The objective of this study was to analyze the centesimal composition of Eichhornia crassipes and Lemna minuta, as well as to evaluate their yields of carbohydrate extraction, aiming the application of their biomasses to animal feed. For the centesimal composition of the raw material, the percentages of moisture, minerals, proteins, cell wall fraction, lipids and soluble carbohydrates were evaluated. The results obtained in the biomass composition of E. crassipes revealed 8.48% crude protein and 68.45% cell wall fraction. For L. minuta, 14.95% crude protein and 53.43% cell wall fraction were obtained. For moisture, ash, crude protein, cell wall fraction and lipids there was a statistically significant difference between the species. For the yield of carbohydrate extraction, an average of 0.83% was found for L. minuta, this value being lower than that obtained for E. crassipes (2.65%). The evaluation of the centesimal composition and the carbohydrate extraction of the biomasses of E. crassipes and L. minuta was carried out and the results obtained for the protein and fiber levels showed that the biomasses of these species can be used in animal feed.
