Ganho de peso e características de carcaça de bovinos Nelore castrados ou não-castrados terminados em confinamento

Abstract: RESUMO -Objetivou-se avaliar o ganho de peso e as características de carcaça de bovinos Nelore, castrados ou não-castrados, terminados em confinamento. Utilizaram-se 36 animais com 24 meses de idade e peso vivo médio inicial de 445,30 (não-castrados) ou 449,57 kg (castrados aos 400 kg de peso corporal of rigor mortis is also similar between and non-castrated and castrated animals. Non-castrated and castrated animals have satisfactory carcass weight, but have not fat thickness less than 3 mm, when confined f… Show more

“…This can be evidenced if it is compared the results obtained by Souza et al (2007) and by Marques et al (2007), who, from daytime evaluations observed the time spent with food ingestion by confined crossbred animals of 20, 69 and 87.3 minutes, respectively.…”

“…Smaller losses were observed by Silva et al (2008), who gave sugar cane based diets for confined bovines and found average losses of 1.91% during carcass cooling, with fat cover of 2.64 mm, whereas Fernandes et al (2007) and Brondani et al (2006) obtained averages of 2.11 and 2.40 mm for fat thickness on the carcass. However, those results are considered to be low for market requirement for carcass quality.…”

“…To ensure early finishing, the diet of cattle should contain high energy levels (SILVA et al, 2008). Thus, to achieve the desirable fat scores in regions of low-energy forage, it is necessary to confine the animals and supplement their diets with concentrates.…”

“…Quanto aos rendimentos dos cortes cárneos, apenas a porcentagem do total de carne foi ascendente com o aumento dos teores de óleo de linhaça na dieta, com efeito quadrático para o rendimento do cupim (Tabela 4). Machos castrados obtiveram carcaças mais pesadas em relação às fêmeas (Tabela 2), e essas carcaças são preferidas pelos frigoríficos, por demandar a mesma mão-de-obra e tempo de processamento do que carcaças mais leves (SILVA et al, 2008). Os maiores peso e rendimento do dianteiro, profundidade de carcaça (Tabela 2) e pesos do acém, peixinho, paleta e músculo (Tabela 3) dos machos castrados, estão relacionados com as características de diferenciação sexual, pois, apesar dos animais terem sido castrados aos 15 meses, pode-se observar efeito dessa diferenciação ocasionada, provavelmente, por ação dos hormônios andrógenos que são associados à maior deposição de massa muscular no organismo (McDONALD & PINEDA, 1991).…”
