Caracterização química e perfil aminoácidico da farinha de silagem de cabeça de camarão

Abstract

The growing development of the fishery forced the researchers they to look for the best form of use of the rations, because these, they can elevate the cost of production from 50 to 80%. In the diets for fish and shrimps, the protein of animal origin more commonly used it is together the bone flour and meat with the fish flour. Due to shortage and the high price of such sources proteins and seeking the flour if silage of shrimp head as an alternative in potential, that research had as objectives the elaboration, chemical characterization and the profile of the amino acids of the flour of silage of shrimp head, seeking to assist the demands nutritionals of amino acids in the feeding of fish. The experiment was driven in the Laboratory of Development of Fishing Products - LDFP - of the Department of Technology and Chemistry of Foods, UFPB. The flour of silage of shrimp head was elaborated and accomplished the chemical analysis (centesimal composition) and dosage of calcium and match, accomplished in triplicate. The analysis of the composition of amino acids of the silage of shrimp head was accomplished in a High-Performance Liquid Chromatography. The flour of silage of shrimp head was shown as an excellent source proteins (39,5%) and lipids (12,5%) besides having considerable amount of calcium, therefore it can serve as eventual substitute in the formularization of diets for fish.
