Nutrient concentration in consumed dry matter is the most actual problem of animal nutrition in the Czech Republic. Seven sequential samplings of 8 grass varieties (2 hybrids of Lolium multiflorum x Festuca arundinacea, Lolium perenne, 2 varieties of Lolium perenne, Festuca pratensis, Festuca arundinacea, Dactylis glomerata, Bromus uniloides) in weekly intervals during the 1st cutting period and samplings during the 2nd cutting period were realized in 1999 on two localities. Milk production was calculated from the energetic value of forage (NEL) during the vegetation period and expressed by means of kg FCM produced by a dairy cow consuming 13 kg of dry matter and requiring 3.13 MJ NEL per kg. The decrease of nutrient and energy concentrations in forage is associated with a lower productive efficiency of roughage. It is necessary to harvest grasses from May 20 to May 25 (1st cutting); the 2nd cutting should be realized until 45 days after the 1st cutting.
