Total bacterial DNA was extracted from foremilk samples and swab samples of the teat canal.

Machine milk, foremilk, and stripping milk fractions in udders where both halves were healthy were compared.

The electrical conductivity values for the machine milk were intermediate and significantly different from conductivity of foremilk and stripping fractions.

Significant differences were observed in the SCC and electrical conductivity, but not in California mastitis test, between foremilk and stripping milk.

The log SCC of the machine milk did not differ from that of the foremilk fraction but was significantly less than the stripping milk.

Foremilk and hand stripping milks were taken from each individual teat; machine milk was taken from the entire udder.
