Toxin Binders: A Key Strategy in Modern Poultry Farming, Says Expert Adeleye Ajao

Aflatoxins, particularly Aflatoxin B1 (AFB1), present a significant threat to poultry health and productivity. These toxic metabolites, produced by certain Aspergillus fungi, contaminate feedstuffs and can lead to reduced growth rates, immune suppression, and increased mortality in poultry.

Dr. Adeleye Ajao, a leading expert in poultry science and animal nutrition, emphasises the crucial role of toxin binders in mitigating these adverse effects.

“Toxin binders have become an indispensable tool in modern poultry production,” states Dr. Ajao. “They work by adsorbing and sequestering mycotoxins like AFB1 in the bird’s gastrointestinal tract, effectively reducing the bioavailability of these harmful substances.”

This process, he explains, prevents the toxins from being absorbed into the bloodstream and distributed to various organs, thus protecting the bird’s overall health.

The mechanism of action of toxin binders is multifaceted. “Primarily, these binders adsorb AFB1 molecules onto their surface, forming a stable complex that is then excreted,” Dr. Ajao clarifies. “Some binders also interact chemically with AFB1, neutralising its toxic effects, while others can enhance the metabolic degradation of AFB1 into less harmful metabolites.”

Dr. Ajao highlights the variety of toxin binders available to poultry producers. “Clay-based binders such as bentonite, montmorillonite, kaolin, and zeolite are commonly used,” he notes. “Bentonite and montmorillonite are particularly effective due to their high absorption capacity.”

Activated charcoal, with its porous structure, is another potent adsorbent. Synthetic polymers like polyvinylpolypyrrolidone (PVPP) and organic binders such as yeast cell wall extracts, rich in mannan oligosaccharides and beta-glucans, also play a vital role. Furthermore, some enzymes can degrade AFB1, although they are often used in conjunction with other binders for maximum efficacy.

The benefits of using toxin binders are substantial, according to Dr. Ajao. “Improved growth performance is a key outcome,” he asserts. “By reducing AFB1’s bioavailability, these binders help maintain normal growth rates and feed conversion ratios.” Moreover, toxin binders enhance immune function, which is often compromised by AFB1. “This leads to healthier, more resilient poultry, less susceptible to infections,” Dr. Ajao adds.

Lower mortality rates and better feed efficiency are additional advantages. “Effective binding of AFB1 reduces the incidence of aflatoxicosis, resulting in lower mortality,” Dr. Ajao explains. “Additionally, toxin binders improve nutrient absorption and utilisation, maximising feed efficiency.”

Dr. Ajao emphasises the importance of proper application. “Dosage and inclusion rates must be carefully considered, varying based on the type of binder and the level of AFB1 contamination,” he advises. “Following manufacturer recommendations and regular feed testing are crucial.”

He also advocates for a holistic approach. “While toxin binders are effective, they should be part of an integrated mycotoxin management strategy that includes proper feed storage, regular testing, and the use of high-quality feed ingredients.”

Continuous monitoring and adjustment are also essential. “Regular monitoring of feed and poultry health allows for timely adjustments in the use of toxin binders, ensuring optimal protection against AFB1,” Dr. Ajao states.

Dr. Ajao’s expertise in poultry science is underscored by his extensive academic and professional background. He holds a Ph.D. in Monogastric Animal Nutrition from the Federal University of Agriculture Abeokuta, Nigeria. His experience includes a Research Assistant at FUNAAB, where he led numerous research projects and mentored students.

In addition to his research and consultancy work, Dr. Ajao has held significant operational roles, including Chief Operating Officer at Birdpreneur Farms Limited, where he successfully managed day-to-day operations and implemented strategies to increase revenue and reduce costs. His commitment to advancing agricultural practices is further demonstrated by his teaching experience at the Federal University of Agriculture Abeokuta and his involvement in various leadership and volunteer activities.

Dr. Ajao’s contributions to the field have been recognised with numerous awards, including the recognition for his innovative agribusiness initiatives. He is also an active member of several professional organisations, such as the Poultry Science Association and the World Poultry Science Association.

“Toxin binders are indispensable for maintaining poultry health and productivity in the face of Aflatoxin B1 contamination,” Dr. Ajao concludes. “Their effective use, combined with other sound management practices, is essential for ensuring the safety and profitability of poultry operations.” His ongoing research and expertise continue to contribute significantly to the advancement of poultry science and the well-being of the industry.
