PROBLEM TO BE SOLVED: To obtain a feed composition fully retaining enzyme activity even after undergoing a process with a heating-type equipment, fortified in its functionality and nutritive value and excellent in storability and digestibility in the body of livestock by including a heat-resistant enzyme having a specified residual activity of at least a specific value. SOLUTION: This feed composition is obtained by including at least one heat-resistant enzyme having a residual activity of >= 60% when heated at 80 deg.C for 20s and selected from cellulase, xylanase, protease, lipase and amylase. It is preferable that the heat-resistant enzyme is an enzyme obtainable from e.g. Bacillus sp.SD401(FERM P-11527), SD402(FERM BP-3431), SD403(FERM P-11647), SD771(FERM P-11455), SD772(FERM P-11456), SD902(FERM BP-4508), NKS-21(FERM BP-3911), and also the feed composition is produced by addition of the heat-resistant enzyme followed by heating with a heating-type equipment at >= 70 deg.C. |
