Study on Seasonal Variation in Semen Characteristics, Semen Cryopreservation and Artificial Insemination in Elk Deer

엘크 사슴의 계절에 따른 정액성상 변화, 정액 동결 및 인공수정에 관한 연구

  • Published : 2007.08.31

Abstract

This study was designed to investigate the seasonal variation in semen characteristics and the change of motility during semen frozen/thawed, and conception rates were observed following AI at the different times after estrus synchronization. Semen collected from March to May showed significantly lower semen quality than the other months (P<0.05) and semen characteristics (volume, total sperm and motility) were significantly higher in October. Sperm motility after thawing in frozen semen were significantly lower in non-breeding season than in breeding season (P<0.05). Conception rate after treatment of estrus synchronization and AI different time after CIDR device removal, at 60 hour was higher than those of any other times through AI but there was no significantly difference between AI times. Semen characteristics change gradually during the breeding and non-breeding season. These results were considered as a model for the use of assisted reproductive techniques for AI of deer in Korea.

본 연구에서는 엘크 사슴의 계절별 정액성상 변화, 동결정액의 융해 후 활력 및 발정동기화 후 인공수정 시간이 수태율에 미치는 영향을 조사하여 효율적인 인공수정 방법을 제시코자 시도하였다. 수사슴에서 정액의 연중 변화는 정액량, 정자 농도, 총 정자 수 및 정자 활력은 7월부터 급격히 증가 되어 정액량과 총 정자 수 및 정자 운동성은 10월에 최고치에 달했고, 정자 농도는 9월에 가장 많은 것으로 조사 되었다. 그 후 정액량, 정자농도, 총 정자 수 및 정자 운동성은 점진적으로 감소하여 정액 양, 정자 농도는 4~6월, 총 정자 수는 4~5월 및 정자 운동성은 6월에 최저 수준으로 감소하였다.번식계절(9~2월)과 비번식계절(3~8월)의 정자 농도, 총 정자 수 및 정자 운동성은 번식계절이 유의적으로 높게 조사되었다(P<0.05). 번식계절과 비번식계절에 채취한 정액의 동결과정 중에 정자 운동성의 결과는 채취 직후, 5℃냉각 후 및 동결 융해 후 활력이 번식계절이 높은 것으로 조사 되었다(P<0.05).인공수정 시간에 따른 수태율은 CIDR 제거 후 60시간에 인공수정 한 처리구가 수태율이 다른 시간들 보다 다소 높았으나 유의적인 차이는 나타나지 않았다.이러한 연구 결과는 엘크 사슴에서 정액 생산과 인공수정을 수행함에 있어 유용한 자료로 이용 될 수 있으며, 발정동기화 후 호르몬 변화, 배란 및 수정 적기 등에 관한 연구가 추가적으로 수행되어야 할 것으로 사료된다.
