摘要(Abstract)：

试验旨在研究益生菌发酵饲料对长白种公猪精液品质的影响。选取20头(150±20)日龄、体重(107.9±12.5)kg的成年长白公猪，采取单因素试验设计，随机分成5组，每组4头。对照组饲喂基础日粮，4个试验组分别以5%、10%、15%和20%发酵饲料替代基础日粮，50 d时采集血液，60 d时采集精液和粪便，测定血液生化、免疫、精液品质和粪便微生物相关指标。结果表明：与对照组相比，发酵饲料提高了公猪血清IgA、IgG和IgM的水平(P<0.05);5%、10%和15%发酵饲料替代组A级精子比例、精子活率、曲线速度、路径速度和摆动性(P<0.05)及精子顶体完整率均高于对照组(P<0.01)；与对照组相比，10%、15%发酵饲料替代组精子质膜完整率均升高(P<0.01)，发酵饲料均提高了公猪精浆果糖水平(P<0.05)；粪便微生物测序结果显示，与对照组相比，15%发酵饲料替代组降低了粪便中厚壁菌门的丰度(P<0.05)，提高了拟杆菌门的丰度(P<0.05)；公猪粪便菌群组成与精液品质存在显著相关。在本试验条件下，10%和15%发酵饲料替代组精液品质更好。
