Foram avaliados os efeitos do anel de l芍tex aplicado no ped赤culo ovariano de bezerras da ra a Nelore, no p車s-operat車rio, desempenho e caracter赤sticas de carca a, utilizando-se 23 animais, 8 meses de idade e peso m谷dio de 130 kg, distribu赤das em dois grupos. O grupo I foi constitu赤do por 11 bezerras, nas quais se empregou o anel de l芍tex, e o grupo II composto por 12 bezerras n o-castradas. O anel de l芍tex foi aplicado no ped赤culo ovariano, por meio de abordagem via flanco. No p車s-operat車rio avaliaram-se poss赤veis complica es, ganho de peso m谷dio di芍rio (GPMD), rendimento de carca a, peso vivo emjejum e peso da carca a quente. O procedimento cir迆rgico, de f芍cil execu o, mostrou-se eficaz na supress o do estro. Um animal (9%) apresentou deisc那ncia parcial de ferida. O GPMD do GI foi de 0,308 kg e do GII de 0,311 kg. Animais pertencentes ao GI apresentaram 53,61% e os do GII 52,82% de rendimento de carca a. The effect of latex band at the ovarian pedicle on postoperative, carcass performance and quality was evaluated in 23 Nelore breed heifers, eight-month-old and 130 kg of average weight. They were allocated in two groups: Group I was constituted of 11 heifers with latex band, and Group II was constituted of 12 non-castrated heifers. The latex ring was applied at the ovarian pedicle viaan incision in the flank. On postoperative, potential complications were evaluated, as well as average daily weight gain (ADWG), muscle conversion, body weight after fastening and body weight at the time of inspection. The surgical procedure was executed without complications, and proved to be effective for suppressing estrous. One of the animals (9%) presented partial dehiscence on the wound. The ADWG of GI was 0.308 Kg, and GII was 0.311 Kg, outlining that the animals from GI presented a numerically higher meat gain.
