Spencer, H C

Fluroide particles from chemical plants, which are carried through the air and settle on vegetation, are causing problems of fluorosis in cattle in the Ohio Valley. The permanent incisor teeth of cattle were examined as the first step in diagnosing fluorosis. Classification is based on a subjective appraisal of the extent of chalkiness, hypoplasia, abrasion, staining, and wear. The second step in making a tentative diagnosis of fluorosis is to pool representative urine samples. Urinary fluorine content of 8 ppm is normal. The third and most reliable means of confirming a diagnosis is bone analysis. As fluorine concentrations approach 6000 ppm, clinical signs of fluorosis start appearing. Signs of fluorosis include lameness, stiffness, treading of the feet, and inability to stand still. 4 figures.
