Optigen® is Alltech's non-protein nitrogen (NPN) source for ruminants. It concentrates the nitrogen fraction of the diet, creating dry matter space for more fiber and energy. After being launched only a few years ago, Optigen has become a solution to feed and environmental problems.

• Reformulations with Optigen can be used to provide:

  • Available nitrogen for fiber-digesting bacteria over time
  • Fermentable carbohydrate for sustaining higher milk yields
  • Microbial protein synthesis as a result of more efficient ruminal function
  • Effective fiber for sustaining a healthy rumen
  • Control over dietary heat increment in the summer

• Is a technology that enables you to reformulate more rumen-friendly diets, which result in:

  • Microbial proteins
  • Fiber digestion
  • Efficiency of rumen nitrogen capture

• This technology helps to provide sustained availability of ammonia in the rumen environment ensuring that the rumen bacteria have continued access to this essential food source.

- Works to create an environment for:

  • Optimizing ruminal nitrogen metabolism
  • Nutrient synchronization
  • Microbial efficiency


  • Is a superior non-protein nitrogen source for ruminant nutrition.
  • Is a source of non-protein nitrogen.
  • Is a novel ingredient that can help nutritionists make improvements in ruminant diets.
  • The quality control system behind Optigen provides a consistent product from batch to batch and traceability from start to finish.
  • Supports microbial synthesis resulting in the support of rumen health and fermentation.
  • Allows the opportunity to formulate cheaper feed ingredients and lower the cost of rations.
  • Sustained release of non-protein nitrogen
  • Similar nitrogen release rate to that of soybean meal
  • Unique ingredient for ruminants
  • Works to create an environment for optimizing ruminal nitrogen metabolism, nutrient synchronization and microbial efficiency.
  • Is designed to provide a safe, concentrated source of ruminally degradable protein activity of ruminal bacteria populations.
