Inheritance of limber legs in Jersey cattle

Pedigree information from 105 cases of limber leg Jersey calves indicate that this semilethal abnormality is inherited as a simple autosomal recessive. The increased incidence of this abnormality in recent years suggests a rise in the gene frequency, probably due to the popularity and widespread use of a carrier bull Favorite Commando, his daughter Marlu Milady, and many of their descendants. Steps to control this abnormality have been taken by the American Jersey Cattle Club.
