Of the ten essential amino acids required by swine, lysine, tryptophan and threonine have been reported by many researchers as being the first three limiting amino acids in cereal based swine diets. Research reported in the 1984 Swine Field Day Proceedings suggested supplementation of threonine to an amino acid fortified, low protein, corn-sunflower meal diet improves weanling pig performance.
This trial was conducted as a continuation of the study of the effects of threonine supplementation an amino acid fortified, low protein, corn-sunflower meal diet and to estimate the dietary requirement of threonine of young growing pigs.
