| Two experiments were carried out to evaluate the influence of genetic group, pregnancy and animal age on the carcass traits and commercial cut patterns of sheep carcasses. In the first experiment, the effect of pregnancy and genetic group were evaluated on 61 eleven month old Santa Inês ewes and their crosses with Texel, Dorper and Ile de France. Experiment 2 was carried out with 132 Santa Inês nulliparous or lambed ewes slaughtered with ages ranging from 6 to 48 months to evaluate the influence of age on carcass traits. For both experiments, hot carcass weight, cold carcass weight, carcass yield, cold carcass yield and carcass length were measured, as well as the yields and percentages of shoulder, neck, loin, belly, ribs, leg and leg length and... |

| Purebred and crossbred calves (n = 3,871) were selected that were born in the sub-region of the Pantanal of Aquidauana (Brazil), derived from Nellore, Brangus, Wagyu, and ½ Brangus + ½ Nellore cows, which were artificially inseminated by bulls of the Aberdeen Angus, Red Angus, Brangus, Nellore, and Wagyubreeds. Parameters such as weaning weight, daily gain from birth to weaning, and the number of days to gain 160 kg, were assessed inthese calves and phenotypic correlations between the traits were evaluated. Data were analyzed using two statistical models. The first model included sire breed effects, the genetic group of the cow, sex, year of birth (AN), birth season (EN), and the interaction AN * EN. The second model included the genetic group of the calf,... |
