Udders and teats conformation changes that undergo in subsequent lactations were analysed with regard to mastitis. The studies included 97 Black-and-White and Red-and-White cows managed in a herd of an average annual yield of 10,000 kg of milk, in one of the leading specialist farms located in south-west Poland. First lactation cows are characterised by relatively low somatic cell counts in milk, lower than multiparous cows.
