Abstract
The aim of this study was to determine the chemical composition and nutritional value of the dominant species and subspecies of the grassland community Scorzoneretalia villosae. The research was carried out on the grasslands of the Ćićarija plateau. In the collected samples of 17 dominant plants, the content of the dry matter (DM), crude protein
(CP), ash, neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), in vitro digestibility of DM (IVDMD) and net energy for lactation (NEL) were determined. According to the spring content of CP and IVDMD, Hippocrepis comosa (CP 181 g/kg DM, IVDMD 63.5%), Scorzonera villosa (CP 121 g/kg DM, IVDMD 61.5%) and Satureja montana ssp. variegata (CP 83 g/kg DM, IVDMD 60.4%) were the most nutritious and very palatable for sheep while the most unfavorable chemical composition had Stipa pennata ssp. eriocaulis (NDF 790, ADF 396 and ADL 112 g/kg DM) and Brachypodium pinnatum ssp. rupestre (NDF 789, ADF 483 and ADL 86 g/kg DM). A high IVDMD was determined for Salvia pratensis (up to 70.6%) and Teucrium chamaedrys (67.1%), generally hepatotoxic species, but not toxic for the local
herd. In this paper, nutrition indicators of collected species and subspecies are presented for the first time.
