枯草芽孢杆菌对围产期母猪粪便微生物及其代谢产物的影响
Effects of Bacillus subtilis on Fecal Microbes and Their Metabolites of Peripartum Sows
摘要
Abstract
This study was conducted to determine the effects of Bacillus subtilis on fecal microbes and their metabolites of peripartum sows.Forty healthy Large White sows at close to day 85 of pregnancy during 2 to 4 parities were used and randomly allocated to 2 groups with 20 pigs per group.The sows in the control group were fed a basal diet,and the others in the experimental group were fed the basal diet supplemented with 250 g/t Bacillus subtilis preparation.The trial period was from day 85 of pregnancy to day 21 of postpartum.Eight sows per group were randomly selected and the fresh feces were collected at days 100 and 112 of pregnancy and days 7,14 and 21 of postpartum,respectively,and the microbial population and the contents of short chain fatty acids (SCFA) and bioamines of feces were analyzed.The results showed as follows:compared with the control group,1) dietary Bacillus subtilis significantly increased the fecal Lactobacillus population and the ratio of Lactobacillus to Escherichia coli of sows at day 7 of postpartum and fecal Firmicutes population at day 21 of postpartum (P＜0.05).2) Dietary Bacillus subtilis significantly increased the contents of fecal acetate,isobutyrate,branched chain fatty acid and total SCFA of sows at day 100 of pregnancy (P＜0.05),the contents of fecal valerate,straight-chain fatty acids,isobutyrate,isovalerate,branched chain fatty acid and total SCFA at day 7 of postpartum (P＜0.05),and the contents of fecal propionate,butyrate and straight-chain fatty acids at day 21 of postpartum (P＜0.05).But dietary Bacillus subtilis significantly decreased the fecal isovalerate content of sows at day 14 of postpartum (P＜0.05).3) Dietary Bacillus subtilis significantly increased the fecal cadaverine content of sows at day 100 of pregnancy (P＜0.05),the contents of fecal spermidine and spermine at day 112 of pregnancy (P＜0.05),and the contents of fecal cadaverine,tyramine,spermidine and spermine at day 14 of postpartum (P＜0.05).Collectively,dietary Bacillus subtilis can increase the intestinal beneficial microbes population and contents of several bioamines and SCFA of perinatal sows,which plays important roles in improving intestinal health and nutritional status of sows.关键词
