چکیده مقاله :

The objectives of the study were to evaluate the effects of Sabara leaf meal on growth performance, nutrient digestibility and haematological parameters of red Sokoto goats. Bucks were managed in a complete randomized design with 4 treatments and 3 replicates. The Sabara leaf meal (SLM) was fed at concentration of 0, 10, 20 and 30% in treatment 1, 2, 3 and 4 respectively. The experimental diets and clean drinking water were offered to the animals ad libitum. Initial body weights were all similar. Bucks fed diets with 10 and 20% Sabara leaf meal (SLM) gained weight (P<0.05) faster than those fed the control diets. Feed intake differ significantly (P<0.001) among the groups. T4 recorded superior feed intake compared to T1, T2 and T3. Body weight and feed conversion ratio (FCR) increased with levels of Sabara leaf meal (SLM) in the diets up to a point (T3) with bucks on 20% Sabara leaf meal (SLM) being heavier. The metabolizable energy (CP), crude fibre (CF), ether extracts (EE) and nitrogen free extract (NFE) digestibilities also differed significantly (P<0.05) among the treatments. Similarly, the DM, CF, CP and EE digestibilities of T3 were superior to the control (T1).Hemoglobin(Hb), mean corpuscular volume(MCV), mean corpuscular hemoglobin (MCH) and platelets differed (P<0.05, P<0.01) among treatments. However, packed cell volume (PCV), red blood cells (RBC), white blood cells (WBC) and mean corpuscular hemoglobinconcentration (MCHC) were not significantly (P>0.05) affected. The white blood cells differentials were slightly different between treatment groups but all remains within the reference range. The results of this study indicated that Sabara leaf meal could be used as feed resources to raise goats. The levels of least Sabara leaf meal (SLM) from 20 to 30% gave high growth performance and better benefits without adverse effect on biological performance. More research is needed to evaluate Sabara leaf meal on growth performance and nutrient utilization by goats.

چکیده انگلیسی:

هدف این مطالعه بررسی اثرات پودر برگ سابارا بر عملکرد رشد، قابلیت هضم مواد مغذی و پارامترهای خون بز سوکوتو سرخ بود. بزها در قالب طرح کاملأ تصادفی با 4 تیمار و 3 تکرار قرار گرفتند. پودر برگ سابارا (SLM) در غلظت 0، 10، 20 و 30 درصد به‌ ترتیب در تیمار 1، 2، 3 و 4 تغذیه می‌شد. جیره‌های آزمایشی و آب آشامیدنی در حد اشتها به حیوانات ارائه شدند. وزن اولیه بدن همه مشابه بود. بزهایی که جیره غذایی با 10 و 20 درصد SLM سریع‌تر از آنهایی که با جیره غذایی کنترل تغذیه شدند افزایش وزن داشتند (05/0>P). مصرف غذا در میان گروه‌ها تفاوت معنی‌داری داشت (001/0>P). تیمار 4 در مقایسه T1 ، T2 و T3 مصرف غذای بیشتری داشت. وزن بدن و ضریب تبدیل غذایی (FCR) با افزایش سطح SLM در جیره غذایی افزایش یافت تا نقطه تیمار 3 و بزهای تغذیه شده با 20 درصد SLM سنگین‌تر بودند. قابلیت هضمCP ، CF ، EE وNFE  نیز در میان تیمارها اختلاف معنی‌دار داشت (05/0>P). به طور مشابه، قابلیت هضم DM، CF ، CP و EE در T3 نسبت به شاهد (T1) بهتر بود. هموگلوبین، MCV، MCH و پلاکت‌ها در میان تیمار‌ها متفاوت بودند (05/0>P، 01/0>P) . با این‌حال،PCV ، RBC، WBC و MCHC اختلاف معنی‌داری نداشتند (05/0<P). سلول‌های سفید خون در دو گروه تیماری تفاوت داشتند اما همگی در محدوده مرجع باقی ماندند. نتایج حاصل از این مطالعه نشان داد که جیره غذایی برگ سابارا می‌تواند به‌ عنوان منابع غذایی برای پرورش بز استفاده ‌شود. سطح SLM از 20 تا 30 درصد رشد بالا و مزایای بهتر و بدون اثر سوء بر عملکرد بیولوژیکی داشت. تحقیقات بیشتری برای ارزیابی جیره غذایی برگ سابارا بر عملکرد رشد و مصرف مواد مغذی توسط بز مورد نیاز است.
