乳酸杆菌对仔猪肠道微生物的影响

乳酸杆菌对常见的病原性大肠杆菌、猪霍乱沙门氏菌和金黄色葡萄球菌具有一定的抑菌作用。动物接种试验证明,试验分离获得的乳酸杆菌饲喂动物安全。在调整仔猪肠道菌群方面：试验各组效果较对照组差异均显著p〈0.05）,试验二组的效果最好,在增加乳酸杆菌方面,比试验一组高18.5%,比对照组高37.5%,在减少大肠杆菌方面,比试验二组高6.25%,在增加肠道细菌总数方面,比试验一组高21.5%,说明乳酸杆菌对改善仔猪肠道环境具有一定的作用。

On the Effect of Lactic Acid Bacillus on Intestines Say Microorganism

The lactic acid bacillus had some certain inhibitory effects to common pathogenicity bacterium bacillus coli,pig cholera and staphylococcus aureus.The test of animal inoculates proved the lactic acid bacillus obtained by testing separating was safety to feed animals.In the field of the group in adjusting the piglet intestines road bacterium： The differences of the effects in every group than the contrasting group were significant（0.05）.The testing effect of second group was is best,in the field of increasing lactic acid,18.5% higher than the experiment group,37.5% higher than the collation group,in cutting down bacillus coli aspect,6.25% higher than the group of second two,the intestines 21.5% higher than the group of first group,indicated that the lactic acid bacillus had some certain effects in the field of increasing the environment of piglet intestines road.
