The aim of this investigation was to study the common lucerne (Medicago sativa, L) ´FSG 408 DP´ and hybrid lucerne (Medicago varia, HL) ´Karlu´-grass mixtures during the years 2007-09. The grasses used in the mixture were hybrid- ryegrass ´Molisto´, tall fescue ´Seine´, meadow fescue ´Darimo´, reed canarygrass ´Palaton´ and smooth bromegrass ´Lincoln´. Maturity stages were accompanied by significant changes in nutritive value: increased NDF, decreased CP, DDM, ME. Especially in the first cut the quality declines rapidly when the forage biomass increases. Dynamics of quality changes depended on the speed of species' seasonal development. Botanical composition of lucerne-grass mixtures showed positive correlation between percent of lucerne and CP (r = 0,73; p < 0,05) and negative correlation between percent of lucerne and NDF (r = -0,55; p < 0,01). The harvests of the lucernes had positive protein balance values (PBV) in the rumen
on aeglasem. Ristik säilitab rohusööda kvaliteedi pikemal perioodil, kuna ta areng on kõrrelistest aeglasem. Ainevahetusenergia muutuste erinevused õiepungade moodustumisest õitsemiseni puhas- ja segukülvide vahel on äärmuslikud. Tabel 7.
