Replacing moringa leaf (Moringa oleifera) partially by protein replacement in soybean meal of fancy carp (Cyprinus carpio)

Abstract

Moringa oleifera Lam (Moringaceae) is a highly valued plant, distributed in many countries of the tropics and subtropics.The leaves are the protein source with an adequate profile of amino acids. The present study was undertaken in orderto determine the effect of a dietary of moringa leaves on digestibility and growth performance of fancy carp. Fish were fedwith diets containing isonitrogenouse and isoenergetic formulated by 20 and 50 g kg-1 of moringa leaves to replace protein insoybean. Fish were distributed in 500-liter tanks with flow-through water. Every fish was weighed and after the terminalexperiment, all groups’ livers and distal intestines were sampled. All fish grew normally (p>0.05) but fish fed with proteinreplacingmoringa leaves at 50 g kg-1 were noted to exhibit slightly poor growth performance and feed utilization. The studyindicated that the tested moringa leaf diet contains ingredients that could be used for fancy carp diets with possibly notover up to 20 g kg-1 soybean protein replacement without negative effect on growth and digestibility.
