Day-old broiler chicks were fed diets high in calcium or low in phosphorus for 30 days. Chicks in both groups had similar gross, microscopic, and radiographic lesions. At 2 weeks, the growth-plate degenerating hypertrophied zone (DHZ) and metaphyseal primary spongiosa were lengthened and decreased in radiopacity. Metaphyseal vessels extended to the growth-plate hypertrophied zone (HZ), and osteoid seams were widened. At 3 and 4 weeks, lesions were similar; however, folding fractures were common and cartilage columns of the metaphysis were thinned and replaced with increased woven bone.
将1日龄的肉鸡雏鸡饲喂高钙或低磷日粮30天。两组雏鸡的大体、微观和放射影像学病变相似。在2周龄时，生长板退变肥大带（DHZ）和干骺端初级骨小梁延长，放射不透性降低。干骺端血管延伸至生长板肥大带（HZ），类骨质缝增宽。在3周龄和4周龄时，病变相似；然而，折叠骨折很常见，干骺端的软骨柱变薄，被增多的编织骨取代。
