أجريت تجربة استخدم فيها 150 صوص بلدي بعمر يوم واحد تم جمعها من ريف حماة و 150 صوص هجين لحم روس 308 من أحد المفاقس التجارية و ذلك لمقارنة الكفاءة الإنتاجية و نسبة لحم الصدر مع البلدي السوري غير المحسن. وزعت الصيصان إلى ستة مجموعات تناولت خلطة علفية واحدة تمت رعايتها في نفس الظروف لمدة ستة اسابيع و في نهاية كل اسبوع تم اختيار 6 طيور حيث وزنت و ذبحت و اخذت نسبة وزن الصدر.
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 .and 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.

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.
The influence of Red Paprika and Local Safflower in the diets on yolk color
was studied in two experiments of ٨ and ٥ weeks using ٩٠ and ٢٤ laying hens,
respectively; Loghorn hybrids of Lohmann brown and Hy- Lain Brown strain,
were used.
In the f
irst experiment, yellow corn was substituted totally by rye and wheat
and ٤ different amounts of paprika or safflower were tested (٠,٢, ٠,٣, ٠,٤ and
٠,٥٪). In the second experiment the effect of sweet red paprika or hot red
paprika in the diet (٠,٥٪) on yolk color or some of production parameters was
studied.
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.
Milk production and composition were studied on (٣٠) yearlings of
improved Awassi sheep during their first lactation, from ١٩٩٧ to ١٩٩٨ at the
Faculty of Agriculture, Damascus University.
At the beginning of experiment the animals were ١٤ to ١٦,٥ months old and
their body weight was ٤١,٥ kg.
The research aims to study the determinants of purchase to the consumers of chicken
meat in the province of Latakia, and see how it affected the consumer when making a
purchase decision, respondents were surveyed (500) the consumer, was the distrib
ution of
a questionnaire allocated for this purpose.
Use the statistical and analytical method for the study and analysis of the data, which
used randomized complete block design, and testing of F in accordance with the SPSS
statistical program, the research found a range of results, including:
• purchasing decision influenced by a variety of factors: the level of consumer
income - Product Specifications - the price of chicken meat - other meat prices - the views
of friends.
• Low impact of consumer life and the views of the seller and the Declaration on the
purchase decision process.
