摘　　要：旨在研究丁酸梭菌、凝结芽孢杆菌和酿酒酵母发酵物对断奶仔猪生长性能、血清生化指标和肠道发育的影响。选取(21±2)日龄的健康大×长二元杂交仔猪80头,分成4组,每组20头,公母各半。对照组饲喂基础日粮,试验组分别在基础日粮中添加丁酸梭菌(20 g/t)、凝结芽孢杆菌(50 g/t)、酿酒酵母发酵物(5000 g/t)。日粮添加凝结芽孢杆菌可提高母猪的日增重(P<0.05)。日粮添加丁酸梭菌、凝结芽孢杆菌、酿酒酵母发酵物极显著提高断奶仔猪血清尿素(UREA)的含量(P<0.01),且日粮添加酿酒酵母发酵物显著提高断奶仔猪血清葡萄糖(GLU)的含量(P<0.05)。日粮添加丁酸梭菌、凝结芽孢杆菌、酿酒酵母发酵物显著提高空肠绒毛高度(P<0.05)。酿酒酵母组的空肠绒毛高度/隐窝深度显著高于对照组、丁酸梭菌组和凝结芽孢杆菌组(P<0.05)。日粮添加丁酸梭菌、凝结芽孢杆菌、酿酒酵母发酵物显著提高回肠绒毛高度(P<0.05)。由试验结果可知,日粮添加丁酸梭菌、凝结芽孢杆菌、酿酒酵母发酵物可能促进断奶仔猪肠细胞的成熟,提升肠道吸收营养物质的能力。This study was conducted to investigate the effects of Clostridium butyricum,Bacillus coagulans and Saccharomyces cerevisiae fermentation on growth performance,serum biochemical indexes and intestinal maturation of weaned piglets.Eighty healthy Yorkshire×Landrace piglets at the age of(21±2)days old were randomly divided into 4 groups,20 piglets in each group,half male and half female.The control groups were fed with the basic diet,while the test groups were fed with the basic diet supplemented with Clostridium butyricum(20 g/t),Bacillus coagulans(50g/t)or Saccharomyces cerevisiae fermentation(5000 g/t).The adding Bacillus coagulans to the diet increased the daily gain of weaned female piglets(P<0.05).The addition of Clostridium butyricum,Bacillus coagulans or Saccharomyces cerevisiae fermentation extremely significantly increased the serum urea(UREA)content of weaned piglets(P<0.01),and the addition of Saccharomyces cerevisiae fermentation significantly increased the serum glucose(GLU)content of weaned piglets(P<0.05).The addition of Clostridium butyricum,Bacillus coagulans or Saccharomyces cerevisiae fermentation significantly increased the height of jejunal villus(P<0.05),and the jejunal villus height/recess depth in Saccharomyces cerevisiae fermentation group was higher than that in control group,Clostridium butyricum group and Bacillus coagulans group(P<0.05).The addition of Clostridium butyricum,Bacillus coagulans or Saccharomyces cerevisiae fermentation significantly increased the height of ileal villus(P<0.05).The test results showed that the addition of Clostridium butyricum,Bacillus coagulans or Saccharomyces cerevisiae fermentation in the diet may promote the maturation of intestinal cells of weaned piglets and improve the ability of intestinal absorption of nutrients.
