ُنفذت الدراسة في كلية الزراعة بجامعة دمشق، في الفترة الواقعة بين بداية آذار و بداية تموز من عام 2001 م على 37 أنثى من الأرانب المحلية السورية في عمر البلوغ، مرباة بشكل إفرادي في أقفاص معدنية بطابق واحد ذات قياس 60×50×40 سم معزولة عن بعضها بحواجز معدنية. زودت الأقفاص ببيوت للولادة و بمعالف نصف آلية (تعبأ يدويًا) و بحلمات أوتوماتيكية لتأمين مياه الشرب. قسمت هذه الحيوانات حسب اللون إلى 5 مجموعات هي الأبيض، الأسود، الأبيض و الأسود، الأحمر، الرمادي بمعدل 6 إناث في كل مجموعة بالإضافة إلى مجموعة سادسة للون البني تضم 7 إناث. وضع ذكران مع كل مجموعة. علفت الحيوانات بعليقة متوازنة. ُلقحت إناث المجموعات طبيعيًا بوقتٍ واحدٍ تقريبًا. سجلت بعض المؤشرات الإنتاجية الخاصة بالإناث كنسبة الإخصاب، مدة الحمل و متوسط عدد المواليد في البطن الواحد عند عمر يوم واحد و 7 أيام و 28 يومًا (الفطام) و 56 يومًا و 84 يومًا.
This study was conducted in the Agricultural college, Damascus university during the period from March 1ST until the beginning of July 2001 to determine some productive parameters in local Syrian female rabbits. Seventy six adult females and twelve bucks from the local rabbits were used in the present study. These animals were divided according to their color into five groups (6 females each). The colors were white, black, white and black , red, gray and one group (7 female) of brown color. The animals were housed individually in cages. The females of each group were randomly bred with tow bucks. The parameters studied were: conception rate, gestation period and litter size at birth, 7 days, weaning (28 days), 56 days and at the Age of 84 days.

This study was conducted at the Faculty of Agriculture, Damascus
University, during the period from the beginning of January and the beginning
of April, during the year 2002, on 107 local rabbit offsprings at one day age,
were divided according to
the color into five groups: 27 white, 22 black, 25
brown, 14 red, and 19 gray, then given numbers at the birth on her abdomens
and were weighted weekly, after that they were weaned at age 28 days.
For studying the effect of cadmium sulphate on some physiological components
of blood in male white rabbits. we used (12) animals divided in to two groups (6 animals
per group).the experimental one became aqueous cadmium sulphate (5 mg/kg) orally,
while the control became water for 28 days (4 weeks).
We reported significant decrease (p<0.01) in the count of red blood cells ,
Hematocrit values and Hemoglobin concentration.
The current investigation was conducted to study some
productive properties( body weight, body weight gain, feed intake,
feed conversion ratio, carcass composition, and carcass cuts ) on
some broiler strains in Syria ( Ross, Hubbard, and Shefer ).
The aim of this experiment to study some of the blood parameters
associated with hepatic coccidiosis induced by Eimeria stiedae in
rabbits, and compare it with the blood changes when infected
rabbits treating with the toltrazuril compound.
21 rab
bit-old (4-8 weeks) were Used for this experiment of both
sexes and were divided into three groups (seven rabbits in each
group): Group of natural witness, and a Group of patient witness,
where the infection caused by challenge dose of about forty
thousand mature oocyst for each rabbit by mouth, and a treatment
group that has been given the same previous challenge dose.
This study was conducted at the farm of the Faculty of Agriculture
(Damascus Univ.), using twenty local rabbits.
These rabbits were housed, managed and fed under the same conditions.
They were identified and distributed into two groups according to the weaning
times (٢٨ vs ٤٢ days).
It was concluded that weaning time has no significant effect on meat
proportion in local rabbits.
