Abstract

Bovine neonatal diarrhoea (BND) is a problem of great relevance in cattle herds, resulting in a decline in productivity and performance in production units, and causing great economic losses. The objective of the study was to determine the prevalence of BND in the state of Veracruz. In total, 300 lactating calves were sampled. Samples were analysed for Rotavirus, Coronavirus, Escherichia coli and Cryptosporidium spp. Differences between groups were determined by chi-square and risk factors were determined by Odds Ratio. The general prevalence of three geographical areas sampled was 85%. Regarding the analysed pathogens, Cryptosporidium spp. Had the highest prevalence with 76%, followed by E. coli with a prevalence of 42%. Two pathogens were present in coinfections with a 32% prevalence, unlike diarrhoea caused by one, three or four pathogens. Calves that consume standing water after birth present a higher risk of infection. It is necessary to establish sanitary
programmes to reduce the risk of infection, help to avoid economic losses, and improve the productivity of the herd. BND related pathogens Rotavirus, Coronavirus, Escherichia coli and Cryptosporidium spp. are present in the sampled areas.
