96/25/EC - Council Directive 96/25/EC of 29 April 1996 on the circulation of feed materials, amending Directives 70/524/EEC, 74/63/EEC, 82/471/EEC and 93/74/EEC and repealing Directive 77/101/EEC

This part of ISO 16634 specifies a method for the determinatio n of the total nitrogen content and the calculation of crude p rotein content of oilseeds and animal feeding stuffs. This met hod, like the Kjeldahl method, does not distinguish between pr otein nitrogen and non-protein nitrogen. For the calculation o f protein content, various conversion factors are used (see An nex D).

ISO 16634-1:2008 specifies a method for the determination of the total nitrogen content and the calculation of crude protein content of oilseeds and animal feeding stuffs.
This method, like the Kjeldahl method, does not distinguish between protein nitrogen and non-protein nitrogen. For the calculation of protein content, various conversion factors are used.
This method is not applicable to milk and milk products.

This Technical Specification describes the quantitative determination of specific sugars (glucose, fructose, galactose, sucrose, maltose, and lactose) in dry animal feeding stuffs at the g/kg level by a sophisticated high performance anion exchange chromatography in combination with pulsed amperometric detection (HPAEC-PAD).

ISO 15914:2004 specifies a method for the enzymatic determination of the total starch content of animal feeding stuffs and raw materials for animal feeding stuffs.
The method is also applicable to the determination of starch in starch.
It is important that in the sample matrix no components are present which contribute to the measured extinction at 340 nm.
The analytical range of the method is 40 g/kg to 1 000 g/kg starch. The standard procedure is applicable to the range 200 g/kg to 1000 g/kg. For the lower range, 40 g/kg to 200 g/kg, another dilution procedure for the standard glucose solution and samples can be used.
