This standard replaces GB/T 7301-2002 "feed additive nicotinamide." This standard compared with GB/T 7301-2002, the main technical differences are as follows:

--- Revised the "content" of the determination;

--- Revised the "heavy metals" detection methods;

--- Increase the "total arsenic" limited requirements and testing methods;

--- The "moisture" determination of Karl Fischer's method was changed to dry weight loss determination, the revised target is <= 0.5%. This standard is proposed and managed by the National Feed Industry Standardization Technical Committee (SAC/TC76). This standard drafting unit. Shanghai Veterinary Drug Feed Inspection Institute, China Feed Industry Association, Guangzhou Longsha Ltd., Zhejiang Pharmaceutical Co., Ltd. Limited company. The main drafters of this standard.
