E-mail: [email protected] Seven out of 25 goats from a southern Brazilian lock developed nutritional ibrous osteodystrophy. Affected animals were younger than 1 year of age and were con ined in stalls and fed a concentrate ration containing 1:6 calcium:phosphorus ratio. The remaining lock (35 goats) was managed at pasture and showed no disease. Clinical signs were characterized by mandibular and maxillary enlargements, varying degrees of mouth opening and protruding tongue, dyspnea, apart of abnormalities of prehension and mastication. Affected animals had increased seric levels of phosphorus and parathormone, as well as higher alkaline phosphatase activity. Postmortem examination on three succumbed goats revealed bilateral enlargement of the maxilla and mandibula, and loose teeth, apart of multiple incomplete rib fractures in one of them. Severe diffuse proliferation of loose connective tissue surrounded the osteoid trabeculae, many of which were partially or completely nonmineralized. Mineralized osteoid trabeculae showed osteoclasts in the Howship’s lacunae.
