| Popis: | Studies are being conducted on the mode of inheritance of high reproductive performance of the Olkuska (O) sheep, a local Polish breed. Ten O were used in crosses with Polish Merino (PM) ewes. The ovulation rate of 60 F1 ewes (O x PM) and 129 pure PM ewes was stated by means of laparoscopy. The prolificacy of female ancestors, full-sisters and progeny of 3 O rams was extensively analysed. |
