摘　　要：在原日粮的基础上,每头公牛每1d添加微量元素锌、碘和硒,可显著提高精子活力和精子顶体完整率,特别是原精活力提高了10.99%,营养剂对降低原精畸形率和提高精量也有一定的益处,但对原精密度反而有所下降,还需要进一步研究改进。Adding micro-elements (Zn,I and Se;in the day-diet of oxen could increase sperm vibrancy and the rate of gelea capitis integrity remarkably, especial the sperm vibrancy could be raised by 10.99%. The nutriment could reduce the rate of abnormal sperms and increase the seminal quantity, but the sperm density decreased to a certain extent,it would be studied further to improve.
