Canadian producer reaps benefits of coccidiosis vaccination — all year long

Then, when winter arrives, switch back to the medication program for three more cycles and continue with that rotation.

Field experience shows perils of late coccidiosis challenge

Real-world experience is corroborating research indicating that a coccidiosis challenge late during the production cycle takes a far more serious toll on broilers and the producer’s wallet than an early coccidiosis challenge.

Late coccidiosis challenge has ‘profound’ impact on profits

A coccidiosis challenge late in the production cycle has a profound, negative effect on energy utilization, flock performance and profitability — even when coccidial gut lesions are minor, indicates expansive research by a US nutritionist.
