Resumo: | This study had as objective to evaluate the effect of the handling system and season of the year on the performance and meat quality of broiler chicken. Five hundred twenty-four thousand commercial Cobb 500 chicks were allocated in three different handling systems, during the four seasons of the year. The experimental design was completely randomized, with a 3 x 4 factorial scheme (three types of storage shed and four seasons). The diet was provided by a co-operative system and consisted of rice straw, and the broilers were slaughtered in a slaughterhouse at 43 days of age. Feed intake, weight, daily weight gain and mortality rate were available with data provided by the co-operative system. Carcass defects were also evaluated, and analyses of pH, tenderness and drip loss of meat were determined. The chickens raised in automatic and semi-automatic systems and during warm seasons showed lower carcass yield and worse meat quality (great values of drip loss and acidity, small values of tenderness), and higher rates of carcass defects. Chickens raised in a non-automatic system and during cold seasons showed the best performance, with low mortality rate and the best meat quality. |

Foram estudadas 524.000 aves da linhagem comercial Cobb 500, distribuídas em três galpões com diferentes sistemas de automatização, durante as quatro estações do ano. O delineamento foi inteiramente casualizado, com esquema fatorial 3 x 4 (tipo de galpão x época do ano). Foram utilizadas rações do sistema integrado, cama de palha de arroz, e as aves foram abatidas em um frigorífico aos 43 dias de idade. Foram avaliados os dados de desempenho (consumo de ração, ganho de peso diário, conversão alimentar e mortalidade), com dados fornecidos pelo sistema integrado. Também, foram avaliados os defeitos nas carcaças, e análises de pH, maciez e perda de água da carne. As aves criadas nos sistemas automatizado e semiautomatizado, e nos períodos mais quentes do ano, apresentaram menor rendimento de carcaça e piores características de qualidade de carne (maior perda de peso, menor maciez e maior acidez), e maior incidência de defeitos nas carcaças. As aves criadas no sistema não-automatizado e nos períodos mais frios apresentaram melhor desempenho, com menor índice de mortalidade e melhor qualidade da carne.Editora da Universidade Estadual de Maringá2010-04-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campo e laboratorialapplication/pdfapplication/pdfapplication/mswordapplication/mswordapplication/mswordapplication/mswordapplication/mswordapplication/pdfapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/724110.4025/actascianimsci.v32i2.7241Acta Scientiarum.
