Additives are not the only area that require attention when antibiotics are removed from feeds.
The use of antimicrobial compounds at growth-promoting levels was first banned in Sweden 30 years ago, and it is now reaching global levels with many countries joining. Following the ban, the use of antibiotics for therapeutic purposes increased dramatically, but overall use was markedly reduced. Lamentably, animal productivity was also reduced, and as such alternatives were sought to replace antibiotics. To the dismay of most animal producers, no single product has been identified as able to fully replace banned antibiotics.
