Alltech's non-protein nitrogen (NPN) source for ruminants.

Optigen has become a solution to feed and environmental problems. It concentrates the nitrogen fraction of the diet, creating dry matter space for more fibre and energy.

Available in 25kg bags.

Alltech’s non-protein nitrogen (NPN) source for ruminants, concentrates the nitrogen fraction of the diet, creating dry matter space for more fibre 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 

Optigen 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 novel ingredient that can help nutritionists make improvements in ruminant diets
  • Supports microbial synthesis resulting in the support of rumen health and fermentation
  • Sustained release of non-protein nitrogen
  • Allows the opportunity to formulate cheaper feed ingredients and lower the cost of rations
  • Creates 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

Testimonial / Case Study

“Over the last number of months, we have seen many supply chain issues affecting the availability of raw materials — protein sources in particular. Soybean meal remains the go-to protein source in ruminant diets and one that many farmers, both beef and dairy, heavily rely on. While the supply of soybean meal has come under challenge in recent times, which is reflected in its price, there also remains a growing global concern around the environmental impact associated with its use in ruminant diets.”


“This leaves us with the question: Is there a more environmentally friendly and cost-effective solution to replacing soybean meal in ruminant diets?”
