چکیده مقاله :

A feeding trial was conducted to assess the effect of inclusion of ensiled sugarcane waste (ESCW) with poultry litter on performance of Yankasa rams in a completely randomized design (CRD) for twelve weeks (84 days). Sugarcane waste was mixed with poultry litter in 3:1 and ensiled for 21 days. The ESCW was used as partial replacement in complete diet. Sixteen Yankasa rams (mean body weigh 28.94 ± 5.77 kg and aged 12 to 18 months) were allotted to the four groups on the basis of body weights into control group without ESCW (CG) or control diets as treatment groups (TGs) partially replaced with ESCW at 15% (TG1), 30% (TG2) or 45% (TG3). Diets were offered ad libitum, along with clean drinking water and mineral salt lick at will. The results showed no significant (P>0.05) differences in the treatment means of all the growth parameters evaluated, values recorded for TG3 (45%) were numerically higher in final live weight, weight gain and average daily gains (ADG). Significant (P<0.05) differences were recorded in dry matter and ash intakes while the dry matter, crude fibre and ash apparent digestibility differed significantly (P<0.05) among the CG and TGs. In conclusion, performances of Yankasa rams with 45% inclusion of ESCW were comparable to CG and its usage is therefore recommended as alternative choice during the lean periods based on the observed nutritional facts.

چکیده انگلیسی:

یک آزمایش تغذیه­ای با هدف بررسی اثر وارد کردن بقایای نیشکر سیلو شده (ESCW) همراه با کود مرغی بر عملکرد قوچ­های یانکا در قالب یک طرح کاملاً تصادفی (CRD) به مدت 12 هفته (84 روز) صورت گرفت. بقایای نیشکر با کود مرغی به نسبت 3 به 1 مخلوط شده و به مدت 21 روز سیلو گردید. ESCW به عنوان بخشی از جیره جایگزین گردید. 16 قوچ یانکا (میانگین وزن 77/5±94/28 کیلوگرم در محدوده سنی 12 تا 18 ماهگی) در چهار گروه بر مبنای وزن بدن (گروه کنترل بدون ESCW (CG) و جیره­ها یا گروه­های تیماری (TG ها) که بخشی از جیره با 15 درصد (TG1)، 30 درصد (TG2) و 45 درصد (TG3) جایگزین شده بودند) تخصیص داده شدند. جیره­ها به صورت اختیاری همراه با آب آشامیدنی تمیز و نمک معدنی لیسیدنی در دسترس حیوانات قرار گرفتند. نتایج نشان داد که هیچ­گونه تفاوت معنی­داری بین میانگین تیمارها برای پارامترهای رشد وجود نداشته (05/0<P) ولی مقادیر ثبت شده برای TG3 (45 درصد) از نظر عددی در وزن زنده و افزایش وزن پایانی و میانگین افزایش وزن روزانه (ADG) بالاتر از سایر تیمارها بوده است. تفاوت ثبت شده در ماده خشک و خاکستر مصرفی معنی­دار بوده (05/0>P) و تفاوت ماده خشک، فیبر خام و قابلیت هضم ظاهری خاکستر بین CG و TG ها معنی­دار بوده است (05/0>P). از این مطالعه می­توان نتیجه گرفت که عملکرد قوچ­های یانکا با در نظر گرفتن 45 درصد ESCW در جیره قابل مقایسه با CG بوده و بنابراین کاربرد آن به عنوان جایگزین در طی دوره پروار بر مبنای حقایق تغذیه­ای مشاهده شده، توصیه می­گردد.
