Abstract
Official abstract text for this publication.
The present invention relates to methods and uses of at least one bacterial amylase in poultry feed to improve the nutritional value of the feed. The invention also relates to poultry feed and poultry feed additives comprising at least one bacterial amylase and at least one vitamin and/or mineral which improve the nutritional value of the feed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for improving weight gain and/or feed conversion ratio of poultry, comprising feeding the poultry with a feed which comprises at least one alpha-amylase in an amount of between 20 and 400 KNU/kg feed, wherein the alpha-amylase is a polypeptide having at least 95% identity to amino acids 1-481 of SEQ ID NO: 2 and the alpha-amylase improves weight gain and/or feed conversion ratio of poultry. 2. The method of claim 1 , wherein the alpha-amylase has at least 96% identity to amino acids 1-481 of SEQ ID NO: 2. 3. The method of claim 1 , wherein the alpha-amylase has at least 97% identity to amino acids 1-481 of SEQ ID NO: 2. 4. The method of claim 1 , wherein the alpha-amylase has at least 98% identity to amino acids 1-481 of SEQ ID NO: 2. 5. The method of claim 1 , wherein the alpha-amylase has at least 99% identity to amino acids 1-481 of SEQ ID NO: 2. 6. The method of claim 1 , wherein the alpha-amylase comprises amino acids 1-481 of SEQ ID NO: 2. 7. The method of claim 1 , wherein the poultry feed has reduced apparent metabolisable energy compared to the poultry feed without the alpha-amylase. 8. The method of claim 1 , wherein the alpha-amylase is added to the poultry feed at a dose of between 0.01 and 200 mg enzyme protein per kg diet.
