Antibiotic-free breeding means that antibiotics, hormones and other exogenous drugs are not used during the breeding process. Antibiotic-free breeding in China has been studied since 2000. Through the application of lactic acid bacteria technology, Chinese veterinary medicine technology and other technologies, antibiotic-free breeding has been achieved in a small area. In recent years, antibiotic-free feed using compound microecological preparations has been reported. It also has a certain use effect, but due to mature technology, breeding efficiency and other reasons, it has not been promoted on a large scale. Yinuotianbang Group's antibiotic-free breeding solution integrates the application of technologies such as "biological fermentation feed", "biosecurity system", "acidifier intestinal health", "micronutrient improvement" and other technologies, achieving scale The possibility of large-scale antibiotic-free breeding on the premise of “basically not modifying the farm sheds, changing the farm processes, increasing labor, or reducing efficiency” is a breakthrough, and the products currently used in pig farms Already on the market.
