Optimizing Animal Nutrition

BRI specializes in the research, development and manufacture of unique enzyme feed additives that improve animal nutrition and growth. Our products have set the standard for consistent premium quality and performance around the world. BRI’s first enzyme, Versazyme has become the most widely used protease enzyme on the market.

The interest in and use of enzyme feed additives is growing rapidly as more producers become familiar with the positive effects that enzymes have on animal nutrition, and the management of rising costs and feed grain quality variability. Enzymes can also be used to safely promote animal growth, and may offer a natural alternative to antibiotic growth promoters.

Found in all living cells, enzymes catalyze chemical processes that convert nutrients into energy and animal and plant tissue. In the case of animal nutrition, enzymes bind to specific substrates in the animal feed which then break down into smaller components. Each type of enzyme is highly efficient in its activity on specific substrates, requiring only a small quantity to produce the desired effect. However, enzymes that occur naturally within an animal are sometimes unable to effectively break down feed grains to release all of the available nutrients to the animal. We create enzyme feed additives that supplement the animal’s own enzymes, leading to improved nutrition and gut health. The primary types of enzymes used in poultry and swine production include carbohydrases, phytases and proteases.

Quality Assurance

BRI enzyme feed additives are designed, developed and tested in the USA, and manufacturing takes place in the U.S. and overseas under strictly controlled conditions to ensure consistent quality and safety. Our manufacturing processes comply with leading global standards including GMP and FAMI-QS.
