A continuous increase in the circumference of the thyroid gland was observed in four goat kids (44.4%) of the breed of White German Goat between the third and fourth month in a herd comprising White German Goats and Coloured German Goats. Clinical, laboratory diagnostic and chemically analytical results have been obtained, illustrated and compared with the equivalent parameters from healthy control herds without pathological findings. The thyroidal secretion rate and the milk iodine content were highly significant reduced in the affected flock in comparison with the control group. The feed which was given to the affected group did not cover the nutritional requirement of pregnant, lactating and growing goats. At 40-50 mg/l, the nitrate content of the water was close to the tolerance of 50 mg/l. It can be deduced from the findings available that the case described above is a synergetic combination of a primary iodine deficiency, based on an inefficient iodine supply and of a secondary iodine deficiency resulting from a super elevated nitrate content of the drinking water.
在一个由德国白山羊和德国有色山羊组成的羊群中，观察到4只（44.4%）德国白山羊品种的羔羊在第三个月至第四个月期间甲状腺周长持续增加。已获得临床、实验室诊断和化学分析结果，并进行了说明，还与无病理发现的健康对照羊群的相应参数进行了比较。与对照组相比，受影响羊群的甲状腺分泌率和牛奶碘含量显著降低。给受影响组提供的饲料不能满足怀孕、哺乳和生长山羊的营养需求。水的硝酸盐含量在40 - 50毫克/升，接近50毫克/升的耐受值。从现有发现可以推断，上述病例是原发性碘缺乏（基于碘供应不足）和继发性碘缺乏（由于饮用水中硝酸盐含量超高）的协同组合。
