摘要
本实验旨在研究常用的几种营养试剂对波尔山羊精子活率的影响。在25℃时,第一组(果糖、葡萄糖、蔗糖)精子活率最高(0.92);第二组(鲜牛奶、卵黄)精子活率最低(0.70);第三组(果糖、葡萄糖、蔗糖鲜、牛奶、卵黄)精子活率居中(0.81),差异极显著(P<0.01);在-196℃时,第三组精子活率最高(0.51);第一组精子活率最低(0.30);第二组精子活率居中(0.48),差异极显著(P<0.01)。结果表明,对于采精后立即实施人工授精或短时间保存精液(25℃),使用糖类试剂最好;若长时间保存精液(-196℃),糖类和奶类及卵黄混合试剂最好。
The study investigated the effects of common used nutritive reagents on bo'er goat sperm live-rate.At 25℃,the first group(fructose?glucose?sucrose)sperm live-rate is the highest(0.92);the second group(fresh milk?yolk)sperm live-rate is the lowest(0.70);the third group(fructose?glucose?sucrose?fresh milk?yolk)is placed in the middle(0.81),there is significantly difference(P<0.01).At -196℃,the third group sperm live-rate is the highest(0.51);the first group sperm live-rate is the lowest (0.30);the second group is placed in the middle (0.48),there is significantly difference(P<0.01).In conclusion,this study show put into effect insernination immediately after semen collection or preserve semen,in short time(25℃),sugur-like nutritive reagents is best;if long time preserve semen(-196℃),the reagents that sugar?milk and yolk mixed is best.
