Osteopenia as a result of copper deficiency in a dwarf Thuringian Forest goat

In a female Thuringian forest goat osteoporosis, dwarfism and anaemia were found. The animal was kept on a hobby farm with 30 further goats that did not show clinical signs. Radiological examination, computed tomographic imaging and pathological examination revealed reduced bone density and numerous fractures associated with limited or completely absent callus formation. Incineration of selected bones did not show any differences concerning the contents of calcium and phosphorus when compared to two control goats. Therefore, a regular mineralisation of the bone matrix was indicated. The dysfunction associated with the osteogenesis was assumed to be a copper deficiency.
