植物乳杆菌对断奶仔猪生产性能和血液生化指标的影响

通过断奶仔猪的饲养试验和消化试验来评定植物乳杆菌对断奶仔猪的营养价值。试验结果表明植物乳杆菌能显著提高断奶仔猪的试验末重,试验组比对照组提高13.85%(P<0.05);血清总蛋白试验组比对照组提高16.31%(P<0.05),而血清尿素氮试验组比对照组降低36.21%(P<0.05),可见植物乳杆菌能显著提高断奶仔猪血清总蛋白含量和显著降低血清尿素氮含量;试验组CD4 比对照组高22.22%,试验组CD4 /CD8 比对照组高16.95%,提高了断奶仔猪细胞免疫水平;试验组同对照组相比,空肠、盲肠乳酸菌数量分别提高了9.65%、18.11%,空肠、盲肠大肠杆菌数量分别降低了9.26%、12.32%,空肠、盲肠沙门氏菌数量分别降低了5.93%、17.58%,改善了肠道微生物环境;小肠绒毛长度试验组比对照组高44.36%,胃底腺胃小凹的深度试验组比对照组深17.74%。

Effect of the Lactobacillus Plantarum on Performance and Serumbiochemical Indices of Weaning Piglets

The feeding experiment and the digestion trial were conducted with weaning piglets,which evaluated the nutritional value of lactobacillus plantarum.Compared with the control group,the final weight and the serum total protein in the trial group were significantly improved by 13.85%(P<0.05)and 16.31%(P<0.05),respectively;but the serum urea nitrogen decreased by 36.21%(P<0.05).The trial group had improved the cell immunity level,the CD~ _4 and CD~ _4/CD~ _8 were improved by 22.22% and 16.95%,respectively.The lactic acid bacteria contents of the jejunum and the cecum in the trial group were improved by 9.65% and 18.11%,but the E.coli contents of the jejunum and the cecum decreasd by 9.26% and 12.32%,the Salmonella contents of the jejunum and the cecum decreasd by 5.93% and 17.58%;the villus length in the small intestine raised by 44.36%,while the gastric pits altitude in the fundic gland improved by 17.74%.
