Foreword

The first chapter of this standard, Chapter 3 and Chapter 5 is mandatory, the rest are recommended. This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed and managed by the National Feed Industry Standardization Technical Committee (SAC/TC76). This standard drafting unit. China Agricultural University, China Feed Industry Association, Changchun Dacheng Industry Group Co., Ltd.. The main drafters of this standard. Shi Shi Yan, Fuqing, Wang Dehui, He Ping Li, Xie Chunyuan, had Xiangfang. Feed additive L-lysine hydrochloride

1 Scope

China's mandatory standard for L-lysine monohydrochloride used as a feed additive - the single most important amino acid supplement in animal nutrition, and one of the largest fermentation products made anywhere. Lysine is the first limiting amino acid in the cereal-based diets fed to pigs and poultry: the animal can use the protein in the ration only up to the point where the lysine runs out, and everything above that is excreted as nitrogen. Adding pure lysine lets a formulator cut the crude protein of the diet substantially while keeping performance, which saves soya and reduces the nitrogen leaving the farm - so this additive is as much an environmental measure as a nutritional one. The standard specifies the requirements, the test methods, the inspection rules and the labelling, packaging, transport, storage and shelf life of feed additive L-lysine monohydrochloride. The requirements cover the assay, the specific optical rotation - which is the requirement that matters most, since only the L form is biologically active and the D form is inert, so an optical purity failure is a product that assays correctly and does not feed - the appearance, the loss on drying, the residue on ignition, the pH of the solution, the chloride content and the particle size, together with the limits on the heavy metals and on the residues carried over from the fermentation and the recovery. The feed hygiene limits of GB 13078 apply throughout. Issued on 14 October 2017 and in force since 1 May 2018.
