[A survey of mastitis control, based on the number of drug containers made commercially available in the Netherlands during the period from 1971 to 1977 (author's transl)].

The figures on the number of marketed short-acting and long-acting antibiotics for the control of mastitis reported by the industry convey an impression of the mastitis situation in the Netherlands. The numbers and proportions of quarters and animals treated with short-acting antibiotics as well as the number and proportions of dry cows are reviewed. The figures suggest that the number of animals treated for acute mastitis are gradually decreasing, whereas the number of cattle treated with long-acting antibiotics in the early part of the dry period continues to be fairly constant.
