Exogenous proteases are becoming more popular in livestock feed to increase the digestibility of proteins. Animals naturally produce proteases in their digestive system. However, young animals have immature digestive systems and cannot produce a sufficient amount of endogenous enzymes necessary to handle the large concentration of protein in their diet. Studies have also revealed that about 20% of crude protein and amino acids are excreted before they are completely digested.
The undigested proteins have been shown to favour the proliferation of pathogens such as Clostridium perfringens as it builds up in the lower portion of the intestinal tract and acts as a substrate for the bacteria. High protein concentrations will also lead to increased uric acid in the excreta, which is linked to higher litter moisture, and, consequently, hock, feet and breast lesions. Therefore, supplementing exogenous proteases to improve protein digestion in animal feed is necessary to maximize protein digestion.
Fullzyme® PRO is active throughout the digestive tract, with a pH range adapted to the bird physiology, which means it can cleave peptides almost anywhere. This helps complement the animal's endogenous proteases and ensures that valuable amino acids are available for muscle building and growth.
