dsm-firmenich is excited to announce that its leading Xylanase enzyme RONOZYME WX has recently received an extension of registration and use in to laying hens and lactating sows in EU27. RONOZYME WX was already registered in the EU27 for broilers, piglets and swine for both growing and finishing phases. This is great news for dsm-firmenich customers as they now get even more flexibility to use this innovative enzyme to optimize their feed milling activities.
RONOZYME WX is recognized across the industry as an outstanding mono-component Xylanase product, due to its excellent performance in swine and broiler diets. It markedly improves the digestibility of wheat, corn, rye, triticale, barley and cereal by-products through degradation of both soluble and insoluble xylans, the major antinutritional component present in the cell wall structure of cereals. Degradation of soluble xylans by RONOZYME WX significantly reduces the viscosity of intestinal content whereas action on the insoluble fraction improves access of starch and protein to the animals endogenous enzymes. Short chain xylan oligomers produced as a consequence of xylanase action are also demonstrated to have a positive effect on the microbiota and health status of the intestinal tract. The net effect of using RONOZYME WX is an increased metabolic energy release by on average 3% in corn and 5% in wheat plus and an increase in amino acid digestibility of 1.5-2% respectively.
When incorporated into laying hen diets, RONOZYME WX improves performance, with a higher laying rate and egg mass production, as well as a significantly better feed to egg ratio. RONOZYME WX also positively improves consistency of manure and reduces ammonia emission , improving welfare of laying hens, reducing the impact on the environment and contributing to hygiene status of eggs produced by reducing the number of dirty eggs.
Robust testing of RONOZYME WX in a variety of layer diets has demonstrated a significant overall improvement in bird productivity, such as an increase in egg production (2-3%) and egg mass (+2-4%). RONOZYME WX also generated a significant reduction in FCR (-2% - 4.5%) and gave a significant decrease in dirty eggs (-14% to -17%).
When incorporated into lactating sow diets, RONOZYME WX has been shown to significantly reduce bodyweight and backfat losses. Results are associated with an increased feed intake during lactation and better nutrient digestibility with consequent reduction in tissue mobilization. Trials with different diet compositions in leading European experimental facilities showed significant (P<0.001) increases in Apparent Total Tract Digestibility (ATTD) % of dry matter, organic matter & gross energy (+3% to 4%) and up to a 60% reduction in weekly body weight loss.
RONOZYME WX also meets the highest manufacturing quality standards, being an exceptional heat-stable xylanase available in liquid and powder form. A state-of-the-art Coated Thermo (CT) stable product formulation is used for protecting the powder form. It is free-flowing and dust-free, ensuring minimum loss of activity during feed manufacture and making it suitable for most feed production processes.
Improving digestibility of the cereal fraction of the diet is key to optimizing performance and improving sustainability of animal production. dsm-firmenich’s leading xylanase RONOZYME WX has consistently delivered outstanding performance in broilers, piglets and swine for both growing and finishing phases. With approval for use in laying hens and lactating sows these benefits can now be replicted in all major monogastric species.
