【摘要】：[目的]研究双益素对蛋鸡盲肠微生态及蛋品质的影响。[方法]选择42周龄同一批次、健康的海兰褐商品蛋鸡3 780只,随机分成试验组和对照组,对照组饲喂基础日粮,试验组在基础日粮中添加0.25‰双益素,研究双益素对蛋鸡盲肠微生态指标和蛋品质的影响。[结果]与对照组相比,试验组盲肠乳酸杆菌含量提高0.063×108CFU/g,差异显著(P0.05),大肠杆菌含量降低0.184×10~8CFU/g,差异显著(P0.05);试验组鸡蛋蛋壳厚度和蛋壳强度分别提高0.03 mm和3.31 N,差异显著(P0.05);试验组鸡蛋中蛋白质、钙和磷含量比对照组分别提高1.55%、0.012%和0.026%,差异显著(P0.05)。[结论]双益素能有效调控肠道微生态内环境,改善蛋品质,提高鸡蛋营养价值。
