Abstract: Fluoride is highly toxic and corrosive gas, light yellow-green in colour and with a pungent smell. The excess fluoride intake is responsible for dental and skeletal fluorosis in cattle. The symptoms of excessive fluoride ingestion include lesions in the developing dentition, skeletal lesion and lameness. The immature animals are reported to be most susceptible to dental fluorosis. The milk production is indirectly affected by fluoride toxicosis . The excessive fluoride reduces the conception rates of cattles.
