Effect of Glucosinolates on Thyroid Function in Non-Pregnant Mares

Glucosinolates (GSL), which are commonly found in Brassicaceae family plants, may have negative effects on animal health. Major GSL metabolites such as isothiocyanates, thiocyanates and oxazolidinethione disrupt iodine availability to the thyroid, thus causing thyroid dysfunction. Maternal thyroid health and adequate levels of iodine are essential for normal fetal development, especially growth and maturation of the musculoskeletal system in the second and third trimester of gestation. Consumption of plants containing GSL during pregnancy has been linked to congenital hypothyroidism dysmaturity syndrome in foals (CHDS).
