EFFECT OF FEED ADDITIVES ON GROWTH, SURVIVAL RATE AND FEED UTILIZATION OF CARP FINGERLINGS (Cyprinus carpio L.)

This study was carried out to assess the effect of different commercial feed additives on growth, survival rate and feed utilization of carp fingerlings. Three treatments were used, control, Toniphos and Periavit respectively. The experiment lasted for 45 days. The maximum growth was obtained with Toniphos and Periavit treatments respectively. On the other hand, the reduced growth was recorded at treatment with control. Generally, growth and feed conversion ratio were improved for carp fingerlings fed on diets with feed additives compared to fish fed on the control diet. Feed cost essential to make 1Kg weight gain compared to fish fed the control diet treatment was reduced by using feed additives (Toniphos and Periavit).These results indicated that using Toniphos at level of 0.1% was the greatest in terms of growth performance and economic evaluatio
