1 Each value represents the mean of four replicates. nd—not determined. 2 Starch wasn’t determined because the content of this compound in lupins is very low (around 1%) and the reliability of results is arguable 3 RTO—raffinose type oligosaccharides. NDF—neutral detergent fiber; ADF—acid detergent fiber.
