Broiler fowls were reared from hatching till 20 weeks old. Birds were killed throughout the growth period and the bone extremities of the pelvic appendicular skeleton prepared for study. The patterns of vascular canals in these broiler fowls were very similar to earlier reports in laying strain fowls. There was a great range of and variation in the vascular morphology of broiler fowl. The physeal vasculature of the rapidly growing broilers was frequently disrupted, and such areas were often associated with dyschondroplastic lesions. The rapidly growing bone extremities in broiler fowls were susceptible to occlusion of epiphyseal vascular canals. lesions were frequently seen at similar sites in different specimens. Links are suggested between the growth rate, weight and behavioural characteristics of broiler fowls and the development of lesions.
肉鸡从孵化饲养至20周龄。在整个生长期间对鸡进行宰杀，并准备好骨盆附属骨骼的骨末端用于研究。这些肉鸡的血管管模式与早期关于蛋鸡品系的报道非常相似。肉鸡的血管形态存在很大范围的差异。快速生长的肉鸡的骨骺血管系统经常受到破坏，并且这些区域通常与软骨发育异常病变有关。肉鸡快速生长的骨末端易发生骨骺血管管阻塞。在不同标本的相似部位经常可见病变。研究表明，肉鸡的生长速度、体重和行为特征与病变的发展之间存在联系。
