【摘要】：[目的]研究雙益素對蛋雞盲腸微生態(tài)及蛋品質(zhì)的影響。[方法]選擇42周齡同一批次、健康的海蘭褐商品蛋雞3 780只,隨機(jī)分成試驗(yàn)組和對照組,對照組飼喂基礎(chǔ)日糧,試驗(yàn)組在基礎(chǔ)日糧中添加0.25‰雙益素,研究雙益素對蛋雞盲腸微生態(tài)指標(biāo)和蛋品質(zhì)的影響。[結(jié)果]與對照組相比,試驗(yàn)組盲腸乳酸桿菌含量提高0.063×108CFU/g,差異顯著(P0.05),大腸桿菌含量降低0.184×10~8CFU/g,差異顯著(P0.05);試驗(yàn)組雞蛋蛋殼厚度和蛋殼強(qiáng)度分別提高0.03 mm和3.31 N,差異顯著(P0.05);試驗(yàn)組雞蛋中蛋白質(zhì)、鈣和磷含量比對照組分別提高1.55%、0.012%和0.026%,差異顯著(P0.05)。[結(jié)論]雙益素能有效調(diào)控腸道微生態(tài)內(nèi)環(huán)境,改善蛋品質(zhì),提高雞蛋營養(yǎng)價值。
