Diarrhoea is a major cause of death in calves and other young ruminants. This form of neonatal gastroenteritis is caused by ingested microorganisms that reach the gut. Many different microorganisms can cause neonatal diarrhoea, including viruses (Rotavirus, Coronavirus), bacteria (Salmonella, enterotoxinogenic E.coli K99) and protozoa (Cryptosporidium parvum, coccidia). Viral infection often paves the way for bacterial superinfection which exacerbates the problem and prejudices the outcome. The first consequences of diarrhoea are loss of appetite, abdominal retraction and tightness, and lethargy. In animals, diarrhoea can quickly lead to dehydration followed by paralysis, circulatory failure and death. Diagnosing the cause of the diarrhoea will necessarily involve laboratory testing because the causative agent cannot be identified on the basis of the symptoms alone. The best prophylaxis against neonatal diarrhoea is to ensure that the neonate is given an adequate dose of colostrum as soon as possible after delivery.
