| 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... |

| ABSTRACT The present study evaluated different selection strategies to improve the growth performance and carcass traits of Japanese quails. To this end, 540 Japanese quails previously selected for high body weight at three ages (10, 12 and 14 weeks) from four close-bred flocks (Major, Kaleem, Saadat and Zahid) were subjected to three selection strategies: pedigree-based, mass selection or random-bred (controls). For pedigree-based selection, 108 birds (4 close-bred flocks × 3 age groups × 9 replicates × 1 bird each) with full pedigree and selected for high body weight were used, whereas in mass selection 324 birds (4 close-bred flocks × 3 age groups × 9 replicates × 3 birds each) with high body weight were selected to be the parents of next generation.... |

| ABSTRACT The study was planned to evaluate the effect of different naked-neck (NN) chicken genotypes and breeder ages on the growth performance of their progenies. A total of 126 chicks, from two breeder ages and three NN varieties, were reared up to 20 weeks of age. A randomized complete block design in factorial arrangement, with six treatments of seven replicates of two females and one male each, was applied. Treatments consisted of three NN varieties (light brown, black, and dark brown) and two breeder age groups (45 and 55 weeks old). Growth performance (body weight gain, feed intake and feed conversion ratio) were evaluated. Higher feed intake was observed in both the male and female progenies of 55-week-old compared with 45-week-old breeders. Light... |

| 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... |
