[Improving the human iodine supply by iodination of swine feed].
Germany and several other countries are areas of severe iodine deficiency. In addition to iodized salt additional strategies to fight iodine deficiency exist. A promising possibility is the supplementation of feed with iodine, in order to increase its content in food of animal origin. In a feeding experiment 24 male castrated and female piglets of the cross breed Deutsche Landrasse x Pietrain were fed a high iodine supplemented diet. At a body weight of 100 kg the animals were slaughtered and the effect of the iodine supplementation on iodine content in the organs was studied. Animals receiving 30 mg iodine/kg feed showed significantly higher iodine contents in muscle, heart, kidney, liver, serum, fat and in the thyroidea than animals receiving no iodine supplementation. The iodine content in muscle and organs increased by a factor three to seven. Concerning meat quality and other slaughter parameters there was no difference between the two groups. This demonstrates that this strategy is in addition to iodized salt a possibility to reduce iodine deficiency.
