A study on alteration in clinico-haematological parameters in colibacillosis affected diarrhoeic cattle calves

Abstract

The objective of the present study was to evaluate clinico-haematological changes occurred in colibacillosis affected diarrhoeic calves below one month of age. The study was undertaken in cattle calves at private dairy farms as well as animals of individual holdings in Bikaner district of Rajasthan. A total number of 32 diarrhoeic calves (Escherichia coli positive) and eight clinically normal healthy calves (as control) were taken to investigate the clinico-haematological profiles. E. coli was isolated from the diarrhoeic calves and the animals found positive on the basis of multiplex polymerase chain reaction, were used for the study. Analysis of clinical profile and blood samples of the diarrhoeic calves revealed significant increase in haemoglobin, PCV, TEC, MCV, MCH, TLC and neutrophills while significant decrease in lymphocytes were recorded. However, no significant changes were observed in MCHC, eosinophils, basophils, rectal temperature, respiration rate and heart rate.
