The study was carried out with the aim to investigate the haematological and biochemical changes in broiler chickens suffering from malabsorption syndrome and tenosynovitis syndrome caused by avian reovirus. The three-day-old chicks were infected with malabsorption syndrome strain of avian reovirus. These chicks were observed for 24 days post infection. The young chickens were infected with tenosynovitis syndrome strain of avian reovirus on 46th day of age and observed for next 14 days. At the end of the observation period, blood and serum samples from infected and un-inoculated healthy chickens were examined for haemato-biogram. The haematobiochemical values of healthy chickens felt in normal range. The significant reduction in the mean values of erythrocytic count, haematocrit, MCHC, heterophils, eosinophils, total serum protein, albumin, globulin, serum iron and calcium and increase in MCV and lymphocytes were recorded in chicks infected with malabsorption syndrome strain of avian reovirus. The values of PCV, MCH, DLC, serum phosphorus, cholesterol and creatinine were non significant. The chickens infected with tenosynovitis syndrome strain of avian reovirus showed significant reduction in total leucocyte count. However, non significant decrease was recorded in total erythrocytic count, haematocrit, PCV, lymphocytes, serum proteins, iron and calcium. The values of lymphocytes, MCV, MCH and MCHC were non significantly increased. The decreased haematological and biochemical parameters in the present study indicates a decrease in the absorption and digestion of nutrients and damage to the intestines in malabsorption syndrome of broiler chicken.
