چکیده
صنعت طیور یکی از بزرگ‌ترین و توسعه یافته ترین صنایع موجود در کشور است و بررسی میزان انرژی مصرفی در مرغداری یکی از مهم‌ترین مسائل در پرورش مرغ گوشتی می‌باشد. تحقیق حاضر به بررسی روند مصرف انرژی و میزان مصرف آن در واحد های پرورش مرغ گوشتی استان البرز می‌پردازد. نهاده‌های اصلی ورودی شامل خوراک مصرفی، سوخت (گاز و گازوئیل)، الکتریسیته، نیروی انسانی، ماشین‌ها و جوجه یک روزه گوشتی و نهاده‌های خروجی گوشت مرغ و فضولات بستر بودند. کل انرژی‌های ورودی و خروجی برای هزار قطعه مرغ به ترتیب 2/125 و 9/24 گیگاژول بدست آمد. شاخص‌های انرژی شامل کارآیی انرژی، بهره‌وری انرژی و انرژی ویژه به ترتیب 2/0، 019/0 کیلوگرم بر مگاژول و 55/52 مگاژول بر کیلوگرم بدست آمدند. سوخت مصرفی (گاز و گازوئیل) با 84/50 و خوراک مصرفی با 43/42 درصد بیشترین سهم و جوجه یک روزه با 39/0 و نیروی انسانی با 06/0 درصد کمترین سهم را در بین نهادهای ورودی به خود اختصاص دادند. سهم انرژی مستقیم 03/57% و سهم انرژی تجدید ناپذیر 93/99% از کل انرژی مصرفی تعیین گردید.
