“…The birds in the 240 km transportation treatment had the longest exposure to heat stress, which increased drip loss, decreased muscle water contents, and increased toughness of the meat ( Lu et al , 2010 ). Studies have reported a positive relation between muscle water contents and meat tenderness ( Silva et al , 2011 ). Therefore, the decrease in intermuscular water content may result in increase in the shear force required to cut meat.…”

The objective of the study was to investigate the effect of transportation distance and crating density on broiler meat quality during hot and humid weather. Breast meat samples were collected from broilers (Ross-308) after transportation for 80, 160, and 240 km at crating densities of 10, 12, and 15 birds per crate. The broilers were transported in plastic crates of 0.91×0.55×0.31 m (length×width×height) in summer at an ambient temperature of 27.2-33.6 ºC and relative humidity of 52.7-62.9%. The birds were then slaughtered, and the meats' physicochemical characteristics, marination and cooking attributes were measured. Meat pH at 2 hours (h) postmortem (PM) was significantly higher in birds transported for 80 and 160 km compared to those transported for up to 240 km, while meat pH at 24 h PM was higher in birds transported for up to 160 km compared to the other treatments; however, no effect of different crating densities on meat pH and drip loss was observed. Meat losses such as drip loss, thaw loss, cooking loss in raw and marinated breast, and meat shear force were significantly higher in birds transported for up to 240 km compared to the other treatments. An increase in crating density above 12 birds per crate also increased thaw loss, whereas crating density of 12 birds per crate and higher increased cooking loss and meat shear force. Meat lightness also increased significantly with the increase in transportation distance above 160 km and crating density above 12 birds per crate. In conclusion, transportation of broilers for more than 80 km with crating density higher than 12 birds per crate during summer was associated with severe losses in yield and deterioration in physical appearance and functional characteristics of meat.

The study aimed to examine the meat quality of chickens from a dual-purpose cross and its parent lines. The trial was conducted in the experimental poultry farm of the Institute of Animal Science-Kostinbrod, Bulgaria. The dual-purpose chickens were obtained by crossing female layers (Line L) and dual-purpose cocks (BB, based on Bresse Gauloise). At the age of 9 weeks the male chickens from the parent lines and the dual-purpose cross were slaughtered. Six chickens of each genotype were subjected to breast and thigh meat quality analysis. The crossbred chickens tended to have lower pH in breast but the values of this parameter were higher in their thighs. The BB line showed the poorest water-holding capacity (WHC) in both breast and thigh meat cuts. This line and the crossbreed showed lighter meat compared to the L line. Except the ash content of the breast and thigh meat that was higher in the BB line, the proximate composition did not differ between the examined lines and their cross. The L and dual-purpose chickens tended to have higher intramuscular fat (IMF) but lower protein in thigh meat than the BB line. The correlation analysis revealed clear relationships between the meat quality traits and the proximate composition, however they differed for the breast and thigh meat.

Effects of season and distance during transport on broiler chicken meat

et al. 2017

This research aims to evaluate the microclimate of commercial loads of broiler chickens at different distances in the summer (rainy) and winter (dry) seasons and their effects on meat quality. Twelve broiler loads were monitored with a total of 24 crates per load. Data loggers were used to record temperature and relative humidity. The experiment followed a completely randomized design with 48 treatments in a factorial scheme (2 seasons: rainy and dry) x 2 (distances: short and long) x 12 (positions), with 3 replicates per experimental group. In the rainy season, meat quality was influenced by transport distance. For longer distances, it recorded the highest enthalpy comfort index (ECI), suggesting a tendency of dark, firm, and dry meat (DFD-like) and lower cooking losses (CL). The lowest ECI was recorded during the transport in dry season. Broiler chickens transported and slaughtered in the winter presented meat pH and L* (lightness) classified as "normal," but with higher cooking losses. For the shear force (SF), the seasons and distances had no significant influence on tenderness of the meat. Regarding the crate positioning in the load, no effect was observed during transport on this variable, given the meat quality characteristics of pH, L*, CL, and SF. These results suggest that the distance and the seasons present more influence on broiler meat quality than crate position in the truck.
