Contagious Abortion of Cows

The opening pages introduce a concise yet thorough investigation into a disease that has plagued cattle producers for generations. Drawing on decades of observation and the latest laboratory work of the early 1900s, the authors explain how a specific bacterium, first identified by Danish researchers, is responsible for the sudden loss of unborn calves. Their narrative balances careful scientific detail with clear explanations, making the material accessible to both veterinarians and the farm families who rely on healthy herds.

Beyond the historical backdrop, the bulletin offers practical, step‑by‑step recommendations for controlling the infection. It describes how to isolate affected cows, the routine cleaning of genital tracts with antiseptic solutions, and the safe disposal of contaminated material. Guidance on disinfecting stalls and managing breeding bulls rounds out a hands‑on guide aimed at preserving livestock productivity.

Readers will come away with a solid understanding of the disease’s origins, its visible signs, and the early 20th‑century methods devised to halt its spread—knowledge that still echoes in modern herd‑health practices.
