ُنفِّذ البحث في وحدة الهضم في كلية الزراعة (أبي جرش) على ٣٠ رأسًا من حِملان العواس بعد فطامها ( ٧٥ يومًا). وزعت إلى خمس مجموعات بشكل عشوائي، و تم تسمينها في مرحلتين على خلطات علفية مختلفة فيما بينها بنسبة البروتين.
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.

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.
The research was conducted on 24 male lambs of Awassi
sheep to study the effect of using different levels of soya bean
meals(SBM), partially dehulled sunflower meals (SFM) and
partially dehulled cottonseed meals(CSM). 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 three equal groups of an average
(22-25)kg each.
The concentrates was the same for all groups in protein and
energy intake, but the difference was only in percentage of
SBM21%, SFM 20%, and CSM15%.

Two experiments were couducted to study the effect of reducing the level of
animal protein on the carcass quality of broilers. Eight hundred birds used in
the first experiment were divided into ٤ groups and left under ٣ feeding stages.
Four hundre
d birds used in the second experiment were divided into two others
groups and left under two feeding stages.
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.
