أجريت تجربة استخدم فيها 150 صوص بلدي بعمر يوم واحد و 150 صوص هجين لحم روس 308 من أحد المفاقس التجارية و ذلك لمقارنة مستويات هرمون النمو الدموية بين الهجين و البلدي السوري غير المحسن. تم توزيع الصيصان إلى ستة مجموعات تناولت خلطة علفية واحدة و تمت رعايتها في نفس الظروف لمدة ستة اسابيع و في نهاية كل اسبوع تم اختيار 6 طيور حيث وزنت و من ثم ذبحت و اخذت العينات الدموية حيث تم تثفيلها على 3000 دورة/دقيقة لمدة 5-10 دقائق و حفظت لحين اجراء التحاليل حيث تم تحليل الهرمونات باستخدام كيتات تعتمد على المناعة الأنزيمية.
A total of 300 one day old chicks (150 Commercial broiler chicks,150 local Syrian chicks) were raised for 6 weeks in order to measure blood concentration of Growth hormone ,There were 2 treatments 3 replications for each. At the end of every week 6 birds were weighed and bled in order to examine growth hormone.

A total of 300 one day old chicks (150 broiler chicks,150 local
Syrian chicks) were raised for 6 weeks in order to determine the
performance traits (live body weight, FCR, ADG, Breast muscle
yield) There were 2 treatments 3 replication for each .a
nd at the end
of every week all birds were weighed and feed consumption rate
were calculated in order to calculate FCR and ADG Average daily
gain and 6 birds of each group were weighed and slaughtered in
order to determine the breast muscle yield.
In this study, five barley cultivars (Arabi Abiad, improved Arabi Abiad,
Arabi Aswad, Furat 1, Furat 2) from the harvest of 1999 season were used .The
chemical composition, Amino acid content, B-Glucan content, viscosity, cell
wall compounds, and
metabolic energy were determined in two laboratories in
Germany .A metabolism trial was also conducted to study the nitrogen balance,
dry matter, Organic matter, ash, and some other productivity parameters.
Results showed that the influence of barley varieties on chemical composition of
the grains was clearly visible. The crude protein content ranged from 138 for
Furat 1 to 169 gr/Kg dry matter for Arabi Abiad. The difference in starch
content resulted in differences in metabolic energy Values from 12.4 for Furat 1
to 13.3 MJ/Kg dry matter for Arabi Aswad. The food assimilation trial showed
that the varieties Arabi Aswad gave the best productivity parameters, and the
crude protein content did not adversely affect the nitrogen balance in all the
barley varieties meald, but it was the lowest for the Arabi Aswad variety meal
(p <0.05). There were no significant differences in dry matter and organic
matter digestibility for diets containing Arabi Abiad, Furat 1 and Furat 2.
hybrid commercial chicks (Hubbard Flex) were A total of /450/
reared from 1 to 42 days of age. Chicks were distributed into five
groups; each group contained 90 birds within three replicates. Five
diets were used; the first was the traditional die
t (control group) and
the others differed in the growth promoters added and were as
following: nutritional antibiotic (Lincomycin) for the second group,
probiotic (Bacillus subtilis) for the third group, prebiotec (manna
oligosaccharide) for the forth group and finally a mixture of organic
acids for the fifth group.
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).
This research aims to assess and study the evolution of broiler breeding in Syrian
Arab Republic in general and in Syrian Coast and Lattakia Governorate particularly, in
period between 2003 – 2012, and account of production costs for all stages of
broiler
breeding according and analyze these costs, and economical evaluation of production
broiler by using some economic indicators, and clarifying the impact of crisis in Syria the
process of broiler breeding and production in Lattakia Governorate, by comparing the
prices and costs befor and after the crisis.The research shows the production efficiency for
table chicken breeding in Lattakia Governorate amounted to /1.85/ in year 2010, and /1.20/
in year 2014, while the economic efficiencyreached /1.72/ in year 2010, and /1.09/ in year
2014, the return of capital period was 1.3 years in 2010, then it became 9.8 years in 2014.
