This standard covers the determination of potassium dihydrogen phosphate in acidity requlators used as feed additives by the titrimetric method.
This European Standard specifies a high performance liquid chromatography (HPLC) method for thedetermination of the content of maduramicin in feeding stuffs and premixtures.The usual concentration of maduramicin in feedstuffs is 5 mg/kg, in premixtures 500 mg/kg. The limit ofquantification is 2 mg/kg. The limit of detection is 0,5 mg/kg.NOTE A lower limit of quantification may be achievable but shall be validated by the user.
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).
This International Standard specifies the determination of phytase activity in feed samples.The method does not distinguish between phytase added as a feed additive and endogenous phytase alreadypresent in the feed materials,The method cannot be used to evaluate or compare the in vivo efficacy of the phytase product, It is not apredictive method of the in vivo efficacy of phytases present on the market as they can develop differentin vivo efficacy per unit of activity,The method is suitable and validated exclusively for the determination of phytase activity and exclusively incomplete feeds,NOTE The harmonized method was developed on the basis of the presently existing phytase products[E1600 (EC 3.1,3,8, 3-phytase), E1614 (EC 3,1,3,26, 4-phytase), and E1640 (EC 3.1,3,26, 4-phytase)]. Therefore, it mightnot necessarily be suitable as such for phytase products that are developed in the future, The harmonized method is thusa tool which is useful only to evaluate the total phytase activity in feed samples,

This European Standard defines general rules for the enumeration of probiotic bacilli in feeds containing bacilli(Bacillus species) as a single microorganism, component or mixed with other microorganisms. This method isnot applicable to mineral feeds which are defined as complementary feeding stuffs composed mainly ofminerals and containing at least 40% crude ash (Council Directive 79/373/EEC) [3].There are different categories of feed samples:a) Additives containing about 1010 colony forming units (CFU)/g;b) Premixtures containing about 108 CFU/g;c) Feeds, meal or pellets, which contain about 106 CFU/g and include complete feeding stuffs, and milkreplacers.The detection limits are 500 (5 x 102) colony forming units per gram (CFU/g). The limits of determination are2 x 104 CFU/g.
