A new type of high-efficiency feed additive, micropolyprotein, was recently successfully developed by the Institute of Bioengineering, Nanjing University of Science and Technology. The school’s pilot plant has produced qualified products. The product is a chelate produced by coordination complexation with metal ions under certain reaction conditions, which is a non-plant protein biuret as a ligand, and can substitute part of plant proteins to feed ruminants, and has a significant reduction. Feeding costs and increasing economic benefits. The product fills the blank both at home and abroad and has been listed by the National Science and Technology Commission as a “Guideline for National Key Scientific and Technological Achievements Promotion Programâ€. At present, China has established production bases in Jiangsu Jiangyan and Shanxi Jin'an through technology transfer or technology incorporation. The cumulative output is about 3,000 tons, and it is located in Jiangsu, Shanxi, Hebei, Henan, Inner Mongolia and Heilongjiang. More than a dozen provinces, municipalities and autonomous regions to promote the application.
