Composição bromatológica e digestibilidade aparente da parte aérea seca da mandioca na alimentação de tilápias-do-nilo

Abstract

Resumo -O objetivo deste trabalho foi avaliar o efeito da secagem da parte aérea da mandioca, ao sol e à sombra, sobre a composição bromatológica e o coeficiente de digestibilidade aparente (CDA) de nutrientes, energia e aminoácidos para tilápia-do-nilo (Oreochromis niloticus). Não houve diferença entre os métodos de secagem para a composição bromatológica. O CDA da proteína bruta apresentou maior digestibilidade para a parte aérea seca à sombra. A secagem da parte aérea da mandioca à sombra permite maior conservação do conteúdo proteico e melhor digestibilidade aparente da fração proteica e aminoacídica para a tilápia-do-nilo.Termos para indexação: Manihot esculenta, Oreochromis niloticus, alimento alternativo, aminoácidos, secagem. Chemical composition and apparent digestibility of dried aerial part of cassava in Nile tilapia feedingAbstract -The objective of this work was to evaluate the effect of sun and shade drying of the aerial part of cassava on the chemical composition and apparent digestibility coefficient (ADC) of nutrients, energy, and aminoacids for Nile tilapia (Oreochromis niloticus). There was no difference between the drying methods for chemical composition. The ADC of crude protein showed higher digestibility for the shade dried aerial part. Shade drying of the aerial part of cassava allows higher conservation of the protein content and better apparent digestibility of the protein and amino acid fraction for Nile tilapia.

Proximate and fatty acid compositions oft en wild‐caught and farmed fish species in mato grosso state, brazil

“…[11,12] Despite the considerable increase in the supply and consumption of freshwater fish, the Brazilian population has little knowledge about their chemical and nutritional properties, especially regarding native fish species from Brazilian rivers. [13,14] Inhabitants of northern Brazil, residing in a sparsely populated and geographically challenging region, heavily rely on fish as a primary source of protein. Ensuring food security in this area necessitates an increased understanding of the local fish species.…”

INCLUSION OF MESQUITE POD MEAL (<i>Prosopis juliflora</i>) IN DIETS FOR NILE TILAPIA (<i>Oreochromis niloticus</i>) JUVENILES

“…In order for an alternative feed to be considered industrially viable, it must be low cost, high volume of production, regionally or nationally available and increase growth performance of fish (Glencross et al, 2007). In addition, the importance of the extensive knowledge of nutritional characteristics, nutrient digestibility and evaluation of the presence of antinutritional 2/9 factors are of fundamental importance (Boscolo et al, 2011;Hisano et al, 2013;Bosisio et al, 2017).…”
