| Abstract | ||
| The study was conducted in sheep and goat research station, office of agricultural research at may - November 2010 to evaluate the effect of wool shearing, breeding group and lamb sex on growth traits which include: Body weight, Average Daily Gain (ADG) at 6, 9 and 12 months of age in 120 Awassi lambs. The lambs divided to Two shearing treatments: shorn (60 lambs) and non-shorn (60 lambs), two breeding groups: Turkish Awassi (60 lambs) and Local Awassi (60 lambs) and two lams sex: male (60 lambs) and female (60 lambs). The lambs reared under semi-intensive production System, with good feeding, good disease control, and suitable housing were provided. The results showed that shearing treatment affected significantly (P<0.05) in growth traits at 9 months. Shorn lambs surpassed non-shorn in body weight (40.23 compared with 39.58 kg) and ADG 6-9 months (81.48 compared with 72.77 gm/day). No significant effect was found at 6 and 12 months of age. Breeding groups affected significantly (P<0.01) in body weight, Turkish Awassi surpassed local Awassi at 6, 9 and 12 month (33.33, 40.60 and45.95 compared with 32.67, 39.18 and 44.21 kg respectfully). Turkish Awassi significantly (P<0.01) surpassed local Awassi in ADG at 6- 9 months (80.74 compared 72.41gm/days) and at 6-12 month (70.12 compared with 64.23 gm/day). No significant effect was found in ADG at 9-12months of age. Lamb sex affected significantly (P<0.01) in body weight, male lambs surpassed female lambs 6, 9 and 12 month (33.55, 40.16 and 46.05 compared with 32.45, 39.16 and 44.10 kg respectfully). Turkish Awassi significantly (P<0.05) surpassed local Awassi in ADG at 6- 9 months (78.52 compared with 74.63gm/day), at 9-12 month (59.96 compared with 55.16 gm/day) and at 9-12months (69.54 compared with 64.81gm/day). It was concluded that shorn lambs in hot season were improve body weight and ADG in both in Awassi lambs at 6-9 months and Turkish Awassi had higher body weight and ADG compared with Local Awassi at 6-12 months. | ||
