Dr. R Shirisha, Dr. Umesh BU and Dr. K Prashanth
The global poultry industry is facing severe economic pressure due to high prices of feed ingredients. High soya prices make alternative ingredients more attractive. However, their availability is limited. When partially replacing soya bean meal, DGGS and rape seed meal, both by-products of the biofuel industry are of particular interest. However, their protein digestibility is lower compared to soya and can be more variable. Therefore, all formulations with alternative ingredients must be based on digestible amino acids. Amino acids (AA) are important in poultry nutrition not only for protein deposition, but also for other metabolic functions; such as improving immune and gut function. Recent advances have been made in developing industrial process for economical production of synthetic amino acids. L-Lysine, DL-Methionine, L-Threonine and L-Tryptophan, L-Valine in commercial poultry birds to reduce the feed cost. This has resulted in poultry Nutritionists reducing the crude protein levels while maintaining the bird performance and profitability. This review examines broiler literature on L-Threonine and makes extrapolations relating to commercial conditions. Further functions of L-Threonine in metabolism and threonine content of feedstuffs are discussed.
