Popis: Thirty multiparous lactating cows were divided in three groups based on milk yield: high (H), average (A) and low (L). Within each group, cows were randomly allotted to two levels of iodine inclusions into the diet and respectively: level 1 (1): base diet containing 1.55 mg/kg dry matter, level 2 (2): base diet plus 47.2 mg/d. Potassium iodide was used. Feeds, orts, drinking water and individual milk samples were collected and analysed for the iodine content. The iodine concentration and total excretion in milk were affected by the level of iodine supplementation (P
