[Incidence of udder infection in bovine primiparae and milking order (author's transl)].
On four farms taking part in a mastitis prevention programme, milking primiparous animals first failed to result in a significant decrease of the level of udder infection during the first half of lactation. This result may nevertheless be regarded as positive, as there was a rise in infection level among the older animals of the experimental group and a decline in the controls at the same time.
