This standard is not applicable to 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 colony forming units (CFU)/g;b) Premixtures containing about 10 CFU/g;c) Feeds, meal or pellets, which contain about 10 CFU/g and include complete feeding stuffs and milkreplacers.The detection limit is as defined in EN ISO 7218.【中国标准分类号】: B46【国际标准分类号】: 65_120【页数】: 20P.;A4【正文语种】: 英语
