UTILIZATION OF LIQUID WASTE OF CHITIN EXTRACT FROM SKIN OF SHRIMP PRODUCTS OF CHEMICAL AND BIOLOGICAL PROCESSING AS FEED SUPLEMENT AND ITS IMPLICATION ON GROWTH OF BROILER

Abstract

The aim of research for getting optimization of condition of process (doze of chemical or microbial and time of processing) on the stage of deproteination and demineralization as chemical and biological on protein and mineral liquefy from chitin extract. The product of chitin extract used as feed supplement for getting optimize level in ration on digestibility value and performance at broiler. The research conducted in three stages using experimental method at Laboratory. The first stage used Nested Design (3x3) consisted three replication. The second and third stage used Completely Randomized Design consisted eight treatments and four. Variables which examined in first stage were the contents of protein, calcium, and phosphor liquefy at liquid product of chitin extract; The second stage were digestibility of dry matter, protein, and organic matter; The third stage: consumption of ration, gain of body weight, and conversion of ration at broiler. The Results were analyzed by variance and deference of chitin extract of wasteshrimp as biological through deproteination processed with Bacillus licheniformis at doze 4% time 48 hour, and followed demineralization with Aspergillus niger at doze 2% time 48 hour result the best of protein and mineral liquefy. Liquid product of chitin extract as biological can be feed supplement, and were used about 3% in ration at broiler for result optimized digestibility value and performance.
