The addition of Mucuna pruriens seed extract with different dosage on feed conversion ratio and feed efficiency of Rasbora argyrotaenia

Abstract

Abstract The objectives of this research were: 1) determine the effect of feed supplementation using velvet beans (Mucuna pruriens) seed extract with different doses on the feed conversion ratio and feed efficiency of silver barb (R. argyrotaenia), 2) determine the optimal dose of feed supplementation using velvet beans seed extract in silver barb on the value of feed conversion ratio and feed efficiency. This research used an experimental method with a completely randomized design consisting of five treatments of commercial feed without any addition (P0), 0.1 ml/kg velvet beans seed extract addition (P1), 1 ml/kg velvet beans seed extract addition (P2), 10 ml/kg velvet beans seed extract addition (P3), 35 ml/kg velvet seed beans extract addition (P4) in four replication for each treatments. The results of the supplementation with a different concentration of velvet beans seed extract addition showed significant difference (P < 0.05) on the specific growth rate, feed conversion ratio, and feed efficiency of R. argyrotaenia. The highest efficiency and feed conversion ratio of the supplementation of R. argyrotaenia feed obtained from addition of 0.1 ml/kg velvet beans seed extract.
