Abstract:

本试验旨在研究益生菌制剂对早期断奶仔猪肠道pH、黏膜形态结构和挥发性脂肪酸含量的影响。选用48头平均体重为(6.39±0.42)kg的(21±2)日龄"杜×长×大"三元杂交断奶仔猪,按性别、体重和窝源基本一致原则随机分为2个组,每个组4个重复,每个重复6头猪。试验1组为对照组,采用基础饲粮;试验2组为益生菌组,每千克基础饲粮中添加1×109CFU活菌。试验期为21d。结果表明:1)28日龄时,益生菌组回肠内容物pH显著低于对照组(P<0.05)。2)和对照组相比,添加益生菌制剂,28日龄时,显著增加空肠、回肠绒毛高度和上皮内淋巴细胞数量(P<0.05),显著提高回肠杯状细胞数量(P<0.05),显著降低回肠隐窝深度(P<0.05);35日龄时,显著增加空肠、回肠绒毛高度(P<0.05),显著提高空肠上皮内淋巴细胞数量(P<0.05),显著降低空肠、回肠隐窝深度(P<0.05);42日龄时,显著增加空肠、回肠绒毛高度,显著提高空肠上皮内淋巴细胞和杯状细胞数量(P<0.05),显著降低空肠隐窝深度(P<0.05)。3)28日龄时,益生菌组盲肠内容物中丁酸和乳酸含量显著高于对照组(P<0.05);35日龄和42日龄时,益生菌组盲肠内容物中乙酸、丙酸、丁酸和乳酸含量显著高于对照组(P<0.05)。由结果可知,添加益生菌制剂能改善断奶应激对绒毛高度和隐窝深度的影响,提高肠道淋巴细胞数量和挥发性脂肪酸含量,降低肠道pH,从而缓解断奶应激对肠道环境的影响。
