Abstract

A method of supplying a ruminant with its nutritional requirements for methionine is provided wherein an ester of 2-hydroxy-4(methylthio)butanoic acid that is available for absorption by a ruminant is administered to the ruminant. Preferably, the ruminant is administered an ester of 2-hydroxy-4(methylthio)butanoic acid is selected from the group consisting of methyl, ethyl, butyl, and 3-methylbutyl, and salts thereof.

Claims

exact text as granted — not AI-modified
1 . A method of supplying a hydroxy analogue of methionine that is available for absorption to a dairy cow, comprising administering to the cow an ester of 2-hydroxy-4(methylthio)butanoic acid, wherein the ester is selected from the group consisting of methyl, ethyl, butyl, and 3-methylbutyl, and salts thereof.  
     
     
         2 . The method of  claim 1 , wherein the ester of 2-hydroxy-4(methylthio)butanoic acid comprises the methyl ester of 2-hydroxy-4(methylthio)butanoic acid.  
     
     
         3 . The method of  claim 1 , wherein the ester of 2-hydroxy-4(methylthio)butanoic acid comprises the ethyl ester of 2-hydroxy-4(methylthio)butanoic acid.  
     
     
         4 . The method of  claim 1 , wherein the ester of 2-hydroxy-4(methylthio)butanoic acid comprises the butyl ester of 2-hydroxy-4(methylthio)butanoic acid.  
     
     
         5 . The method of  claim 1 , wherein the ester of 2-hydroxy-4(methylthio)butanoic acid comprises the 3-methylbutyl ester of 2-hydroxy-4(methylthio)butanoic acid.  
     
     
         6 . The method of  claim 1 , wherein at least 20% of the ester of the 2-hydroxy-4(methylthio)butanoic acid is available for absorption by the cow.  
     
     
         7 . The method of  claim 1 , wherein at least 40% of the ester of the 2-hydroxy-4(methylthio)butanoic acid is available for absorption by the cow.  
     
     
         8 . The method of  claim 1 , wherein between about 40% and about 55% of the ester of the 2-hydroxy-4(methylthio)butanoic acid is available for absorption by the cow.  
     
     
         9 . The method of  claim 1 , wherein the ester of 2-hydroxy-4(methylthio)butanoic acid is administered to the cow by feeding the cow a feed comprising the ester of 2-hydroxy-4(methylthio)butanoic acid.  
     
     
         10 . The method of  claim 9 , wherein the feed is a ruminant feed ration.  
     
     
         11 . The method of  claim 10 , wherein the feed ration comprises a grain portion.  
     
     
         12 . The method of  claim 10 , wherein the feed ration comprises a forage portion.  
     
     
         13 . The method of  claim 12 , wherein the forage portion is selected from haylage and silage.  
     
     
         14 . A method of improving milk, the method comprising administering to a dairy cow an ester of 2-hydroxy-4(methylthio)butanoic acid, wherein the ester is selected from the group consisting of methyl, ethyl, butyl, and 3-methylbutyl, and salts thereof.  
     
     
         15 . The method of  claim 14 , wherein the milk improvement comprises increased milk protein content.  
     
     
         16 . The method of  claim 14 , wherein the milk improvement comprises increased milk fat content.  
     
     
         17 . The method of  claim 14 , wherein the milk improvement comprises increased milk volume.  
     
     
         18 . The method of  claim 14  wherein at least 20% of the ester of the 2-hydroxy-4(methylthio)butanoic acid is available for absorption by the cow.  
     
     
         19 . The method of  claim 14  wherein at least 40% of the ester of the 2-hydroxy-4(methylthio)butanoic acid is available for absorption by the cow.  
     
     
         20 . The method of  claim 14  wherein between about 40% and about 55% of the ester of the 2-hydroxy-4(methylthio) butanoic acid is available for absorption by the cow.  
     
     
         21 . A ruminant feed ration comprising: 
 a plurality of natural or synthetic feed ingredients which comprises one or more grains; and    an ester of 2-hydroxy-4(methylthio)butanoic acid;    wherein the ester is selected from the group consisting of methyl, ethyl, butyl, and 3-methylbutyl, and salts thereof.    
     
     
         22 . The ruminant feed ration of  claim 21 , wherein the feed ingredients further comprise a forage portion.  
     
     
         23 . The ruminant feed ration of  claim 21 , wherein the forage portion is selected from haylage and silage.
