class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Corn and wheat are principal ingredients in broiler diets worldwide. They also contain high levels of arabinoxylans, the main non-starch polysaccharides in cereal cell walls.\u2076\u02d2\u2077 These arabinoxylan-rich structures can encapsulate starch and protein, restricting access by endogenous enzymes\u2014particularly in young birds, whose digestive capacity is still developing.\u2075<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The effects of arabinoxylans depend on their structure and solubility. Soluble fractions can increase digesta viscosity, while insoluble fractions contribute to the physical encapsulation of nutrients. Together, these effects can limit nutrient utilization unless the arabinoxylans are effectively degraded.\u00b9<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Arabinoxylans have traditionally been viewed as antinutritional components to be neutralized. However, this perspective overlooks their potential value. When effectively broken down, they release functional oligosaccharides that beneficial gut bacteria can ferment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The opportunity, then, lies in unlocking this fiber efficiently so that it can support gut health and performance.<\/p>\n\n\n\n<h2 id=\"h-how-danisco-xylanase-enzyme-supports-poultry-gut-health-beyond-digestibility\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Danisco%C2%AE_Xylanase_Enzyme_Supports_Poultry_Gut_Health_Beyond_Digestibility\"><\/span>How Danisco<sup>\u00ae<\/sup> Xylanase Enzyme Supports Poultry Gut Health Beyond Digestibility<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Danisco<sup>\u00ae<\/sup> Xylanase is <a href=\"https:\/\/www.iff.com\/es\/our-science\/\" data-type=\"link\" data-id=\"https:\/\/www.iff.com\/our-science\/\" target=\"_blank\" rel=\"noreferrer noopener\">designed<\/a> to act at the optimal pH and location in the gastrointestinal tract, enabling efficient arabinoxylan degradation in cereal-based diets.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the upper gut, this results in well-established benefits:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cleavage of arabinoxylans<\/li>\n\n\n\n<li>Reduced digesta viscosity in diets containing wheat or other viscous cereals<\/li>\n\n\n\n<li>Improved nutrient release<\/li>\n\n\n\n<li>Increased nutrient absorption at the site of uptake<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">However, its effects are not limited to the upper gut. Early hydrolysis of arabinoxylans not only improves immediate nutrient access but also influences the type and quantity of fiber fragments that reach the lower gut.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Danisco<sup>\u00ae<\/sup> Xylanase enzyme breaks down arabinoxylans found in cereals to generate small fiber fragments called arabinoxylo-oligosaccharides (AXOS). These AXOS:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Resist host digestion<\/li>\n\n\n\n<li>Reach the lower gut intact<\/li>\n\n\n\n<li>Serve as substrates for beneficial bacteria<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">By generating AXOS, Danisco<sup>\u00ae<\/sup> Xylanase enzyme helps shape the substrates available to microorganisms in the hindgut. This contributes to a prebiotic-like effect that supports microbial fermentation and gut function alongside feed efficiency, linking enzyme activity in the upper gastrointestinal tract to microbial responses farther along the digestive system.<\/p>\n\n\n\n<h2 id=\"h-why-xylanase-inclusion-level-influences-outcomes-in-broilers\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Xylanase_Inclusion_Level_Influences_Outcomes_in_Broilers\"><\/span>Why Xylanase Inclusion Level Influences Outcomes in Broilers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Xylanase inclusion level plays an important role in determining functional outcomes in broilers. At lower inclusion levels, the primary effect is typically arabinoxylan cleavage and improved nutrient release. At higher inclusion levels, more extensive arabinoxylan hydrolysis may generate more AXOS and exert a stronger influence on microbial activity in the lower gut.\u00b2\u02d2\u2078<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This represents a shift from effects driven mainly by digestibility toward a combination of digestive and microbiome responses. It is especially relevant in young broilers, where increased digestive capacity and early microbial colonization can together influence long-term performance.