The effect of productivity (high and low) and season (winter vs summer) on venous blood morphology and biochemical parameters was investigated in dairy Lacaune sheep. Thirty-two animals were included in the experiment, divided into 2 groups. It was found out that during the winter, white blood cell counts, red blood cell counts, thrombocytes, haemoglobin content, haematocrit and mean corpuscular haemoglobin increased both in high-productive and low-productive sheep (p < 0.05 – p < 0.001). Blood liver enzymes (ASAT, gamma glutamyl transferase, alkaline phosphatase) exhibited elevation during the winter (p < 0.05 – p < 0.01). No seasonal infl uence has been observed with respect to the other assayed haematological (MCH, MCV, MCHC, RDW, MPV, PDW, PCT) and blood biochemical (glucose, creatinine, total cholesterol, triglycerides, Са, Р, total protein, albumins, globulins) parameters.
