استخدم في التجربة ١٥ حملا ذكرًا من سلالة أغنام العواس، ُفطمت بعمر متوسطه ٦٥ يومًا، و بلغ متوسط أوزانها ٢٥,٧ كغ. وزعت الحملان عشوائيًا في ثلاث مجموعات، و سمنت في ظروف إيواء و رعاية متماثلة. أضيفت اليوريا إلى علائق المجموعات الأولى (الشاهد) و الثانية و الثالثة بنسبة ٠%, 1%, ١,٥ % على التوالي. غذيت الحملان بصورة حرة لمدة ٩٠ يومًا ، و وزنت حملان كل مجموعة ، أسبوعيًا و بشكل إفرادي، وفي نهاية التجربة ذبحت ثلاثة حملان من كل مجموعة اختيرت عشوائيًا.

This study was conducted in privatefarm, using a group of 24 Kids.
the kids were from a twin born and selected directly after weaning.
The Kids were randomally divide into 4 groups and subjected to
similar environmental and nutritional conditions.
The adopted hygienic programme was implemented.
Thirty weaned Awassi lambs (٧٥ days old), reared in the metabolic unit at
the College of Agriculture, University of Damascus, were randomly divided into
٥ groups to study the effect of consumed crude protein level available in the
rations on the daily gain rate, live body weight and the food converting rate.
نفذ البحث على ١١٢٥ صوص فروج من الهجين (لوهمان)، وزعت الصيصان إلى ست مجموعات،
استمرت فترة التسمين حتى عمر ٤٩ يومًا، أضيفت اليوريا إلى خلطتي المرحلتين الثانية (من عمر ١٥
٣٥ يومًا) و الثالثة (من عمر ٣٦ ٤٩ يومًا) من التسمين بالنسب المئوية المبينة بجانب كل مجموعة
على التوالي.
The research experiment was carried out during the 2007, 2008 and 2009
seasons on grape variety Al- Helwani (10 years old) to study the effect of NPK
fertilization rates and the triple superphosphate (T.S.P) application method on
some fruits chara
cters.Three fertilization NPK rates were used, rate 1
(75:25:50) kg/ ha, twofold and fourfold of rate 1, in three replicates in addition
to control. The application of (T.S.P) was on soil surface and at 30 cm depth.
The results showed significant increase of the total soluble solids (TSS), pH and
vitamin C compared to control. while the content of TSS in juice increased by
40.9%, 44.6%, 50.3% in the three rates, respectively, compared to control, pH
increased from 5.45 in control to 5.92; 5.89; 5.73 in the three rates,
respectively, in turn, significant decrease in total acidity (TA) was noted by
15.3, 11.1 and 42.8%, in the three rates, respectively, compared to control.
ASignificant increase of (TSS) by 2.5% and vitamin C by 10 % in deep T.S.P
application compared to the surface application, on the other hand, (TA)
decreased significantly by 4.2%, while, there was no significant differences in
pH, in both treatments.
The research was conducted on 25male lambs of Awassi
sheep to compare the effect of using different levels of whole
cotton seeds(WCS). The experiment extended for 70 days,
experimental units were rested, then left for an adaptation period of
10 days, during the adaptation period, the animals were housed in
one pen, in the end of the adaptation period, the lambs were
individually weighed, then divided according to live weight into six
equal groups of an average weights (24-25) kg each.
