摘要
在一定的初冻温度范围内，用自制冷冻箱冷冻精液。经正交试验法筛选出影响精液食冻后活率的最桂剂量、冷冻高度和初冻温度水平搭配为250支、4cm、－100℃。采用单因素对分法试验对冷冻剂量进一步评选，取得了满意的效果．该成果经生产上推广应用效果较好。
The bull semen was froze in certain primary freezing temperature scope using semen freezing box made by themselves. The optimum doses, frozen helght and primary freezlng temperature which was inflencing the survival rate of frozen semen were 62. 5 ml (250× 0. 25 ml), 4 cm and - 100℃ respectively after screened by orthogonal exprimental design, the further screening for frozell doses using sirigle factor contrast partition exprimental design obtained the satisfactory results which dernonstrated the good effects in practices.
