摘  要：
为了探索包膜丁酸钠对断奶仔猪肠道菌群及生长性能的影响。试验将60头体重相近的28日龄阉割断奶仔猪随机分为2组:A组为对照组,仅饲喂基础日粮;B组为包膜丁酸钠组,在基础日粮的基础上添加0.03%包膜丁酸钠。试验期为28d,期间检测断奶仔猪不同肠段中肠道菌群种类及数量的变化,并记录各试验组仔猪的日采食量、日增重及仔猪的腹泻情况。结果显示:与对照组相比,基础日粮中添加包膜丁酸钠后,仔猪平均日增重提高7.22%,料肉比降低2.76%,且腹泻率与腹泻指数分别降低30.71%、33.85%;检测各肠段细菌含量,显示包膜丁酸钠可显著降低回肠中大肠杆菌的数量(P<0.05),增加盲肠和结肠中乳杆菌和双歧杆菌数量(P<0.05);观察试验后各组小肠组织形态发现,仔猪基础日粮中添加包膜丁酸钠后,小肠绒毛结构更为完整,绒毛更长更粗壮,且绒毛呈圆指状。结果表明,基础日粮中添加0.03%包膜丁酸钠可有效提高仔猪肠道有益菌的含量,促进小肠绒毛的发育,促进仔猪饲料的转化率,并能够降低仔猪腹泻率。

摘  要：
In order to find the effect of sodium butyrate on intestinal health and growth performance of weaned piglets,60 weaned piglets with similar weight were randomly divided into 2groups:one was the control group whose weaned piglets were fed with basal diet;the other was the coated sodium butyrate group whose weaned piglets were fed with basal diet and 0.03%coated sodium butyrate.The experimental period was 28 days.During the experiment,the changes of the type and quantity of the intestinal flora in the weaned piglets were detected,and the daily feed intake,daily gain and diarrhea were recorded.The results showed that compared with the control group,the group fed with coated sodium butyrate showed an increase of average daily gain by 7.22%,a decrease of feed to meat ratio by 2.76%,and the diarrhea rate and diarrhea index decreased by 30.71% and 33.85%.Escherichia coli,Staphylococcus aureus,Enterococcus,Lactobacillus,Bifidobacterium were calculated in each group.The results showed that coated sodium butyrate can significantly reduce the number of Escherichia coli in ileum(P<0.05),increase the number of lactic acid bacteria and bifidobacteria in cecum and colon(P<0.05).After the experiment,the morphology of intestinal tissue in each group was found after the addition of sodium butyrate in the basal diet,the structure of the small intestine was more complete,the villi were longer and stronger,and the villi were round finger.The basic diets supplemented with coated sodium butyrate can effectively improve the number of piglet intestinal bacteria,promote the transformation of piglet feed rate,promote the development of small intestine villi,and can reduce the diarrhea rate of piglets.
