Effects of Magnetic Field on the Quality of Chicken Semen Stored at Low Temperature

[目的]探讨磁化处理对低温保存鸡精液品质的影响。[方法]将5 m l新鲜精液平均分为5份,每份按1∶4（V/V）进行稀释,其中1份为对照组,不作磁化处理,其余4份分别放入自制磁化器中磁化6、12、24、48 m in,5组均置于2-4℃的冰箱中保存,定时观测精子活率、存活时间、生存指数和畸形率。[结果]精液经磁化后活率提高,并且有效生存指数明显优于对照组,尤以磁化24 m in效果最明显,比对照组提高了7.75%,而精子的畸形率磁化组低于对照组。[结论]磁化处理可有效提高冷冻保存鸡精液的品质。

[ Objective ] The study aimed to explore the effects of magnetic treatment on the quality of chicken semen stored at low temperature. [ Method ] 5 ml fresh chicken semen was divided into five groups equally, each of which was diluted at the volume ratio 1：4. With the group without magnetic treatment as the control, the other four groups were magnetized for 6,12,24 and 48 min in the self-made magnetizer, respectively. Subsequently, all the five groups were stored at 2 - 4 ℃, and the sperm motility, survival time, survival index and deformity rate were observed regularly. [ Result] Comparing with the control group,the magnetic groups showed higher sperm motilities and effective survival indices as well as lower deformity rates. The effective survival index of the group magnetized for 24 min was the highest and increased by 7.75% in contrast to the control. [ Conclusion] Magnetic treatment could effectively enhance the quality of chicken semen stored at low temperature.
