Breeding Soundness Examinations of Rams and Bucks

By Dr. Allen Bridges, Dr. Mike Neary, Lynn Pezzanite, Terry Hutchens

For optimal farm productivity, producers should select rams or bucks that have the ability to settle a large portion of females early in the breeding season and sire offspring with the genetic potential for rapid, efficient growth. To help identify males that are capable or not capable of settling females, producers can perform breeding soundness examinations (BSEs). Up to 10 to 15 percent of rams and bucks are of unsatisfactory reproductive breeding quality. Utilizing a BSE to identify fertile males and eliminate males with sub-par
(or inferior) fertility prior to the breeding season can improve economic returns to a flock or herd.

Caprine Arthritis Encephalitis in Goats: A Devastating Disease

By Mikelle Roeder

Caprine arthritis-encephalitis (CAE) is now considered one of the most significant diseases affecting the goat industry in the United States. It is caused by a lentivirus, a type of retrovirus, which is a family of pathogens responsible for many immunodeficiency diseases in many species, and most breeds of goats are susceptible. CAE causes multiple diseases in goats: arthritis, pneumonia, mastitis and weight loss in adults, and encephalitis (inflammation of the brain and brain stem) in kids.
