| Three different genetic groups were evaluated for growth up to slaughter and carcass quality for kill out, commercial cuts, non-carcass components, as well as carcass morphometric measurements. Pure Santa Ines (SI), ½ Ile de France × ½ Santa Ines (I × SI) and ½ Texel × ½ Santa Ines (T × SI) lambs were weighed weekly until they reached predetermined slaughter weight (30, 35, 40 and 45 kg). In both creep feeding and fattening the animals from crosses were superior to the Santa Ines hair sheep in terms of daily weight gain and weaned in less time. Crossbred animals also showed better performance than purebred Santa Ines in terms of commercial cuts and carcass weights. Correlations showed that fat depth and eye muscle area decreased with an increase in... |

| Genetic parameters and genetic and phenotypic trends were estimated for weight at weaning (WW) and visual scores (VS) of conformation (C), precocity (P), musculature (M) and navel (N) for Angus × Nellore crossbred calves. It was used 39,676 records from pre-weaning phase of animals born from 1992 to 2002 in mid-western, southeastern and southern Brazil. The components of covariance were estimated using REML, in animal model, considering as random the maternal and direct additive genetic effects, and as fixed, the effects of contemporaneous group, the genetic group of the animal and of the cow, and as covariates the age of the calf at weaning and the age of the cow at calving, both on days and with linear and quadratic effects, besides direct (DH) and... |
