The aim of this study was to evaluate the influence of iron deficiency on the thyroidal function and hormone T3 and T4 concentration in piglets before weaning. We used 40 Landrace × Czech Large White piglets before weaning in this trial. They were divided into two groups. The control group was supplemented with iron after birth, the experimental group was without iron supplementation after birth. Iron, T3 and T4 and haematology indicators were observed. Piglets in the experimental group developed serious anaemia. The iron serum concentration in the experimental group was significantly lower than in the control group. Significant difference in T3 and T4 hormone concentration was found between the experimental and the control group. At the age of 17 and 25 days we found the negative effect of iron deficiency on the thyroid hormone production.
