Abstract
|
|
|
|
This experiment was carried out to study the behavior of the estrus cycle in sows shortened uterine horns and to see whether the embryos could be recovered nonsurgically. The uteri of sows(n=4) were surgically shortened. It took about 3 hours to surgically remove the middle section of both uterine horns. The lengths of the shortened uterine horns were 18.7 to 29.5cm. After treatment, two sows exhibited natural estrus and the intevals from surgery to estrus were 8 days and 15 days, respectively. But the sows were not successful on synchronization and superovulation with PMSG and PGF₂α. In the resurgery for confirmative examination, the sows had 6 and 7 corpus lutelin in ovaries, respectively. One sow had a small adhesion between the infundibulum and ovary, and the other sow had unilateral uterine obstruction at the sutured position and purulent materials in the uterus.
