Lucerne is the most important source of protein, fiber, and mineral substances in ruminant nutrition. The objective of this study was to chemically analyze the new lucerne cultivars for the levels of protein, fiber, oil and mineral substances during the year (4 cuts). According to the results, the cultivars differed significantly in their crude protein, fiber, and mineral matter contents. The crude protein content was significantly higher in the first cutting than in the others, while the fiber content was significantly increased in the second and third cuts, i.e. in the warmest part of the year. The P and K contents were the highest in the first and the lowest in the fourth cutting, while the Ca and Na levels did not vary significantly over the year.
