Abstract

The purpose of the study was to identify the prevalence of diarrhea caused by rotavirus and coronavirus in newborn calves located in the North-West region of the republic using rapid testing. The study was conducted among 45 heads of calves of local races and crosses in 20 farms of the Ismailli, Gabala, and Zagatala districts. In 14 heads of calves out of 45 calves (35.5%), pathogens were not identified, and in 31 heads of calves pathogens were identified in single or mixed cases. The identified pathogens among them were distributed as follows: rotavirus in 22 calves (48.9%), coronavirus in 3 calves (6.7%), in 8 calves - (cryptosporodium parvum) 17.8%), in 5 calves calves - Giardia (11.1%) and another 5 calves had E. coli K99 (11.1%). The results of the study show that the causes of diarrhea in calves in the North-West region of the republic, among other pathogens, include rotavirus and coronavirus infections, and it is important that this be taken into account when carrying out treatment and preventive measures.
