Abstract
The aim of study was to compare effective dry matter degradation (EWRdm) and rumen degradability of three lucerne cultivars: domestic Kometa, French Luzelle and American Legend. Field experiment was carried out at the Agricultural Experimental Station IUNG Grabów in 1999–2000. The plant materials from the first cutting, collected in different development stage were evaluated with “in sacco” method. Lucerne Kometa cv. showed the maximum value of effective dry matter degradation (EWRdm) and highest rumen degradability. The delay of first cutting of lucerne plants, reduced EWRdm data. The quickest aging of lucerne occurred at budding period.
