Abstract: The performance of eight 1½-year -old and twenty-five 2½ to 3½-year-old Romney rams and eight 2½ to 3½-year-old Cheviot rams, in pen and paddock libido tests, and their flock mating performances at different ram:ewe ratios was recorded. All rams except one Cheviot were sexually active in the libido tests. There was no effect of age or breed of ram on their performance in the pen libido tests, and there was no difference between the performances of the rams in two pen libido tests conducted two weeks and one week prior to the commencement of flock mating. Variation between rams in flock mating performance, measured by the percentage of total ewes that were marked by each particular ram, could not be accounted for by variation in ram:ewe ratio, age or breed of ram, or any of the libido criteria measured. |
