Feeding a combination of acidogens and indigestible cation exchangers reduces manure ammonia emission rates by sequestering ammonium in the manure. Average reductions of up to 68% have been noted in production environments. Reduced levels of ammonia in the production environment improve bird and worker health, reduces bird mortality, and improves productivity.
Suitable acidogens and cation exchangers are available in the marketplace. Gypsum/zeolite blends are commercially available as a pre-mix. Implementation of gypsum/zeolite blends depends on feed bin availability, while admixing sodium bisulfate and either zeolite or humate can be done through a microbin system.
Per-ton feed costs are increased when the system is utilized, but increased feed costs are more than offset by reduced hen mortality, improved feed conversion and egg production, and reduced per-dozen production costs.
