ABSTRACT
The objective of this work was to investigate the effect of road transportation conditions on the occurrence of broiler PSE-(Pale, Soft, Exudative) and DFD-like (Dark, Firm, Dry) meats in the Brazilian commercial slaughterhouse plant. Samples of Pectoralis major m from 47-day-old broilers of commercial lineage were analyzed. The results indicated that water-bathing birds just before journey over 3.0km promoted the occurrence of 46.0 percent of PSE and 4.0 percent of DFD-like meat, while birds under non-water bathing conditions presented 14.7 and 2.0 percent, respectively. For a distance of 68.0km, the occurrences of PSE-and DFD-like meat were 44.0 and 0.0 percent under water bathing conditions, and 52.0 and 0.0 percent without water bathing, respectively. Water bathing at the farm was a critical manoeuvre for increasing the unfavourable truck microenvironment for short journey, whereas conversely for longer journey it was less stressful influencing the broiler breast meat quality.
RESUMO
O objetivo deste trabalho foi investigar o efeito das condições do transporte na ocorrência das carnes PSE (Pale, Soft, Exudative) e a-DFD (Dark, Firm, Dry) de frangos nas condições brasileiras em uma planta de um frigorífico comercial. Foram analisadas amostras de peito de frango (Pectoralis major m.) da ave de 47 dias de linhagem comercial. Os resultados indicaram que o banho dos frangos imediatamente antes da viagem de 3,0km promoveu a ocorrência de 46,0 por cento de PSE e 4,0 por cento de a-DFD enquanto que frangos sem banho apresentaram 14,7 e 2,0 por cento, respectivamente. Para uma distância de 68,0km, a ocorrência de carnes PSE e a-DFD foram 44,0 e 0,0 por cento, respectivamente, de aves que sofreram banho e 52,0 e 0,0 por cento sem banho, respectivamente. O banho ainda na granja foi uma atividade crítica aumentando as condições desfavoráveis no microambiente do caminhão para curtas distâncias e contrariamente para distâncias longas foi menos estressante influenciando na qualidade do peito do frango.
