N,N1-Diphenyl-P-Phenylenediamine in the Prevention of Vitamin E Deficiency in the Lamb

Abstract

Newborn lambs were maintained on an artificial milk diet containing tocopherol-free lard as a source of fat. The effectiveness of N,N¹-diphenyl-p-phenylenediamine (dppd) in preventing the occurrence of clinical and histological signs of muscular dystrophy was determined. Administration of dppd at a level equivalent to 0.10% of the dry matter content of the diet completely prevented the appearance of vitamin E deficiency. A level of 0.025% was found to be slightly inadequate and 0.001 % was ineffective. Copyright © . .
