The vascular morphology of the proximal femur, tibiotarsus and tarsometatarsus was studied in growing broiler chicks. A carousel was used to exercise one group of 24 birds for four periods of 15 minutes each day. A second group (controls) were not exercised. Some birds were killed during the course of the experiment, and the remainder after 25 days of exercise when they were 33 days old. After killing the limbs were perfused and the bone extremities cleared. The bone extremities were then cut into 1 mm thick slabs and examined. There were abnormalities of the physis and physeal vasculature in 18 (25 per cent) of the bone extremities from the exercised birds and in 24 (40 per cent) of the bone extremities from the unexercised (control) birds. The low level of activity in the unexercised fowls of the present study appeared to contribute to these abnormalities.
对生长中的肉鸡雏鸡的股骨近端、胫跗骨和跗跖骨的血管形态进行了研究。使用一个旋转木马装置让一组24只鸡每天进行4次，每次15分钟的运动。第二组（对照组）不进行运动。在实验过程中处死了一些鸡，其余的在运动25天后，即33日龄时处死。处死后对肢体进行灌注，并清理骨末端。然后将骨末端切成1毫米厚的薄片进行检查。运动组鸡的骨末端中有18个（25%）出现了生长板和生长板血管异常，未运动（对照）组鸡的骨末端中有24个（40%）出现了异常。本研究中未运动家禽的低活动水平似乎导致了这些异常。
