Scope: This standard specifies the environmental conditions, technical requirements, and production management methods for the production of pure natural selenium-enriched mulberry egg chicken feed. This standard applies to the production of pure natural selenium-enriched mulberry egg chicken feed. Main technical content: Environmental conditions, technical requirements, and production management methods for the production of pure natural selenium-enriched mulberry egg chicken feed. Using mulberry leaves produced on selenium-rich soil and adding them to egg chicken feed at a certain proportion can ensure that the selenium content in the feed meets the requirements for the production of selenium-enriched egg chickens as raw materials or additives. According to the nutritional needs of egg chickens at different growth stages, formulate compound feed with corresponding nutritional levels. In compound feed or fully mixed feed, the maximum total selenium limit is 0.5 mg/kg.
