Disease prevention measures for terrestrial animals must be implemented as a system: control of breeding stock sources, quarantine of new arrivals, biosecurity, cleaning and disinfection, vaccination in accordance with veterinary recommendations, health monitoring, and responsible use of medication.

Controlling respiratory diseases in poultry requires shifting from a "wait-and-treat" mindset to an on-farm early warning system—monitoring respiratory sounds, feed and water intake, mortality rates, housing air quality, vaccination schedules, and daily anomalies—to enable timely intervention.

Pathogenesis, Lesion Identification, and Effective Control Protocol

CRD – a disease causing silent losses

In poultry production, CRD is one of the single biggest causes of lost profits.

The disease usually does not cause mass mortality but silently reduces weight gain, increases FCR, lowers flock uniformity, and raises medication costs.

Therefore, the flock may still look normal, but end-of-cycle profits drop significantly due to underlying CRD.
