Abstract

The present study investigated the effects of total replacement of dietary fish oil by different vegetable oils on growth performance, nutritional quality and fatty acid profiles of rainbow trout (Oncorhynchus mykiss) at optimum and high temperature conditions. Five iso-nitrogenous and iso-lipidic diets including 100% fish oil and vegetable oils were prepared for rainbow trout fingerlings with an average weight of 11.27±0.01 g. After the fish were fed experimental diets for 9 weeks at the optimum temperature (17.74±0.01°C), all groups were fed an FO diet containing only fish oil for 4-weeks at the upper optimum temperature conditions (19.28±0.11°C). In both feeding trials, experimental fish were hand-fed ad libitium twice a day. Results showed that growth performance and feeding efficiency were significantly better (p

Özet

Bu çalışmada, balık yağının farklı bitkisel yağlarla toplam ikamesinin, optimum ve yüksek sıcaklık koşullarında gökkuşağı alabalığının (Oncorhynchus mykiss) büyüme performansı, beslenme kalitesi ve yağ asidi profilleri üzerindeki etkileri araştırılmıştır. Ortalama 11,27±0,01 g ağırlıktaki gökkuşağı alabalığı yavruları için %100 balık yağı ve bitkisel yağlardan oluşan beş izo-nitrojenli ve izo-lipidik diyet hazırlanmıştır. Balıklar optimum sıcaklıkta (17,74±0,01°C) 9 hafta deneysel diyetlerle beslendikten sonra, tüm gruplara optimum üstü sıcaklık koşullarında (19,28±0,11°C) 4 hafta boyunca sadece balık yağı içeren bir FO (kontrol) diyeti verilmiştir. Her iki besleme denemesinde de deneysel balıklar günde iki kez elle doyuncaya kadar beslenmiştir. Sonuçlar, optimum sıcaklıkta FO bazlı diyetle beslenen gruplara kıyasla, VO bazlı diyetlerle beslenen gruplarda büyüme performansı ve yemleme veriminin önemli ölçüde daha iyi (p
