Contagious Abortion of Cows

"Contagious Abortion of Cows" by Ward J. MacNeal is a bulletin that tackles a major problem in early 20th-century farming: contagious abortion in cows. Created with Herbert W. Mumford and released by the University of Illinois Agricultural Experiment Station, this book digs into the science behind the disease, which caused huge financial losses for cattle farmers. MacNeal looks at the history of research into the disease and shines a light on the specific germ that causes it, explaining how it spreads and what farmers can do to stop it. The book includes findings from studies proving how easily the disease jumps from cow to cow. MacNeal gives hands-on advice for spotting, treating, and wiping out the disease in herds, including keeping sick animals away from healthy ones, cleaning up infected areas, and carefully managing how cows breed. The book's main goal is to help farmers and vets get a grip on this tough agricultural problem and find ways to deal with it effectively.
