Cryptosporidiosis (Crypto) is a leading cause of severe calf scours, particularly in calves less than one month old. Infection commonly results in diarrhoea, dullness, and poor growth.
Once established, Crypto is very difficult to eliminate from calf-rearing areas. The parasite spreads easily, survives for long periods in the environment, and is resistant to many disinfectants.
Even with good hygiene and management, calves can be exposed in the first few days of life—making prevention and early protection critical in any effective calf health programme.
Why Early Protection Matters
Calves are most vulnerable to Crypto from birth, when their immune system is still developing.
Early infection can lead to:
Concurrent infections with E. coli, rotavirus, and coronavirus are also common, making disease more severe and harder to manage.
Because treatment options are limited, the focus must be on:
