Abstract
A field survey was conducted to characterize local “Baladi” goats in the West Bank, Palestine. A total of 104 flocks were sampled in the Southern, Central and Northern geographical regions. Qualitative and quantitative characteristics were recorded on 104 bucks and 416 does. Significant differences were found between males and females and among regions. The multivariate discriminant analyses were able to identify seven body measures for bucks and eight body measures for does which were significant in discriminating Baladi goat populations from the three regions. For bucks, the squared Mahalanobis distances showed higher differentiation between the Southern and Central regions (11.83) and between the Southern and Northern regions (8.02) than between the Central and Northern regions (4.27). For does, distances were similar (3.05, 2.90, and 3.13 between Southern and Central, between Southern and Northern, and between Central and Northern regions, respectively). Canonical discriminant analyses showed that 81.6% of bucks and 74.1% of does were correctly classified into their geographic areas with highest rates found in the Southern region (96.9% of bucks and 88.3% of does). These results form the basis for the development of future characterization and conservation plans of Baladi goats in Palestine.

الملخص
لقد تم دراسة الصفات الشكلية والمظهرية للماعز البلدي في الضفة الغربية باستخدام المسح الميداني. وكان عدد قطعان الماعز المستهدفة 104 موزعة على مناطق شمال ووسط وجنوب الضفة الغربية. وقد تم دراسة الصفات النوعية و الكمية ل 104 من الذكور و416 من الاناث. وبينت نتنائج الدراسة فروقات معنوية بين الذكور والاناث وبين المناطق المختلفة (الشمال، الوسط و الجنوب). وقد حدد تحليل multivariate discriminant analysis سبع صفات في الذكور وثمان في الاناث مهمة في التمييز بين الماعز في المناطق المختلفة. وبالنسبة للذكور فقد بين التحليل ان مسافة Mahalanobis كانت اعلى بين المناطق الجنوبية والوسطى (11.8) وبين قطعان الجنوب والشمال (8.02)، مقارنة بين الوسط والشمال (4.27). اما بالنسبة للاناث فقد كانت المسافات متشابهة بين المناطق المختلفة (3.05، 2.90، 3.13 بين الجنوب والوسط، والجنوب والشمال، والوسط والشمال، على الترتيب). كما بين تحليل canonicalان 81.6 من الذكور و74.1 من الاناث في مناطق الدراسة قد صنفت بطريقة صحيحة حسب مناطقها وكان اعلى معدل للتصنيف الصحيح في المنطقة الجنوبية من الضفة الغربية (96.9% للذكور و 88.3% للاناث).ومن هنا، يمكن اعتماد نتلئج هذه الدراسة كاساس لتطوير الخطط المستقبلية والبرامج المتعلقة بتشخيص والمحافظة على الماعز البلدي في فلسطين وتحسينه.
