Molybdenum in Poult Nutrition. ∗

Abstract

Summary

(1) Weights of turkey poults fed a purified type diet were increased significantly upon addition of distillers dried solubles, distillers dried solubles ash, molybdenum (0.0254 ppm) or a mixture of distillers dried solubles, dried whey, fish solubles, an antibiotic fermentation residue, and forage juice. Although differences of as much as 2% in bone ash were observed, statistical significance was not obtained. (2) Both liver and intestinal xanthine dehydrogenase activities were significantly higher in supplemented groups as compared to control birds. A significant (P<0.05) correlation was determined between liver molybdenum content and level of enzyme activity. (3) Under the conditions of this study a portion of growth promoting activity of distillers dried solubles ash would appear to be explained on the basis of the molybdenum content.
