Brachygnathia in a herd of Angus cattle.
Seven cases of brachygnathia in a single calf crop (28 calves) were observed in an Angus herd. Two of the affected calves, 1 female and 1 male, were necropsied and anatomically described. Breeding histories and results of pedigree analysis involving the 7 affected calves indicated the cause of the defect to be genetic with the mode of inheritance that of a single autosomal recessive gene.
