Influência de grupos genéticos e de níveis de energia sobre características de carcaça de frangos de corte

Abstract: RESUMO -Este estudo foi realizado para avaliar a diferença entre grupos genéticos e efeitos de dietas com diferentes níveis de energia metabolizável para frangos de corte. O desempenho e a qualidade da carcaça de sete grupos genéticos (M 1 C 1 , C 1 C 1 , C 2 C 2 , M 1 C 2 , C 2 F 1 , C 1 F 1 e M 1 F 1 ) de frangos de corte, obtidos a partir do cruzamento entre dois genótipos desenvolvidos pela UFV (M 1 e F 1 ) e de duas das principais marcas comerciais (C 1 e C 2 ), foram determinados. As aves foram distribuí… Show more

“…Body weight gain for males was significantly higher than females in all further determinations. Lana et al (2000) and Viana et al (2000) found similar results, with higher average body weight for males of broiler strains at 42 days old. et al (2005) report that the effect of the sex on the weight of the birds is usually observed in broilers and that the difference tends to increase with advancing age, whereas in the case of slow-growing birds, which are slaughtered at higher ages, this feature can generate a greater uniformity of lots.…”
