congenital hypothyroid dysmaturity syndrome

of foals occurs predominantly in the prairie provinces of Canada and the Pacific Northwest and is manifest by prolonged gestation, dysmaturity and limb deformity due to delayed ossification of the carpal bones. Histologically, but not grossly, there is thyroid hyperplasia. In Canada, the syndrome has been associated with high nitrate concentrations in feed, but in the western United States epidemiological data suggest it occurs in late-foaling mares and results from ingestion of goitrogenic winter annual mustard species in the latter three months of gestation.
