다국어 초록 (Multilingual Abstract)

This experiment was carried out to certify the effect of thawing methods and preservative
temperature on the sperm motility and fertility after thawing semen with plastic straws in
fresh and warm water. Sperm motility in vitro stored at room temperature after thawing were
conducted by the various storage hours. A tield frial after thawing semen with warmed water
in straws from Jeju native cows involving 4 technician and 800 cows first (or second) services
gave the following results. The thawing methods of warmed water for one minute in sperm motility were considerably higher than that in iced water during 12 hours after thawing semen,
however, the sperm survival index of ice-water showed a better results according as the time
passed away, but not significant differences. Preservative temperature at 5℃ (iced water) after
thawing gave significantly better fresults than that of thawed at 30℃ (warmed water). The NR
rate to 175 inseminations with semen thawed at 15-20℃ (fresh water) was 82.8% v, 80.9% for
610 inseminations thawed in warm water. Conception rate of the semen thawed in warm water
for 10-60 secs gave no significant differences among storage hours because that semen used to
be inseminated within one hour almost, but it decreased when semen thawed at the period of
one minute over.
