BIOLOGICAL SOLUTIONS OF FEED PROCESSING
ANIMAL FEED ENZYMES
Enzymes are organic substances with high biological value and they are of a great importance for the
normal performance of the basic metabolic processes in the living organism. In the digestive system of the
animals, feed enzymes help the dissociation of the main nutritive substances coming with the feed to
constituents that easily pass through the small intestine wall and become assimilated by the animals.
The digestive processes in the animals body perform and depend completely on the action of the
endogenous hydrolysing enzymes.
Besides the basic nutritive substance, the feed contains also cellulose, hemicellulose, pectin substancies, β-
glucans, oligosaccharides and others, which can not be digested by poultry and piglets because of lack of
Moreover the above mentioned substances (known as non-starch polysaccharides) are not utilized, some of
them form viscose mass in the alimentary tract, which prevent the enzymes digestion and complete
utilization of the rest nutritive substances.
Significant achievement in the field of feed enzymes is the creation of stabilized polyenzyme products that
are combination of several enzymes, making them more effective due to the synergic effect of the different
