All technical contents of this standard are mandatory. Former
This standard is separated from GB14924--1994 "Complete Nutrient Feed for Laboratory Animals" to form an independent standard. This standard revises the indicators of crude protein and crude fat in conventional nutrients and adds the indicator of calcium-phosphorus ratio. It revises the indicators of vitamin D, vitamin K, vitamin B1, B2, B3, niacin and pantothenic acid in amino acids and vitamins. It adds the indicators of folic acid, biotin and choline. It adds the indicators of sodium and selenium in minerals and trace elements. This standard and its supporting standards replace GB14924-1994 from the date of implementation. This standard is proposed and registered by the Ministry of Science and Technology of the People's Republic of China. The initiator of this standard: Chinese Society of Laboratory Animal Science. The main drafters of this standard: Su Wei, Liu Sumei, Liu Yuan, Zhang Yu, Zhou Ruihua, Zheng Tao and Liu Xiumei. This standard was issued by the Ministry of Science and Technology of China, which is responsible for the interpretation of the technical coordination unit, the Chinese Society of Laboratory Animals. This standard was first issued in January 1994.
