The Effects of Using Peanut Meal in Rainbow Trout (Oncorhynchus mykiss) Diets on the Growth Performance and Some Blood Parameters

Abstract

In this trial, rainbow trouts (71.69±1.21 g) were fed with feeds containing peanut mealat different levels for 60 days and their growth performance, body compositions and someblood parameters were examined. Accordingly, 4 different trial feeds as the control feed(PNM0) that contains FM as the main source of protein, and feeds containing 10% (PNM10),20% (PNM20) and 30% (PNM30) peanut meal as an alternative to fishmeal were prepared.At the end of the feeding period, fish that were fed with PNM10 gained as much weight asthose fed with the control feed. Feed conversion ratio (FCR) and specific growth rate (SGR)findings of rainbow trouts fed with trial feeds differed significantly from the control group asthe peanut meal level used in feeds exceeded 10% (P0.05). In the examination of thehematological parameters obtained from rainbow trouts fed with feeds containing differentpeanut meal levels, it was detected that there were no significant differences compared tothe control group (P
