Enterobacteriaceae contamination in feed can threaten animal health. Especially high protein materials, such as soy, corn by-products, and blood and bone meals are susceptible to harmful pathogens, such as Salmonella, E.coli, moulds and yeasts.

The Fysal product range is part of various Selko programmes, aiming to prevent and reduce the presence of microbes that can degrade the nutritional value of feed.  

Product application

Fysal products should be applied in feed ingredients, compound feed or feed residues, in order to reduce the risk of harmful microbes and to prevent (re-)contamination. It can be used both as preventive or corrective action. 

The Fysal range offers multiple products, suited for various steps of the feed production process. Contact your Trouw Nutrition representative to discuss which product is suitable for your situation.
