Abstract
An enzyme feed additive is provided comprising a xylanase, a protease, and optionally a .beta.-glucanase. The ratio of the units of xylanase activity per unit amount of the feed additive to the units of .beta.-glucanase activity per same unit amount of the feed additive is 1:0-0.25. Preferably, the xylanase is the low pI xylanase and/or the high pI xylanase obtained from Trichoderma longibrachiatum. Preferably, the protease is a mutant subtilisin comprising a substitution at the amino acid residue position equivalent to tyr+217 of Bacillus amyloliquefaciens subtilisin with leucine.
