وزعت 252 صوصاً من الفري الياباني وهي بعمر يوم واحد عشوائيا إلى مجموعتين، حيث عرضت صيصان المجموعة الأولى في مرحلة الحضانة إلى درجات الحرارة المثلى بما يتماشى مع عمر الطيـر، في حين عرضت المجموعة الثانية إلى درجة حرارة مرتفعة 42°س خلال سـاعات النهـار (الـساعة 8 صباحاً حتى الساعة 5 مساء)، و عرضت خلال ساعات الليل لدرجات الحرارة المثالية، وزعت صيصان كل مجموعة إلى ثـلاث تحـت مجموعـات غـذيت علـى ثـلاث مـستويات مـن فيتـامين C) 0 ،و 10 ، و 20 غ /ل)، ضمت تحت المجموعة الواحدة ثلاثة مكررات. أخذت عينات الدم من ثمانيـة عـشر طيـراً اختيرت عشوائياً و هي بعمر 30 يوما لتحديد مدى تأثير الإجهاد الحـراري و مـستوى فيتـامين C فـي مؤشرات الدم في طيور الفري.
This study was conducted at Gharabo farm, Fac. Agric. Damascus Universityin order to determine the effect of heat sress and level of vit. C on the blood indicators of of Japanese quailc A total of 252 females Chicks were distributed randomly into two groups (G and G2) at one day of age, The chicks in G1were subjected to an ideal temperature required according to their age up to 30 days old, while the chicks in G2 were subjected to heat stress at 42 °C during the daytime from 8 am to 5 pm and to ideal temperature from 5pm to 8am for the same period of rearing. Chicks of each group were distributed into three subgroups given three levels of vitamin C: 0, 10 and20 g/l, with three replicates for each sub-group during the rearing period. Blood samples were collected from eighteen birds selected randomly from each group. Results indicated that there was a significant increase in both red blood cells and hemoglobin in the stressed group.

This experiment was conducted at Kharabo farm, Faculty of Agriculture,
University of Damascus. A total of 252 chicks of Japanese quail breeder females
were distributed on the first day of life into two groups, Gicks in G1 were
reared from 1-28 day
s of age under ideal required temperature according to
their age, while chicks in G2, were subjected to heat stress from 8 am to 5 pm at
42 °C from the first day of hatching until 28 day of age and to the ideal
required temperature from 5 pm until 8 am. Chicks of each group were
distributed into three subgroups, with three replicates per subgroup.
In research we studied the effect of vitamin C on the level of total
cholesterol ،triglycerides ، (HDL) and (LDL) in the stressful
rabbits blood by hydrogen peroxide (H2O2) . We used 30 rabbits
were divided into three groups:First groupnot stresse
d (control
group) ، Second group (Group stressed by H2O2) left without
treatment until the end of the experimental period ، third group
(Group stressful by hydrogen peroxide) was given orally vitamin C
solution at a rate of 100 mg / kg of body weight per a day for five
weeks.
In this research, the quantity of vitamin C which extracted from fresh fruits and
vegetables was evaluate by using titration method with 6-2 Dichloro phenol andovinol, and
studying the effect of conservation and different temperatures (30, 60, 90)
°C which used
in cooking on content of vitamin C for some samples. Also this search included studying of
the effect of iron ions on content tomato, orange and lemon of vitamin C.
The results showed that the concentration of vitamin c in studied samples: parsley,
red pepper, green pepper, lemon, orange and tomato was (8, 22, 36, 144, 175, 133)
mg/100g respectively. Losing of the vitamin was (66%, 65%) when we save the leaves and
stalk of parsley for 24 hours respectively, when exposure the parsley leaves to the
temperatures (30, 60, 90) c° the losing percentage was (24 %, 41%, 62 %), While the
losing was (79%, 65%, 39%) when injected each of tomatoes, oranges, lemons with
dissoluble of iron.
This study was carried out in Hama Scientific Research Center from
04/22/2010 until 01/08/2010. Twenty eight Awassi aged 160-180 daysold,
and weighed 30 kg in average were assigned into four groups, and
continued the experiment for two (101 days)
them (11 days) introductory
period to accustom the sheep on the bush studied in order to study the
effect of olive pomace on some blood chemical components levels in
Awassi sheep the one hand, and the impact of the using olive pomace on
their live weight on the other hand.
This study was carried out at the poultry experimental station, Technical
Institute of Agriculture, Damascus University, Kharbo. 270 of Japanese Quail
birds, one day of age were divided equally into 3 similar groups (90each). Every
group comprised
of 3 replicates of 30 each, each replicates contained 10 cages.
Birds were housed and managed under similar conditions throughout the
experimental period which lasted from the 8 to 22 weeks of age. The birds were
fed on rations recommended by NRC and contained 1, 0.65 or 2 of DLmethionine
g/kg of ration in the first (the control), second and third groups
respectively. Results showed that using ration contained 2g DL-methionine/
1kg of ration gave a significant increase in egg weight, production and
economical efficiency value as compared to the other used rations.
