ABSTRACT One-day old goat kids were separately allocated to three treatment groups; Baladi (n = 56), Shami (n = 47) and Hybrid (n = 25). The LBW and BWG (kg/kid) of the kids were recorded at weekly intervals, and the survivability was calculated at the end of the trial. The results indicated that mean weekly Live body weight (LBW) shows a significant increase (P < 0.05) for both males and females of the three goat breeds tested. The final LBW (12-week-age) of both sexes of Shami goats was significantly (P < 0.05) higher than Baladi and Hybrid. Male goats (15.45 ± 3.65, 17.71 ± 5.23 and 15.96 ± 4.99 kg/kid) had significantly (P < 0.05) higher LBW than their female counterparts (12.52 ± 3.41, 14.92 ± 5.10 and 11.01 ± 2.64 kg/kid) in Baladi, Shami and Hybrid, respectively. Total BWG of Shami goat males and females was higher than Baladi and Hybrid breeds. The total survivability was higher in Baladi (94.64%) than in Shami (91.49%) and Hybrid (80.00%). In conclusion, the present findings indicated that production performances of goats were considerably affecting by their breed and sex, and Shami breed had supported comparatively better growth responses. Therefore, Shami goat breed might be recommended for more economic and profitable for rearing under good farming management in Jordan.

约旦三种山羊品种生长率和存活率的比较研究

摘要 一天大的山羊孩子被分别分配到三个治疗组;巴拉迪 (n = 56)、沙米 (n = 47) 和混合 (n = 25)。每周记录孩子的 LBW 和 BWG(kg/kid),并在试验结束时计算存活率。结果表明,所测试的三个山羊品种的雄性和雌性平均每周活体重 (LBW) 均显着增加 (P < 0.05)。两性沙米山羊的最终 LBW(12 周龄)显着(P < 0.05)高于 Baladi 和 Hybrid。雄性山羊 (15.45 ± 3.65, 17.71 ± 5.23 和 15.96 ± 4.99 kg/kid) 的 LBW 显着 (P < 0.05) 高于雌性山羊 (12.52 ± 3.41, 14.92 ± 5.10 和 15.96 ± 4.99 kg/kid, 12.61 kg ± 1.61 kg)分别是 Shami 和 Hybrid。沙米山羊雄性和雌性的总体重高于巴拉迪和杂交品种。Baladi (94.64%) 的总生存率高于 Shami (91.49%) 和 Hybrid (80.00%)。总之,目前的研究结果表明山羊的生产性能受其品种和性别的影响很大,而沙米品种支持相对更好的生长反应。因此,沙米山羊品种可能被推荐用于在约旦良好的农业管理下饲养更经济和更有利可图。
