| Abstract | ||||
| The present study aimed to improve the body weight in the Alexandria chickens by selection for the skeletal traits of the high breast width, breast length and leg length at eight weeks of age. 2500 birds at a day of hatch were obtained from 5 consecutive hatching weekly hatches were taken for one generation. The results of this study showed that the overall means for Body weight at four, eight and twelve weeks (BW4), (BW8) and (BW12) were (204.699 and 190.02 g.), (718.559 and 610.20 g.) and (1289.99 and 1049.002 g.) for males and females,respectively. This results showed that the differences among line were highly significant (P≤ 0.01) in selected line than control line in BW8 and BW12..Also, the overall means of shank length (SL8), breast length (BRL8) and breast width in eight weeks of age (BRW8) were (6.81and 6.38 cm), (11.85 and11.23 cm) and (11.24 and 10.78 cm) for males and females, respectively. The selection for the skeletal traits in Alexandria chickens in eight weeks of age showed that the differences among line were highly significant (P≤ 0.01) for albumin and Albumin/Globulin ratio in selected line. The analysis results showed that highly significant (<0.0001) positive correlation for BW4 with SL8 (0.47), BRL8 (0.41) and BRW8 (0.39),and highly significant(<0.0001)positive correlation for BW8 with SL8 (0.46),BRL8 (0.61), BRW8 (0.498) and highly significant (<0.0001) positive correlation for BW12 with SL8 (0.39),BRL8 (0.46) and BRW8 (0.42),respectively.In conclusion selection for skeletal traits increased body weight in selected line than control line at different ages. | ||||
