This report reviews the amino acid tryptophan which is an essential amino acid in the diet of Australian poultry. Reliable values of total and digestible tryptophan in feedstuffs are needed because tryptophan is often the third most limiting amino acid in poultry diets. Understanding the inclusion of tryptophan in poultry diets will also facilitate the strategic use of commercially available synthetic, feed-grade tryptophan in the Australian poultry industry.
