益生菌(试验2组),试验期35 d。结果表明:(1)3个处理母猪哺乳期平均日采食量(ADFI)、产仔总数、活产仔数、合格仔数、初生均重和母猪7 d发情率等几方面差异均不显著(P0.05)。所有胎次母猪的发情间隔、背膘损失和产程差异均不显著(P0.05)。但3~6胎次母猪试验1组的发情间隔显著低于对照组(P0.05),试验2组母猪背膘损失极显著低于对照组(P0.01);(2)从所有胎次母猪和3~6胎母猪所产仔猪来看,3个试验组仔猪的哺乳期ADG差异不显著(P0.05)。但从3~6胎以外母猪所产仔猪来看,试验2组的哺乳期ADG比对照组高34.36%(P0.01),试验1组哺乳期ADG比对照组高21.47%(P0.05)。(3)3个试验组仔猪断奶成活率没有显著差异(P0.05)。由此可见,在妊娠后期母猪日粮中单独添加低聚木糖或者同时添加低聚木糖和益生菌对母猪产程和发情间隔没有明显的改善作用,同时添加低聚木糖和益生菌极显著降低3~6胎母猪的背膘损失。仔猪断奶成活率与母猪胎次以及低聚木糖和益生菌的添加水平有关。母源性低聚木糖和益生菌对哺乳仔猪生长性能没有明显促进作用。
[Abstract]:The aim of the experiment was to study the effects of xylooligosaccharide and probiotics on reproductive performance and growth performance of lactating piglets in the later pregnant sows. A randomized block design was used to select 48 sows of 108 days gestation (with similar body weight and expected period of birth), which were randomly divided into 3 treatments, 16 replicates each, and one sows per replica. The control group was fed with basal diet and the experimental group was fed with 0.05%XOS (test group 1) and 0.05%XOS 0.03% probiotics (group 2) for 35 days. The results showed that: (1) there were no significant differences in the average daily feed intake (ADFI), the number of live litter, the number of eligible litter, the average weight of initial birth and the estrus rate of 7 days in the three treatments (P0.05). There was no significant difference in estrus interval, backfat loss and labor process among all the second sows (P0.05). However, the estrus interval of trial 1 was significantly lower than that of control group (P0.05). The backfat loss of sows in test 2 was significantly lower than that in control group (P0.01); (2). There was no significant difference in ADG (P0.05). But according to the piglets produced from the sows other than 3 flocks, the ADG of the second group was 34.36% higher than that of the control group (P0.01), and the ADG of the first group was 21.47% higher than that of the control group (P0.05). (3). There was no significant difference in weaning survival rate among the three groups (P0.05). It can be seen that adding xylooligosaccharides alone or adding both xylooligosaccharides and probiotics to the diet of sows in late pregnancy did not significantly improve the birth process and estrus interval of sows. At the same time, the addition of xylooligosaccharides and probiotics significantly reduced the backfat loss of 3 / 6 sows. The survival rate of weaning piglets was related to the birth order of sows and the addition level of xylooligosaccharides and probiotics. Maternal xylooligosaccharides and probiotics did not promote the growth performance of suckling piglets.
