【摘要】：为了探讨中药渣在妊娠母猪饲粮中添加的可行性,试验选用2~4胎次、预产期相近的二元妊娠母猪60头,随机分为对照组、中药渣组和发酵中药渣组,比较研究发酵前和发酵后中药渣对母猪粪便微生物及其代谢产物的影响。结果表明:与对照组相比,中药渣组和发酵中药渣组母猪产前粪便中乙酸、丙酸、丁酸、直链脂肪酸和总短链脂肪酸含量均显著增加(P0.05),支链/直链脂肪酸比值显著降低(P0.05);中药渣组母猪产前粪便中苯乙胺和产后色胺含量均显著降低(P0.05);发酵中药渣组母猪产后粪便中亚精胺、精胺和乳酸菌含量均显著增加(P0.05),大肠杆菌含量显著降低(P0.05)。由此可见,饲粮添加发酵中药渣可改善妊娠母猪肠道微生物菌群平衡、增加短链脂肪酸含量,从而有利于妊娠母猪繁殖性能的提高。
[Abstract]:In order to explore the feasibility of adding traditional Chinese medicine residue into the diet of pregnant sows, 60 pregnant sows with 2 carps of 4 births and similar expected dates were randomly divided into three groups: control group, traditional Chinese medicine residue group and fermentative Chinese medicine residue group. The effects of traditional Chinese medicine residue on fecal microorganism and metabolites of sows before and after fermentation were compared. The results showed that acetic acid, propionic acid, butyric acid in feces of sows in traditional Chinese medicine residue group and fermentative Chinese medicine residue group were higher than those in control group. The content of straight chain fatty acid and total short chain fatty acid increased significantly, the ratio of branched chain to straight chain fatty acid decreased significantly, the content of phenylethylamine and postpartum tryptamine in feces of sows in traditional Chinese medicine group decreased significantly, and the content of phenylethylamine and postpartum tryptamine in sows in fermentative residue group decreased significantly. Spermidine in postpartum feces, The contents of spermine and lactic acid bacteria increased significantly, while the content of Escherichia coli decreased significantly. It can be seen that the addition of residue in diet can improve the balance of microbial flora and increase the content of short chain fatty acids in the intestine of pregnant sows, which is beneficial to the improvement of reproductive performance of pregnant sows.
