Abstract

This study was conducted to investigate the effects of liquid rooster semen on reproductive ability in chicken. Raw and diluted semens were stored at 5$^{\circ}C$ cold temperature for 6, 30, and 54 hours after semen collection. There was no statistically difference in sperm motility throughout the 6 hours period of storage among raw semen and diluted semen groups with skim milk glucose solution (SM), egg yolk glucose solution (EY), and saline. But there was decrease in those throughout the period of 30 and 54 hours of storage. Sperm motility and normal sperm for the period of 30 and 54 hours of storage were significantly better in SM and EY diluted groups (P<0.05). Fertilization rates of rooster semen diluted with SM were 90.77, 87.70, and 59.46% for 6, 30, and 54 hours stored groups, respectively, those proved to be higher in SM-diluted group than other groups.

정액의 액상보존이 닭의 번식능력에 미치는 영향을 구명하기 위하여 계통이 분명한 재래닭을 정액 채취용 수탉으로 사용하였으며 인공수정용 암닭으로는 백색산란계를 사용하였다. 닭 정액을 채취 희석하여 5$^{\circ}C$ 냉장온도에서 6, 30, 54 시간보존하며 정액성상 검사와 함께 인공수정을 하였을 때, 원정액과 skim milk glucose액, egg yolk glucose액 및 saline에 희석된 정액의 정자운동성은 냉장보관 6 시간에는 처리간에 유의적인 차이가 없었으나, 냉장보관 30 및 54 시간에는 저하되는 경향이었다 그러나 skim milk glucose액과 egg yolk glucose액의 정자운동성과 정상정자율은 30 및 54 시간 냉장 보존을 하여도 원정액이나 saline액보다 현저히 높았으며 (P<0.05), 수정율에 있어서는 6, 30 및 54 시 간 냉장보존된 skim milk glucose희석정액에서 90.77, 87.70 및 59.46% 를 나타내어 다른 시험구보다 현저하게 우수한 결과를 보였다 .(P<0.05). 따라서 본 연구결과 skim milk glucose액은 닭의 액상정액 인공수정시 산업적 이용이 가능하다고 판단된다.
