Abstract

This experiment was conducted to evaluate the effect of dietary centaury oil (Hypericum perforatum) on growth performance, some environmental stress parameters and antioxidant activity in juvenile rainbow trout (Oncorhynchus mykiss). The Experiment, conducted in 500 litre rectangle fiberglass tanks for 90 days, was performed in replicate groups and all tanks were stocked with 35 juveniles (initial mean weight 20g). Experimental feeds were formed as K0 (control group without centaury oil inclusion), KT1 (1 mL/kg), KT2 (2 mL/kg) and KT3 (3 mL/kg) centaury oil supplements. At the end of the trial parameters were obtained as; weight gain 88,86-90,97 (gr), specific growth rate 1,85-1,86 (% day-1), feed conversion rate 1,02-1,07, survival rate 97-100%, feed conversion efficiency 98,89-100,05, contidion factor 1,23-1,24, total antioxidant status 1,962,07(µmol Trolox equivalents/L), total oxidant status 1,10-1,70(µmol H2O2 equivalent/L), oxidative stress index 56,15-81,44, glucose status 73,00-76,66, cortisol status 0,78-1,13, lysozyme zone diameter 0,90-1,08 (cm). Feed groups showed statistical difference in terms of total oxidant status and oxydative stress index parameters (p0.05) but possitive effects upon oxydant status and oxydative stress index were observed.

Özet

Bu çalışmada jüvenil gökkuşağı alabalığı (Oncorhynchus mykiss) yemlerine ilave edilen sarı kantaron (Hypericum perforatum) yağının büyüme performansı, bazı çevresel stres parametreleri ve antioksidan aktivitesi üzerine etkileri araştırılmıştır. Çalışma 0 mL/kg (kontrol grubu) ve 1 mL/kg, 2 mL/kg, 3 ml/kg oranlarında kantaron yağı içeren yem grupları ile 3 tekerrürlü olarak oluşturularak 500 litrelik dikdörtgen fiberglas tanklarda 20g ortalama başlangıç ağırlığına sahip jüvenil alabalık bireyleriyle 90 gün boyunca sürdürülmüştür. Deneme sonucunda elde edilen parametrelerden, toplam ortalama canlı ağırlık artışı 88,86-90,97 (g), spesifik büyüme oranı 1.85-1.86 (% gün-1), yem dönüşüm oranı 1.02-1.07, yaşama oranı %97-100, yem dönüşüm etkinliği 98.89-100.05, kondisyon faktörü 1.23-1.24, total antioksidan düzeyi 1.96-2.07 (µmol Trolox equivalents/L), total oksidan düzeyi 1,10-1,70 (µmol H2O2 equivalent/L), oksidatif stres indeksi 56.15-81.44 (TOS/TAS*100), glikoz düzeyi 73.00-76.66 (mg/dL), kortizol düzeyi 0.78-1.13 (µ/dL), lizozim enziminin oluşturduğu zon çapı 0.90-1.08 (cm) aralıklarında belirlenmiştir. Yem gruplarının total oksidan düzeyi ve oksidatif stres indeksi parametreleri istatistiksel açıdan farklılık göstermiştir (p0.05) oksidan düzeyi ve oksidatif stres indeksi düzeylerinde olumlu etkiler gözlenmiştir.
