The blood was collected from 15 healthy buffalo calves and 6 ‘mild’, 6 ‘moderate’ and 6 ‘severe’ ascariosis affected buffalo calves and haematological and various biochemical parameters were estimated. In haematological study involving packed cell volume (PCV), there was a significant increase in PCV in moderate and severely affected buffalo calves. In the biochemical study, parameters like calcium, triglycerides, cholesterol, globulins and albumin: globulin (A:G) ratio showed no significant difference in mild, moderate and severe ascariosis as compared to healthy buffalo calves. The blood phosphorus level of buffalo calves affected with mild and severe ascariosis was significantly increased. The Calcium:Phosphorus (Ca:P) ratio was drastically decreased in severe and mild ascariosis and moderately decreased in moderate ascariosis affected buffalo calves. The SGOT levels were significantly increased in moderate and severe ascariosis whereas the SGPT and total bilirubin levels were significantly increased in severe ascariosis. The glucose and total plasma proteins level were significantly decreased in severe ascariosis.
