This standard is not applicable to mineral feeds which are defined ascomplementary feedingstuffs 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 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】: 18P.;A4【正文语种】: 英语
