Cryptosporidiosis is a rare but potential intestinal infection causing diarrhoea in Angora goat kids. Cases of diarrhoea and death have been recorded in Angora goats in Australia. ( Aust Vet J. 1981 Aug;57(8):386-8. Intestinal cryptosporidiosis in a kid goat. Mason RW, Hartley WJ)

Cryptosporidium is a cause of diarrhoea in calves in South Africa.

What age of kids are affected?

Infection usually occur in kids 1-4 weeks old

How can Angora kids be infected?

The infection is via contaminated food or water. Cryptosporidiosis is also often associated with other intestinal infections such as E.coli. Stress is important in the development of the disease.

The oocytes shed in the faeces are very resistant in the environment. Clinical signs can occur 2-7 days after infection and may last 1-2 weeks. Death rates are low.

Clinical signs:

  • Except when occurring in very young kids the infection is in apparent or causes a mild diarrhoea.
  • A profuse yellow diarrhoea can occur. Kids will be anorexic and depressed.
  • Loss of body weight

Post Mortem:

  • Intestine contains yellow water fluid
  • Lesions are found in the ileum, caecum and colon.
  • Hyperaemic intestines

Control and Control

There is no effective treatment. Supportive therapy.

Paromomycin sulfate (100 mg/kg/day, PO, for 11 days from the second day of age) proved successful in preventing natural disease in a controlled clinical field trial in goat kids.

  • Fluids: oral and parental.
  • Raise kids in clean and dry environment, clean ‘lamhokke’
  • Isolate kids with diarrhoea
