Patent ID: 7851147

Claim:
A method of determining relative levels of saturated fatty acids and unsaturated fatty acids in bovine milk obtained from one or more cows: (a) testing genetic material of the one or more cows for the presence of DNA encoding β-casein having a proline residue at position 67 or DNA encoding β-casein having a histidine residue at position 67; (b) identifying whether a cow or cows (i) will likely have a lower percentage of saturated fatty acids and a higher percentage of unsaturated fatty acids based on being homozygous for DNA encoding β-casein having a proline residue at position 67 or (ii) will likely have a higher percentage of saturated fatty acids and a lower percentage of unsaturated fatty acids based on being homozygous for the DNA encoding β-casein having a histidine residue at position 67 for which genetic material was tested in (a); and (c) obtaining milk from at least one of the one or more cows after step (b).
