چکیده

در این مطالعه الگوی مصرف انرژی، کارایی و درصد ذخیره انرژی برای مرغداری­های مرغ گوشتی سه شهرستان اصفهان، نائین و نجف­آباد با ظرفیت­های مختلف مورد بررسی قرار گرفت. میانگین کل افزوده خالص انرژی برای ظرفیت­های کمتر از 10 هزار، 10 تا 30 هزار و بیشتر از 30 هزار قطعه به ترتیب 66/143-، 58/129- و 99/94- گیگاژول بر هزار قطعه مرغ به دست آمد. کارایی فنی برای ظرفیت­های کمتر از 10 هزار، 10 تا 30 هزار و بیشتر از 30 هزار قطعه به ترتیب 88، 92 و 96 درصد برآورد گردید. کارایی فنی خالص به ترتیب ظرفیت­ها 97، 98 و 99 درصد به دست آمد. انرژی ورودی بهینه­سازی شده توسط مدل بازگشت به مقیاس متغیر به ترتیب برای ظرفیت­های کمتر از 10 هزار، 10 تا 30 هزار و بیشتر از 30 هزار قطعه برابر 90/146، 80/136و 77/117 گیگاژول بر هزار قطعه مرغ به دست آمد.

چکیده [English]

In this study, energy consumption pattern, efficiency and the percentage of saved energy and inputs of poultry production farms in Isfahan, Nain and Najafabad townships with different capacities were evaluated. The average of net energy gain per 1000 bird for capacities less than 10, 10-30 and more than 30 thousand pieces was calculated as -143.66, -129.58 and -94.99 GJ/1000 bird, respectively. Technical efficiency for different capacity groups was 88, 92 and 96 %, respectively, and pure technical efficiency was 97, 98 and 99 %, respectively. The optimized input energy by the returns to variable scale model for capacities less than 10, 10-30 and more than 30 thousand pieces was 146.90, 136.80 and 117.77 GJ/1000 birds, respectively.
