摘要
试验选用8头荷斯坦种公牛，研究了日粮中添加小肽对性反射时间、精液品质的影响。结果表明：日粮中添加小肽能显著提高荷斯坦种公牛的体质状况及精液的鲜精活力、精子密度和顶体完整率；性反射时间明显减少。
8 Hol - stein cows were selected in this experiment. Study on the sex response time and the sperm quality when added daily feed with peptide. Results proved that when added the daily feed with peptide the hol -stein cows＇body and the sperm＇s fresh activities can be enhanced. The density of sperm can be remarkably increased. The response time can be decreased.
