Three-year studies were conducted in the area of the Centre of Forest Environment Studies and Chase Game Breeding of Agricultural University of Wrocław. The subject of the investigation was the alimentary base for the deer family in the existing and newly established green crops in this area. The crop yield, botanical composition and alimentary value of the ground flora were determined. The hematological and biochemical indexes were determined in blood and serum of roe deer, deer and fallow deer during a hunting season within deer-hunting periods. Besides, pH, N-NH3 and LKT sum were determined in rumen content samples taken from the animals shot during hunting. The alimentary value of fodder coming from green crops depended on the brand composition of ground flora, particularly with regard to protein; fibre and its fractions (ADF, NDF). The level of protein-energy metabolism metabolites in the animals’ rumen depended on the species. The hematological and biochemical indexes of blood and blood serum were considerably diversified depending on the species and showed great divergence within species.
