Iodine, an essential trace element:
Iodine is a constituent of thyroxine, a growth hormone secreted by the thyroid. It supports the energy metabolism and is important for lactation, reproduction and fattening young animals. The results of an iodine deficiency is goitre, rough coats, slower growth and infertility.
Fodder is naturally low in sodium and iodine.
According to INRA, in 2007, average iodine levels in green fodder were 0.1 to 0.3 mg per kg DM for grasses, 0.2 mg per kg DM for legume fodder and 0.1 mg per DM for maize silage, compared to minimum RDAs of 0.5 mg per kg DM. Iodised salt feed supplements help to better meet dairy livestock needs as high levels of iodine are lost in milk.
