Abstract

This study was conducted to evaluate the effect of using exogenous digestive enzymes(Zymogen®) and heattreatment of soybean (cooked)in diets on growth performance and feed efficiency of Nile tilapiaOreochromisniloticus(4.07g). Six experimental diets were formulated to be isonitrogenous (27% crude protein) and isocaloric(4.29kcal/g) and used to feed triplicate groups of fish to apparent satiation for11weeks. Treatments were: T1 contain both fish meal and plant protein sourcesas FMcontrol diet (FM), T2 contain only plant protein additivesas a SBMcontrol diet, T3 (SBM +1.0% zymogen) Z1, T4 (SBM +2.0% zymogen)Z2, T5 and T6 (SBM +1.0% or2.0% zymogen levelwith cookedsoybean treatment)Z1C, Z2C respectively.Results showed that supplemented fish diets with zymogen and cookedsoybean enhanced fish performance over plant diet control. Fish maintained atFM,Z2, Z2Cand Z1Cdiets were significantly higher (P<0.05) in all growth performance parameters andsurvival rate values than other treatments.Differences among FM, Z2, Z2C and Z1C treatmentswere not significant (P>0.05). Also, feed efficiency parameterswere improved significantly(P<0.05)atfish maintained on FM, Z2Cand Z1Cdiets. These results suggest that using exogenous digestive enzymes (zymogen) and cooked soybean treatment in all plant based dietsmayenhancethe growth performance and the feed efficiencyof Nile tilapia. Moreover, theeconomicefficiency in terms of feed utilization has been improved
