- The influence of threonine has been studied in broilers; however, information concerning the phase from 1 to 7 d is lacking. In this study, we evaluated the effects on performance and body composition and the relationship with other amino acids with respect to digestible lysine and total glycine + glycine. Research on the initial 7-d phase of broiler growth is still poorly studied, even though it is important, especially in nutrition. It was found that threonine had a great influence on the broilers at that phase and nutritional recommendations need constant evaluation. In conclusion, the digestible threonine: digestible lysine ratio and digestible threonine: total glycine + serine ratio recommended for better performance and body composition are 0.68 and 0.40, respectively. The levels of digestible threonine and total glycine + serine that provide the best results are 0.864 and 2.192%, respectively.
