Xygest™ HT – Heat-Stable Xylanase for Nutrient Utilization

Xygest™ HT is an intrinsically thermostable xylanase developed for animal feed exposed to high-temperature processing. Its xylanase activity helps break down non-starch polysaccharides, while intrinsic heat stability supports enzyme delivery across swine and poultry diets.

Features and Benefits of Xygest HT

  • Intrinsic Heat Stability: Intrinsically thermostable xylanase helps maintain enzyme activity under high-temperature feed-conditioning and pelleting conditions.
  • Improved Feed Efficiency: Research in broilers and layers supports improved feed conversion with Xygest HT supplementation.
  • Prebiotic-Like Effects: Xylan breakdown supports in-situ generation of oligosaccharides, with research showing increased short-chain fatty acids and positive changes in gut morphology.
  • Flexible Formulation Strategies: Xygest HT can be used on top to support performance or with feed reformulation to reduce feed costs.

Improving Nutrient Utilization by Targeting Xylan

Xylan-containing non-starch polysaccharides can limit the utilization of nutrients in animal feed. Breaking down these components with xylanase can help improve nutrient availability, making xylan management an important consideration when formulating swine and poultry diets.

Why Xylanase Thermostability Matters in Feed Processing

Feed conditioning and pelleting can expose enzymes to high temperatures that may reduce xylanase activity before the feed reaches the animal. Xygest HT is intrinsically thermostable, helping maintain xylanase activity through high-temperature processing so the enzyme can remain effective in the finished feed.

Performance Evidence in Broiler Diets

In a broiler study, diets supplemented with Xygest™ HT 20D resulted in significantly higher body weight gain and lower feed conversion ratio compared with the negative control diet, which contained 100 kcal/kg less AME and 2% less digestible amino acids.
