Influence of various Iodine supply on growing-finishing performance and on Iodine status of pigs

摘要

Iodine is essential for man and animals. In the prevention of iodine deficiency, there are efforts to concentrate the trace element in milk, eggs and meat by iodine addition to the feed (beside the salt iodination regarding food). To improve the content of iodine in meat by feeding there are very different results of experiments reported in the literature (He et al, 2002; Schone et al., 2002). For example, there is a very small range between human requirements (circa 200 mu g/d) and the 'upper level' (500-600 fig/d) of iodine. Therefore, the EFSA(2005) asked for more dose-response studies with food producing animals to assess the contribution of various sources of iodine intake in men.
