ABSTRACT
Among the multiple causes, diarrhoea in neonatal calves is one of the most challenging clinical syndromes encountered by large animal veterinary practitioners due to multiple etiologies and its severity. Moreover, the preexisting factors and the intricacy of calf diarrhoea due to bacterial pathogens like E. coli, enforced to conduct research work on some important clinical aspects of the disease with the objectives to study haematological and haemochemistry alterations in positive cases of collibacillosis. Isolation and then identification of bacterial pathogens and confirmation of E. coli strains associated with calf diarrhoea along with their clinical examination of common clinical parameters such as rectal temperature, pulse rate and respiratory rate revealed non-significant difference in body temperature; and significant difference in pulse rate and respiration rate in diarrheic calves in comparison to apparently healthy calves. When haematological parameters were compared, there was a significant increase in parameters like packed cell volume and Total Leukocyte counts which was suggestive of dehydration. The increased number of neutrophils and leukocytosis in early stage of diarrhoea clearly indicated involvement of bacteria. Biochemical profile revealed significant increase in chloride level in diarrheic calves as compared to apparently healthy calves and suggested the presence of hyperchloremia in diarrheic calves
