Plain-English summary
This study looked at two newborn Arabian foals that developed goiter, which is an enlargement of the thyroid gland, because their mothers were given too much iodine during the last six weeks of their pregnancies. In addition to these foals, six other nursing foals and two mares also showed signs of thyroid enlargement. The mares received a daily iodine dose that was at least twelve times higher than what is considered safe. The researchers found that about 2% of the mares and 9% of the foals were affected by this condition. The treatment and outcomes for these cases were not detailed in the abstract.
Abstract
Naturally occurring goiter cases are described in 2 newborn Arabian foals whose mares were supplemented with excess iodine during the final 24 w of the pregnancy. Six nursing foals and 2 mares were also affected clinically with thyroid hypertrophy. At least 12 times the maximum tolerable level of iodine supplementation was given, as the daily iodine intake for each mare was 299 mg. The prevalence of goiter cases was 2 and 9% in the mares and foals, respectively.
