De structuur van de substantia compacta van de metatarsus in verband met de calcium- en fosforhuishouding bij rundvee
1956
van der Wal, P.
In 15 cattle aged from one day to fifteen years the structure and development of the metatarsus, especially compact bone, was studied. For this purpose the metatarsus was divided into 20 slices of equal thickness. The structure, growth and the reconstruction of the metatarsus were discussed.Next the relation between the calcium and phosphorus balance of cattle and the structure of the metatarsus was studied in material from 64 bulls and 327 cows. The influence was examined of age, date of calving, number of lactations, milk production, stalling period, type of soil and tuberculosis on the structure of the metatarsus.The structure of compact bone of the metatarsus of cattle was influenced by the calcium and phosphorus balance. From the microscopic structure of the metatarsus conclusions could be drawn about the adequacy of the supply of minerals. The large individual variations in bone structure made it likely, that other factors are also important.
