أجريت الدراسة في مخبر الأسماك - كلية الطب البيطري – جامعة حماة خلال الفترة الممتدة مابين شهر آذار و شهر أيلول حيث أجريت التجربة تحت ظروف المختبر و تم استخدام خمس مستويات من Ivermectin.
The study was conducted in a fish laboratory in the college of veterinary medicine during the period between the months of March and September. The experiments of this study were performed in laboratory conditions. Five dosage levels of Ivermectin were administered.

The study was conducted at the Breeding and fish diseases
Laboratory - College of Veterinary Medicine were used drug
substance ivermectin concentration of 1% - 50 μg/ kg on the
normal Carps.
This study aimed to investigate the effect of frozen live food (Daphnia magna) and artificial diets on growth performance, feed conversion ratio and survival of Cyprinus carpio fry reared in 25-liter glass aquaria. Duplicate groups of fry were fed o
n the tested diets three times a day to satiation for 21 days.
The results revealed that the growth rates (weight gain, % weight gain) were significantly (P<0.05) affected by the used diets. Fry fed on the frozen live food showed the worst growth rates, even their feed conversion ratio expressed the lowest value compared with the results obtained from fry fed on the artificial diets, although survival was not significantly (P>0.05) affected with the different diets. No significant differences (P>0.05) were noticed in the results obtained from fry fed on the different artificial diets.
This research aimed to study the effect of adding different rates of lysine on the weight and
growth of common carp fingerlings. The experiment was carried out in the laboratory for 4
months using eight glass containers (40 liters each) with four t
reatments (L0 no Lysine
addition, L1 (2%), L2 (3%), L3(4%) of the total weight of diet. Eight common carp
fingerlings (average of tall 7.5cm ± 0.05 and average of weight 12.25g ± 0.57) were
cultured in each container with Oxygen pumps and filters.
Results showed by growth rate, absolute growth rate, specific growth rate and food
conversion ratio (FCR) that the treatment L1 (2% lysine) was significantly the best
comparing to the other treatments, where FCR was (2.2) and the specific growth ratio was
(0.28 %)
The aim of this research is to study the most important physical, chemical and
microbial changes in several kinds of infant milk available in local markets. The milk
samples were studied in conditions similar to those used by mothers when they prep
are
infant milk bottles at their houses. The results showed that moisture content increased in all
samples from approximately 1% to 3.2-4.4% after storage for 9 days. Acidity increased
considerably from 0.14% to 0.2%.
The results showed that peroxide value passed the allowable limits (0.25) and
reached about (0.47) in samples stored for 9 days at room temperature. However, the value
for samples stored in the refrigerator ranged between (0.25-0.29). The free acidity number
of fat for all samples specially the refrigerated ones was within the natural limits (<0.5).
Chromatographic analyses showed apparent differences in fatty acid percentages between
the kinds of milk. The rate of lenoleic acid (C 18-2 ) decreased during storage in all samples
and in all conditions.
Soluble nitrogen increased in all samples at the end of storage and the highest value
was 0.49% in Nido milk samples. The solubility of milk samples was checked during
storage and was found to decrease very little ( 1%).
The total count of aerobic bacteria showed that all samples conform to the Syrian
standards (No. 197, 1996) during the first six days of storage, but they passed the upper
limits at the end of storage. However, all samples were free of pathogenic microbes .
The main purpose of this research was to identify the impact of customers' perception of corporate social responsibility on behavioral intentions, and evaluate these intentions by measuring corporate image and consumer satisfaction. This includes ide
ntifying the impact of customers' perception of economic, social and environmental dimension of this responsibility on the satisfaction and corporate image, and then study their impact on behavioral intentions .
