In an interview with Poultry Producer, Dr. Arango discusses the economic impact of Necrotic Enteritis (NE) and coccidiosis and outlines practical strategies to help reduce risk. Both diseases remain significant threats to flock performance and profitability, requiring proactive and coordinated management.
The economic burden is substantial. NE is estimated to cost the global poultry industry approximately $6 billion annually, according to a 2025 analysis. Coccidiosis, however, represents an even greater challenge, with recent global loss estimates exceeding $14 billion per year – making it the most costly poultry disease worldwide. Beyond its direct impact, coccidiosis is also a key predisposing factor for NE. Intestinal damage caused by Eimeria species creates favorable conditions for Clostridium perfringens overgrowth, increasing the likelihood and severity of NE. Effective coccidiosis control can therefore play a critical role in reducing overall NE risk.
Understanding susceptibility is equally important. There are no standardized routine monitoring systems specific to NE, so careful observation is essential. Spikes in mortality and the presence of intestinal lesions during necropsy are important warning signs. Eimeria maxima is particularly significant because it damages the intestinal lining, disrupts nutrient absorption and contributes to the intestinal environment that allows NE to develop. Nutrition and litter conditions also influence risk. Poor digestibility, excess undigested nutrients and wet litter can all increase pathogen pressure and intestinal stress.
Preventing NE requires integrated management. Biosecurity, coccidiosis control, nutritional optimization, feed additives and strong litter management must work together to reduce overall challenge pressure. As environmental conditions shift throughout the year, adjustments to ventilation, litter moisture control and program timing can help minimize risk.
Proactive coordination with a poultry veterinarian and technical teams remains essential to establish, monitor and refine effective prevention programs.
