Sixty-three boars of the Swedish Landrace and the Yorkshire breed were progeny tested. Production variables were correlated with frequency of osteochondrotic lesions at three sites, length of radius, and presence of leg weakness in 416 offspring. Osteochondrotic lesions in distal femur and humerus were found to be correlated with desirable production variables. No correlation existed between presence of osteochondrosis and leg weakness. Analysis of variance showed that breed and boar within breed influenced frequency and distribution of osteochondrosis. The pigs of the Yorkshire breed were less affected. Heritability estimates ranged from 0.14 to 0.30 for the osteochondrotic lesions at three sites. It should be noted that these figures are preliminary because of the limited number of offspring. It was concluded that a possibility exists to lower frequency of osteochondrosis in the pig with only some loss of valuable production qualities.
对63头瑞典长白猪和约克夏猪进行了后裔测定。在416头后代中，将生产变量与三个部位的骨软骨损伤频率、桡骨长度以及腿部虚弱情况进行了关联分析。发现股骨远端和肱骨的骨软骨损伤与理想的生产变量相关。骨软骨病的存在与腿部虚弱之间没有相关性。方差分析表明，品种和品种内的公猪会影响骨软骨病的频率和分布。约克夏品种的猪受影响较小。三个部位骨软骨损伤的遗传力估计值在0.14至0.30之间。需要注意的是，由于后代数量有限，这些数字是初步的。得出的结论是，在猪中降低骨软骨病频率是有可能的，只是会有一些宝贵生产性状的损失。
