RESUMO

The preslaughtering management conditions including transportation from farm to the slaughterhouse may represent significant economical losses to poultry meat industries due to the injuries affecting their meat qualities. These injuries can be either through physical origin which influence carcass presentation or physiological and/or biochemical origin resulting on the PSE (Pale, Soft, Exudative) or DFD-like-meat (Dark, Firm, Dry) formation. The objective of this work was to investigate the broilers transportation from farm to slaughterhouse on the occurrence of PSE- and DFD-like-meat in a commercial plant. This experiment was conducted in two phases using 900 samples of breast fillets meat (Pectoralis major) in each phase. It was estimated at the first phase the occurrence of PSE- and DFD-like- meat of transporting distances of 4.0, 20.0 and 62.0 km. At the second phase this estimation was carried out in samples with water shower just after truck loading while in the farm at the transporting distances averaged of 3.0, 8.0 and 68.0 km. Meat samples were collected 24h post mortem and analyzed for pH and color values (L*, a* e b*) through the CIELAB system and related them to the meat abnormalities as PSE and DFD-like- meat. Results indicated that at first phase the averaged transportation distance of 20 km showed higher occurrence of PSE meat while the distance of 4 km presented higher incidence of DFD-like meat. At the second phase with the use of water shower before transportation there was lower occurrence of PSE meat at the distance of 68.0 km and at shorter transportation distances there was an increase of PSE meat. Finally, this work demonstrated that the conditions for long distances the water shower resulted in an improvement of climate micro-environment in the birds transporter lorry.
