Addition of turmeric (Curcuma longo LINN) extract on artificial feed to increase feed eficiency and the growth of gouramy fry (Osphronemus goramy

Abstract

Artificial feed consisting of anting spinach flour (Acalypha indica L) and mung bean sprout waste (Vigna radiata) with the addition of turmeric extract is a fish feed that has not been widely used as a source of vegetable protein raw materials. This study aims to determine the effect of adding turmeric extract (Curcuma longa LINN) to the feed formula on increasing feed efficiency and growth of Osphronemus gourami. Materials and methods, the test fish used was gourami with an average individual weight of 5.04±0.5 g/head. Feeding at 08.00, 12.00 and 16.00 with feeding at satition. The test fish were reared with a stocking density of 13 fish/20 L, using a 30 liter bucket container with a maintenance period of 42 days. This research was conducted by experimental method using Completely Randomized Design (CRD) with 4 treatments and 3 replications. Each treatment contains 31.5-32.33% crude protein. The treatment is A: without spinach anting flour and bean spout flour, B: 100% spinach anting flour and 0% bean sprout flour, C: 50% spinach anting flour and 50% bean sprout pulp flour, D : 100% test feed of bean sprout pulp flour and each treatment was repeated three times. The treatment tested was the same dose of turmeric extract added to the feed with treatments A, B, C and D, each dose was given the same (15 ml/kg feed). The observed data included feed consumption rate (TKP), feed utilization efficiency (FUE), protein efficiency ratio (PER), feed conversion ratio (FCR), protein eficiency ratio (PER), net protein utilization (NPU), relative growth rate (RGR), survival rate ( SR) and water quality. The best EPP treatment was C 95.92±2.49%, and FCR value 1.67±0.03. PER value 3.00±0.077%. NPU value... The treatment with the best growth was treatment C, which was RGR 6.11±0.07%/day. The water quality in the rearing media was in the appropriate range for rearing the test fish.
