【摘要】 试验研究发酵中草药添加剂对仔猪生长性能、血清免疫指标及肠道菌群的影响。选择体重15 kg左右、日龄相近的健康杜长大三元杂种断奶仔猪80头(公母比1∶1),随机分为抗生素组和发酵中草药添加剂组,每组设4个重复,每个重复10头,公母各半,单圈饲养。预试期6 d,试验期33 d。抗生素组在基础饲粮中添加15%金霉素500 g/t、20%土霉素钙1 000 g/t,发酵中草药添加剂组是在基础饲粮中添加2%发酵中草药添加剂。试验结果显示:1)与抗生素对照组相比,发酵中草药添加剂组平均日增重上升10.43%(P<0.01),料重比下降9.04%(P<0.01)。2)与抗生素对照组相比,发酵中草药添加剂组总抗氧化能力上升76.58%(P <0.05),总蛋白上升9.37%(P <0.05),血糖、尿素氮、谷草转氨酶、谷丙转氨酶两组差异都不显著(P>0.05)。3)与抗生素对照组相比,发酵中草药添加剂组IgM上升79.02%(P<0.01),IgA、IgG两组差异都不显著(P>0.05)。4)与抗生素对照组相比,发酵中草药添加剂组乳酸菌含量上升6.25%(P>0.05),大肠杆菌含量下降9.81%(P>0.05)。综上所述,与抗生素对照组相比,发酵中草药添加剂组使猪的生长性能、总抗氧化能力和免疫指标显著提高,肠道菌群结构有一定程度的改善。更多还原

【Abstract】 The purpose of the study was to explore the effect of fermented Chinese herbal medicine additives on growth performance, serum immune index and intestinal flora of piglet. Optional similar weight, 80 healthy piglet. They were randomly divided into two groups, the antibiotic group(15%Kindamycin 500 g/t +20% Tutomycin 1 000 g/t), fermented Chinese herbal medicine additives group(2%fermented Chinese herbal medicine additives), each group had 4 replicates, and each repetition had 10 pigs fed singly. The experiment lasted 33 days. The results showed that, compared with the antibiotic group, fermented Chinese herbal medicine additives group ADG increased 10.43%(P <0.01), F/G decreased 9.04%(P<0.01). T-AOC increased 76.58%(P<0.05), total protein increased 9.37%(P<0.05),blood sugar, urea, GPT, GOT had no significant changes between group. IgM increased 79.02%(P<0.01), IgA and IgG had no significant changes between groups. Pig intestinal tract’bacillus acidi lactici content increased 6.25%(P>0.05), pig intestinal tract’bacillus coli contentthe decreased 9.81%(P>0.05). It was concluded that feed antibiotics replaced fermented Chinese herbal medicine additives on growth performance, T-AOC, serum immune index and Intestinal flora improved significantly.更多还原
