Influence of arsenic, sulfur, cadmium, tellurium, silver and selenium on the selenium JM-vitamin E deficiency in the pig

; ;
Two experiments were conducted to study the effects of supplemental arsenic, sulfur, arsenic + sulfur, cadmium, cadmium + vitamin E, tellurium, silver and selenium on the selenium metabolism of pigs consuming a low selenium-vitamin E diet. A degenerative myopathy of skeletal muscles was the most prominent of the classical selenium-vitamin E deficiency lesions. Protection provided by 0.01 ppm selenium was incomplete. Low dietary additions of arsenic, sulfur, cadmium and tellurium had no effect on increasing the incidence of a selenium-vitamin E deficiency. Both cadmium and tellurium lowered testicular selenium while cadmium + vitamin E resulted in no effect. Supplemental selenium netted a greater daily retention of this element and substantially increased tissue selenium in comparison to basal pigs. Arsenic decreased selenium retention and resulted in lower tissue concentrations with the exception of the renal cortex. Sulfur lowered selenium retention and resulted in decreased concentrations only in blood. Silver supplementation increased the severity of a selenium-vitamin E deficiency, tended to increase selenium retention and dramatically lowered blood selenium while elevating hepatic selenium.
