Studies on Encephalomalacia in the Chick

“…(Abstract, Poultry Sci. 32: 924, 1953 a low vitamin E reserve (Singsen et al, 1954;Singsen et al, 1955). Dam (1944) has also tested three different fractions of hog liver fatty acids and found that the effectiveness of these acid fractions in producing exudative diathesis and encephalomalacia in chicks reared on a vitamin E deficient diet is related to the iodine values of the acids.…”

Studies on Drug Toxicity in Chicks

“…Ames and Harris (19S0) considered two functions for vitamin E. A specific action through an enzyme system and a nonspecific function as a physiological antioxidant. Bunnell et al (1955) concluded that DPPD and other antioxidants, including vitamin E, function in vivo as an antioxidant or electron-transferring agent in some cellular reaction which results in the prevention of encephalomalacia. Dam (1949) found some relation between encephalomalacia and the unsaturated fatty acids.…”

Utilization of Vitamin A Activity from Alfalfa or Fish Oil by Chicks Receiving Diets with and without Diphenyl-P-Phenylenediamine (DPPD)

“…The Borden Company, Elgin, Illinois (Received for publication July 26, 1956) S INCE the report by Singsen et al (1955) that certain antioxidants including diphenyl-p-phenylenediamine (DPPD) are effective in preventing experimentally induced encephalomalacia, there has been considerable interest in these compounds and their effects when added to poultry feeds. Previously, Dam et al (1948Dam et al ( , 1951 reported that certain substances having antioxidant activity afforded partial protection against certain vitamin E deficiency symptoms.…”
