| abstract |
The present invention relates to the use of bacterial amylases in feed for bovine animals, in particular to the use of at least one bacterial amylase in feed for ruminants of the subfamily Bovis, in particular for improving milk production, apparent digestion of the fed diet rate, disappearance of feed dry matter, body weight gain, and/or feed conversion ratio (FCR). Examples of bovine animals are dairy and beef cattle. The present invention also relates to the use of these amylases in feed and feed additives such as premixes, concentrates and total mixed rations (TMR). Amylases may be used in combination with cellulases to improve milk yield and/or backfat thickness. Preferred amylases are derived from Bacillus halmapalus, Bacillus licheniformis and Bacillus stearothermophilus, and are preferably homologous to the Bacillus stearothermophilus amylase. |
