LUTSERNI SEGUKÜLVI BOTAANILISE KOOSSEISU MÕJU ROHUSÖÖDA KVALITEEDILE
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. The PBV was decreased close to zero in the
`Karlu`/`Molisto`, `Karlu´/`Darimo` and `Karlu`/`Lincoln` mixtures of the first cut. Hybrid lu-
cerne ´Karlu´ was more persistent in the mixtures compared to common lucerne ´FSG 408 DP´.
Keywords: crude protein (CP), dry matter digestibility (DDM), metabolizable energy (ME),
