Scope

Scope: This guideline stipulates the general design requirements for the production technology of biological organic trace elements, the screening and evaluation of fermentation strains, fermentation processes and parameters, product quality control, and addition ratios, etc. This guideline applies to the use of microbial fermentation to produce organic trace elements approved by the Ministry of Agriculture of the People's Republic of China in Announcement No. 2045, "Feed Additive Variety Catalog (2013)", and can be used as a technical basis for the design of biological organic trace element production schemes, fermentation processes, quality control, and product testing. 3.1 Micro-mineral additives A type of nutritional additives artificially added to meet the needs of livestock and poultry for mineral nutrition during the breeding process. 3.2 Organic trace elements Simple complexes or chelates formed by covalent or ionic bonds between metal elements and organic ligands, such as proteins, amino acids, organic acids, small peptides, polysaccharides, and their derivatives. 3.3 Biological organic trace elements A type of organic trace elements synthesized by microbial fermentation. 3.4 Element tolerance ability The ability of a certain microorganism to grow on a medium containing one or more trace elements (with trace element concentrations far exceeding actual needs) 3.5 Microbial acclimation A cultivation process in which the growth environment of microorganisms is controlled by artificial means to achieve the desired performance goals. 3.6 Fermentation substrate An artificial product made by mixing agricultural by-products, manufacturing by-products, and other nutrients to meet the needs of microorganism growth, reproduction, and product synthesis. 3.7 Bacterial counts The number of viable bacteria in a certain volume or mass of fermentation products measured by the method of bacterial counting. 3.8 Moisture content The ratio of the weight of wat
