적용 범위

This standard applies to frozen semen products derived from both goats and sheep. It establishes the essential technical requirements, sampling procedures, and inspection rules for these biological products within China's animal husbandry sector. Manufacturers and suppliers of livestock reproductive materials must comply with these provisions to ensure market access. It replaces the previous GB 20557-2006 standard, expanding its scope to explicitly include both species.

기술 요구 사항

GB 20557-2025 specifies critical quality parameters for frozen semen to ensure reproductive efficacy and biosafety. The standard mandates strict thresholds for dosage volume, ensuring each straw contains an adequate volume of semen. It also sets minimum limits for sperm motility and the number of progressively motile sperm per dose, which are vital indicators of fertilization potential. Furthermore, the standard imposes maximum allowable limits for sperm abnormality percentage and aerobic plate count (total bacterial count) to prevent disease transmission and ensure genetic health. Compliance with these specified parameter limits is mandatory for all market batches. Additionally, the standard outlines specific requirements for accompanying documentation, including pedigree and production performance records of the donor ram.

시험 방법

The standard outlines specific laboratory procedures to evaluate the required technical parameters. Key testing methods include microscopic evaluation for sperm motility and morphological assessment for identifying abnormal sperm. The number of progressively motile sperm is determined using a hemocytometer counting chamber method. For biosafety, the aerobic plate count is conducted using nutrient agar cultivation in accordance with GB 4789.2. Strict sampling protocols, including the use of specialized liquid nitrogen biological containers, are mandated to maintain sample integrity during extraction and transportation.

자주 묻는 질문

What products are regulated under GB 20557-2025?

GB 20557-2025 applies to frozen semen products of both goats and sheep. It replaced the previous GB 20557-2006 standard, which only covered goat frozen semen, thereby expanding its regulatory scope.

Are there any major updates from the previous version of GB 20557?

The 2025 revision includes the addition of new terms such as abnormal sperm and batch, modified requirements for sperm motility and progressively motile sperm count, and the introduction of new regulations for dosage and the disposal of non-conforming products.

How does GB 20557-2025 relate to other international or national standards?

The standard references several national standards for its testing methodologies and packaging requirements, such as GB 4789.2-2022 for aerobic plate count determination and GB/T 30396 for packaging, labeling, storage, and transportation guidelines.
