Progress in Fermented Unconventional Feed Application in Monogastric Animal Production in China

Abstract

Unconventional animal feeds present distinct features and considerable variations. However, their efficacy in monogastric animals is hindered by high levels of anti-nutritional elements and subpar palatability. Feed fermentation could offer a solution to these issues. Moreover, fermented unconventional feeds deliver notable economic advantages and represent a viable alternative to antibiotic growth promoters, particularly in the context of antibiotic restrictions, promising considerable potential. This review provides an in-depth exploration of the types, characteristics, fermentation processes, application outcomes, associated challenges, and prospects of fermented unconventional feeds in monogastric animals. We anticipate that this comprehensive overview will serve as a valuable reference for developing and utilizing unconventional feed resources in the feed industry.
