Investigations on the nutritional value of green fodder and hay originated from ecological meadows were carried out in 2006-2008 in some ecological farms with ecological certificates and those which were in their second year of transfer from ordinary to ecological farms. The following parameters were assessed in the pooled samples which were analysed in the Laboratory of the Department of Animal Feeding and Food Management of Poznan University of Life Sciences: yield, moisture content, content of beta-carotene, ash, fibre and crude fat as well as reducing sugars, gross energy and fibre fractions for ADF and NDF content. The quality of the analysed roughages was characterised by moderate nutritional value. This could be attributed, primarily, to late cutting (after the first of July) due to the realisation of nature packages. The content of crude protein in the green fodder and hay was relatively low and amounted, on average, to 6.22 percent and 11.28 percent in DM and the content of crude fibre, to 10.14 and 28.62 percent in DM, respectively. The obtained forages constituted a valuable fodder base and a source of income
