چکیده

مطالعه حاضر به منظور بررسی اثرات سیتریک اسید بر عملکرد رشد و شاخص های خونی بچه ماهی قرمز (Carassius auratus) به مدت 60 روز انجام گرفت. بچه ماهیان (با میانگین وزن اولیه 0/16±7/10 گرم) در یک طرح کاملا تصادفی به 4 تیمار آزمایشی و 3 تکرار (25 قطعه در هر تانک) تقسیم شدند. تیمارها شامل شاهد (بدون استفاده از سبتریک اسید) و مقادیر 1، 2 و 3 درصد سیتریک اسید به ازای هر کیلوگرم جیره، بود. نتایج حاصل از این آزمایش نشان داد که شاخص های رشد شامل: وزن نهایی، افزایش وزن، نرخ رشد ویژه و شاخص وضعیت در تیمارهای حاوی سیتریک اسید افزایش معنی داری نسبت به گروه شاهد داشته است (0/05>p). هم چنین بررسی شاخص های خونی در تیمارهای آزمایش نشان داد که تعداد گلبول قرمز، میزان هموگلوبین و هماتوکریت در تیمارهای حاوی سیتریک اسید افزایش معنی داری نسبت به گروه شاهد داشته است (0/05>p). در کل، نتایج این مطالعه نشان داد افزودن سیتریک اسید به جیره غذایی به میزان 2 گرم در هر کیلوگرم جیره غذایی بچه ماهی قرمز سبب بهبود شاخص‌های رشد و شاخص های خونی گردید.

چکیده [English]

The effects of citric acid on the growth and blood indices of goldfish fry (Carassius auratus) were examined in a 60-day period. The goldfish fries (with initial weight of 7.10±0.16 g) were randomly categorized into four experimental treatments with three replications (25 fish/tank). The treatments included a control three groups of 1, 2, and 3 g citric acid per each kilogram of food ration. The results indicated that the growth parameters: The final weight, weight increase, specific growth rate, and condition factor in the citric acid groups had a significant increase compared to the control group (P<0.05). In addition, blood indices in the experimental treatment indicated that the red blood cell count and hemoglobin and hematocrit levels in the citric acid treatments had a significant increase compared to the control group (P<0.05). In general, adding citric acid at 2 g/kg of the diet of goldfish fry improved the growth parameters and blood indices.
