[QUOTE="J Hoy, post: 1687916, member: 16398"] While often blamed on bad genes, these types of birth defects can be caused by mineral deficiencies during fetal development. It is too bad the dog chewed the front of the face off, which is fairly common with canines that find dead newborn grazing animals. It would have been interesting to see if the calf had underdeveloped facial bones in addition to the skeletal and limb malformations. It likely also had an enlarged right ventricle of the heart and underdeveloped thymus. The calf was either born dead or died soon after it was born. Newborn mammals with such extensive birth defects do not live long after they are born, if they are born alive. I have necropsied deer, calves and domestic goats with similar leg malformations, but only one deer fawn had similar spinal malformations in addition to the crooked legs. All had underdeveloped upper facial bones and an underbite. I never considered such malformations to be caused by the genes of the parents, since it happened in multiple species. [/QUOTE]
