Avaliação de desempenho, rendimento de carcaça e qualidade da carne do peito em frangos de linhagens de conformação versus convencionais

Abstract: RESUMO -O trabalho foi conduzido com o objetivo de avaliar o efeito de diferentes linhagens (conformação versus convencionais) sobre o desempenho, rendimento de carcaça e partes, medidas físicas (espessura, largura e comprimento do filé do peito) e qualidade da carne do peito (perda de peso por cozimento, maciez e pH) em frangos de corte com 35, 42 e 49 dias. Foram utilizados 2400 pintos de um dia, distribuídos em um delineamento inteiramente casualizado em fatorial 5x2, com cinco linhagens (conformação A, B e… Show more

“…Moreira et al (2003) evaluated different strains of broilers at 49 days of age, and found that Cobb 500 had feed intake 9% lower compared to Hubbard strain, without differing (p > 0.05) in weight gain. These differences may be associated with the genetic divergence existing among the main commercial genotypes operated in Brazil (Cobb 500, Ross 308 and Hubbard Flex) and with the variations in the pattern and growth curve of broilers, which can alter nutrient intake (Marcato et al, 2010;Veloso et al, 2015).…”

“…However, Hubbard Flex and Ross 308 strains showed better thigh and drumstick yields (p < 0.05) compared to the Cobb 500 strain. Moreira et al (2003) evaluated the main strains of broiler chickens exploited in Brazil (Ross, Cobb and, Hubbard) and found that there is no effect of genotype on carcass yield. However, Fernandes, Bortoluzzi, Triques, Garcez Neto, and Peiter (2013) found higher breast fillet yield (p < 0.01) in Cobb 500 strain compared to Ross 308 and Ross 508.…”
