The effect of bromelin in artificial feed on feed utilization efficiency, growth, and survival of gourami seeds (Osphronemus goramy)

Abstract

The relatively slow body growth of gourami (Osphoronemus goramy) compared to other fish can be overcome by adding bromelain to the feed. The research aims to determine the effect of bromelain on feed utilization efficiency, protein efficiency ratio and seed growth rate. The research was conducted at the Muntilan Loka for 42 days using gourami seeds measuring 7.92±0.18 cm with a weight of 7.36±0.34g. The research used an experimental method with a completely randomized design consisting of 4 treatments with 3 replications, namely treatments A, B, C, D with doses of 0; 0.75; 1.50; and 2.50g/kg feed. The results showed that bromelain had a significant effect (p0.05) on the TKP and SR variants. The optimum dose of bromelain for gourami seeds is 1.49-2.37g/kg feed and produces a maximum EPP value of 76.47%, PER 1.63% and RGR 4.81%/day.
