The chemical composition and in vitro dry matter digestibility of 45 samples of different species of lichen are reported. Mean content (g/100 g dry matter) of the main nutrients was: crude protein 4.2, crude fat 3.2, crude fibre 16.6, ash 1.9, Ca 0.15, P 0.09, Mg 0.05, K 0.13, Na 0.035, S 0.07. The content of microminerals (mg/kg dry matter) was; Cu 2.5, Mo 0.11, Zn 27.2, Se 0.12, Fe 898, Mn 154. The mean in vitro dry matter digestibility was 35 %. However, the in vitro method do underestimate the dry matter digestibility of lichens. Stereocaulon spp. showed higher levels of crude protein, P, S, Cu and Mo than Cetraria spp. and Cladonia spp. Cetraria nivalis showed higher digestibility and contained more NFE, ash, Ca, Mg, but less crude fibre than Cladonia stellaris. Lichens contained less amounts of most nutrients compared with grasses (Figure 1), exept for crude fat, NFE, Se and Fe
