Changes in the hormonal status of cows with subcutaneous administration of an iodine-containing drug

One of the most important aspects of maintaining the health of animals is to meet their needs for nutrients, vitamins and minerals. To solve this problem, it is necessary to optimize the diets of animals. However, when talking about the territory of the Altai Territory, it should be borne in mind that the soil and, accordingly, the plants growing on it, can not meet the need of cattle in such a trace element as iodine. It is obvious that it is necessary to introduce a qualitatively new way to solve this problem in cows. The most productive, in our opinion, is the method of subcutaneous administration of Kayod tablets. Testing of this method was carried out on pregnant cows of the uchkhoz «Prigorodny». Three groups of pregnant cows with 15 animals each were formed for the research. A preliminary analysis of the diet was made, according to which the iodine deficiency was 15 % per animal. During the experiment, cows of different groups were implanted under the skin with Kaiod tablets in different dosages, after which the hormonal parameters of the cows « blood were examined to determine the content of thyroxine and triiodothyronine in it. The study of the dynamics of these indicators most clearly characterizes the presence or absence of hidden pathological processes in the animal’s body that affect the metabolism, and, accordingly, are directly related to iodine deficiency or its absence. Based on the above, it is necessary to conclude that the use of Kaiod tablets in cows during pregnancy in the form of subcutaneous implants according to the method developed and implemented by the authors is a very productive way to normalize the function of the thyroid gland in cattle. The correction of the metabolism begins immediately after the implantation of the tablets and continues to work for 2–3 months in the future.
