Iodine toxicity in ruminants

Abstract

The inadequate intake of iodine is still a topical problem, because it contributes to a reduction in performance through the disturbed health of adult animals and their offspring. The necessity of iodine is frequently described in association with hypothyroidal state. In our work we want to assign the hidden risk of prolonged iodine feeding in ruminants. We discuss the possible sources of iodine intoxication, the clinical signs of the intoxication, its effects on production, reproduction, and thyroid functions; animal susceptibility to intoxication; laboratory and necropsy findings; diagnostic, and therapeutic possibilities.
