试验旨在研究断奶SD大鼠日粮中补充酿酒酵母发酵液，对其生产性能、肠道发育、血液理化指标及免疫功能的影响。随机选取30只断奶SD大鼠分成对照组、酿酒酵母组及抗生素组，饲喂16 d后，测定其肠道形态及黏膜总蛋白、DNA及RNA含量，血液理化指标及免疫功能。结果表明，酿酒酵母组SD大鼠生产性能要极显著高于对照组（P＜0．01），与抗生素组差异不显著（P＞0．05）；酿酒酵母组其肠道黏膜总蛋白、DNA及RNA含量较对照组有极显著提高（P＜0．01），与抗生素组无差异（P＞0．05）；酿酒酵母组血液理化指标降低（P＜0．01），与抗生素组无差异（P＞0．05）；免疫功能和肠道形态，各组间无差异（P＞0．05）。试验结果显示，在断奶SD大鼠日粮中添加酿酒酵母发酵培养液，能够明显提高其生产性能，促进肠道生长发育，同时也降低血液中乳酸脱氢酶及肌酸激酶水平，减少断奶后应激。

To study the effects of Saccharomyces cerevisiae on growth performance ,intestine development , physio‐biochemical and immune function of early weanedrat ,a total of 30 weaned‐SD rats were randomly divided into 3 treatments as follows:the control group ,the S .cerevisiae group ,and the antibiotic group in the current re‐search .The intestine development ,physio‐biochemical and immune function were assayed after 15 days .The re‐sults showed that the growth performance of weanedrat was significantly improved in the S .cerevisiae group com‐pared with the control group (P<0 .01) ,but not so evidently compared with that of the antibiotic group (P>0 . 05) .The contents of total protein ,DNA ,and RNA in the S .cerevisiae group revealed the same tendency as above when compared with the control group (P<0 .01)and the antibiotic group (P>0 .05) .The physio‐biochemical of the S .cerevisiae group was significantly decreased than the control group (P<0 .01) ,but was comparable with that in the antibiotic group ( P> 0 .05 ) . Additionally , the immune function and intestine development had no differences in the S .cerevisiae group compared with the control group and antibiotic group (P> 0 .05) .The weanedrat diet supplement with S .cerevisiae was effective to enhance growth performance ,stimulate intestine de‐velopment and reduce the stress in conclusion .
