Twelve crossbred Texel x Bergamácia (TB), 12 crossbred Texel x Santa Inês (TS) and 12 purebred Santa Inês (SI) lambs were individually finished in fedlot for 50 days (from 130 to 180 days of age). Each genetic group consisted of six males and six females, fed three different diets: 1 = without coffee hulls (control); 2 = with coffee hulls in nature; 3 = with coffee hulls treated of with urea. The rumen/reticulum (RR) of the animals fed diets 1 and 3 were significantly heavier than those fed diet 1. The abomasum (ABO), liver (FIG) and pancreas (PAN) of the lambs fed diet 3 were lighter than the animals fed diet 2. The TB and TS of crossbred lambs showed greater weights of head (CAB), foot/shin (PEC), omasum (OMA), abomasum (ABO), small intestine (IND) and large intestine (ING). The males showed heavier weights of blood (SAN) and RR than the females. The weights of skin (PEL), fat (GOR), esophagus/trachea (ET), heart (COR) and lung (PUL) were also analyzed and were not affected by the diets, genetic groups and sex. However, GOR content tended to be greater for females.
