Suitability of litter amendments for the Australian chicken meat industry

A normal process of feed digestion in chickens includes the excretion of nitrogen in their manure. If the system is not managed appropriately, high levels of ammonia can form and can be detrimental to chicken health and welfare. Internationally, ‘litter amendments’ are products used to decrease ammonia formation in the litter, however, there is varied information on which amendments may be effective, to what extent, and in which situations.

The aim of this project was to undertake a detailed review of information available on litter amendments, accompanied by an industry survey to provide the Australian chicken meat industry with a detailed, impartial assessment of the potential benefits of amendment use, along with guidelines for its effective implementation.

For farms that reuse litter or are considering reusing litter, a fact sheet is available that explains the benefits and challenges of using litter amendments, how different types of amendments work and other strategies to control ammonia.
