Abstract

In studies of bovine mastitis, it has been repeatedly confirmed that milking is associated with entrance of microorganisms into the mammary gland (International Dairy Federation, 1987; Bramley, 1992). As different husbandry practices apply between cattle and dairy sheep (cows are machine milked, ewes are usually hand milked), results from cows may not always apply to ewes. The objective of this investigation was to determine whether there were differences in bacterial flora populations in the teat duct and mammary secretion of ewes before and after milking.
