Morphological differences in size and shape of long bones have been reported between double muscled and normal cattle. Wrist (1929) found limp bones of double-muscled cattle to be shorter and of decreased density. Vissac (1968) reported that shafts of lone bones of double muscled cattle were more slender but had larger epiphyses. Hendricks et al.(1973) reported lighter and shorter bones that had thinner cortices in double muscled muscled cattle.
