Relationships between carpal morphology and carpal pathology might assist in identifying horses at risk of carpal pathology. This study was aimed to investigate the hypothesis that carpal morphology is related to the incidence of carpal pathology in racing Thoroughbreds. Ten carpal parameters were used to measure carpal morphology on dorsopalmar (DP) carpal radiographs. Radiographs were collected from 19 experienced Thoroughbred race horses with no evidence of carpal damage(normal)and 72 horses with carpal damage (clinical). All radiographs were at a defined position called zero degrees (ZDP) or within an acceptable rotational range. Based on a P-value of < 0.05 and using the false discovery rate method to control Type I error, two parameters showed significant differences between normal and clinical horses. The angulation of the radial metaphysis and distal radius in relation to the angulation of the radial facet of the third carpal bone (C3) was significantly related to the occurrence of pathology in the bones of the middle carpal joint in Thoroughbred race horses. This study presented important features on DP radiographs that allowed identification of a carpal conformation associated with carpal damage in Thoroughbred race horses. Using such a highly specific, cost-effective and safe technique as a routine for examining yearling Thoroughbreds would assist in identifying horses with carpal conformation unsuited to racing.

Background: Orthopedic diseases involving the forelimb fetlock joint of horses other than those used in professional racing have not been widely reported in the literature. One of these problems is the exostosis on the proximal forelimb phalanx (P1), which has not been reported previously in Western Libya. Aim: The study aimed to investigate the prevalence of P1 exostosis in traditional equestrian horses (known locally as Sarj horses) of different breeds in Libya that participated in a special social event and described its clinical findings radiographic appearance. Methods: The current study involved 60 horses admitted to private veterinary clinics with varied fetlock orthopedic problems. The studied horses were aged between 6 and 11 years old and galloped on hard grounds. Clinical and radiographic examinations were carried out on all horses. Lateromedial radiographs for one or both forelimb fetlock joints were acquired for each horse. Results: Clinical examination revealed that 21 horses (35%) had hard non-painful swelling on the dorsal aspect of fetlock with joint stiffness during flexion. In 19 of them, the swelling was bilateral. No forelimb lameness was noticed. Radiographically, hard swelling was diagnosed as bone exostosis, with various sizes, on the proximo-dorsal aspect of P1. There was also a new bone formation on the disto-dorsal part of third metacarpal bone in two cases. Conclusion: This study has documented the first report on bone exostosis on the proximo-dorsal aspect of the forelimb proximal phalanx as a common problem in Sarj horses that galloped on hard grounds in Western Libya. Although this bone lesion did not cause lameness in all reported cases, further investigations are warranted to identify its histopathological nature, potential etiology, and proper treatment.

تم إجراء هذه الدراسة بمنطقة الزاوية و التي تبعد 60 كم غرب مدينة طرابلس في مزارع خاصة للأغنام. أجريت الدراسة في الفترة الزمنية من شهر ناصر(يونيو) 2008 إلي شهر هانيبال (أغسطس) 2009. لقد كانت أهداف هذه الدراسة, البحث و التقصي عن موسمية التناسل و تقييم فعالية عدد من المعالجات الهرمونية في إحداث الشبق و توحيده لتحسين الأداء التناسلي للنعاج البربري الليبية. ولتحقيق هذه الأهداف, تم تنفيذ أربع تجارب مستخدمين فيها 475 نعجة بربري ليبية سليمة و خصبة إضافة إلي عشر كباش سليمة وخصبة من نفس السلالة. التجربة الأولى: تم استخدام 300 نعجة لدراسة عن الموسمية التناسلية لهذه النعاج باستخدام البروستاجلاندين α2F (PGF2α ). قسمت الحيوانات إلي أربع مجاميع و حسب فصول السنة (100, 55, 100و 45 نعجة) للصيف, الخريف, الشتاء و الربيع على التوالي, تم تقسيم كل مجموعة من هذه المجاميع إلي مجموعتين (مجموعة المعالجة و مجموعة المراقبة), تم حقن مجموعة المعالجة بجرعتين (125ميكروجرام( من PGF2α بالعضل بفاصل 11 يوما بين الجرعة الأولى و الثانية. بينما تم حقن مجموعة المراقبة 1 مليلتر بالعضل من المحلول الفسيولوجي (NaCl 0.9) بجرعتين بفاصل 11 يوما بينهما. عند الانتهاء من حقن الجرعة الثانية في كلتا المجموعتين, تم إدخال الكباش للتلقيح الطبيعي لمدة ستة أيام. كانت الفترة الزمنية لظهور علامات الشبق بعد الانتهاء من المعالجة (الجرعة الثانية) مختلفة معنويا جدا (P
