DIN EN 15785-2009牲畜飼料.雙歧桿菌的分離和計數,德文版本EN 15785:2009

This European standard defines general rules for the enumeration of probiotic bifidobacteria in feed samples (additives, premixtures and feeding stuffs) that contain bifidobacteria as a single bacterial component or in a mixture with other microorganisms. This standard is not applicable for mineral feeds which are defined as complementary feeding stuffs composed mainly of minerals and containing at least 40% crude ash (Council Directive 79/373/EEC).

BS EN 15785-2009動物飼料.雙岐桿菌屬的分離和計數

This European Standard defines general rules for the enumeration of probiotic bifidobacteria in feed samples(additives, premixtures and feeding stuffs) that contain bifidobacteria as a single bacterial component or in amixture with other microorganisms. This standard is not applicable for mineral feeds which are defined ascomplementary feeding stuffs composed mainly of minerals and containing at least 40% crude ash (CouncilDirective 79/373/EEC) [3].There are different categories of feed samples:a) Additives containing about 10<(UP)10> colony forming units (CFU)/gb) Premixtures containing about 10<(UP)8> CFU/gc) Feeds, meal or pellets, which contain about 106 CFU/g and include complete feeding stuffs, and milkreplacers.The detection limit is as defined in EN ISO 7218.
