ABSTRACT:
Highly concentrated aqueous L-Tryptophan and/or L-Threonine salt solutions are used to supplement mixed feeds with L-Tryptophan and/or L-Threonine. They can be metered easily and accurately, can be produced in a highly concentrated form with a content of between 30 and 70% and are storage stable to a surprisingly high degree (slight tendency to crystallize, no chemical decomposition, no racemization) even over a relatively long period of at least three months when outside temperatures are low.
