Performance of Broilers Fed with Maize Colonized by Either Toxigenic or Atoxigenic Strains of <em>Aspergillus flavus</em> with and without an Aflatoxin-Sequestering Agent
In warm agricultural areas across the globe, maize, groundnut, and other crops become frequently contaminated with aflatoxins produced primarily by the fungus <i>Aspergillus flavus</i>. Crop contamination with those highly toxic and carcinogenic compounds impacts both human and animal he...

In warm agricultural areas across the globe, maize, groundnut, and other crops become frequently contaminated with aflatoxins produced primarily by the fungus <i>Aspergillus flavus</i>. Crop contamination with those highly toxic and carcinogenic compounds impacts both human and animal health, as well as the income of farmers and trade. In Nigeria, poultry productivity is hindered by high prevalence of aflatoxins in feeds. A practical solution to decrease crop aflatoxin content is to use aflatoxin biocontrol products based on non-toxin-producing strains of <i>A. flavus</i>. The biocontrol product Aflasafe<sup>®</sup> was registered in 2014 for use in maize and groundnut grown in Nigeria. Its use allows the production of aflatoxin-safe maize and groundnut. A portion of the maize treated with Aflasafe in Nigeria is being used to manufacture feeds used by the poultry industry, and productivity is improving.
