ABSTRACT
Two experiments were conducted with chicks to compare the effectiveness of vitamin E,selenium and cystine in preventing the deleterious effects of dietary silver. Adding 900 p.p.m. silver to a diet marginal in vitamin E and selenium significantly depressed growth and caused a high mortality during the four-week experiment. Most of the mortality was due to exduative diathesis. Including either 1 p.p.m. selenium or 100 I.U. vitamin E per kg. in the diets with silver prevented the growth depression and mortality. Adding 0.15% cystine stimulated growth, but failed to rpevent mortality. In a second experiment, chicks were grown on the diet containing silver with and without cystine to 15 days of age, at which time approximately 50% of the chicks exhibited signs of exudative diathesis. At that time they were either continued on the same diet of fed diets supplemented with selenium or vitamin E. Both vitamin E and selenium reduced mortality during the following two-week period, but vitamin E. was more effective than selenium.
