In rats of 40, 49 and 59 days of age the positions of the femoral and tibial nutrient foramina were determined by direct measurement, using a travelling microscope. The femoral nutrient foramen remained constant in position with increasing age, whereas the tibial nutrient foramen moved relatively nearer to the distal end of the shaft. In the case of the femur this can be accounted for entirely by differences in growth rates at the epiphyseal plates of the femur compensating for the disproportion in the distances of the foramen from the two plates. In the tibia, however, extension of the extremely oblique nutrient canal as the bone increases in girth is also involved. Bone remodelling in the vicinity of the canal is not necessary to explain the results.
在40日龄、49日龄和59日龄的大鼠中，使用移动显微镜通过直接测量来确定股骨和胫骨滋养孔的位置。随着年龄增长，股骨滋养孔的位置保持不变，而胫骨滋养孔相对地向骨干远端移动。就股骨而言，这完全可以通过股骨骨骺板生长速率的差异来解释，这种差异弥补了滋养孔到两块骨骺板距离的不均衡。然而，在胫骨中，随着骨骼周长增加，极倾斜的滋养管的延伸也起到了作用。无需用骨管附近的骨重塑来解释这些结果。
