Özet

Milk and disease records were used from 1275 lactations of British Friesian cows, belonging to Sonning farm of Reading University, resulting from calvings that occurred between 1984 and 1989. Eight hundred and forty pairs of successive lactations were available from the total lactation recorded. These were used to consider the relationship between the occurrence of clinical mastitis and changes in milk yield, and to develop a statistical technique that enables the estimation of changes between successive lactations associated with clinical mastitis.
