[Influence of thermal and mechanical treatment of animal feed on the true digestibility of amino acids. 1. True digestibility of amino acids in soy bean meals treated by varying heat].

Thermal treatment inactivates harmful components in some feedingstuffs such as extracted soy bean meal. The true digestibility of amino acids from untreated and heat-treated extracted soya bean meal had been determined in order to investigate the great variety of ways in which thermal treatment might affect food proteins, e.g. in producing a decomposition of inhibitors or damaging the amino acids. The trials were carried out with young pigs.
