Claim 22:
23. A method for identifying an animal or animals having preclinical or clinical mastitis from at least 100 individual animals contributing milk to a volume of milk, the method comprising the steps of:
a′) determining the proportion or quantity of DNA contributed by the individual animals to the volume of milk by a method comprising allele sampling of a plurality of DNA sequence polymorphisms in DNA extracted from a sample of the volume of milk by SWGS, wherein the sequencing depth is 10 or less and wherein the plurality of DNA sequence polymorphisms comprises at least 1×105 DNA sequence polymorphisms;
b′) determining the concentration of somatic cells in the milk of the individual animals, based on the proportion or quantity of DNA contributed by the individual animals to the volume of milk as determined in step a′); and
c′) identifying an animal or animals as having preclinical or clinical mastitis when the concentration of somatic cells in the milk of said animal or animals as determined in step b′) exceeds a predetermined threshold.
