Abstract

This study was done to find out the methods of long-term use of liquid boar semen in 100 ml plastic bottle for artificial insemination and to investigate differences between Lactose-Egg yolk and Biitschwiler diluents according to storage temperature, and effect of final glycerol concent ration in Lactose-Egg yolk diluent. Liquid boar semen diluted with Lactose-Egg yolk diluent showed significantly higher sperm motility (p<0.05) after 0.5 and 2h incubation at 37$^{\circ}C$,than Butschwiler diluent at all storage length when it was preserved in the 5$^{\circ}C$ refrigerator. The NAR acrosome in Lactose-Egg yolk diluent a after 0.5 and 2h incubation at 37$^{\circ}C$, respectively, during preservation periods was similar to that in Biitschwiler diluent. When liquid boar semen was preserved at 15$^{\circ}C$, liquid boar semen in the Butschwiler diluent showed significantly higher percentages of sperm motility and NAR acrosome from third day to seventh than that in Lactose-Egg yolk diluent. In the effect of final glycerol concentration of liquid boar semen in the Lactose-Egg yolk diluent, the final glycerol concentration of 2% showed higer percentages of sperm motility and NAR acrosome than that of 0, 1, 3, and 5%. Farrowing rate, litter size and average pig weight at birth did not differ significantly between Lactose-Egg yolk and But schwiler diluents. As a result of this study, we found out that liquid boar semen can be stored for 6-7 days at 5$^{\circ}C$ in Lactose-Egg yolk diluent and at 15$^{\circ}C$ in Butschwiler diluent.

본 연구는 돼지 액상정액을 인공수정용 100ml 플라스틱 병에 보존하면서 Lactose-Egg yolk 희석액과 B tschwiler 희석액 간에 보존 온도별 차이를 조사하고, Lactose-Egg yolk 희석액에서의 글리세롤 농도의 효과를 조사하여 돼지 액상정액을 좀더 장기간 사용할 수 있는 방법을 찾고자 실시하였다. 돼지 액상정액을 5$^{\circ}C$ 냉장고에 보존하면서조사한 바에 의하면, 37$^{\circ}C$에서 0.5 및 2시간 배양 후의 정자 운동성은 전체 보존기간동안 Lactose-Egg yolk 희석액이 B tschwiler 희석액보다 유의하게 (P,0.05) 높게 나타났고, 정상첨체비율은 두 희석액간에 차이가 없었다. 돼지 액상정액을 15$^{\circ}C$에 보존하면서 조사한 바에 의하면, 3일부터 7일 보존시까지 정자 운동성과 정상첨체비율에 있어서 B tschwiler 희석액이 Lactose-Egg yolk 희석액보다 유의하데 높게 나타났다. Lactose-Egg yolk 희석액을 이용한 돼지 액상정액의 글리세롤 농도의 효과에 있어서는 최종 글리세롤 농도가 0, 1, 3 및 5%보다 2%일 때 가장 높은 정자 운동성과 정상첨체비유을 나타내었다. 분만율, 복당 생존자돈수 그리고 출생시 평균 생시체중은 Lactose-Egg yolk 희석액과 B tschwiler 희석액간에 차이가 없었다. 이상의 연구 결과를 종합해 볼 때 Lactose-Egg yolk 희석액은 5$^{\circ}C$에서 B tschwiler 희석액은 15$^{\circ}C$에서 6~7일 동안 돼지 액상정액을 보존할 수 있었다.
