Five experiments were conducted with growing chicks to determine the effectiveness of various materials in modifying the toxicity of vanadium. The toxicity of vanadium (as it is measured by growth depression and mortality) was much greater when vanadium was added to a semipurified diet than when it was added to a practical diet containing natural ingredients. When EDTA was added to diets containing 50 to 200 p.p.m. vanadium, the growth depression was reduced from 22.1% and 75.9% to 8.4% and 36.7% respectively, and the mortality was reduced from 80% to 20% among chicks fed 200 p.p.m. vanadium. The addition of 10% lactose to a diet containing 100 p.p.m. vanadium increased the growth depression from 41% to 76.2% and caused 80% mortality. Chromium added to diets containing 100 and 200 p.p.m. vanadium improved the growth and reduced the mortality.
用生长中的雏鸡进行了五项实验，以确定各种物质在改变钒毒性方面的效果。当钒添加到半纯化日粮中时，其毒性（通过生长抑制和死亡率来衡量）比添加到含有天然成分的实用日粮中时要大得多。当向含有50至200 ppm钒的日粮中添加乙二胺四乙酸（EDTA）时，生长抑制率分别从22.1%和75.9%降至8.4%和36.7%，并且在饲喂200 ppm钒的雏鸡中，死亡率从80%降至20%。向含有100 ppm钒的日粮中添加10%乳糖，使生长抑制率从41%提高到76.2%，并导致80%的死亡率。向含有100和200 ppm钒的日粮中添加铬可促进生长并降低死亡率。
