You never know when they are going to show up and they are very rarely welcome visitors. I’m Jeff Keane; I’ll be back after this quick break to explain who they are.

Worse than any unwanted houseguest, detrimental genetic disorders in livestock can cause unneeded stress and economic losses to producers. I can remember the dwarf calves that caused so many problems to cattle breeders in the 1950’s and early 1960’s. Horse and sheep genetic maladies have also created economic issues and heartache. Late in 2008, a new genetic problem was announced to cattle producers -- Arthrogryposis Multiplex or AM. The disease has so far only been exhibited in Angus cattle and is also known as Curly Calf Syndrome. This lethal genetic defect causes calves to be stillborn, smaller than normal with twisted or bent spines, and many times rigid hind legs. The condition was first noticed with the spring 2007 calf crop. The good news is the American Angus Association working with Nebraskan veterinarian, David Steffen, University of Illinois animal science professor, Jonathan Beever, and concerned producers traced the problem to a genetic disorder and developed a test to identify carrier animals. To the credit of one of the prominent producers affected, Gradiner Angus Ranch, they met the problem head on and in the public light. I believe, with such quick response and cooperation this potentially devastating disease will be eliminated in a timely manner and Angus breeders will move forward again. I’m Jeff Keane.