<\/p>\n\n\n\n<h2 id=\"h-axos-profile-and-microbial-cross-feeding-why-enzyme-specificity-matters\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"AXOS_Profile_and_Microbial_Cross-Feeding_Why_Enzyme_Specificity_Matters\"><\/span>AXOS Profile and Microbial Cross-Feeding: Why Enzyme Specificity Matters<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The functional effects of xylanase enzyme depend on the types and size distribution of the oligosaccharides produced. Danisco<sup>\u00ae<\/sup> Xylanase generates a spectrum of AXOS, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Short-chain AXOS and XOS<\/strong>: Rapidly fermented by primary bacterial fermenters, producing acetate and lactate<\/li>\n\n\n\n<li><strong>Longer-chain AXOS<\/strong>: Fermented more slowly, reaching the ceca, where they support butyrate-producing bacteria<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This balance drives microbial cross-feeding, in which metabolites produced by one bacterial group are utilized by others, resulting in a sustained increase in butyrate production and improvement in gut barrier integrity.\u2079<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practical terms, the result is a more stable and sustained fermentation pattern rather than short-lived fluctuations. This is particularly relevant during early gut development, when microbial populations are still becoming established.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1181\" height=\"531\" src=\"https:\/\/www.iff.com\/wp-content\/uploads\/2026\/09\/1-1.jpg\" alt=\"\" class=\"wp-image-56724\" srcset=\"https:\/\/www.iff.com\/wp-content\/uploads\/2026\/09\/1-1.jpg 1181w, https:\/\/www.iff.com\/wp-content\/uploads\/2026\/09\/1-1-300x135.jpg 300w, https:\/\/www.iff.com\/wp-content\/uploads\/2026\/09\/1-1-767x345.jpg 767w, https:\/\/www.iff.com\/wp-content\/uploads\/2026\/09\/1-1-1024x460.jpg 1024w, https:\/\/www.iff.com\/wp-content\/uploads\/2026\/09\/1-1-400x180.jpg 400w, https:\/\/www.iff.com\/wp-content\/uploads\/2026\/09\/1-1-200x90.jpg 200w\" sizes=\"auto, (max-width: 1181px) 100vw, 1181px\" \/><figcaption class=\"wp-element-caption\"><em>Proposed microbial cross-feeding pathway following xylanase enzyme-mediated breakdown of cereal arabinoxylans.

Even incremental gains at this stage can influence flock uniformity and final performance outcomes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This alignment between digestive efficiency, microbiome modulation, and gut integrity markers indicates that Danisco<sup>\u00ae<\/sup> Xylanase contributes to performance through multiple, complementary mechanisms.<\/p>\n\n\n\n<h2 id=\"h-implications-for-broiler-nutrition-strategies\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Implications_for_Broiler_Nutrition_Strategies\"><\/span>Implications for Broiler Nutrition Strategies<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For nutritionists, these findings support a broader view of Danisco<sup>\u00ae <\/sup>Xylanase enzyme, not only as a tool for nutrient release but also as part of a gut functionality strategy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This broader role is particularly relevant in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Antibiotic-free production systems<\/li>\n\n\n\n<li>Diets with variable fiber composition<\/li>\n\n\n\n<li>Situations requiring improved early gut development and robustness<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-rethinking-the-role-of-xylanase-enzyme-in-broiler-nutrition\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Rethinking_the_Role_of_Xylanase_Enzyme_in_Broiler_Nutrition\"><\/span>Rethinking the Role of Xylanase Enzyme in Broiler Nutrition<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Xylanase remains a key enzyme for improving feed efficiency. At higher inclusion levels, Danisco\u00ae Xylanase enzyme extends this traditional role by supporting microbial activity, fiber utilization, and gut function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For nutritionists, this broader functionality can mean more gain from the same feed, greater robustness during the high-risk early phase, and more predictable performance later in the production cycle. These outcomes are increasingly important as production systems face growing demands for consistency and resilience.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Taken together, these findings support viewing xylanase enzyme not as a single-purpose enzyme focused mainly on nutrient release but as a <a href=\"https:\/\/www.iff.com\/es\/media\/stories\/optimizing-phytase-animal-feed\/\" target=\"_blank\" rel=\"noreferrer noopener\">multifunctional contributor<\/a> to gut health and performance.<\/p>\n\n\n<div class=\"m-block blog-cta\"  style='--inline-cta-pretitle-text-transform: uppercase;'>\n            <div class=\"blog-cta__content\">\n                                        <div class=\"blog-cta__title\">\n                    See how Axtra\u00ae PHY GOLD phytase supports feed efficiency in poultry and swine                <\/div>\n                    <\/div>\n                <a href=\"https:\/\/www.iff.com\/es\/media\/stories\/phytase-enzyme-feed-efficiency-poultry-swine\/\" target=\"_blank\" class=\"c-btn -normal -primary has-icon icon-right\">Learn More <svg width=\"30\" height=\"30\" class=\"icon icon-lib-icon-arrow1\" aria-hidden=\"true\" role=\"img\"><use xlink:href=\"#lib-icon-arrow1\"><\/use><\/svg><\/a>    <\/div>\n\n\n\n<h2 id=\"h-references\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"References\"><\/span>References<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Choct, M.
