本试验旨在比较中药渣和发酵中药渣对母猪粪便微生物及其代谢产物的影响,为其在母猪饲粮中的应用提供依据。试验选用2 ~ 4胎次、预产期相近的二元母猪60头,随机分为3组,每组20头。3组分别在基础饲粮中添加2 kg / t的米糠(对照组) 、2 kg / t的中药渣和2 kg / t的发酵中药渣。从妊娠85 d开始饲喂,到产后21 d结束。分别于妊娠110 d和产后21 d,每组随机收集8头母猪的新鲜粪便样品,测定微生物数量以及短链脂肪酸(SCFA)和生物胺的含量。结果表明:与对照组相比,中药渣组母猪产前粪便中丙酸含量显著增加(P < 0.05),丁酸(P = 0.086) 、直链脂肪酸(P = 0.068)和总SCFA(P = 0.089)含量呈增加趋势,苯乙胺含...

This study was conducted to compare the effects of herb residue(HR) and fermented HR on fecal microbes and their metabolites in sows, to provide the basis for their application in sow production. Sixty crossbred sows with the same expected date of delivery during the 2 to 4 parities were used and randomly allocated to one of three groups with 20 replicates. The diets were supplemented with 2 kg / t of rice bran(control group), 2 kg / t HR, or 2 kg / t fermented HR, respectively, in the same basal diets. These diets were fed from 85 days post service to postpartum 21 days. Eight sows per group ...
