Biuret is an exclusive, cost-effective, controlled-release, non-protein nitrogen (NPN) source for ruminants. Biuret’s predictable and safe rumen ammonia release pattern allows for greater formulation flexibility for both beef and dairy rations. Biuret is not hygroscopic and is superior to urea-based products for all applications where supplemental NPN is required, including free-choice minerals, blocks and tubs, range cubes, conventional rations and liquid feed applications. The unique nature of biuret makes it easy to include in ruminant diets while lowering cost of production.
