Abstract :

هدف از این مطالعه تعریف اهداف اصلاحی و شاخص انتخاب مناسب برای بز کرکی رایینی توسط شبیه‌سازی رایانه­ای بود. معیار انتخاب برای افزایش تولید شیر، گوشت و کرک در این نژاد وزن بدن بز ماده (BWD)، وزن شیر تولیدی (MW)، وزن کرک تولیدی (CW)، وزن بزغاله برای فروش (WK) و تعداد بزغاله برای فروش به ازای هر بز ماده بودند. چهار شاخص انتخاب (I1–I4) جهت مقایسه پیشرفت ژنتیکی برای صفات موجود در شاخص انتخاب تشکیل گردید. بیشترین پیشرفت ژنتیک در شاخص انتخاب کامل (I1) با نسبت بز نر 4/0 برآورد گردید. بنابراین مناسب ترین شاخص انتخاب در این نژاد شاخص انتخاب 1 شامل صفات وزن بدن بز ماده، وزن شیر تولیدی، وزن کرک تولیدی، وزن بزغاله برای فروش  و تعداد بزغاله برای فروش به ازای هر بز ماده می­باشد.
