“…Mitchell and Kettlewell (1994) emphasise that the potentially harmful effects of adverse conditions during the transport are not only of political and public concern due to their consequences for animal welfare, but are also of economic importance with respect to increased losses and diminished quality of meat. A correlation between meat quality and exposure to preslaughter stress conditions has been demonstrated by Gregory (1996), Kannan et al (1997), Owens and Sams (2000), Taubert et al (2002), Debut et al (2003) and others. In addition, the stress associated with transporting poultry prior to slaughter has been shown to increase endogenic contamination and consequently aggravate the microbial risk for the consumer of poultry meat (Mengert and Fehlhaber 1996;Mengert et al 1998).…”

Voslářová E., B. Janáčková, L. Rubešová, A. Kozák, I. Bedáňová, L. Steinhauser, V. Večerek: Mortality Rates in Poultry Species and Categories during Transport for Slaughter. Acta Vet. Brno 2007, 76: S101-S108.Transport-related mortality rates were compared for various poultry species and categories where published data are limited. The numbers of broilers, hens and cockerels, turkeys, ducks, and geese transported for slaughter, and the numbers that died during such transport, were recorded from 1997 to 2006 in cooperation with the State Veterinary Administration of the Czech Republic. The mortality rate for individual poultry species and categories was calculated overall, and was also recorded for the following transport distances: up to 50 km, from 51 km to 100 km, from 101 km to 200 km, from 201 km to 300 km, and over 300 km. Transport of poultry for slaughter was accompanied by varying mortality rates depending on poultry species and categories. The highest mortality rates occurred in hens and cockerels (1.013%), followed by turkeys (0.272%), broilers (0.253%), ducks (0.103%), and geese (0.056%). Differences among the mortality rates estimated were highly significant (p < 0.001). Mortality rates highly correlated with transport distance. The lowest mortality rates were for the shortest transport distances: In broilers (0.154%), turkeys (0.164%), and hens and cockerels (0.595%) for a transport distance up to 50 km; and in ducks (0.069-0.111%) and geese (0.021 -0.053%) for transport distances up to 300 km. Highest mortality rates in hens and cockerels (1.892%), turkeys (0.341%), and broilers (0.536%) were observed for transport distances over 200 km, while in ducks (0.147%) and geese (0.253%), highest mortality rates were with transport distances exceeding 300 km. The highest mortality rates for all transport distances were in hens and cockerels, followed by turkeys and broilers. The mortality rate in turkeys for a transport distance up to 50 km was significantly higher than that in broilers. No significant differences were found between mortality rates in turkeys and broilers for transport distances of 51-100 km and 101-200 km whereas, for a distance of 201-300 km and in distances exceeding 300 km, the mortality rates in broilers were significantly higher compared to turkeys. The lowest mortality rates were observed in ducks and geese, with a significant difference between them only for transport distances of 51 to 100 km, where the mortality rate in ducks was higher, and over 300 km, where the mortality rate in geese was higher. When planning the transport of poultry for slaughter, susceptibility to stress induced by transport and transport distance (i.e. the duration of transport) of poultry species and categories should be considered.

“…Long duration transportation has been reported to result in physiological and metabolic changes (Yue et al, 2010;Zhang et al, 2009) and that can affect animal welfare, processing yield and meat quality (Owens and Sams, 2000;Dadgar et al, 2010;Petracci et al, 2010). More importantly, transport stress also causes higher chicken mortality, live weight loss and poor meat quality, which results in substantial economic losses to the poultry industry (Bianchi et al, 2005;Karaman, 2009;Chauvin et al, 2011).…”

A total of 320 male Arbor Acres broiler chickens (28 days old) were randomly allotted to one of the three experimental diets supplemented with 0 (160 birds), 600 (80 birds) or 1200 mg/kg (80 birds) creatine monohydrate (CMH) for 14 days. On the morning of 42 day, after an 8-h fast, the birds of CMH-free group were divided into two equal groups, and all birds of these four groups were transported according to the follow protocol: 0.75-h transport without CMH supplementation (as a lower stress control group), 3-h transport without CMH supplementation, 3-h transport with 600 or 1200 mg/kg CMH supplementation. Each treatment group was composed of 8 replicates with 10 birds each. The results showed that supplementation of CMH for 14 days before slaughter did not affect the overall growth performance and carcass traits of stressed broilers (P>0.05). A 3-h transport decreased plasma glucose concentration, elevated plasma corticosterone concentration, increased bird live weight loss, breakdown of muscle glycogen, as well as the accumulation of muscle lactate (P<0.05), which induced some detrimental changes to breast meat quality (lower ultimate pH and higher drip loss, P<0.05). Nevertheless, supplementation of 1200 mg/kg CMH reduced chicken weight loss, decreased the contents of lactate and glycolytic potential in pectoralis major of 3-h transported broilers (P<0.05), which is beneficial to maintain breast meat quality by reducing the drip loss (P<0.05). These findings suggest that the reduction of muscle glycolysis is probably the reason for maintainance of meat quality by supplementation of CMH in transported broilers.

“…A 3 h transport decreased glycogen contents with an increase in lactate content in broilers breast muscle, accompanied with lower pH 24 h and higher drip loss, so transport induced negative changes on broiler breast meat quality could result from the glycolytic enhancement [30]. Savenije et al, Owens et al and Debut et al also found the similar results of glycogen contents in birds breast muscle [10,28,31]. However, the increasing transport time decreased the glycogen content of biceps femoris muscle, while that of the breast muscle did not change, possibly since the thigh muscle is involved in maintaining balance in the moving vehicle during transport [32].…”

“…This can alter the physiological states of animals and subsequently affect meat quality. Transport stress impacts on parameters of bird physiological responses, like corticosterone (CORT), glucose and creatine kinase (CK) before slaughter [6][7][8] and thus has an effect on meat quality indices such as meat color and water holding capacity (WHC) [9,10]. According to these indicators, we can evaluate the stress level of poultry, so as to improve the management of transport conditions to meet the needs of poultry [6].…”

Transport is unavoidable before slaughter in the poultry industry. The birds may be exposed to various stressors during transport, including birds health condition, fasting, handling, (un)loading, crating density, transport time, vehicle design, trailer microclimate and lairage time. To cope with transport stress, poultry develops physiological responses, which may subsequently affect meat quality and mortality. The paper aims to investigate the effects of transport duration, trailer microclimate and loading density on physiological responses and meat quality of birds. Transport is likely to cause high stress level and energy consumption in poultry according to physiological parameters. The impacts of transport stressors on meat quality are inconsistent or even contradictory. To get consistent results of meat quality following transport, unified measurement methods and the transport conditions are demanded. Furthermore, future research needs to pay more attention to the effects of transport under cold temperature and loading density on poultry to improve their welfare and reduce economic loss.
