KEMZYME® Protease

The Role of Single Enzyme, Kemzyme® Protease in Livestock Feed Digestion.

In order to increase the digestibility of proteins in livestock feed, the use of exogenous proteases in feed is gaining importance. Proteases are naturally produced and present in the gastrointestinal tract of animals but several studies on crude protein and amino acid digestibility have revealed that up to 20% of crude protein / amino acids are excreted without being completely digested. This portion of undigested protein represents an opportunity for supplementation of exogenous proteases in animal feeds to improve protein digestibility. 

KEMZYME® Protease, a novel coated multi-protease from Kemin (U.S. Patent 12/100,085), is a blend of thermostable acid, alkaline and neutral proteases, which improves the protein digestion at the various pH levels of the gastrointestinal tract (GIT), thus improving protein and amino acid digestibility. It is engineered to release proteases at different sites of the intestine thereby enabling protein digestion with extended action in the GIT.


Benefits of KEMZYME® Protease:

  • Improves protein digestion and utilisation for improved weight gain, improved feed efficiency and improved economic efficiency.
  • Degrades proteinaceous anti-nutrients such as protease inhibitors, which may otherwise cause reduced nutrient digestibility or even induce pathological changes in the intestine and liver tissues.
  • Supports a healthy gastrointestinal tract by improving protein digestion thereby reducing the level of undigested proteins in the hindgut.  Excess protein is a fermentation substrate that may cause an increase in the population of harmful bacteria in the hind gut such as Clostridium perfringens, which negatively affects nutrient utilisation.
  • Reduces nitrogen emissions during livestock production due to improved protein digestion and utilisation.
