title: Hereditary dwarfism in pigs.
abstract: In a swine production herd dwarfs with extremely short limbs were observed in 3 litters sired by the same boar. Clinical, radiographical, and pathologic-anatomical examinations, showed the affected individuals to be chondrodysplastic dwarfs. Such dwarfism has not been reported previously in pigs. An inbreeding experiment conducted with a dwarf gilt and related boars indicated that the dwarfism was hereditary with a simple autosomal recessive inheritance.
