Effect of Diet Composition on Vanadium Toxicity for the Chick

Abstract

ROMOSER et al. (1961) studied the effect of adding vanadium to a corn-soybean meal diet and found that the addition of up to 20 p.p.m. of vanadium to such a diet was tolerated by the chick. Adding 30 or more p.p.m. resulted in significant growth depression. They further observed that no mortality occurred until 200 or more p.p.m. of vanadium were added.Nelson et al. (1962) using a commercial type broiler ration (composition not given) showed that diets containing less than 20 p.p.m. of vanadium were safe for young chicks. Likewise, no growth depression occurred when 15 p.p.m. vanadium was added to a purified type ration containing dextrose, blood fibrin and gelatin.Hathcock et al. (1964) studied vanadium toxicity with a diet containing 60% dried skim milk and 32.5% glucose. With such a diet the addition of 25 p.p.m. vanadium caused a significant decrease in growth rate and nearly 100% …
