Scope

Scope: This document specifies the terms and definitions, basic requirements, technical requirements, test and calculation methods, inspection, marking, packaging, transportation, and storage for feed-use controlled-release coated preparations. This document applies to five types of feed-use controlled-release coated preparations: full-intestinal controlled-release preparations, enteric-coated preparations, colon-targeted preparations, rumen-resistant preparations, and rumen-controlled-release preparations. This document does not apply to preparations that are simply granulated after mixing auxiliary materials such as starch and dextrin and do not possess controlled-release functions. Main technical content: 4.1 Raw material requirements: The varieties of raw materials used in feed-use controlled-release coated preparations shall be within the scope specified in the *Feed Raw Materials Catalog* and the *Feed Additives Variety Catalog*. 4.2 Sensory requirements: Feed use controlled-release coated preparations shall not contain impurities, no other colored particles shall be mixed in, and the color shall be uniform and consistent. The form shall be granular or powdery, and no lumping shall be allowed. There shall be no other irritating odors except those from the raw materials. 4.3 Quality requirements 4.3.1 Physicochemical indicators 4.3.2 Hygiene indicators 5 Technical requirements 5.1 Solvents 5.2 Formulation and process 5.3 Release rate 5.4 Product stability
