Effect of the ratio of teaser rams used prior to breeding on the reproductive performance of ewe hoggets

Abstract

The results of this study indicate that teaser-ram:ewe-hogget ratios as high as 1:197 can increase the percentage of ewe hoggets bred in the first 17 days of mating by at least 16.4%. Across the range of ratios used there was little difference in breeding pattern or pregnancy rate, although results might suggest ratios <or=1:32 are more effective compared with those >1:98.
