Iodine I content of rations is a factor associated with the blood concentration of thyroxine T 4 and triiodothyronine T 3 in cattle. In herds from southern Chile, low blood concentrations of T 4 in grazing dairy cows have been reported.

The objective was to obtain information about the I content in forage samples from dairy farms in the IXth and Xth Regions of Chile.

During forage samples were taken from 25 dairy farms located in both Regions. The I concentration was analysed by a kinetic-colorimetric method. Mean, standard deviation and ranges and the frequency of samples with values below 0.

The average of I concentration in the forage samples was 0. Forage with normal concentrations were not found. These results suggest an I deficiency in forage from southern Chile, and may be associated with low blood concentrations of T 4 in grazing dairy cows. No se observaron concentraciones adecuadas de I en las muestras de forraje analizadas en ambas Regiones, siendo 0.
