What is BS EN 16159 - Selenium in animal feeding stuffs about?
BS EN 16159 is a European standard that serves technical specifications for Selenium in animal feeding stuff that forms part of enzymes and other proteins in animal tissues leading to better health and productivity in animals.
BS EN 16159 specifies a method for the determination of selenium in animal feeding stuffs by hydride generation atomic absorption spectrometry (HGAAS) after microwave pressure digestion.
BS EN 16159 method was successfully tested by an inter-laboratory study of CEN/TC 327/WG 4 in the range of 0.25 mg/kg to 74 mg/kg.
BS EN 16159 method specifies the limit of quantification is 0.5 μg/l of the test solution, which corresponds to the calibration standard 2. Using a test portion of 0.5 g and a volume of the test solution of 25 ml after pressure digestion, the limit of quantification is calculated as 0.125 mg/kg in the feed material.
Who is BS EN 16159 - Selenium in animal feeding stuffs for?
BS EN 16159 on Selenium in animal feeding stuffs applies to:
- Manufacturers of animal feeds
- Dealers and importers of animal feeds
- Testing labs for animal feeds
- Safety assurance services
- Regulatory bodies
Why should you use BS EN 16159 - Selenium in animal feeding stuffs?
Selenium deficiency can cause various diseases in animals and lead to decreased productive and reproductive performance of farm animals. Optimisation of Selenium nutrition in poultry and farm animals promotes the efficiency of egg, meat and milk production.
BS EN 16159 provides users guidance on the hydride generation atomic absorption spectrometry (HGAAS) method for determining selenium in animal feeds. BS EN 16159 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.
BS EN 16159 provides users guidance on principle, reagents, apparatus, equipment, procedure, HGAAS determination, calculation, precision and test report, enabling the prevention and treatment of selenium deficiency in animals.
With obedience and compliance to BS EN 16159, users can accurately determine selenium content in animal feeds, ensuring the nutritional value of feeds for vitality and improved performance in animals.
