Studies on haemato-biochemical changes in calves due to Toxocara vitulorum Infection

Abstract

A study was carried out in both local and cross-bred cattle calves of Assam upto 6 months of age suffering from Toxocara vitulorum infection to estimate the haemato-biochemical changes. Blood samples were collected before treatment and after treatment to analyse the status of Haemoglobin, Packed Cell Volume (PCV), Differential Leukocytic Count (DLC), Total Leukocytic Count (TLC), Total Erythrocytic Count (TEC) and biochemical status such as Total serum Protein and Blood glucose. The pre-treatment values of Hb(g/dl), PCV (%) amd TEC in all the infected groups were significantly lower than the healthy control group whereas, the value of TLC were significantly higher. The biochemical values of Total Serum protein and Blood glucose was found to be significantly lower in infected calves. However, the haemato-biochemical values gradually returned to normal after 7th day onwards post-treatment.
