The direct capabilities and possible interactions of selenium, vitamin E, ethoxyquin and DPPD to prevent exudative diathesis (ED) and death was assessed in selenium- and vitamin E-depleted chicks. There was a strong interaction (P < 0.001) between selenium and vitamin E and a weak interaction (P < 0.05) between selenium and ethoxyquin for prevention of death. Deaths without signs of ED were observed when 300 or 500 ppm ethoxyquin or a combination of 200 ppm ethoxyquin and 1000 ppm DPPD were fed. These findings were interpreted as an inability of synthetic antioxidants in the presence of low levels of selenium and vitamin E to prevent death due to a selenium deficiency while partially capable of preventing ED.
