Adding iodine after the goitres have developed won't work because the goitre
is actually an enlargement of the size of the thyroid gland due to an
increase in the number of cells in the gland. This is a response by the body
to a perceived lack of Iodine in the diet/environment as Iodine is an
important component of the Thyroid hormones which of course are important
metabolism regulators.
In human medicine there are well-known Iodine-deficient areas where this
type of goitre is prevalent. BTW "goitre" is not a disease, just an
enlargement of the thyroid gland and a sign of several possible causes, not
only iodine deficiency
