Description
Scapular displacement due to bilateral rupture of the serratus ventralis muscles ("flying scapula") occurred in four heifers from a large beef herd. Two of the four affected animals were necropsied. Additional animals on the farm developed intermittent lameness when enclosed on certain pastures. The lameness and scapular displacement were attributed to selenium deficiency in the feed and pasture environment. This is the first account of "flying scapula" in the United States
