The book begins with a general chapter on the approach to an abortion, followed by species-specific chapters. Each chapter begins by outlining the pathogenesis of abortion and neonatal loss, then moves on to special diagnostic techniques, fetal and placental anatomy and physiology, and detailed descriptions of the various causes of abortion or neonatal loss.  A companion website offers the images for download at www.wiley.com/go/njaa.  Kirkbride's Diagnosis of Abortion and Neonatal Loss in Animals, Fourth Edition is a useful guide for veterinary practitioners, diagnosticians, pathologists, theriogenologists, students, and technicians.
