コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard specifies the quality technical requirements, sampling, test methods, inspection rules, labeling, packaging, storage, and transportation for commercial boar liquid semen products. It is strictly applicable to commercialized liquid semen products used for artificial insemination in pig breeding. It does not apply to frozen semen or raw, undiluted semen. The standard categorizes requirements based on the insemination method (conventional vs. deep) and breed type (introduced/cultivated vs. local).

技術要求

The standard establishes mandatory quality parameters for boar liquid semen to ensure artificial insemination success. Key technical requirements include specific limits for dosage volume, which varies depending on whether the semen is intended for conventional or deep insemination. Another critical parameter is sperm motility, expressed as the percentage of progressively moving sperm at approximately 37°C. The standard also dictates the minimum number of progressively motile sperm per dose, ensuring sufficient viable sperm for fertilization. Furthermore, it sets a maximum threshold for sperm abnormality rate, restricting the percentage of morphologically defective sperm (e.g., large heads, coiled tails). Manufacturers must ensure all batches meet these tiered specifications based on breed and application. Additionally, the standard outlines requirements for packaging materials to be non-toxic, storage conditions (16°C~18°C), and a minimum shelf life of 72 hours.

試験方法

The standard prescribes specific testing methodologies to verify compliance. Dosage is determined by weighing the product and subtracting the empty packaging weight. Sperm motility and sperm concentration are evaluated using a computer-assisted sperm analysis (CASA) system, specifically a sperm quality analyzer with a phase-contrast microscope. For sperm abnormality rate, two staining methods are detailed: the Giemsa staining method (serving as the arbitration method) and the Eosin-Nigrosin rapid staining method. Laboratories must follow these standardized procedures to ensure accurate and reproducible quality assessments. The standard also includes a calibration method for the sperm quality analyzer using a hemocytometer.

よくある質問

What products are regulated under GB 23238-2021?

GB 23238-2021 regulates commercial boar liquid semen products. It applies to diluted, liquid semen stored at room temperature (16°C~18°C) and sold for artificial insemination. It does not cover frozen semen.

Are there any updates from the previous version of GB 23238?

Yes, compared to GB 23238-2009, this version introduces requirements for deep insemination, adds definitions for terms like "batch" and "shelf life," and updates the testing methods for dosage and motility. It also includes new provisions for accompanying documents and the disposal of non-conforming products.

What are the storage and shelf life requirements under this standard?

The standard mandates that boar liquid semen must be stored in a thermostatic box at 16°C~18°C, protected from light, and shaken every 8 to 12 hours. Manufacturers must specify a shelf life, which must be no less than 72 hours.

The summary above provides a high-level overview of GB 23238-2021.
