Iodine and oxidative stress
Abstract
The aim of the present study with fattening pigs is to investigate the potential contribution of very hich dietary doses of iodine close to the maximum permitted dietary iodine contents to induce symptoms of oxidative stress. For this purpose 100 fattening pigs of the Austrian Hybrid Breeding Program (OEHYB) are divided into 5 groups and receive different levels and sources of dietary iodine during the entire period of fattening (control 200 ppb; iodine from iodide: 5.000 ppb or 10.000 ppb; iodine from iodate: 5.000 ppb or 10.000). Growth and slaughter performance are measured, oxidative status is recorded by enzymatic parameter and gene expression data in relevant tissue samples and in blood, and concomitant tissue iodine contents are analyzed.
