Threonine could replace growth promoters
Adding amino acids like threonine and lysine completely compensates the lack of growth promoters in pig feed.
Studies by the Dutch institute Schothorst Feed Research support this conclusion. The institute discovered that pigs predominantly need more threonines when not being fed growth promoters.
When the animals are still being fed growth promoters, however, adding lysine or threonine does not appear to work.
Pigs having a threonine-lysine percentage of about 65 to 70% in the feed perform as well as when being fed meals containing growth promoters.
