Coccidiosis continues to be one of the most economically significant intestinal diseases in broiler production. While all production systems work to prioritize bird health and responsible production, the strategies available to manage coccidiosis differ depending on whether integrators operate within No Antibiotics Ever (NAE), No Antibiotics Important to Human Medicine (NAIHM) or conventional programs. Understanding how those systems differ is critical for maintaining intestinal integrity and supporting consistent flock performance.
NAE programs do not allow antibiotics, so coccidiosis control relies on a combination of preventative and management-based strategies. Integrators commonly utilize coccidiosis vaccination programs or chemical coccidiostats alongside nutrition and gut health support. Environmental management is also especially important in NAE systems, including litter quality, moisture control, stocking density and ventilation.
NAIHM systems have additional tools available to manage coccidiosis, including ionophores and other animal-only antibiotics that are not considered medically important to human medicine. The inclusion of ionophores is one of the key differences between NAIHM and NAE production systems because ionophores help suppress coccidial replication and reduce parasite loading within the house. This often results in more controlled coccidial cycling and more predictable flock performance over time.
Conventional production systems provide the broadest range of approved tools for managing coccidiosis and intestinal health. These systems may utilize ionophores, chemical coccidiostats and antibiotics important to human medicine when appropriate for disease prevention or treatment.
Regardless of the system, intestinal integrity remains essential because disruption of the gut barrier can create opportunities for secondary bacterial infections and performance losses. During peak challenge periods, integrators often focus on tightening management practices, monitoring litter moisture and ventilation more closely and making nutritional adjustments to help support gut health.
Long-term success in any production system depends on proactively managing coccidiosis, protecting intestinal integrity and utilizing available tools strategically. Elanco Poultry Technical Consultant can help integrators evaluate their intestinal health challenges and identify management and program strategies that best fit their production system.
