The challenges of coccidiosis in poultry

Coccidiosis is a constant and costly threat to the poultry industry, shown to significantly and negatively impact broiler chicken production.

Cocci hex 1

> Different parasite species = peaks at different bird ages

> Late outbreaks can occur due to poor immunity

Cocci hex 2

> A ubiquitous parasite

> Can survive in the environment for long periods2

coccidiosis negatively impacts key performance indicators

> Broiler feed conversion rate (FCR): up to 10%3

> Weight gain: up to 7%3

> Intestinal Integrity (I2) scores4

> Mortality5

> Disease rates6-9

Don’t let coccidiosis negatively impact your broiler flock


Monitoring bird Intestinal Integrity (I2) scores via HTSi makes sure that coccidiosis in
birds is not quietly impacting the productivity of a flock over time.
