This thesis deals with the activity of a thyroid gland of a goat in terms of an excessive iodine excretion in urine and milk. The milk iodine content as a potential source of iodine for humans is still a significant affair. Five milk collections were done in five observed farms during a lactation period. It was collected 144 individual mixed milk samples from 32 animals in total. Urine collections were made five times in the five observed farms 29 individual urine samples in total from 12 animals. The total iodine excretion in milk and urine was set. The average iodine content in milk of individual farms ranged from 41.72 to 143.54 ?g I.l-1 and the average iodine content in urine of individual farms ranged from 104,1 to 165,3 ?g I.l-1. It appears from that that type of stabling and also ration with mineral supplements have an impact on the iodine content. No impact on the iodine content was registered from lactation stage, age or specific breed. There's possible dependency on iodine content in milk and iodine content in urine.
