The aim of the conducted research was to establish postpartum oestrous cycles and approximate data for mating Polish Merino sheep. 34 sheep were examined. During sheep laparotomy observations of ovaries and uterus were made on definite days of the postpartum period (1-78). It was stated that after about one-week of postpartum inactivity, the growth and development of follicles occurred in ovaries. First ovulations were noticed from the 15th to 18th day of postpartum, while processes connected with uterus involution were not completed. From the 14th to 18th day of postpartum, casting off of pregnant tissues from caruncules' surfaces into uterus cavity occurred. In the majority of sheep, regeneration of caruncules and purification of uterus cavity were completed by the 30th day of postpartum. The observed compatibility of the phases of ovary cycle with macromorphologically determined functional state of uterus after 30 days of postpartum, in the majority of tested sheep, suggests possibility of successful mating of Polish Merino sheep.
所开展研究的目的是确定波兰美利奴羊产后发情周期及配种的大致数据。对34只绵羊进行了检查。在绵羊剖腹手术期间，于产后特定天数（1 - 78天）对卵巢和子宫进行了观察。结果表明，产后约一周的静止期过后，卵巢中卵泡开始生长发育。首次排卵在产后第15至18天被观察到，而与子宫复旧相关的过程尚未完成。在产后第14至18天，怀孕组织从肉阜表面脱落至子宫腔内。在大多数绵羊中，肉阜的再生和子宫腔的净化在产后第30天完成。在大多数受试绵羊中，产后30天后观察到的卵巢周期各阶段与子宫大体形态确定的功能状态的一致性，表明波兰美利奴羊有成功配种的可能性。
