تم إجراء البحث في الساحل السوري في ثلاثة مناطق تربى فيها قطعان عرق أغنام العواس و هي مناطق (عرب الملك – دوير الخطيب – بخضرمو) بلغ عدد رؤوس الأغنام فيها (439) رأساً, حيث بدأت التجربة بتاريخ 2/11/2009 على القطعان, و التي خضع منها للدراسة قطيع تم اختياره عشوائياً بلغ عدد (82) رأساً و كان توزيعه على التوالي (33 – 27 – 22) رأس و أخذت القياسات خلال الأيام (30 – 90 – 150 ) من موسم الحلابة و انتهت بتاريخ 4/3/2010. بينت النتائج أن المرحلة الثانية المحددة (90) يوم أظهرت أكبر قياسات للضرع و التي توافقت بين الحد الأعظمي لإنتاج الحليب , و كذلك كان لمواصفات الضرع تأثيراً معنوياً على جميع أشكال الغدد اللبنية (20.01) و أن لمواصفات الحلمة و ترتيب موسم الحلابة و فترة القياس تأثيراً على قياسات الحلمة (20.01) و لم يكن لها تأثير على الطول , و كان لموسم الحلابة و العمر تأثيراً على ارتفاع الضرع عن سطح الأرض (20.001). و تبيّن وجود علاقة ارتباط غير ثابتة بين مواصفات الضرع و كمية الحليب و كذلك علاقة ضعيفة و إيجابية بين كمية الحليب و قياسات الحلمة حسب الترتيب ( r= 0.33, r= 0.49, r= 0.19, r= 0.27).
A research had been made in three areas at the Syrian Cost where Al Awassi race is grown; these areas are (Arab Al Mulk, Dwer Al Khateeb, Bekhdarmow). The number of Al Awassi there reaches to (439) heads. The research was started at 2/11/2009, and a random sample of (82)was selected from each area (33-27-22) in a row, and measured were at the day number (30-90-150) during the season milking, and completed at 4/3/2010. Results showed at the second phase of day (90) a high measurements of udder which meets the maximum standards of milk production, and the udder specification had a significant impact on all forms of the mammary gland (20,01), as well as the nipple specification, order of milking season, and age had impact on the nipple's size (20,01), but not on the length of it, but the season milking and age had effect on udder height above the ground (20,001). Results showed a correlation which is not fixed between the udder specifications and quantity of milk as well as a weak and positive relationship between the amount of milk and nipple measurements in the order of (r=0.33, r=0.49, r=0.19, r=0.27).

The research was conducted on 24 ewes of Awasi sheep. The
animal study were divided into 4 groups each includes six ewes.
The first three groups were injected via variant proportions of
BST hormone ( as serial doses 40 mg, 80 mg, and 120 mg)
dail
y for 2 weeks. The fourth group was considered as control
group. It was measured the quantity of morning milk and
measurement of fat and protein and lactose one time every
week. Tissue specimen was taken from udder to study the
changes of secretive vesicles.
Milk production and composition were studied on (٣٠) yearlings of
improved Awassi sheep during their first lactation, from ١٩٩٧ to ١٩٩٨ at the
Faculty of Agriculture, Damascus University.
At the beginning of experiment the animals were ١٤ to ١٦,٥ months old and
their body weight was ٤١,٥ kg.
The nose plays an important role in diagnosis and in orthodontic and surgical
treatment plan. The aim of this study is to evaluate the relationship between the nose shape and the underlying
hard structures. This study has been done in orthodontic d
epartment / Damascus University.
This study was conducted in Ber Al-Ajam village, on a private farm, with a
group of Awassi sheep (76 ewes) in 2004-2005. A group of 57 lambs were
selected out of single born lambs and divided into two groups according to sex.
Each group was divide
d randomly into sub groups: control and experimental.
At the beginning of the experiment, at three weeks age, there were no
significant differences between the groups of lambs (p > 0.05).
Three hundreds and thirty samples of raw milk and some of the Syrian
dairy products collected during 2002-2003 from different areas of Syria, and
were used to detect the presecne of Listeria in these products.
Results indicated that mainly L. mono
cytogenes and to a lesser degree
L.innocua and L.ivanovii were found in these products. The perecentage of
violating of the Syrian standards was 4 % in raw milk, 0.0% in pasteurized
milk, 2% in white cheese, 0.5% in shinglish and 0.0% in ice cream. And it has
been deterhmined the identity of the isolated bacterial species of Listeria from
the above-mentioned products, where L. monocytogenes was dominant, and to a
lesser estent were L. innocua and L. ivanovii.
