The Food and Drug Administration has approved sodium selenite and sodium selenate as supplements to pig starter diets up to a level of .3 parts per million (ppm) of selenium. In view of this, the potential exists for selenium poisoning to occur through accidental contamination, incorrect mixing or incorrect formulation of the diet. However, little research has been conducted to determine the maximum level of dietary selenium that could be tolerated without affecting pig performance.
The objectives of this study were to establish the level at which selenium becomes toxic to growing swine and to determine which of the parameters evaluated is the best indication of chronic selenium poisoning.
