Abstract

Brazil is the largest producer and exporter of beef in the world, being considered the largest commercial herd. Diarrhea is considered to be the main illness that affects neonates causing losses in early development. The interactions between nutritional management, environment and infectious microorganisms result in neonatal diarrhea in calves, causing welfare problems and economic losses due to mortality and treatment costs, growth retardation. Neonates are susceptible to infections and need management attention. Aiming at the prophylaxis of pathologies in the herd, it is essential to be accompanied by an employee oriented and prepared to carry out interventions if necessary. The main pathogens related to this disease are Salmonella sps, Escherichia coli, Cryptosporidium parvum, Rotavirus, Coronavirus. The treatment of this condition is based on isolation, rehydration with electrolyte solution and intravenous infusion if the calf is unable to feed itself, antimicrobial therapy can also be instituted. Thus, a new reading on the main types of bovine neonatal diarrhea is necessary, aiming at diagnosis, treatment and prevention of the property, in order to reduce expenses on it.
