Abstract: Iodine deficiency indeed poses a significant concern for both humans and livestock worldwide, and goats are particularly susceptible due to their browsing habits and potential lack of access to iodine-rich sources. Additionally, certain plants (Cabbage, Kale, Broccoli, Cauliflower and Turnips) consumed by goats may contain goitrogens, compounds that interfere with iodine utilization, exacerbating the problem. Clinical iodine deficiency in goats typically manifests as goitre, characterized by an enlargement of the thyroid gland. However, subclinical deficiency, where clinical signs are not readily apparent, can be more challenging to diagnose and have adverse effects on goat health and productivity. Clinical signs of iodine deficiency, such as goitre formation, are often more prevalent in kids (young goats) compared to adults. This heightened vulnerability in kids can be attributed to their rapid growth and development, which increases their demand for iodine. Diagnosis relies on clinical observations of goitre and the evaluation of thyroid hormone levels, along with assessing plasma organic iodine levels. Milk and urine iodine levels serve as reliable indicators of iodine deficiency. Deficiency can be prevented by daily supplementation of iodine. Additionally, it's crucial to avoid feeding goats diets high in goitrogens, substances that can interfere with iodine utilization and exacerbate deficiency symptoms.
