Advances in enzyme-assisted microbial fermented feed for livestock and poultry production – A review

Abstract

Microbial fermentation followed by enzymatic hydrolysis is an innovative feed preparation approach. During this process, microorganisms metabolise feed components, while enzymes catalyse the breakdown of macromolecular compounds such as proteins and cellulose into smaller, more digestible molecules. This method offers several advantages over traditional feed preparation, including increased fermentation efficiency, improved product quality, and reduced nutritional loss. These benefits can greatly enhance the production performance and overall health of animals. Recent advancements in this field have demonstrated significant potential for improving animal production performance. This article describes the various types of strains and enzymes employed in the preparation of fermented feed and its adoption in animal farming, with a focus on livestock and poultry. The study also briefly discusses the advantages, limitations, and evolution of this technology. As animal husbandry progresses towards greater intensification, scale and technological innovation, the demand for efficient and sustainable feed solutions continues to grow. This review aims to provide practical recommendations for the production and application of fermented feed in modern animal farming.
