Abstract

The experiment aimed to investigate the effects of dietary supplementation with Bacillus subtilis QST 713 (BS) on the reproductive performance, perinatal constipation, and offspring growth performance of sows. 78 multiparous Landrace-Yorkshire sows with same parity and backfat thickness were divided into 2 groups: a basal diet group (CON) and a basal diet supplemented with 1.5 × 10⁹ CFU/kg BS. The experiment was conducted from day 85 of gestation to day 21 of lactation. Reproductive performance, lactation performance, and perinatal fecal scores of sows were recorded. Samples were collected for subsequent analysis, including the feces of sows on day 110 of gestation, colostrum within 2 hours of parturition, milk on day 21 of lactation and feces from sows on day 21 of lactation. The results showed that, compared with the CON group, the BS group significantly shortened the duration of parturition (P < 0.01) and the average birth interval of piglets (P < 0.05), reduced stillbirth rate (P < 0.05) and invalid piglet rate (P < 0.05). Additionally, the BS group increased the content of protein (P < 0.05) and level of IgM in colostrum (P < 0.05), as well as the average daily gain (P < 0.05) of weaned piglets. The BS group increased the perinatal fecal score (P < 0.05) of sows, decreased the incidence of post-partum constipation (P < 0.05), and increased the relative abundance of Lactobacillus (P < 0.05) in feces on day 110 of gestation. In summary, a maternal diet supplemented with BS reduced the stillbirth rate by shortening the duration of parturition, alleviated perinatal constipation, and improved intestinal microbiota, meanwhile improving the growth performance of piglets by increasing nutrients and immunoglobulins in colostrum.

饲粮中添加枯草芽孢杆菌QST 713对母猪便秘、繁殖性能和子代生长性能的影响

本试验旨在研究饲粮中添加枯草芽孢杆菌QST 713 （BS）对母猪繁殖性能、围产期便秘及子代生长性能的影响。试验选用胎次和背膘厚相同的多胎长约克大母猪78头，分为基础饲粮组（CON）和基础饲粮中添加1.5 × 109 CFU/kg BS的组。试验时间为妊娠第85天至泌乳第21天。记录母猪的繁殖性能、泌乳性能和围产期粪便评分。收集母猪妊娠第110天的粪便、分娩后2 小时内的初乳、泌乳第21天的乳汁和泌乳第21天的粪便进行后续分析。结果表明，与CON组相比，BS组显著缩短了仔猪的分娩时间（P <； 0.01）和平均产仔间隔（P <； 0.05），降低了死产率（P <； 0.05）和无效仔猪率（P <； 0.05）。此外，BS组提高了断奶仔猪初乳蛋白质含量（P <； 0.05）和IgM水平（P <； 0.05），提高了断奶仔猪平均日增重（P <； 0.05）。BS组提高了母猪围产期粪便评分（P <； 0.05），降低了产后便秘发生率（P <； 0.05），提高了妊娠第110天粪便中乳酸杆菌的相对丰度（P <； 0.05）。综上所述，饲粮中添加BS可通过缩短分娩时间降低死产率，缓解围产期便秘，改善肠道菌群，同时通过增加初乳营养物质和免疫球蛋白提高仔猪生长性能。

期刊介绍： Animal Reproduction Science publishes results from studies relating to reproduction and fertility in animals. This includes both fundamental research and applied studies, including management practices that increase our understanding of the biology and manipulation of reproduction. Manuscripts should go into depth in the mechanisms involved in the research reported, rather than a give a mere description of findings. The focus is on animals that are useful to humans including food- and fibre-producing; companion/recreational; captive; and endangered species including zoo animals, but excluding laboratory animals unless the results of the study provide new information that impacts the basic understanding of the biology or manipulation of reproduction. The journal''s scope includes the study of reproductive physiology and endocrinology, reproductive cycles, natural and artificial control of reproduction, preservation and use of gametes and embryos, pregnancy and parturition, infertility and sterility, diagnostic and therapeutic techniques. The Editorial Board of Animal Reproduction Science has decided not to publish papers in which there is an exclusive examination of the in vitro development of oocytes and embryos; however, there will be consideration of papers that include in vitro studies where the source of the oocytes and/or development of the embryos beyond the blastocyst stage is part of the experimental design.
