본 연구는 사슴의 조기 임신진단기법을 개발하기 위해 엘크 61두를 발정동기화 처리하고 인공수정하여 수정 후 20~24일에 38두의 혈액을 채취하여 혈청을 분리한 후 혈중 progesterone(P$_4$) 농도를 분석하였다. 혈중 P$_4$ 농도의 분석은 Walac Delpia 123(Delpia Co, Holland)을 이용하여 progesterone kit(Delpia, Co. 미국)로 분석하였으며, 임신진단의 정확도를 비교하기 위하여 수정 후 60일령에 직장검사와 초음파진단을 실시하였다.Table 1은 음파진단, 직장검사 및 P$_4$분석에 의한 임신진단 결과를 나타내었다. 진단방법에 따른 수태율은 초음파진단 72.1%, 직장검사 60.7%, P$_4$ 농도분석 68.9%, 초음파진단과 직장검사에서 동시 임신으로 판정된 것은 57.4%를 각각 나타내었다. 이상의 결과로 보아 사슴은 임신초기에 태아사멸이 많이 발생하는 것으로 추정되며, 임신진단기법 개발을 위해서는 지속적인 연구가 추진되어야 할 것으로 사료된다.

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.

This study was carried out to investigate the main causes of sterility influenced on conception rate for artificial insemination in Elk deer. We carried out A.I work for 202 hinds elk deers at breeding season during the period of 02 Sep. thru 01 Oct. of 2
