  • Publication number: 20210299229
    Abstract: Disclosed are uses at least one alpha-1,4/1,6-glycoside hydrolase (GLCH) as a feed additive for a ruminant wherein said hydrolase: (a) has at least 20% activity at pH less than or equal to 3 in the presence of pepsin as compared to activity of the hydrolase at pH 6 in the presence of pepsin, (b) said hydrolase is active in at least two of three digestive chambers of a ruminant comprising a rumen, an abomasum and a small intestine and (c) the hydrolase works with pancreatic amylase to increase glucose yield.
