2、5)。料肉比指標,試驗組1顯著低于其他3個處理組(P<0.05)。試驗組1仔豬對飼料的干物質表觀消化率與對照組差異不顯著(P>0.05),均顯著高于試驗組2(P〈0.05)。試驗結果表明,仔豬商業(yè)飼料在組合使用多種常規(guī)飼用抗生素的基礎上,單一添加飼用凝結芽孢桿菌能夠進-步改善斷奶仔豬的生產性能,然而單一添加枯草芽孢桿菌或凝結芽孢桿菌與枯草芽孢桿菌組合使用均沒有獲得顯著的正效應。關鍵詞:凝結芽孢桿菌;枯草芽孢桿菌;魅生長性能;王志祥(1965-),男,云南祿勸人,高級畜牧師,主要從事畜牧學研宄。作志斌E-mail:chengzb99@163.com。2017-09-10基金:云南省
