نُفذت التجربة على 20 حملاً ذكراً من أغنام العواس، متوسط أعمارها شـهران و متوسـط أوزانهـا 08.22 ± 25.1 كغ. وزعت الحملان عشوائياً في مجموعتين بمعدل عشرة حملان فـي كـل مجموعـة، سمنت حملان هاتين المجموعتين في حظيرة نموذجية؛ حيث كانت ظروف الإيـواء و الرعايـة متماثلـة، غُذيت الحملان بصورة حرة مدة 77 يوماً، على عليقتين متزنتين و متماثلتين بمحتواهما مـن البـروتين و الطاقة، إلا أنهما مختلفتين بشكل تقديمهما: قُدمت الخلطة العلفية بشكل مجروش للمجموعة الأولى مـن الحملان و عدت شاهداً، أما حملان التجربة (المجموعة الثانية)، فقُدمتْ لها الخلطة العلفية السابقة نفسها؛ و لكن صنعت بشكل حبيبات علفية.

This experiment is done on (24) male awassi lamb whish are
divided into four categories: the first category took normal water
and is considered as control group. The other three groups took
water processed with different Magnetic Field : 500, 1500, 2000
**Gauss in a series.
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.
A study conducted at Marj Al Kareem (The Scientific Agricultural Centre
for Researches) in cooperation with Damascus University Faculty of
Agriculture, The target group was Awassi sheep; about 323 ewes, 30 rams of
the age "3-4 years", 424 lambs fo

environmental conditions, and the same health care program.
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.
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.
