This study aimed to evaluate the effect of the la-tex ring applied on the ovarian pedicle, in Nelore breed heifers destined to slaughter, on the carcass and meat cha-racteristics. 23 Nelore female bovines were used in this study, eight months old (±2) and medium weight of 130 kg (±10) kept in Brachiaria            brizantha pasture and energetic mineralized salt supplementation, randomly distributed in two groups. The group I (GI) was constituted by 11 heifers castrated with by the application of the latex ring on the ovarian pedicle and the group II (GII) was composed by 12 non castrated heifers. The slaughter occurred when the animals reached the medium weight of 325 kg (±20), between 28 and 30 months old and the parameters cold carcass height, weight of the thoracic and pelvic quarters, side cut, loin eye area, thickness of fat tissue and sleek-ness of the meat. The latex ring applied on the ovarian pedicle in Nelore breed heifers did not influence positively the carcass and meat characteristics but the loin eye area, which was favorable to the non castrated ones. Key-words: Bovines, carcass, meat, latex ring, ovary.
