Requisitos técnicos

The standard specifies the terminology, classification, and quality indicators for parent eggs of silkworm. It categorizes the eggs into Chinese system and Japanese system based on the silkworm strain. The technical requirements cover both appearance and packaging as well as egg quality indicators. For appearance and packaging, the standard mandates specific minimum numbers of good eggs per moth, a minimum net conversion rate, and proper labeling including variety name, batch number, and production unit. Each sheet of parent eggs must have a certificate of conformity attached. For egg quality, the standard regulates parameters such as the number of good eggs per sheet, the good egg rate, practical hatching rate, disease egg rate, and purity. These metrics ensure the biological viability and health of the silkworm eggs. The standard also references *GB/T 19178* for the detailed testing procedures. Additionally, the standard includes a normative annex detailing production process pre-control requirements. This covers the entire lifecycle from rearing to moth selection, emphasizing the elimination of diseased or non-conforming individuals and strict control over pebrine disease (microsporidiosis) through group testing of mother moths.
