Abstrakt: An epidemiological study was conducted for detection of rotavirus by antigen ELISA kit in dairy calves from Central India (Madhya Pradesh and Chhattisgarh states) and North India (Uttar Pradesh state). Different epidemiological parameters like age, sex, parity, colour and consistency of faecal materials and seasonal changes in a year were recorded. A total of 816 faecal samples were screened and out of which 41 (5.02%) animals were found to be positive for rotavirus A. The higher prevalence was recorded in North India followed by Central India. Age-wise higher prevalence was recorded in calves under 1 month of age. Significantly (p < 0.05) high prevalence was noticed in male calves compared to female calves. Seasonally, the prevalence of RVA infection was significantly higher (p < 0.05) in winter season and in first parity of calves as compared to other season and parity. Prevalence of Rotavirus infection was higher in pasty yellow colour faecal materials than watery diarrhoea. The observations of the present study would provide the basis for further an effective explorative surveillance and epidemiological studies to know the real impact of rotavirus infection with associated risk factors in dairy calves of India.
