How to reduce the addition of AGP antibiotics in animal feed is an important issue in the animal husbandry industry for now and the future. DaChan Group has been optimizing and upgrading the animal feeding and management system for years, and also focuses on the research and development of feed additives that are able to substitute antibiotics, including probiotics and their fermented products. Through the unique strain screening platform of Total Nutrition Technologies Co., Ltd., lactic acid bacteria strains that can effectively promote animal health and growth are finally selected and used to develop live bacteria and functional feed materials products which are widely used in poultry, livestock and aquaculture. Even more, the lactic acid bacteria product has even been successfully applied in commercial-scale antibiotic-free broiler chicken husbandry, which opens a new page for the sustainable development of Taiwan's livestock industry.
