RESUMO
Mummification of bovine fetuses is an uncommon condition, and cows do not always respond to treatment with prostaglandin F2alpha. The objective of the present retrospective and descriptive case study was to determine the conception rate and survival time of nonresponsive, prostaglandin F2alpha (PGF2alpha)-treated cows (n = 14), following hysterotomy or medical treatment and manual removal. Animal records from 1990 to 2005 from the Centre Hospitalier Universitaire Vétérinaire (CHUV) of the Université de Montréal were studied. Inclusion criteria were the nonexpulsion of the mummified fetus following PF2alpha treatment and absence of concomitant conditions upon physical examination. Of the animals included in the study, 36% (n = 5) became pregnant after extraction of the mummified fetus by hysterotomy and 0% conceived after medical treatment and manual extraction. In this study, hysterotomy represented an effective approach for extracting mummified fetuses from cows that did not respond to PF2alpha treatment.
