摘要：

This study aimed to evaluate the effects of birth type and family on quantitative and qualitative meat traits in Santa Ines lambs and to do a descriptive study of variation inside of breed. A total of 50 carcass and meat traits were evaluated in up to 101 lambs slaughtered at 424 days of age. Random effect of family, the fixed effect of birth type (single or double) and year, and the covariates of dam's weight at weaning and age (in days) at slaughter were inserted in the model. This study shows that some carcass and meat traits in Santa Ines raised on pasture has large variability, specially for meat cut yields, several carcass non-components yields, and rib eye area, subcutaneous fat thickness, shear force, cooking losses, and b* color parameter. The birth type effect influenced (P < 0.05) rump width; reticulum, leg, heart and kidney yields; and the carcass pH at 24 h after slaughter. The family effect was significant (P < 0.05) for cold carcass weight; hot, cold and true carcass yields; external carcass and leg lengths; perimeter and width of the rump; kidney, liver and tail yields; and carcass pH at slaughter.
