RONOZYME® WX improves the digestibility of wheat, rye, triticale, barley and cereal by-products, and results in better-performing poultry and swine. RONOZYME® WX is an exceptional mono-component xylanase product used for both intestinal viscosity reduction and nutrient release from cereals and cereal by-products. Ronozyme® WX contains xylanase. The product is authorized for use in the EU in poultry for fattening, piglets and pigs for fattening. Ronozyme® WX is available both as a dry application (CT) (Powder) or as a liquid application (L) (Liquid).

Features & Benefits

Product Highlights
  • RONOZYME® WX degrades both soluble and insoluble xylans, a key part of the cell wall structure in cereals. The degradation of the insoluble cell wall results in the release of vital nutrients trapped in the intact plant cells, and the degradation of the soluble xylan significantly reduces the viscosity of intestinal content. In both cases, the result is increased nutrient availability and digestibility.
  • Metabolic energy is significantly increased, e.g., 3% in corn and 6% in wheat in broiler diets.

RONOZYME® WX in swine

When incorporated into swine diets, RONOZYME® WX increases weight gain and improves feed conversion. The result is faster-growing, more efficient and more profitable animals.

RONOZYME® WX in poultry

Supplementing the diets of broiler chicken with RONOZYME® WX will improve the efficiency of feed utilization and reduce feed costs while increasing growth rates. It also improves the consistency of litter, improving the environment for poultry.

Storage & Handling

Storage Stability

At a temperature of 25°C the product maintains its activity for at least 12 months from the date of manufacture

Storage stability in feed

No significant losses were observed when feed supplemented with Ronozyme WX was stored at temperatures up to 25°C for three months


RONOZYME® WX is an exceptional heat-stable xylanase and our specific CT (coated thermo stable) formulation. It is free-flowing and dust-free, ensuring reduced losses during feed manufacture and making it suitable for most feed production processes.

Heat stability

More than 80% of the xylanase activity was left when the feed was pelleted at 95°C (Rasmussen, 2010)


Avoid ingestion, inhalation of dust or direct contact by applying suitable protective measures and personal hygiene
