【摘要】：本試驗(yàn)旨在比較中藥渣和發(fā)酵中藥渣對(duì)母豬糞便微生物及其代謝產(chǎn)物的影響,為其在母豬飼糧中的應(yīng)用提供依據(jù)。試驗(yàn)選用2~4胎次、預(yù)產(chǎn)期相近的二元母豬60頭,隨機(jī)分為3組,每組20頭。3組分別在基礎(chǔ)飼糧中添加2kg/t的米糠(對(duì)照組)、2kg/t的中藥渣和2kg/t的發(fā)酵中藥渣。從妊娠85d開(kāi)始飼喂,到產(chǎn)后21d結(jié)束。分別于妊娠110d和產(chǎn)后21d,每組隨機(jī)收集8頭母豬的新鮮糞便樣品,測(cè)定微生物數(shù)量以及短鏈脂肪酸(SCFA)和生物胺的含量。結(jié)果表明:與對(duì)照組相比,中藥渣組母豬產(chǎn)前糞便中丙酸含量顯著增加(P0.05),丁酸(P=0.086)、直鏈脂肪酸(P=0.068)和總SCFA(P=0.089)含量呈增加趨勢(shì),苯乙胺含量顯著降低(P0.05);產(chǎn)后糞便中1,7-庚二胺和酪胺含量顯著降低(P0.05)。發(fā)酵中藥渣組母豬產(chǎn)前糞便中1,7-庚二胺、亞精胺和精胺含量均顯著降低(P0.05),乙酸(P=0.068)、丁酸(P=0.082)、直鏈脂肪酸(P=0.058)和總SCFA(P=0.064)含量呈增加趨勢(shì);產(chǎn)后糞便中乳酸桿菌數(shù)量顯著增加(P0.05);產(chǎn)前和產(chǎn)后糞便中大腸桿菌數(shù)量、酪胺含量顯著降低(P0.05)。綜上,飼糧添加中藥渣或發(fā)酵中藥渣可改善圍產(chǎn)期母豬后腸微生物菌群平衡,增加SCFA含量,減少生物胺含量,這有利于機(jī)體的能量供給和健康。
[Abstract]:The purpose of this experiment was to compare the effects of traditional Chinese medicine residue and fermentative residue on fecal microbes and metabolites of sows, and to provide the basis for their application in sows diet. Each group was randomly divided into three groups. Each group (20 heads. 3) was fed with 2 kg / t of rice bran (2 kg / t of traditional Chinese medicine residue and 2 kg / t of fermentative residue of 2 kg / t) in the basal diet from day 85 of gestation. At the end of 21 days postpartum, fresh fecal samples of 8 sows were collected randomly on day 110 of gestation and 21 days after delivery, respectively, and the amount of microbes, SCFAs and biogenic amines in each group were determined. The results showed that: compared with the control group, there were no significant differences between the two groups. The contents of propionic acid, butyrate, straight chain fatty acid and total SCFA-P0. 089) in the feces of sows in traditional Chinese medicine group were significantly increased, and the contents of P0. 086, P0. 068) and total SCFAA P0. 089) were increased. The contents of phenylethylamine and tyramine in postpartum feces decreased significantly, while those in feces of fermentative residue group decreased significantly. The contents of spermidine and spermine decreased significantly in P0.05, P0. 068, P0. 082, P0. 058) and SCFA-P0. 064), and the number of lactobacillus in postpartum feces increased significantly, and the number of Escherichia coli in pre- and postpartum feces was significantly increased. Tyramine content significantly decreased P0. 05%. In conclusion, dietary supplementation of traditional Chinese medicine residue or fermentative residue could improve the balance of microflora, increase SCFA content and decrease biogenic amine content in perinatal sows, which was beneficial to the energy supply and health of the body.
