Thirty-two Polwarth sheep of ages up to 1 year were observed under temperatures varying from 10.5 to 46.5 degrees C. The following blood cell counts were made: erythrocyte (RBC), leucocyte (WBC), eosinophil (EOS), neutrophil (NEU), lymphocyte (LYM) and monocyte (MON). Other traits measured were: haemoglobin (HB), haematocrit (HT), blood glucose (GLU) and serum protein (PROT). Multivariate analysis of variance was used and the results showed a significant (P < 0.001) effect for the interaction of shearing and temperature treatment. Under temperatures > 25 degrees C, sheep presented a decrease of RBC, WBC, HB and HT, these differences being greater in the shorn than in the unshorn animals. Unshorn animals presented higher variations in EOS, NEU, LYM, MON and GLU. Blood glucose increased under high temperatures in the shorn animals (from 56.36 +/- 0.65 mg/100 ml to 60.52 +/- 0.69 mg/100 ml) as in the unshorn animals (from 54.72 +/- 0.74 mg/100 ml to 57.56 +/- 0.77 mg/100 ml).
