Study of Avocado Seed and Banana Peel Processing as Corn Element Substitution in Japanese Quail (Coturnix-Coturnix Japonica) Ration

Abstract

This study aims to use avocado seeds and banana peels processed into rations to replace the use of corn by utilizing agricultural waste so that it can also reduce feed costs. This research consists of 3 stages of experiments, namely, experiment 1: processing avocado seed flour and banana peel flour to improve its quality. Experiment 2: the results of stage 1 research were carried out direct biological tests to livestock to see digestibility, stage 3 research: application of avocado seed and banana peel-based rations to quail. The results showed that Avocado Seed Processing (ASP) through soaking with 30% Husk Ash Water Filtrate (HAWF) for 48 hours can reduce tannin content in seeds by 42.86%, but crude protein content decreased by 37.53% and increased nitrogen retention by 57.62%. Fermentation of Banana Peel (FBP) using EM4 at a dose of 15mL/100g and fermentation duration of 6 days can reduce 15.54% of crude fiber content and increase crude protein content by 31.12% and increase crude fiber digestibility by 380%. It was concluded that the ration that gave the best response on performance and egg quality was ration C (20% FBP) and F (5% ASP + 15% FBP) so that it could reduce the use of corn by 44%.
