The sexual season, i.e. the sexual cycle activity, of Finn × German Mutton Merino (Finn × GMM) ewes was found to extend from August to March. In a group of purebred German Mutton Merino (GMM) ewes the sexual season extended from June to January. After July-August and October-November lambings, 90-95% of the Finn × GMM crosses renewed postpartum sexual activity within 90 and 75 days, respectively. Only 40% of the November lambing purebred GMM ewes started new cycles within 105 days postpartum. The responsiveness of the Finn × GMM ewes to hormonal treatment was high (90-100%) during different months of the year. The fertility at the synchronized or induced oestrus was 60-75% throughout the year, with a mean litter size of 2.0 lambs per lambing. © 1980.
