A study was conducted to determine the effect of three native plants from El-Jabal al ELAkhdar, (Libya) on hematological profile, cholesterol and immune response to ND vaccine in broiler chickens. A total of 1260 one-day-old male Cobb chickens were used in the experiment. Chickens were assigned to 7 treatment groups (6 replicates per treatment). The dietary treatments included basal diet with no additives (control), and 6 other dietary treatments (Arbutus pavarii, Salvia officinalis and Zizyphus Vulgaris) each of which was added at the rate of 0.5g and 1g/kg of basal diet. Results explicitly revealed that no significant change in TLC between the treated and control groups has been recorded. A significant heteropenia was recorded at the third week of treatment with 1% A. Pavarii 0.5 S. Officinalis and 0.5 Z. Vulgaris when compared to control group. However, the lymphocytic count show a significant increase (P≤0.05) in all treated groups compared to the control groups. Immunologically, an enhanced humeral immune response was very obvious based upon the significant elevation of antibody titer at the third week of treatment for all groups received 1 % of the three types of plants. Interestingly , cholesterol levels were significantly elevated at the six week of treatment with 0.5 % Z. Vulgaris while highest decline in cholesterol levels were recorded in group that have received 0.5 S. Officinalis.

The deleterious effects of the residues of antibacterial drugs have been considered as one of the most serious problems in the world on the basis of their importance in both veterinary and human fields. Therefore, the present study was planned out to evaluate the residual levels of oxytetracycline in camel tissues in Tripoli area in Libya. Forty samples of slaughtered camel's tissues (10 of muscle, 10 of liver, 10 of kidney, and 10 of fat) were collected from different carcasses at different slaughter houses in Tripoli districts. The samples were homogenized, extracted and residual concentrations of oxytetracycline have been measured using liquid chromatography-Mass spectroscopy (LC-MS) technique and oxytetracycline standard. Oxytetracycline residues have been detected in 60% in muscle, 80% in liver, 90% in kidney and 70% in fat samples. The samples, although positive, yet decided acceptable as the detected levels were less than that were regulated by Codex Alimentarius Commission (CAC) for oxytetracycline maximal residual levels (100, 300, 600 and 100 μg/Kg muscle, liver, kidney or fat, respectively). The authors recommended avoiding irrational use of oxytetracycline in veterinary practice and camel in particular; and sticking to the withdrawal time regulated and labelled for drugs used in therapy among veterinary personnel, organizations, and governmental agencies in Libya.

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
