[Ca and P supply of ruminants in the 19th and beginning of 20th century in Middle Europe].
The present review evaluates veterinary publications about some bone diseases in ruminants till 1925. According to more than 100 publications in some regions of Germany as well as in Scandinavian and Westeuropean countries during the 19th century several cases of bone fractures in ruminants were reported, mainly in pregnant and lactating cattle and goats. From a recent point of view and after feed analyses this disease obviously was caused by a P-deficiency. Bone fractures sometimes were accompanied by licking behaviour, but in other regions pica (without severe skeletal deformations) was probably related to a Cu- or Co-deficiency. Swelling of the jaws (probably by Ca-deficiency) was exclusively described in goats. By preventive measures (feeding bone meal, P-fertilisation) bone fractures diminished in the beginning of the 20th century. After the experience in the past in ruminants bone diseases may come back, if effective preventive measures will be ignored due to the recent trends towards 'natural farming'.
