Monitoring for Success

Monitoring your flock by assessing average daily gain, feed conversion, water intake and the number of flocks with coccidiosis diagnosed is a good first step to measure overall flock health.

There are two specific coccidiosis monitoring methods: lesion scoring and oocyst counting. Usually, lesion scoring is used when the prevention method is anticoccidial drugs while oocyst counting is used when the prevention method is live vaccine. However, these two monitoring methods can also be used at the same time with a flock given any coccidiosis prevention method (please consult your veterinarian).

The monitoring methods can be suggested by the veterinarian, feed or vaccine technical representative. Regardless, post-mortem analysis by a veterinarian should always be performed whenever a flock experiences higher signs of disease or mortality.

The presence of lesions always comes before oocyst shed in the environment. Lesions are formed due to the asexual and sexual cycle of the parasite, whereas oocyst formation and shed occurs after these stages. See the Parasite Biology: Life Cycle section for more information.
