o investigate the effect of thyroid hormones Thyroxine (T4) and Triiodothronine (T3) on bodyweight performance in broiler hens. Methodology: The hens were kept in a controlled environment of 50-60% humidity at 31oC in first two weeks than temperature been decreased to 24oC with 24 hr light cycle per day, and were treated gently. Water and feed were provided ad libitum for the all hens. The body weight of the birds detected at the day 2nd, 4th, 6th and 8th week of the experimental period and blood sample detected at the day 14th,28th,42th and 56th day of the experimental period. The data were analyzed by the analysis of variance technique in completely randomized design, while the differences between means were tested by Duncan New Multiple Range Test as per SAS. Results: It was noted that there is a highly significant effect of age, at the level (P ≤ 0.01) on the characteristics of each of the concentration of the hormone T3 and T4 hormone levels and body weight. This study showed that there is a difference in the average concentration of "T4 & T3" for meat birds of different ages. The correlation coefficient manner, "Pearson" between the different qualities of the birds of the meat where it was noted there is a strong inverse relationship between "T4 & T3". arabic 11 English 77

بكتيريا الفيبريو وهي مجموعة من البكتيريا سالبة الجرام التي تصيب في الأساس أسماك المياه المالحة والشروب. بكتيريا الفيبريو توجد بصورة كثيفة في مياه البحر الملوثة و خصوصا تلك الملوثة بمياه الصرف الصحي. في الدراسة الحالية تم عزل وتصنيف عدد أربعة عترات من ميكروب الفيبريو من أسماك المرجان العادي التي تم تجميعها من المنطقة الساحلية لطرابلس خلال موسم 2014 حتي موسم الربيع 2015 . تم تحديد هوية العترات المعزولة والتأكيد علي انها ميكروب V. Parahaemolyticus, Vibrio vulnificus, Vibrio fluvialis, Vibrio alginolyticus وباستخدام بعض التقنيات البيوكيميائية التقليدية و تقنية API20E. وأكدت الاختبارات اتفاق الخصائص البيوكيميائية مع الخصائص لقياسية لذلك الميكروب و المسجلة في كتاب بيرجز المرجعي لتصنيف البكتيريا (Bergey’s Manual Bactriology) بالبحث تبين أن ميكروب V. fluvialis سجل أعلى نسبة عزل خلال موسم صيف 2014 (33.33%) وربيع 2015 (27.77%) بينما مثل ميكروب V. ulnificus اقل نسبة عزل في موسم صيف 2014 بنسبة (4.44%) وربيع 2015 (5.55%). في موسم شتاء 014 مثلت V. Parahaemolyticus أعلى نسبة إصابة (20%) بينما مثل ميكروب V. alginolyticus أقل نسبة إصابة (2.22%). بالنسبة لاختبار الحساسية وجد أن معظم ميكروب V. alginolyticus و V. Parahaemolyticus هي حساسة لكل من الدوكسيسيكلين و البوليميكسين و مقاومة لكل من الاوكسيتيتر اسكين و الفلورفينيكول و الا مبيسيلين. و على الرغم من ذلك فإن ميكروب V. fluvialis أثبت حساسية كل المضادات الحيوية المستخدمة باستثناء الأمبيسيلين بينما أثبتت الاختبارات حساسية ميكروب Vibrio vulnificus لكل من الدوكسيسيكلين و البوليميكسينو الاوكسيتيتر اسكلين و مقاومة للفلورفينيكول و السلفاميثاكسازول- تراميثوبريم و الأمبيسلين و الذي يظهر اختلافا ملحوظا عن باقي العزلات البكتيرية. و في المجمل فإن النتائج تعطى مؤشر عن ازدياد مستمر للتلوث بمياه الصرف الصحي في معظم أماكن تجميع العينات في المنطقة الممتدة من تاجوراء حتى جنزور على الشاطئ الغربي لمدينة طرابلس ليبيا. Abstract: Vibrios are a group of Gram negative septicemic bacteria that mainly affect marine and estuarine fishes. Vibrios are ubiquitous in environmentally polluted seawater with especial reference to municipal sewage. In the current study, four main species of Vibrios have been frequently isolated / identified from the Common Pandora fish (Pagellus erythrinus) collected through summer 2014 to spring 2015. The identities of the retrieved isolates were confirmed as Vibrio vulnificus (V.vulnificus), Vibrio Parahaemolyticus (V. Parahaemolyticus), Vibrio fluvialis (V.fluvialis) and Vibrio alginolyticus (V. alginolyticus) depending on their morphochemical results obtained from the adopted conventional and semi-automated biochemical tests (API20E). All isolates were consistent with the standard criteria of the aforementioned Vibrio species stated by the Bergey's Manual of Systemic Bacteriology. The research has revealed that V. fluvialis was the highest isolated species (33.33%) in Summer 2014 and Spring 2015(27.77%), while V. vulnificus was the lowest isolated through summer 2014 (4.44%) and spring 2015(5.55%) . In winter season 2014, V. Parahaemolyticus presented the highest percentage of infection (20%), while V. alginolyticus was associated with the lowest percentage of infection (2.22%). Antibiogram has revealed that most of the retrieved V. alginolyticus and V.Parahaemolyticus were sensitive to Doxycyclin and Polymyxin and resistant to Oxytetracyclin, Florfenicol and Ampicillin. However V. fluvialis isolate were sensitive to all tested antibiotics with the exception of Ampicillin. Interestingly V.vulnificus were sensitive to Doxycyclin, Polymyxin, Oxytetracyclin, while resistant to Florfenicol, Sulfamethoxzole -trimethoprim and Ampicillin, which is remarkably different from the antibiogram recorded for other retrieved Vibrio species. Conclusively, the achieved results throughout the current study is indicative of a consistently growing municipal sewage pollution across the sampling sites extending from Tajoura to Janzour at the western coast of Tripoli, Libya.

Poor performance in athletic horses due to musculoskeletal affections is very common in Libya. Two mature thoroughbred horses suffering from poor performance and history of moderate degree forelimb lameness were admitted to the Aswany Private Equine clinic in Tripoli, Libya. The study is aiming for presenting a simple, time effective, cost effective surgical procedure to treat distal simple splint bone fracture in thoroughbred horses. Horses were examined thoroughly for the common muscle, hoof, and tendons affections. A progressed unilateral left forelimb swelling involving the lateral distal part of the fourth metacarpal bones was noticed. Three radiographs were taken to each horse including latero- medial, dorsolateral-palmaromedial, and palmarolateral-dorsomedial views to assess both splint bones. The radiographs showed that there is a complete fracture involving the distal extremity (button) of the fourth metacarpal bones. Surgical excisions of the fractured part of the splint bones have been decided to treat these horses. To precisely locate the site of the bone fragments, 1.5 mm stainless steel wires were placed over the distal part of splint prior to taking the radiographs. The surgical sites were aseptically prepared, and the horses were then sedated via intravenous injection of xylazine at a dose rate of 1 mg/kg body weight. The site of surgical incision was infiltrated with 2% lidocaine. The bone fragments were then removed after performing the surgical incision. The sharp end at the distal end of the proximal part of the splint bone was then smoothening with a scissor. The surgical incisions were then routinely closed and the post-operative care and radiographs were taken. The surgical incision made complete healing within two weeks. Both horses were followed up for up to three years post-operation, and they did well compared to what has been done in other studies. We concluded that the surgical technique used to treat the two horses with splint bone fracture enrolled in the current study is a simple and effective procedure. arabic 19 English 106
