title: [Continuing eco-pathological survey: 7. Epidemiological approach to postpartum mastitis in the dairy cow: descriptive study and typology of the herd].
abstract: In this study, post-partum mastitis are considered as an epidemiological entity because of their high frequency (20% of cases of mastitis are observed in the seven first days after calving). The rate increases in May-June-July and after the fourth calving. Characteristics of herds with high frequency of post-partum mastitis are the same that those from herds with high frequency of mastitis or metritis, their risk factors seeming to exert an effect on all infectious diseases. Among these factors, straw bedding quantity seems to be the more important one: a low quantity of straw, even in herds where prophylaxis against mastitis is largely used (teat dipping, dry cow therapy, disinfection), is a favouring factor for apparition of mastitis just after calving. On the contrary, use of individual towels, an abrupt dry cow therapy and a vitamin prevention during the last part of pregnancy, appear more favorable.
