The aim of this project will be to obtain knowledge on cultivation and agronomical treatment of selected, perspective varieties of white lupin (Amiga, Dieta, Zulika), suitable for cultivation in the Czech Republic. The economic rentability of the seed and green mass production in individual periods of growth (in one – month intervals) will be assessed in tested varieties of white lupin, in climatic and soil conditions of the Czech Republic, in 4 – year duration of this project. Both production and nutritive value of the green mass of selected varieties white lupin will be compared with respect to the possibility of the green mass conservation. The effect of dehulling of lupin seeds on the nutritive value and quality of protein of seeds will be evaluated. The expenses of dehulling will be assessed as well. On basis of knowledge of the nutritive value of seeds, new complete feed mixtures, energy – balaced, will be formulated, for poultry (broiler chickens, laying hens, ducks) and rabbits. In these fed mixtures, 50 % and 100 % of extracted soybeen meal will be replaced with ground lupin, prepared from dehulled or intact seeds of perspective white lupin varieties. These feed mixtures of optimal composition will be tested, both biologically in accredited experimental animal houses, and under pilot plant conditions.
