هدفت هذه الدراسة للمقارنة بين طريقتين لتوقيت الشبق في النعاج (الإسفنجات المهبلية المشبعة بميدروكسي بروجستيرون أسيتات (MAP) والحقن العضلي لهرمون البروستاغالندين) داخل الموسم التناسلي، وتأثيرهما على بعض المؤشرات التناسلية لدى النعاج العواس. استخدمت في هذه الدراسة 30 نعجة تم تقسيمها إلى مجموعتين متساويتين(G1 وG2) . وضعت الإسفنجات المهبلية المشبعة بـ 30 ملغ من ميدروكسي بروجستيرون أسيتات (MAP) لمدة 14 يوما وحقنت في وقت سحب الإسفنجات بـ 500 وحدة دولية من الهرمون المشيمائي الخيلي (eCG) لدى نعاج المجموعة الأولى (G1) ، في الوقت الذي حقنت فيه نعاج المجموعة الثانية (G2) بـ 125 ميكروغرام من هرمون البروستاغالندين (PGF2α) بالعضل بجرعتين بفاصل 9 أيام، لقحت النعاج بكباش ذات خصوبة عالية بمعدل (كبش/5نعاج). أظهرت النتائج عدم وجود فروق معنوية بين المجموعتين (G1 وG2) في نسبة ظهور الشبق فقد بلغت 100%و86.67%على التوالي، في حين ظهرت فروق معنوية في متوسط طول الفترة بين انتهاء المعالجة وظهور الشبق (4.45±38.8 ساعة و4.13±53.07 ساعة على التوالي للمجموعتين) و في متوسط طول فترة الشبق(3.09±33.20 ساعة و 3.59±28.61 ساعة على التوالي)، كما تفوقت نعاج المجموعة(G1) وبفروق معنوية واضحة (0.05>P) في نسبة الحمل مقارنة بالمجموعة (G2) (93.33%مقابل 73.33%)نستنتج من الدراسة أن توقيت الشبق باستخدام الإسفنجات المهبلية تعتبر طريقة فعالة لتحقيق أداء تناسلي جيد للنعاج والحصول على نسبة ظهور للشبق ونسبة حمل مرتفعتين مقارنة بحقن هرمون البروستاغلاندين لدى النعاج العواس ضمن الظروف المحلية السورية
The objective of this study was to compare between two methods of estrus synchronization (progesterone-impregnated intravaginal sponges and intramuscular (IM) injection of prostaglandin hormone) within the reproductive season and their effect on some reproductive parameters in Awassi ewes. Thirty ewes were equally divided into two groups (G1 and G2). Intravaginal sponges impregnated with 60 mg of Medroxy Acetate Progesterone (MAP) were inserted into the ewes of the first group for 14 d, and were injected at the time of the withdrawal of sponges with 500 IU of equine Chorionic Gonadotrophin (eCG) at the first group ewes (G1). The animals in second group (G2) were injected with double dose of 125μg of prostaglandin (PGF2α) intramuscularly (IM) at 9 days apart. The ewes were naturally mated with fertile rams (ram / 5 ewes). The results showed that there were no significant differences between groups (G1 and G2) in the estrus response (100% and 86.67%, respectively), while there were significant differences in the average time to onset of estrus (38.8 ± 4.45 h and 53.07 ± 4.13 h) and the average duration of estrus (33.20 ± 3.09 h and 28.61 ± 3.59 h, respectively). Also, the pregnancy rate was significant difference (P<0.05) in group G1 compared to group G2 (93.33% vs. 73.33%). we conclude from the study that the estrus synchronization using intravaginal sponges is an effective method to achieve good reproductive performance ewes and get a high estrus rate and high pregnancy rate, compared to the injection of the hormone prostaglandin in Awassi ewes, within the local Syrian conditions.

The objective of this study was to compare the effect of using intravaginal sponges with intramuscular (IM) injection of prostaglandin hormone within the reproductive season and their effect on Lambing rate and birth rate in Awassi ewes. Thirty ewes
were equally divided into two groups (G1 and G2). Intravaginal sponges impregnated with 60 mg of Medroxy
Progesterone Acetate (MAP) were inserted into the ewes of the first group for 14 days, and were injected at the time of the withdrawal of sponges with 500 IU of equine Chorionic Gonadotrophin (eCG) at the first group ewes (G1). The ewes in second group (G2) were
injected with double dose of 125 μg of prostaglandin (PGF2α) intramuscularly (IM) at 9 days apart. The ewes were naturally mated with fertile rams (ram / 5 ewes). The results showed that there were significant differences between groups (G1 and G2) in the Lambing rate (93.33% vs. 73.33%). The ewes of group (G1) outperformed the ewes of group (G2) in the
percentage of twin births (42.86% vs. 18.18%), and the birth rate (1.43 vs. 1.18) with significant differences (P<0.05). We conclude from the study that treating ewes by using intravaginal sponges with eCG injection was better than the method of prostaglandin
injection in raising the Lambing rate and birth rate in Syrian Awassi ewes, within the local Syrian conditions
١٢٠ -Awassi ewes, ٣٦ ± ٢,٠ mos. old, ٤٢,٥ ± ٢,٥ kg. weight were used to
know the efficiency of artificial insemination (AI) in reproductive performance
of hormonal treated Awassi ewes in breeding season.
Data on ١٦٠١ records over five years were used to study the reproductive
and productive performance of Awassi ewes kept at the animal husbandry
station (Darnajookh) in Iraq.
The overall means were ٨٠,٦٩±١,١٪, ١,٠٧٧±٠,٠٠٨, ٩٢,٨٢±٠,٨٣٪,
٠,٨٠٥±٠,٠١٤
, ١٨,٩٨±٠,٣٥ kg, ٥٣,٣٨±٠,٣٢ kg and ٢٢,٥١±٠,١٨ kg for
fertility, litter size, pre-weaning survival rate, number of lambs weaned per
ewe exposed to the rams, ewe productivity ( total weight of lambs weaned
per ewe exposed to the rams), body weight of ewe at breeding and weaning
weight of lambs, respectively.
This study aimed to provide an assessment of some anatomical
characteristics of the formal comparison to the kidneys of dogs
and sheep by studying of macroscopic anatomical differences and
morphometric measurement between the studied kidneys . (20
)
Kidneys were taken randomly during the slaughter of ten heads of
sheep in the local slaughterhouses, regardless of gender and age ,
Animals were clinically free of diseases and (20) kidneys were
taken from ten local stray dogs and regardless of gender and age ,
Animals were clinically free of diseases . the study showed the
presence of Morvomitrih differences in kidney (length – width -
thickness - weight) and some anatomical variations (renal pelvis -
renal Columns )between the kidneys of sheep and dogs. The study
pointed out there are many similarities between the kidneys of
sheep and dogs whereas revealed the length of the dogs kidneys.
This study aims to shorten the orthodontic treatment period
into,at least, half the length of time. It takes in order to reduce the
complaints of patients of the length of orthodontic treatment through
the induction of the secretion of prostagland
in E2 topically by
raising the inflammatory process via injection of vitally accepted
materials which are used routinely in daily dental practice,
Lidocaine 2% which leads to the increase of proportion of
osteoclasts and the occurrence of bone absorption in the injected
area ( the area of the tooth to be moved) .
