ABSTRACT

Thirty and seven hares catched in late Autumn and Winter were examined for the composition of digesta and for characteristics of femur bone. The very great variability among individuals was observed in analysed parameters. The average pH values of stomach content reached 3.4, in duodenum and in small intestine reached 6.4 and 6.3, respectively. Concentration of
crude protein varied at range from 2.2 to about 7.7% and the crude fibre in content of stomach amounted to 24% in DM basis, in duodenum (2.6% in DM) and in subsequent small intestine parts. Concentration of K, Cu and Zn gradually decreased during the passage of digesta through the intestine. The calcium content clearly increased along the gastrointestinal tract. The average crude ash content in femur bones was relatively high and amounted 43%. Conducted investigations confirms the substantial technical problems in estimation of nutritional statements and/or its tendencies in hare' organism.

Key words: hare, composition of digesta, femur bone.
