This study was conducted to determine normal rates of growth of different skeletal segments in the thoroughbred horse. Growth of body weight and eight skeletal segments (wither height, hip height, body length, knee to pastern length, hock to pastern length, shoulder to pastern length, width of chest, depth of girth) were monitored in 106 horses (60 colts, 46 fillies) during the period from 14 to 588 d of age. Body weight gains were slightly higher (30 to 40 kg) than previously reported values. Growth in wither height and hip height were similar to previous reports. During the period measured in this study hip height was consistently 2 or 3 cm larger than wither height. Growth patterns for wither height, body length, and shoulder to pastern lengths were similar to one another. Growth of the knee to pastern and hock to pastern segments reached a plateau at approximately 140 d of age, which coincided with the cessation of longitudinal bone growth. These data define skeletal growth patterns in the thoroughbred horse and are useful in determining the relationship between growth and the occurrence of orthopedic diseases in horses.
本研究旨在确定纯种马不同骨骼部位的正常生长速率。在106匹马（60匹公马、46匹母马）14日龄至588日龄期间，监测其体重及八个骨骼部位（鬐甲高、臀高、体长、膝至蹄骨长度、跗关节至蹄骨长度、肩至蹄骨长度、胸宽、胸围）的生长情况。体重增加量略高于先前报道的值（30至40千克）。鬐甲高和臀高的生长情况与先前报道相似。在本研究测量期间，臀高始终比鬐甲高2至3厘米。鬐甲高、体长以及肩至蹄骨长度的生长模式彼此相似。膝至蹄骨和跗关节至蹄骨部位的生长在约140日龄时达到平台期，这与纵向骨骼生长的停止相一致。这些数据定义了纯种马的骨骼生长模式，有助于确定生长与马的骨科疾病发生之间的关系。
