Farelo de babaçu em dietas para tambaqui Babassu meal in diets for tambaqui

Abstract

Realizou-se este trabalho com o objetivo de avaliar o desempenho produtivo, rendimento de carcaça e filé, composição química da carcaça, peso dos órgãos do sistema digestório, comprimento relativo de intestino, bem como os índices hepato-somático e de gordura víscero-somática de 120 juvenis de tambaqui (Colossoma macropomum), alimentados com dietas contendo 0, 6 ou 12% de farelo de babaçu. Não foi observada influência da inclusão do farelo de babaçu nas dietas sobre o desempenho produtivo, rendimento de carcaça e filé dos juvenis de tambaqui, bem como para a composição da carcaça. Para as variáveis do trato digestório, não foram observadas diferenças para o peso das vísceras, para o índice de gordura viscero-somática e para o comprimento relativo do intestino. Houve redução no índice hepato-somático à medida que ocorreu aumento da inclusão do farelo de babaçu nas dietas, possivelmente em resposta à ação de algum fator antinutricional presente no ingrediente. Conclui-se que o farelo de babaçu pode ser considerado na composição das dietas de juvenis de tambaqui até 12% de inclusão.The aim of this work was to evaluate the performance, dressing and fillet percentage, carcass composition, weight of organs of digestive tract, relative intestine length and hepatica-somatica and viscera-somatica fat indexes of 120 tambaqui (Colossoma macropomum) fingerlings fed with diets with 0, 6 or 12% of babassu meal. Babassu meal inclusion did not affect the performance, dressing and fillet percentage and carcass composition. Gastrointestinal tract weight, viscera-somatic fat index and relative intestinal length were not affected, although hepatica-somatic index was reduced with increasing levels of babassu meal, possibly due to an antinutritional factor in the feed. In conclusion, babassu meal might be added in fingerlings tambaqui diets at level of 12% of inclusion.
