| The use of antibiotics in pig production has brought great damage and economic loss. So in the current non-resistant breeding background, the search for antibiotic substitutes in pig production has become one of the research hotspots. The article summarizes the effects of potential feed antibiotic alternatives,such as plant extracts, oligosaccharides and polysaccharides, micro-ecological preparations, Chinese herbal medicine extracts, antibacterial peptides, acidifiers, and enzyme preparations in pig production in conjunction with related research in recent years in order to provide strategies and references for formulating non-resistant diets in pig production, promoting pig production to achieve non-resistant breeding. |
