The main purpose of agriculture and livestock industry is important in the production in the increasing number of food for the population and raw materials for industry. Agriculture is currently gaining importance in the socio-economic development of the North-Kazakhstan region, while being its priority requires addressing program- target method by farming with the introduction of new high technology that includes the use of biotic doses of trace elements in livestock. It should be noted that the physiology of farm animals in biogeochemical conditions of the North Kazakhstan region has not been studied enough, and the effect of lack of iodine on the body of cattle has not been studied either. Trace element iodine fulfills an important biological role in the body of the animal, ultimately affects the productivity and quality of reproductive animals [1]. Over 90 % of iodine required for farm animals comes from vegetable foods and forage plants. Mineral soil composition, typical for each biogeochemical zone, determines the composition of forage plants, especially those grown in meadows and pastures. The average content of iodine in pasture plants in our country is 0.18 mg/kg [3]. The territory of the North Kazakhstan region is biogeochemical province for lack of iodine. There is not enough iodine in the water, earth, plants that grow on it , and in animals living on its open spaces [2].

The objective of our research:

- Examine the condition of iodine deficiency at the farm Novoishimsky rural district (North Kazakhstan region) by IFA method. - Carry out preventive activities with the use of potassium iodide and zeolite.

For the development of preventive measures production experiment was organized. For this purpose, two groups were matched for five cows each. Group formed by analogy, that is, animals of the same breed, similar age, weight, performance, conditions of feeding and keeping. [4]

The first experimental group in addition to the basic diet received fertilizer complex consisting of 9mg of potassium iodide and 200 grams of natural zeolite. Second - served as a control.

Before the start of the experiment and after its completion, blood samples were taken and sent to the district veterinary research laboratory.

Determined amount of hormone thyroxine in serum by IFA (immunosorbent analysis). In the beginning of the experience the amount of serum in cows was: in the first group 725,00 ± 1,76, in the control group contained iodine 645,33 ± 7,26 nmol/l.

Comparing our results with published data, we can conclude that before feeding trace elements in blood serum of experimental animals contained a reduced amount of total iodine. Throughout the period of experiments total iodine content in the blood of the first and second experimental groups gradually increased from 725,0 ± 1,76, 645,33 ± 7,26 nmol/l and reached a maximum value at the end of the experience (952,7 ± 2 , 07 , 947,0 ± 2,12 nmol/l respectively). Of the above it can be concluded that under the conditions of iodine deficiency in economy of Novoishimsky rural district (North Kazakhstan region) for early diagnosis by IFA is suitable and preventive measures using potassium iodide are effective. For the diagnosis of iodine deficiency recommended the use of the test system "T4-IFA-VECTOR-BEST " and is necessary to introduce in industrial activity in the economy in the North Kazakhstan region .
