Diagnosis is based on the results of laboratory studies of soil, water and feed on the iodine content , as well as milk. In affluent areas in 1 liter of milk contains more than 60 micrograms of iodine . Inclusion in the diet of animals of iodine in the form of potassium iodide at the rate of 3 mg per kg of body weight , the use of iodized salt or spraying a solution of potassium iodide food treats and prevents the development of endemic goiter . enzootic ataxia Enzootic ataxia, or gipokuroz — uterine disease in lambs and post-uterine periods characterized by organic and functional changes in the brain and spinal cord , causing huge economic losses . Lambs death reaches 40-60 % of the number of births , 80-90 % of cases do not grow and develop. And adults suffer gipokurozom sheep .
The reason — a copper deficiency or excess of its antagonists ( molybdenum, lead ) in soil and plants growing on it . The disease is recorded in the provinces , wherein the content of copper in fresh grass less than 4.6 mg / kg, molybdenum sulphate , and 5-6 times 4-5 times longer than in the well — regions. If enzootic ataxia in ewes marked anemia, exhaustion, reduced amount of hair , abortion, birth immature , ugly or dead lambs. Lambs marked with severe paresis, paralysis . Often paralyzes registered at birth . Lambs are thrown back on his back with a shovel or head, with elongated limbs , sometimes will make swimming motions limbs.
Mortality rate is 100% . In mild form appears clinic for 2-3 months of life , to put it in violation of coordination, unsteadiness of gait, stumbling . Lambs often fall on the side or take the dog sitting posture (Fig.
30) . In the future, anemia , emaciation and death to 40-80 % of patients. Fig . 30.
