Raw materials

As a feed manufacturer, you will want rapid assurance about the quality of the raw materials used. For optimal feed formulation, you will need to know the actual nutrient levels. TLR, naturally, offers the complete analysis of Weende components in your raw materials - but that's not all.


In addition to chemical analyses, TLR can also quickly determine mycotoxins and microbiological quality and safety. The usual causes of microbiological contamination of raw materials are insufficient hygiene and climate control during storage or transport. Moulds, yeast and bacteria in raw materials are usually killed in the feed compounding process, but for quality assurance you will want to know about the microbiological quality of your raw materials. TLR can also help you with this as we determine the presence of, amongst other things, Salmonella, Campylobacter and Enterobacteriaceae. If desired, TLR can also determine the microbiological quality of crops during cultivation. If crops become contaminated with fungi during cultivation or storage, mycotoxins can be formed that pose a threat to animal health.


TLR can also offer analysis of physical and (bio) chemical contaminants in raw materials. Heavy metals, dioxins, pesticides and PCBs are examples of contaminants for which there are action limits and rejection limits. It is therefore important to monitor the levels of raw materials.


Obviously, high reliability is essential for an analytical laboratory such as TLR.

TLR is GMP+ and QS certified and ISO 17025 accredited (L059). Because we are also approved by FOSFA and GAFTA, our reports are recognised internationally. With our wide range of analyses, we also support companies working with quality schemes.
