A form of epidemic lameness affecting rapidly growing broadbreasted turkeys of different breeds was investigated in 16 flocks. The condition commenced when birds were between eight and 14 weeks old and was consistenly associated with the development of lesions in the hip. Affected birds first showed leg weakness and ataxia and later chronic postural changes involving the hip. The post mortem lesions were those of inflammation, oedema, ulceration, fibrosis and complensatory hypertrophy of localised areas associated with the hip articulation. The cause was not established but the anatomical features of affected birds, their nutritional status and their apparent freedom from recognised infectious diseased are discussed.
对16个鸡群中出现的一种影响不同品种快速生长的宽胸火鸡的流行性跛行疾病进行了调查。该病在鸡8至14周龄时开始出现，且一直与髋部病变的发展有关。患病鸡最初表现为腿部无力和共济失调，随后出现涉及髋部的慢性姿势改变。尸检病变为与髋关节相关的局部区域的炎症、水肿、溃疡、纤维化和代偿性肥大。病因尚未明确，但对患病鸡的解剖特征、营养状况以及它们明显未感染已知传染病的情况进行了讨论。
