Coccidiosis can occur wherever cattle are raised and is highly infectious. The most well-known sign of coccidiosis is bloody diarrhoea. However, up to 95% of infected calves show no sign of this but are still affected by this disease.

Symptoms of coccidiosis can include:

  • Loss of appetite
  • Reduced feed intake
  • Retarded growth
  • Dehydration
  • Secondary infections
  • Watery diarrhoea accompanied by mucus, straining and blood

Symptoms are often subtle and easily overlooked. However, damage caused to the gut surface means there is a lower feed conversion rate. This and a reduced appetite lead to retarded growth, preventing calves from reaching their full potential.
