Abstract

To preserve chicken genetic materials like cryopreserved spermatozoa, various kinds of freezing agents like glycerol, dimethylsuloxide, dimethylformamide or dimethylacetamide have been used for rooster semen preparation. Recently, the usage of N-methylacetamide (MA) for Ogye rooster semen preservation resulted in hatched chicken successfully. In this study, we investigated the effects of 7, 9 and 11% of MA on the viability, fertility and hatchability of frozen-thawed rooster semen using artificial insemination. The results of viability, fertility and hatchability in frozen semen with 7%, 9% or 11% MA were $35.16{\pm}6.12%$, $67.83{\pm}15.3%$ and $66.2{\pm}16.3%$ of motile sperm rate, 21.5%, 34.7% and 25% of fertility rate, and 100%, 89.5% and 87.5% of hatchability rate. The results of control group with frozen semen were 96.0% of fertility rate and 92.2% of hatchability rate. With these results, the concentration range of MA as a freezing agent of rooster semen could be 7~9% of media. The higher concentration of 9 % MA could decrease the fertility rate of thawed semen not the rate of hatchability rate. So the use of MA without affecting fertility rate would be a key point of freezing method of rooster semen for poultry genetic resource preservation.

본 연구는 닭 정액의 동결 보존을 위하여 비 글리세롤성 동결 보호제 중 MA 농도가 정자의 생존율과 융해된 동결 정자를 인공수정을 실시하여 생산된 수정란의 수정율, 부화율을 조사하고자 실시하였다. 동결 보조제로써 MA의 효율성은 7%, 9% 및 11% 범위에서 동결을 실시하였을 때, 정자의 생존율은 $35.16{\pm}6.12%$, $67.83{\pm}15.3%$$66.2{\pm}16.3%$로 관찰되었으며, 융해된 정자를 인공수정을 실시하여 생산된 수정란의 수정율은 21.5%, 34.7% 및 25%로 관찰되었으며, 수정된 수정란의 부화율은 100%, 89.5% 및 87.5%로 관찰되었다. 대조군으로써 신선 정액은 수정율이 96.0%로 관찰되었고, 부화율은 92.2%로 관찰되었다. 9% MA를 이용한 간이 동결법으로 생산된 동결 정자를 이용하여 3주간 수정란을 검사하였을 때, 수정율은 비록 35.3%로 관찰되었으나, 부화율은 90.3%로 관찰되었다. 이러한 결과에 따르면, 9% 농도로 MA 동결 보호제를 이용할 경우, 동결 및 융해된 정자를 이용하여 생산된 수정란에서 수정율을 감소시킬 수 있음을 보여주고 있으며, 부화율에는 영향을 주지 않음을 추정할 수 있다. 그러므로 수정율과 부화율에 나쁜 영향을 미치지 않고 가금 유전자원의 보존에 중요한 요인이 될 수 있는 적절한 농도의 MA 동결 보호제 범위는 7~9% 농도로 추정된다.
