ABSTRACT A study was conducted to determine the impact of crating density and transportation distance on losses and physiological response of broilers during the winter season. For this, ROSS-308 broilers were crated at three densities (i.e., 10, 12, and 15 birds/crate) in plastic crates and transported in three distances (i.e., 80, 160, and 240 km) during the winter season at 3.6 - 9.5ºC temperature and 63.3 - 78.8% relative humidity. Results showed that body weight loss increased significantly with the increase in transportation distance and decrease in crating density, whereas dead on arrival, physical injuries and bruises were not different among different transportation distance and crating density treatments. Significant reduction in carcass and... |

ABSTRACT Present study evaluated carcass and meat quality attributes of broilers, broiler breeders and Aseel chickens. Sixty birds from each chicken genotype (broiler, broiler breeder and Aseel chickens; five-wk-old broilers and 60-wk-old Aseel chickens and broiler breeders) were evaluated. Birds were maintained under similar environment for 21 days, and then slaughtered to analyze their carcass qualitative and organoleptic characteristics. No carcass yield differences were detected among genotypes. Aseel chickens had heavier neck, followed by broiler breeder and broiler (p<0.0001). Higher liver (p<0.0001), intestine (p<0.0001), ribs and back (p=0.0014) yields were obtained in broilers than in broiler breeders and Aseel chickens. Females showed... |
