Fatores relacionados ao rendimento de carcaça de novilhos ou novilhas superjovens,terminados em pastagem cultivada. Ciência Animal Brasileira, Goiânia, v. 11, n. 1, p. 53-61, jan./mar. 2010.

The animals were finished with energetic supplementation on cultivated pasture. Twelve contemporary animals of each sex were used, all crossbred Nellore (3/8) x Hereford (5/8) from the same herd. Farm live weight, slaughterhouse live weight and hot carcass weight were superior in males, being 365.8; 350.4 and 203.4 kg, respectively, while the females showed 310.3; 294.5; and 168.6 kg, in the same order. Males also showed higher hot carcass dressing percentage in relation to farm live weight (55.6 vs 54.4%) and in relation to slaughterhouse weight (58.1 vs 57.2%) than females. The lower female dressing percentage was a result of the higher hide (9.03 vs 7.96%), inguinal fat in the udder of heifers or cod fat of steers (1.02 vs .67%), full digestive tract (19.35 vs 16.84%), empty rumen plus reticulum (2.34 vs 1.91%) and empty intestine (2.54 vs 2.11%) percentages. There was no significant difference between sexes in heart, liver, lungs, kidneys and spleen percentages, being, respectively, 0.40, 0.93, 1.01, 0.22 and 0.35% in males and 0.41, 0.98, 1.02, 0.22 and 0.30% in females, cited in the same order.porAcesso AbertoBrafordCouroÓrgãosRúmenSexoBrafordHideOrgansRumenSexArtigo
