چکیده

هدف از این مطالعه بررسی اثر کاهش نسبت اسیدهای چرب امگا 6 به امگا 3 جیره طی دوره پس از زایش بر غلظت هاپتوگلوبین پلاسما، متابولیت‌های خونی و مقاومت به انسولین درگاوهای هلشتاین بود. تعداد 24 راس گاو چند شکم زا به‌طور تصادفی در سه تیمار با نسبت اسیدهای چرب امگا-6 به امگا-3: 5/2 به 1 (نسبت کم)، 5/4 به 1 (نسبت متوسط)، و 5/6 به 1 (نسبت زیاد) توزیع شدند. خونگیری در روز 7، 14، 28، 42، 56 و 70 پس از زایش به منظور تعیین غلظت متابولیت‌های خونی و هاپتوگلوبین انجام شد. تست تحمل گلوکز و چالش انسولین در روزهای 28 و 42 آزمایش انجام شد. غلظت پلاسمایی هاپتوگلوبین در گاوهای تغذیه ‌شده با نسبت زیاد امگا 6 به امگا 3 به‌طور معنی‌داری نسبت به دو تیمار دیگر بیشتر بود. تست چالش انسولین در روز 42 روز بعد زایش نشان‌داد که تغییر در نسبت اسیدهای چرب تیمار متوسط باعث افزایش نرخ زودگی و کاهش سطح زیر منحنی انسولین شد. نتایج این تحقیق گویای آن است که نسبت متوسط از اسیدهای چرب امگا-6 به امگا-3 در جیره گاوهای شیری باعث کاهش مقاومت به انسولین در اثر کاهش یکی از فاکتورهای التهابی می‌شود.
