Summary: | This study was conducted aiming at measuring the performance and behavior of beef cattle surgically castrated, immunocastrated or non-castrated, finished at 18 months old in Aruana pasture and with energy supplementation. Thirty-nine male bovines with an initial average body weight and age of 284.1 ± 31.4 kg and 14 months old, respectively, were used. The bromatological composition analysis and productive parameters of the pasture did not differ between treatments. The performance of young cattle was not changed by the sexual condition. When evaluating the agonistic behavior, the non-castrated bovine presented a higher number of activities, such as threats and fights, in relation to those immunocastrated. The time spent on the feeder by non-castrated young cattle (56.20 minutes) was higher than that observed for surgically castrated or immunocastrated (41.43 and 32.38 minutes, respectively). The combination between the correct management of Aruana pasture and use of supplementation showed to be promising for finishing bovines. Both surgically castrated and immunocastrated steers demonstrated to be equivalents in the performed evaluations. Therefore, if the farmer chooses castration, the use of immunocastration is suggested. This practice is less invasive, preserves animal welfare more than surgical castration, and has a lower cost. |

Foram utilizados trinta e nove bovinos machos, com peso corporal e idade iniciais médios de 284,1 ± 31,4 kg e 14 meses, respectivamente. A análise da composição bromatológica e os parâmetros produtivos da pastagem não diferiram entre tratamentos. O desempenho dos novilhos não foi alterado pela condição sexual (P > 0,05). Ao avaliar o comportamento agonístico, verifica-se que os não castrados apresentaram maior número de atividades, como ameaças e brigas, em relação aos imunocastrados. O tempo de permanência no comedouro dos não castrados (56,20 minutos) foi superior ao detectado para castrados cirurgicamente ou imunocastrados (41,43 e 32,38 minutos), respectivamente. A combinação entre o correto manejo da pastagem de Aruana e o uso de suplementação se mostrou promissora para a terminação de bovinos. Quando compara-se os novilhos castrados cirurgicamente e os imunocastrados ambos demostraram ser equivalentes nas condições do presente estudo. Portanto, se o produtor optar pela castração sugere-se a imunização contra o fator de liberação de gonatrofinas. Essa prática é menos invasiva, preserva o bem-estar animal mais do que a castração cirúrgica e tem menor custo.UEL2018-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3110510.5433/1679-0359.2018v39n6p2565Semina: Ciências Agrárias; Vol. 39 No. 6 (2018); 2565-2580Semina: Ciências Agrárias; v. 39 n. 6 (2018); 2565-25801679-03591676-546Xreponame:Semina.
