【摘要】 选用 15kg左右的杜×长×大或杜×大×长三元杂交瘦肉型小猪 70头 ,分成 5个组 ,设 2个对照组及3个试验组。试验组分别在对照组基础上添加不同剂量的微生态制剂 ,以探讨饲养效果。结果表明 :“保得”微生态制剂可以代替抗生素、抗菌药物类生长促进剂 ;15～ 30kg小猪饲料中“保得”微生物制剂适宜添加量为 40 0mg/kg。试验对照组设计的杆菌肽锌 +阿散酸 +大蒜素组合能较好地预防 15～ 30kg小猪的腹泻更多还原

【Abstract】 three-way cross bacon type pigs with starting weight 15 kg of Duroc×Landrace×Large White or Duroc×Large White×Landrace were randomly divided into five groups. There were two control groups and three experiment groups. The treatment groups received the same basal diet supplemented with different dose of microbial feed additives(MFA).The results showed that “BaiDe” MFA could alternate antibiotic feed supplement. The suitable supplement of "BaiDe" MFA in ration of 15～ 30 kg swine was 400 mg/kg . Bacitracin zinc+arsanilic acid+garlic-premix could better prevent the diarrhoea of piglets.更多还原
