ISO 30024:2024 动物饲料 肌醇六磷酸酶活性的测定

标准编号：ISO 30024:2024

中文名称：动物饲料 肌醇六磷酸酶活性的测定

英文名称：Animal feeding stuffs — Determination of phytase activity

发布日期：2024-04

标准范围

本文件规定了饲料样品中植酸酶活性的测定，包括植物来源的饲料原料、配合饲料（完全饲料、补充饲料、矿物质饲料）、预混料和饲料添加剂。该方法适用于测定完全饲料、补充饲料（包括矿物质饲料）、预混料和饲料添加剂中的植酸酶活性，并得到了协同验证。该方法不区分作为饲料添加剂添加的植酸酶和已经存在于饲料材料中的内源性植酸酶。因此，该方法也适用于来自植物来源的饲料材料。该方法不适用于评估或比较植酸酶产品的体内功效。它不是市场上存在的植酸酶体内功效的预测方法，因为它们每单位活性可以产生不同的体内功效。

This document specifies the determination of phytase activity in feeding stuff samples, including feed raw materials from plant origin, compound feeds (complete, complementary, mineral feeds), premixtures and feed additives.

The method is applicable to, and is collaboratively validated for, the determination of phytase activity in complete feed, complementary feed including mineral feed, premixtures and feed additives.

The method does not distinguish between phytase added as a feed additive and endogenous phytase already present in the feed materials. Therefore, the method is also applicable for feed materials from plant origin.

The method does not apply to evaluating or comparing the in vivo efficacy of the phytase product. It is not a predictive method of the in vivo efficacy of phytases present on the market as they can develop different in vivo efficacy per unit of activity.
