Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
61 words
A method of improving the milk production of dairy cows which comprises feeding to said cows as part of their diet a feed supplement containing an amount effective to improve milk production of γ-methylmercapto-α-hydroxybutyric acid and its oligomers, which oligomers are about 10 to 75% of the total equivalent free γ-methylmercapto-α-hydroxybutyric acid in said amount of the acid and its oligomers.
Claim 2
Independent Claim
61 words
A method of improving the milk production of dairy cows which comprises feeding to said cows as part of their diet a feed supplement containing an amount effective to improve milk production of γ-methylmercapto-α-hydroxybutyric acid and its oligomers, which oligomers are about 10 to 75% of the total equivalent free γ-methylmercapto-α-hydroxybutyric acid in said amount of the acid and its oligomers.
Claim 3
Dependent Claim
29 words
The method of claim 1 where the oligomers are about 20 to 60% of the total equivalent free -methylmercapto-α-hydroxybutyric acid in said amount of the acid and its oligomers.
Claim 4
Independent Claim
29 words
The method of either claims 1 or 2 where the effective amount of γ-methylmercapto-α-hydroxybutyric acid as free acid equivalent is about 20 to 40 grams per day per cow.
