Abstract
Growth performance, slaughter traits and carcass characteristics of Awassi (A), Tushin (T) and AwassixTushin (AxT) male and female lambs weaned at 2.5 months of age and subjected to semi-intensive feeding during grazing period for 70 days were evaluated. There was no difference among genotypes in terms of daily liveweight gain and the amount of concentrate feed consumed in addition to pasture per unit liveweight gain. AxT crossbreds had larger (P<0.05) longissimus dorsi (LD) area and hot dressing percentage. Rib, hindshank and kidney fat were significantly affected (P<0.05; P<0.01) by genotype. Crossbred lambs were superior to both A and T lambs in terms of certain carcass traits.
