Description	This paper presents the results of tests of voluntary dry matter intake (VI) of silages made from grasslands with different intensity of utilization in 2010. Grasslands were managed in this way: medium intensive utilization (3 cuts per year, N90P30K60 per year); low intensive utilization (2 cuts per year, N90P30K60 per year); and extensive (control) utilization (2 cuts per year, nil-fertilization). The experiment was conducted on 2x6 heifers from the Low Input system using 2 types of housing: loose box housing (using feeding troughs – Roughage Intake Control (RIC)) and tie-stall housing (manual feeding). VI was influenced by intensity of grassland management (increasing intensity of use increased VI) and also by the housing system. Our results confirmed higher VI (P < 0.01) in medium intensive (19.3–20.9 g kg–1 LW) and low intensive treatments (17.1–18.5 g kg–1 LW) than in extensive treatment (15.1–17.9 g kg–1 LW). Higher VI (P < 0.01) was confirmed in loose housing system (15.7–20.9 g kg–1 LW) than in tie- stall housing system (15.1–19.3 g kg–1 LW). There was a negative correlation between VI and the content of fibre (P < 0.01), as well as a positive correlation between the VI and the NEL (P < 0.01).
