Broiler transportation conditions in a Brazilian commercial line and the occurrence of breast PSE (Pale, Soft, Exudative) meat and DFD-like (Dark, Firm, Dry) meat

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)

The effect of management of transport and lairage conditions on broiler chicken breast meat quality and DOA (Death on Arrival)

“…Journey maneuvers from the farm to the slaughterhouse, such as showering the birds at the farm, heat, vehicle acceleration, vibration, movement, impact, food and water deprivation, social disruption, and noise, are especially important (Mitchell andKettewell 1998, Simões et al, 2009a, b). In fact, heat stress during truck transport is one of the main causes of DOA and PSE development (Mitchell and Kettewell 1998, Langer et al 2009, Simões et al 2009a. As reported by Warriss et al (1992) and Petracci et al (2006), one of the main causes of DOA is the management during transport and that thermal stress leads to the increased mortality percentage.…”

Functional properties of PSE (Pale, Soft, Exudative) broiler meat in the production of mortadella

“…Transport conditions during the trip from the farm to the slaughterhouse, such as showering at the farm, heat, acceleration, vibration, movement, impact, food and water deprivation, social disruption, and noise, are especially important (Mitchell and Kettewell, 1998). In fact, heat stress during truck transport is one of the main causes of PSE (Mitchell and Kettewell, 1998, Langer, et al, 2009. PSE meat occurs around the world: in the USA, Woelfel et al (2002) reported that PSE occurs in 30-50% of broiler meat and in Brazil, PSE was found in approximately 22% of broiler meat (Soares et al, 2003).…”

Electrical Water Bath Stunning of Broilers: Effects on Breast Meat Quality

“…The Cobb mixed-sex broilers, aged 44 days were routinely prepared for slaughter after a 6-h fast prior to harvesting. The birds were manually harvested with 8-10 animals per cage, and received an overall shower mist before truck transportation (Simões et al, 2009, Langer et al, 2010. During transportation, the average speed was 60 km/h and the distance from the farm to the commercial slaughterhouse was 40 km.…”
