چکیده

در این تحقیق اثرات تغذیه با پودر پوست موز به عنوان یک خوراک طبیعی و بیشتر با کاربرد دارویی بررشد،بقا و ترکیب شیمیایی ماهی کپورمعمولی (Cyprinus carpio) مورد بررسی قرارگرفت. تعداد 240عدد بچه ماهی کپور معولی با میانگین وزن57/3±00/19گرم و میانگین طول 48/0±61/10در چهار تیمار 15،10،5،0 درصد خوراک پوست موز و هر تیمار در سه تکرار،برای مدت 60 روز در 12 مخزن 135لیتری پلی اتیلنی مورد تغذیه قرار گرفتند. ماهی های هر تیمار در ابتدا، وسط و انتهای دوره بیومتری گردیدند و شاخص های رشد شامل ضریب رشد ویژه، درصد افزایش وزن، ضریب تبدیل غذایی، کارایی غذا، نسبت بازده پروتئین، فاکتور وضعیت، افزایش طول و وزن نهایی بین تیمارها مقایسه گردید.در پایان دوره،از هر تیمار10نمونه تصادفی فیله جهت سنجش ترکیبات شیمیایی نظیرکربوهیدرات، رطوبت،پروتئین،چربی،خاکستر و فیبر به آزمایشگاه ارسال گردید. در ارتباط با تأثیر پوست موز بر فاکتورهای رشد بین تیمارها اختلاف معنی دار مشاهده گردید .(p<0.05) بالاترین ضریب رشد ویژه (090/0±515/1) ،بالاترین نرخ کارایی پروتئین مربوط به تیمار(025/0±915/0) مربوط به 10درصد پوست موز بود.در ارتباط با ترکیب شیمیایی لاشه نیز بین تیمارها اختلاف معنی دار مشاهده گردید.(p<0.05)بالاترین میزان چربی (055/0±686/2)، بالاترین میزان کربوهیدرات (081/0±830/0) مربوط به تیمار شاهد بود. بالاترین میزان فیبر (011/0±213/0) در 15درصد مشاهده شد.بالاترین میزان خاکستر (073/0±493/2)، بالاترین میزان رطوبت در تیمار (056/0±606/74)، مربوط به 10درصد مشاهده گردید.میزان بقا در بین تمام تیمارها 100درصد بود.

چکیده [English]

This experiment was undertaken on Cyprinus carpio (mean body weight 19/000±3/570) to study the effect of Banana peel powder on growth, survival and body composition. Two hundred forty juveniles were randomly distributed into 4 treatments each with three replicates and reared in 135 liter tanks for 2 month. Three experimental treatments were fed with Banana peel powder supplemented diet at three different concentration (5, 10, 15 %) control group were feed with non –supplemented diets. At the end of treatments following growth parameters condition factor, specific growth rate, relative growth rate, weight gain ,length gain, food conversion ratio ,protein efficiency ratio were measured .Chemical properties of fillet including the amount of fat, crude protein, fiber, carbohydrate, ash and moisture were measured before and at the end of treatment. . Results show that there was significant effect on specific growth rate (1.515±0/090)and protein efficiency ratio (0.915±0/010) among fish fed with Banana peel powder supplemented diet at 10% and that of the control(p<0.05). According to the chemical properties, significant difference was observed between all experimental groups and control group (p<0.05). Fish fed with Banana peel powder supplemented diet at 5% had the highest value of fat (2.230±0.111) and carbohydrates (0.830±0.081) between all treatments. The highest value of protein (20.550± 0.065).ash (2.493±0.119) and moisture (0.213±0.011) was recorded for fish that were fed with Banana peel powder supplemented diet at 15%. The survival rate was recorded 100% in all experimental and control treatments.
