شملت الدراسة تحليل 204 سجل عائد الى 50 مولود محلي و 154 مولود شامي و لصفات ابعاد الجسم لعمر الميلاد و الفطام لغرض دراسة تاثير بعض العوامل الوراثية واللاوراثية على بعض ابعاد الجسم لدى الماعز المحلي والشامي , اذ بلغ المتوسط العام لعمق البطن و عرض الصدر و عرض البطن و ارتفاع المنطقة الخلفية ومحيط المنطقة الخلفية في عمر الميلاد 15.47 , 5.64 , 5.14 , 34.20 , 31.77 سم على التوالي, وبلغ المتوسط العام لنفس الصفات السابقة في عمر الفطام 27.84 , 9.22 , 10.17 , 52.88 , 54.38 سم على التوالي. لوحظ عدم وجود تاثير معنوي لكل من المجموعة الوراثية و جنس المولود على الابعاد عند الميلاد عدا محيط المنطقة الخلفية اذ لوحظ تأثره بشكل عالي المعنوية (P<0.01) بالمجموعة الوراثية عند الميلاد, بينما كان انحدار جميع ابعاد الجسم لفترة الميلاد على وزن الميلاد عالي المعنوية (P<0.01) وكذلك شهر الولادة اذ كان تاثيره معنوي (5P<0.0) لعمق البطن و عالي المعنوية (P<0.01) للأبعاد الاخرى . لوحظ عدم وجود تأثير معنوي للمجموعة الوراثية في الابعاد عند عمر الفطام باستثناء عرض الصدر اذ تأثر بشكل معنوي (5P<0.0) بالمجموعة الوراثية عند الفطام وكذلك كان الانحدار على وزن الميلاد عالي المعنوية (P<0.01) لجميع الابعاد عند عمر الفطام ولوحظ عدم تاثير جنس المولود عند الفطام على الابعاد لنفس الفترة العمرية . ومن النتائج يمكن الاستنتاج انه توجد مجموعة من العوامل التي لها تاثير على ابعاد الجسم والتي تعد محدد لزيادة النمو من خلال زيادة او نقصان الابعاد الجسمية .
كلمات مفتاحية : ماعز , ابعاد جسمية . عوامل وراثية و لاوراثية .

Abstract
Included analysis of 204 records belonged to 50 Local and 154 Shami kids , for dimensions traits of the body at birth and weaning ages For the purpose of examining the effect of some genetic and genetic factors on some of the dimensions of the body to the local goats and Shami. The overall means of the depth of the hip, chest width, hip width, height of the hip and the girth of the hip at birth age 15.47, 5.64, 5.14, 34.20, 31.77 cm, respectively, and were 27.84, 9.22, 10.17, 52.88, 54.38 cm respectively at age of weaning. No significant effect of both genetic group and kid sex on dimensions at birth, except for the girth of the hip which affected high significantly (P <0.01) by genetic group at birth. While the effect of regression on the birth weight was significantly high (P <0.01) for all-dimensional for a period of birth as well as the month of birth as its impact was significant (P <0.05) of the depth of the hip and the significantly high (P <0.01) for the dimensions of the other . No significant effect of genetic group in dimensions was noted at the age of weaning, except for the Chest width as influenced high significantly (P <0.01). as well as the regression on birth weight was significant (P <0.01) on all dimensions at the age of weaning and did not affect by the sex of kids at weaning on the dimensions of the same age period. It is the results it can be concluded that there are a range of factors that have an impact on the dimensions of the body, which is specified to increase growth through an increase or decrease dimensional physical.
