ANALYSIS OF THE FERMENTATION PROCESS OF FISH SILAGE POWDER MADE FROM FISH WASTE AND PINEAPPLE WASTE FOR USE AS LIVESTOCK FEED: A REVIEW

Abstract

This study was conducted to determine whether spoiled fish market scraps (viscera) from pineapple discarded, and derived products could be used as components in the production of powdered fish silage. At various phases of the production process, these repulsive components include the head, fins, fish skin, peels, seeds, viscera, and leftover flesh. Fish waste and its derivatives can be used as a supplement to animal feed because they are high in protein, minerals, and vitamins. These are also used to supplement animals' protein requirements. Fish oil and protein hydrolysates both provide significant amounts of nitrogen and phospholipids in animal feed. Fish oil and protein hydrolysates both provide significant amounts of nitrogen and phospholipids in the animal feed industry. The fermentation of sugar and other substances collected from pineapple waste could result in the production of proteins from a single cell, enzymes, organic acids, and bacterial cellulose. The powdered acid and fermented fish silage had good digestion and were an excellent source of feed, as determined by proximate analysis, amino acid composition, total antioxidant levels, DPPH-inhibition rates, and in-vitro digestibility evaluations. The in vitro digestibility of acid and fermented fish silage powders, as well as the results of proximate analysis, amino acid composition, total antioxidants, DPPH-inhibition rates, and digestibility analyses, indicated their high digestibility and value as feed sources.
