Losses due to skeletal disorders varied from 1.8 to 6.1 percent in five flocks, varying in size from 2040 to 7033 birds, of broad breasted white tom turkeys. Very little evidence of significant air-sacculitis due to Mycoplasma meleagridis was found in hatching poults or during the growing period. Major disorders causing the losses included rickets, rotated tibia, arthritis/osteomyelitis and long bone distortion. Rickets and arthritis/osteomyelitis due to infection with Staphylococcus aureus were significant problems only in one flock each, while rotated tibia caused significant losses in three flocks. Long bone distortion was the major cause of economic loss and occurred in all flocks. Possible causes of long bone distortion are briefly discussed.
在五个鸡群中,骨骼疾病造成的损失在1.8%至6.1%之间,这些鸡群为宽胸白羽公火鸡,数量从2040只到7033只不等。在雏火鸡孵化时或生长期间,很少发现有因火鸡支原体引起严重气囊炎的迹象。造成损失的主要疾病包括佝偻病、胫骨扭转、关节炎/骨髓炎和长骨变形。仅在其中一个鸡群中,由金黄色葡萄球菌感染引起的佝偻病和关节炎/骨髓炎成为严重问题,而胫骨扭转在三个鸡群中造成了重大损失。长骨变形是经济损失的主要原因,且在所有鸡群中均有发生。文中简要讨论了长骨变形的可能原因。
