HUNT, ARZU ÖZLÜER | Yılmaz, Ferbal Özkan

The present study was conducted to study the effect of fish oil (FO) and cod liver oil (CLO) as the dietary lipid sources on the growth performance, feed utilization and fatty acid (FA) composition of Oreochromis niloticus. Two isonitrogenous (38% crude protein), isocaloric (18.9 MJ GE/kg) diets containing 8% lipid were formulated. Each diet was fed to triplicate groups of 17 fish with a mean initial body weight of 18.18 ± 0.02 g. Fish were fed with %3 of their body weight two twice daily. The fish were kept at 28±1 °C in 6 square experimental cages (1×1×1.25 m) for 60 days. Results revealed that the source of lipid significantly affect (P
