SAMUEL GOLDZVEIG M.1 Y CARMEN VISCONTI P.2
 

It was determined protein-bound iodine levels in the blood samples of cows from first to sixth partum, in dairy farms of the Province of Santiago during the months of November and December.
The method of Brown modified by Lennon and Mixner was used.
The average of plasma protein-bound iodine in the different partum range between 4,588 and 6,918 mcg per 100 ml.; the values were a little higher than those given by foreing researches for cows (4,6 mcg per 100 ml.).
There was a significant diffel'ence between the values of the first partum with the secondand third, and fram the second with the fourth. There was not a significant difference among the other comparisons.
In the literature no reports were found about protein-bound iodine in blood of cows of different partum.
