Reducing imported soybean in swine and poultry feeds – a new role for feed-grade amino acids

Supplemental feed-grade amino acids (FG-AA) have been used in the diets of non-ruminant animals for over five decades.  Although early adoption was based on least-cost formulation, there has been interest of late in lowering CP content of feeds with higher supplementation levels of FG-AAs. Recent studies have shown that the use of FG-AA can lower nutrient input into the system and reduce environmental emissions, without compromising productivity.

Ermias presents the latest knowledge in…

  • Reducing our soybean dependency – how supplemental FG-AA can reduce the need for soybean meal by 50%
  • Improving the environment – how greenhouse gases can be reduced through changes in land use and other environmental benefits
  • The way forward – how FG-AA can be safely adopted by the feed industry
