Blood parasite disease in chickens is undoubtedly an frequently underdiagnosed but sizeable threat to poultry wellness and productiveness, specially in tropical and subtropical locations. Caused by microscopic protozoan parasites that invade the bloodstream, these infections can cause Long-term health concerns, financial losses, and, in critical conditions, high mortality rates in flocks.

Doing away with standing h2o to reduce insect breeding
Utilizing mosquito nets or screens in poultry housing
Applying Secure insecticides or repellents
Employing biosecurity measures and quarantining new birds
Normal wellness monitoring and early veterinary intervention
Elevating awareness among poultry farmers and providing access to veterinary services can go a good distance in blocking outbreaks.
