标准摘要
[中文适用范围]： 此文件规定了饲料样品中植酸酶活性的测定，包括植物起源的饲料原料、复合饲料（全价、补充、矿物质饲料）、预混料和饲料添加剂。该方法适用于并已协同验证用于测定全价饲料、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。该方法不区分作为饲料添加剂添加的植酸酶与饲料原料中已经存在的内源性植酸酶。因此，该方法也适用于植物起源的饲料原料。此方法不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按单位活性体内功效的预测方法，因为它们在单位活性下可能表现出不同的体内功效。 [外文原描述]： 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.
