Abstract The analysis of haematological parameters is an important element of the assessment of the physiological condition of animals. Haematological parameters may change both under the influence of various external factors, and in the course of normal pregnancy, which has been found in various species of mammals, including rabbits. Our study showed statistically significant (p 0.05) changes in basic haematological parameters: RBC (decrease; 5.87±0.48 at day 15 vs. 5.42±0.32 T/L at day 26), MCH (increase; 1.35±0.04 before matching vs. 1.41±0.03 fmol at day 26), RDW (decrease; 15.77±1.80 at day 15 vs. 14.27±1.57% at day 26) MPV (increase; 5.17±0.31 at day 15 vs. 5.92±0.70 fL at day 26), WBC (decrease; 8.60±2.57 at day 15 vs. 4.94±0.88 G/L at day 26) and PLT (decrease; 398.17±91.67 before matching vs. 271.67±61.72 G/L at day 26) in Termond White rabbits and RBC (decrease; 6.18±0.68 before matching vs. 5.68±0.54 T/L at day 26), Hb (decrease; 8.00±0.90 before matching vs. 7.32±0.71 mmol/L at day 26), MCH (decrease; 1.32±0.05 at day 15 vs. 1.29±0.04 fmol at day 26) and WBC (decrease; 9.62±1.81 before matching vs. 5.85±2.23 G/L at day 26 as well as 9.58±2.35 at day 15 vs. 5.85±2.23 G/L at day 26) in Popielno White rabbits. Moreover, in the Popielno White rabbits we recorded a significant (p 0.05) decrease in the percentage of irregular erythrocytes at the end of pregnancy (11.00±10.02 at day 15 vs. 3.00±4.94 at day 26). The changes appear to be physiological but should be considered in studies using rabbits as model organisms.
