Using adapted methods for balanced experiments with waterfowl, the content and the true digestibility of the amonoacids of hull-less barley have been established. The following contents of the essential amonoacids of a stocking lot of the forage have been established (g/kg DM): lysine-4.8, methionine-1.1, cystine-1.1, histidine-2.2, threonine-4.4, leucine- 6.8 and phenylalanine- 5.9. The coeffi cients of their true digestibility were 81.89, 84.06, 85.08, 90.62, 87.30, 76.38 and 75.96, respectively.
