Tab titleThis study was conducted to find out the effect of using different percentages of wild thyme, Thymus serpyllum in the diets of Awassi lambs, and its effect on growth, carcass characteristics, blood traits and some properties of rumen fluid. This experiment was conducted in field of the Department of Animal Production of College of Agriculture and Forestry at University of Mosul. In this experiment, 24 twenty four male Awassi lambs were used, their ages ranged between 5-6 months, lambs were randomly distributed to 4 four treatments and each treatment included 6 six replicates of lambs. The lambs were raised and fed for a period of 90 days From date of (11/11/2020) the beginning of the experiment to date of slaughtering animals for sampling for research purposes on (9/2/2021). And lambs of first treatment (control) were fed on a standard diet only. Free from any additives consisting of barley, wheat bran, wheat straw, soybean meal, limestone and salt, a second treatment was added wild thyme 10 gm/kg feed/head daily, third treatment was 20 gm/kg feed/head daily and fourth treatment was 30 g/kg of feed/head per day. The results of experiment did not show significant differences in daily and total weight gain and carcass characteristics. The results of pH of rumen fluid before feeding or after feeding two hours, nor concentration of rumen liquid ammonia two hours after feeding did not show significant differences between the four treatments. As for the ammonia concentration of the rumen fluid before feeding, it indicated a significant superiority (P≤ 0.05) in treatment. Fourth compared to other transactions. Also, no significant differences were observed in blood characteristics. Keywords: wild thyme – Awassi lambs – growth – characteristics of the carcass – nutrition.

أُجريت هذه الدراسة لمعرفة تأثير استخدام نسب مختلفة من الزعتر البريThymus serpyllum في علائق الحملان العواسية وأثرهُ في النمو وصفات الذبيحة وصفات الدم وبعض خواص سائل الكرش، إذ أُجريت هذه التجربة في حقل قسم الإنتاج الحيواني التابع لكلية الزراعة والغابات في جامعة الموصل. استخدم في هذه التجربة 24 أربع وعشرون حملاً ذكراً عواسياً تراوحت أعمارهم ما بين 5- 6 أشهر، وزعت الحملان بشكل عشوائي على 4 أربع معاملات وكل معاملة تضمنت 6 ست مكررات (حملان)، تم تربية وتغذية الحملان لمدة 90 يوماً من تاريخ (11/11/2020) بداية التجربة إلى موعد ذبح الحيوانات لأخذ العينات لأغراض البحث في تاريخ (9/2/2021). وغذيت حملان المعاملة الأولى (السيطرة) على عليقة قياسية فقط خالية من أي أضافات تكونت من الشعير، نخالة الحنطة، تبن الحنطة، كسبة فول الصويا، حجر الكلس وملح، المعاملة الثانية تم إضافة زعتر بري 10 غم/ كغم علف/ رأس يومياً، المعاملة الثالثة 20 غم/ كغم علف/ رأس يومياً والمعاملة الرابعة 30 غم/ كغم علف/ رأس يومياً. لم تظهر نتائج التجربة وجود فروق معنوية في الزيادة اليومية والكلية بالوزن وصفات الذبيحة. ولم تظهر نتائج الأس الهيدروجيني لسائل الكرش قبل التغذية ولا بعد التغذية بساعتين ولا تركيز أمونيا سائل الكرش بعد التغذية بساعتين على وجود فروق معنوية ما بين المعاملات الأربعة، أما تركيز الأمونيا لسائل الكرش قبل التغذية فقد أشار إلى وجود تفوق معنوي (P≤ 0.05) في المعاملة الرابعة مقارنة بالمعاملات الأخرى. كذلك لم يلاحظ وجود فروقات معنوية في صفات الدم. الكلمات المفتاحية: الزعتر البري – الحملان العواسية – النمو – صفات الذبيحة – التغذية.
