摘要:

为研究乳酸菌发酵饲料对断奶仔猪生长性能和小肠健康的影响，试验选取48头28日龄体况良好、体质量相近的杜长大三元杂交断奶仔猪，随机分成2组，每组4个重复。对照组仔猪饲喂无抗乳猪全价配合饲料，试验组仔猪饲喂添加20%乳酸菌发酵饲料的全价料，试验共持续29 d。结果表明，与对照组比较，饲喂添加发酵饲料的全价料显著提高平均日采食量，但对仔猪免疫器官质量及其脏器指数无显著影响，饲喂发酵饲料显著降低仔猪胃、回肠及结肠食糜的pH值，显著提高仔猪结肠中乙酸含量，对仔猪空肠和回肠的肠绒毛高度、隐窝深度以及二者之比无显著性影响，显著提高仔猪粪便中的乳酸菌数量和降低大肠杆菌的数量，对沙门氏菌的数量无显著影响。结果表明，乳酸菌发酵饲料对断奶仔猪肠道微生物组成有改善效果，但对生长性能和形态学指标无明显影响。
