Ammonia Control

Ammonia Control 250 (AC250) is a liquid concentrate additive that is approved to be added to swine, broiler and pullet feed rations to reduce the level of ammonia in the barn system for only a fraction of the cost of feed.

AC250 claims are supported by approval from the Canadian Food Inspection Agency (CFIA) on reduction of ammonia throughout the barn system.

The Truth About Ammonia in Swine

Elevated concentrations of harmful gases, such as ammonia, are associated with several production factors including: reduction in average daily gain, increased number of days to market, as well as higher mortality rates and medication costs.

  • Ammonia can reduce performance and increase the incidence of disease
  • The typical range of ammonia in hog barns is 5 to 50 ppm, with numbers often in excess of the 25 ppm recommended threshold level
  • Concentrations at the level of 50 ppm ammonia can cause significant reductions in average daily gain
  • The concentration of ammonia can be as much as 60% higher at the animal breathing zone than at the human breathing zone.

Ammonia in Poultry

  • Based on a 2013 study done by MTS Environmental Inc. with 8 pairs of broiler barns, using Ammonia Control 250 reduced ammonia levels in the treated barns by 41%
    • untreated barns averaged 28.4 ppm, with a range of 16 to 69 ppm
  • “Elevated levels of ammonia can have a negative impact on animal health and production. For example, reduced final body weights have been observed in poultry produced in houses with indoor ammonia levels of approximately 25 [ppm] or higher during brooding.” (reference: Reece et al, 1980 cited in Gay S.W. & Knowlton K.F. 2009.)

Ammonia can also have a negative impact on human health; exposure to ammonia can irritate the respiratory tract and eyes, even at low levels.
