Abstract

This study was carried out to evaluate the productive efficiency of Corriedale sheep of different conformation traits, reared on natural and/or cultivated winter pastures. At calving, the females were classified as medium (frame = 50 to 57.5 kg) and large (frame = 57.6 to 62 kg) regarding the size and as average (2 to 3 points) or high (3.5 to 4.5 points) regarding the body condition score. The experimental design was entirely randomized in a 2 x 2 factorial arrangement (two groups of body weights x two classes of body condition at calving). Sheep with medium body structure were lighter compared to large ones at calving (39.97 vs 48.16 kg, respectively) and at weaning (43.10 vs 50.22 kg, respectively). The production efficiency at calving and at weaning did not differ between medium (46.91 and 44.24 kg) and large sheep (47.83 and 45.69 kg), respectively. Sheep with average body condition at calving compared with sheep with high body condition showed no significant differences for productive efficiency at calving (46.89 vs. 47.82) and at weaning (44.10 vs. 45.83). The animal size and the body condition score at calving did not influence the production efficiency of sheep herds on grazing.
