Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
132 words
A method of improving the milk production of dairy cows, which comprises feeding to said cows as part of their feed diet a composition or complex of 2-hydroxy-4-(methylthio) butyric acid methionine hydroxy analog and a fungal enzyme derived from a microorganism of the genus Aspergillus, the methionine hydroxy analog being present in an amount of 5-20% by weight of the composition and being in particulate form, with the particles thereof being coated with a powder of synthetic flavoring agent which masks the taste of the methionine and fungal enzyme being present in an amount of 0.5-5% by weight of the composition and a buffer in the amount of 2-6% by weight, the composition or complex being fed in an amount to provide 20-40 g./day of the methionine hydroxy analog to each cow.
Claim 2
Independent Claim
132 words
A method of improving the milk production of dairy cows, which comprises feeding to said cows as part of their feed diet a composition or complex of 2-hydroxy-4-(methylthio) butyric acid methionine hydroxy analog and a fungal enzyme derived from a microorganism of the genus Aspergillus, the methionine hydroxy analog being present in an amount of 5-20% by weight of the composition and being in particulate form, with the particles thereof being coated with a powder of synthetic flavoring agent which masks the taste of the methionine and fungal enzyme being present in an amount of 0.5-5% by weight of the composition and a buffer in the amount of 2-6% by weight, the composition or complex being fed in an amount to provide 20-40 g./day of the methionine hydroxy analog to each cow.
