Abstract
FIELD: veterinary medicine.
SUBSTANCE: proposed method for increasing starch digestibility and glucose yield in a ruminant animal includes the addition of at least one alpha-1,4/1,6-glycoside hydrolase (GLCH) selected from α-amylase from an Aspergillus kawachii (AkAA) source and α-amylase from an Aspergillus Clavatus (AcAA) source as a feed additive in ruminant animal feed. The specified hydrolase (a) is characterized by at least 20% activity at a pH value of 3 or less in the presence of pepsin compared to hydrolase activity at a pH value of 6 in the presence of pepsin; (b) the specified hydrolase is active in at least two of three digestive chambers of the ruminant animal, including the rumen, rennet and small intestine; (c) hydrolase acts together with digestive enzymes present in digestive chambers of the ruminant animal to increase the digestibility of starch and glucose yield. A method for an increase in starch digestibility, increase in glucose yield, increase in the digestion of dry substance and increase in gas formation during fermentation in a ruminant animal is also proposed by adding an enzyme-based composition containing the specified hydrolase and at least one protease selected from pepsin, pancreatin, bacillolysin (P7L) and thermolysin (P14L) to the feed.
EFFECT: invention is aimed at increasing the digestibility of starch and glucose yield.
