نفذ هذا البحث في مركز فديو لبحوث الإنتاج الحيواني التابع لكلية الزراعة في جامعة تشرين مع بداية فصل الصيف من عام 2010 بهدف دراسة إمكانية تحسين أداء فروج التسمين تحت ظروف المنطقة الساحلية و زيادة المردود الاقتصادي . اظهرت نتائج البحث أن إضافة مسحوق الحبة السوداء و الزعتر بمقدار 0.5% إلى العليقة منخفضة الطاقة أدى إلى زيادة متوسط الوزن الحي بعمر ( 9 - 28 ) يوماً , بلغ 864.9 غ (G3) بالمقارنة مع الشاهد ( بدون إضافة ) و الذي بلغ متوسط الوزن الحي عنده (850.7) غ لنفس العمر كما بلغ معامل التحويل الغذائي FCR 2.63 عند المجموعة G1 مقارنة مع 1.89 عند الشاهد C كما أظهرت نتائج البحث أن إضافة 0.25% من مسحوق الحبة السوداء و الزعتر أدى إلى زيادة في متوسط الوزن الحي و الذي بلغ 848.6 غ مقارنة مع افراد (G1 670.7) غ كما بلغ معامل التحويل الغذائي FCR 1.96 عند المجموعة G4 بإضافة (0.25% من مسحوق الحبة السوداء و الزعتر ) مقارنة مع 2.63 عند مجموعة G1 .
This research carried out in the Video Center for Research on Animal Production of the Faculty of Agriculture at Tishreen University with the beginning of the summer of 2010 in order to study the possibility of improving the performance of broiler chickens under the conditions of the coastal area and increase economic returns. Search Results showed that the addition of black bean and thyme powder by 0.5% to a low-energy diet led to increased average live weight of age (9-28) days totaled 864.9 g G3)) compared to the control (without the addition), which amounted to an average live weight has 850.7) g) of the same age FCR feed conversion ratio stood at 2.63 at the group G1, compared with 1.89 when the Control CSearch results also showed that the addition of 0.25% of the black bean and thyme powder led to the live weight increase of 848.6, compared with 670.7 members G1) g) FCR feed conversion ratio stood at 1.96 at the G4 Group added (0.25% of the black bean powder and thyme), compared with 2.63 at the G1 group.

Antimicrobial compounds have been used for decades in poultry diets to increase
performance and decrease morbidity particularly in broiler chickens. However, consumer
pressure related to the potential development of antibiotic-resistant bacteria ha
s resulted in
the development of non-antibiotic feed additives that may also improve broiler erformance.
In recent years, aromatic plants and their extracts have received attention as growth and
health promoters. Such products have several advantages over commonly used commercial
antibiotics since they are residue free and they are also, generally recognized as safe and
commonly used items in the food industry. The antimicrobial properties of medical plants
and their extracts have been widely reported because they consist of many active
ompounds such as carvacrol, eugenol,which partition lipids in the bacterial cell wall and
mitochondria, disturbing the structures and rendering them more permeable.
Generally,medical plants are slightly more active against Gram-positive than Gramnegative
bacteria. Medical plants are well known for their antioxidant activity and show a
considerable effect on increasing the antioxidant capacity of chicken meat because they
consist of many of active compounds such as tocopherol, carvacrol. Spices or their active
principles have been reported to stimulate digestive secretions such as lipase, amylase and
proteases.because they consist of many active compounds such as anothol, eugenol.
Variable effects of medical plants and their extracts on the productive performance of
broiler have been reported. The majority of experimental results indicate improved body
weight gain or final body weight and feed conversion ratio.
The effect of adding two organic acids(formic acid, acetic acid). with broiler drink
water was tested to evaluate their efficacy on the their performance and health Groups
treatment consumed amounts of feed that are greater than the control but for
The results in
the six trials showed superiority of the feed conversion ratio and the final weight of broiler
in the two groups that was added complex to its drink water, compared to the control with
significant differences at 0.05.
There was no significant difference between the replicates of each trial on its own
while the results of laboratory parasite testing of samples litter showed that the number of
oocysts in the litter was the lowest in the treatment groups with significant differences
compared to the control. It was noted that the number of oocysts in litter increased until a
certain age and then began to decline.
The results also showed reduced mortality in all trials with treatment and there were
no significant differences in treatment groups compared to the control.
Aiming to develop the growth, to decrease antibiotic and increase
immunity of poultry, propolis and garlic powder was used in
feeding of broiler chicken by adding it in the form of dry powder .
The research was carried out on Hubberd hybrid which they are
locally existed. Birds were divided into four groups (control and
three experiment groups).
Coccidiosis is one of the major parasitic diseases of poultry . The disease has s great economic impact in poultry due to resistance of the organisms to anticoccidial drugs.
The research was carried out using 1728 broiler chicks (shifer starbro
hybrid), They were divided into eight groups, each one consists of three
replicates with 72 birds in every repetition .The birds of all repetitions were
fattened until 49 days
in separate pen of open type walk ,and on deepbedplate
.All conditions of placement, rearing and feeding were the same for all birds of
repitition in different groups.
