Область применения
This standard applies to formula feeds for laboratory animals, covering species such as mice, rats, guinea pigs, hamsters, rabbits, dogs, and monkeys. It categorizes feeds into maintenance feeds and growth and reproduction feeds. This standard does not apply to special feeds required for animal models. It is essential for manufacturers and research facilities supplying animal feed within the Chinese market.
Технические требования
This standard specifies the comprehensive nutritional requirements for laboratory animal feeds, integrating previous separate standards into one unified document. Certain indicators for conventional nutrients and specific amino acids like lysine and methionine + cystine are mandatory. The standard defines strict parameter categories including conventional nutrients (such as crude protein, crude fat, and crude fiber), amino acid profiles, vitamins (fat-soluble and water-soluble), and macro and micro minerals. All nutritional values are standardized and expressed in grams per kilogram (g/kg) or milligrams per kilogram (mg/kg). A key technical regulation in this standard is the establishment of a maximum upper limit for vitamin and mineral contents. The maximum upper limit for these micronutrients is strictly set at twice the value of the established lower limit. This ensures nutritional safety and prevents hypervitaminosis or mineral toxicity in laboratory animals.
Методы испытаний
Nutritional component testing must be conducted in accordance with the referenced GB/T 14924.9 to GB/T 14924.12 standards. These cover the analytical methods for determining conventional nutrients, amino acids, vitamins, and mineral elements. Manufacturers must verify their feed formulations against these specified testing protocols to ensure regulatory compliance.
