Abstract:

将160头体质量27kg左右的杜×(长×梅)三元杂交商品猪随机分成试验组和对照组,每组设4个重复,每个重复20头,公母各半。在试验组基础日粮中添加75mg.kg-1脂肪细胞膜蛋白抗体(简称OAAb),饲喂104d后,从每组选出体质量相近的12头猪(公母各半)屠宰,记录内脏器官和脂肪组织质量,同时采集血样。结果显示试验组平均日增质量、饲料报酬分别提高13.03%(P<0.01)和7.49%;试验组背膘厚、肾周脂肪指数、肠系膜脂肪指数和皮下脂肪指数分别下降24.14%(P<0.01)、27.27%(P<0.05)、20.42%(P<0.01)和29.11%(P<0.01),而肌内脂肪含量则不受影响;血清游离脂肪酸浓度在处理后明显升高(P<0.01),血清葡萄糖和甘油三酯浓度无明显差异;脾脏质量显著增加(P<0.05),但不影响肝脏和肾脏质量。提示口服OAAb可抑制猪的脂肪沉积,改善猪的胴体品质。
