Phytobiotic feed additive as a new strategy to replace synthetic antibiotics: a Review

The ban on synthetic antibiotics is the starting point for the discovery of other materials to replace them, one of which is materials of natural origin which are safer and easier to obtain is feed additive. Feed additives are additional ingredients that are mixed into animal feed to increase productivity, increase growth and improve animal health. Several feed additives that can be added to animal feed include probiotics, prebiotics, organic acids, enzymes and phytobiotics. Phytobiotic feed additives have been widely researched and developed as natural growth promoters for poultry. Phytobiotic feed additives can improve digestion and absorption of nutrients, increase enzyme secretion in the digestive tract, reduce oxidative processes, and reduce the growth of pathogenic bacteria. This mechanism has an impact on improving the health status of livestock, increasing feed intake and ration efficiency, improving carcass quality, and increasing the quality and shelf life of the meat produced. This review focused on alternatives to replace synthetic antibiotic that provide more safety to broiler production.
