نُفّذَ البحث على 270 فرخة (إناث فقط) من الفري الياباني في مدجنـة المعهـد التقـاني الزراعـي بدمشق–جامعة دمشق -خرابو، وزعت الطيور منذ بداية التجربةإلى ثلاث مجموعات بمعدل 90 طيراً في كل مجموعة، ضمت كل مجموعة ثلاثة مكررات بمعدل 30 طيراً في المكرر الواحـد، و أُجريـت رعايـة الطيور للمجموعات جميعها في أقفاص تحت ظروف إيواء خلال مدة الإنتاج التي استمرت مـن عمـر 8 أسابيع إلى عمر 22 أسبوعاً، أما تغذية طيور المجموعات المختلفة فقد كانت مختلفة و على النحو الآتي: غذيت طيور المجموعة الأولى (الشاهد) على خلطات الموصى بها (NRC1994) و احتوت خلطاتها على 1غ DL- مثيونين إلى كل كيلو غرام خلطة علفية (1.0%من الخلطة العلفية). و غذيت طيور المجموعـة الثانية على خلطات الموصى بها (NRC1994) مع إضافة 65.0 غ DL - مثيونين لكل كيلوغرام خلطـة علفية (065.0%من الخلطة العلفية) ، و غذيت طيور المجموعة الثالثـة علـى خلطـات الموصـى بهـا (NRC1994) مع إضافة 2غ DL - مثيونين إلى كلّ كيلوغرام خلطة علفية (2.0% من الخلطة العلفية).
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.

The study was carried out at the experimental station, Faculty of
Agriculture. Damascus University. 1464 of the hybrid Lohman broiler chicks,
one day old, were divided randomly and equally into 8 groups (182 chicks/ G)
with 3 replicates of 61 chic
ks each. Chicks in each replicate were reared
separately on deep litter in an independent room of open housing till the age of
42 days. All housing and management procedures were similar for all chicks
while the feeding was different throughout the fattening period in terms of the
amounts of lysine and methionine added to the mix feed. Chicks of G1, G2, G3
and G4 were fed on plants mixtures supplemented with 1, 1.5, 2 and 2.5 kg/ ton
of methionine, respectively. Chicks in G5, G6, G7 and G8 were fed on the same
mixtures of the previous groups but supplemented additionally with 1kg/ton of
lysine. Result showed that adding lysine 1kg/ton and methionine 2kg/ton to
plant mixtures of feeds of broiler helped in improving significantly most of the
indicators of productivity and this in turn led to a reduction of the cost of
feeding and to produce 1 kg live weight, thereby raising the index profit from
the process of fattening and increasing the gain from fattening process.
The study was taken place at the experimental station (kharabo), Faculty of
Agriculture, Damascus University, 1464 - one day old chicks of the hybrid
Lohmann were used to determine the effect of adding different levels of
methionine without or wit
h lysine on some of carcass traits. Chicks were
divided randomly and equally into 8 groups (183 each) at the first day with 3
replicates for every group (61 each).
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.
The research was carried out on (960) broiler chicks of the hybrid Hibrd in
the Poultry Unite of Kharabo–Agriculture Faculty–Damascus University,
during 27/10/2003 and 23/12/2003.
The chicks were distributed randomly since the first day of age int
o four
experimental groups, every group contained 240 chicks distributed as four
replicates, every replication contained 60 chicks, the area of the replication was
5.5m2 and the density was 11 chicks/m2. Every replication is an independent
sector from byre is open type on deep litter, all conditions of keeping and
caring were the same for all birds of replications.
The purpose of research was to study of effect of using different levels of the
energy and raw protein into mixtures of (pre-starter) since the first day until
sixth day of age on absorption of yolk sac, growth of digestive system ,and some
productive parameters of broiler. 48 chicks were dissected, the chicks were
distributed as 16 chicks in the first day and 16 chicks in the fourth day and 16
chicks in the sixth day of age, from every group 4chicks were evaluated.
The trial was carried out during the season 2014, on grapevines
of Al-Baladi. Al Baladi, 20 years old, grafted onto rootstock, and trained in the trellis way, to study the influence of different levels of 4 times/season soil applied seaweed extract , on some qualitative and quantitative characteristics of Al-Baladi grapes.
