  1. Female (F) and castrated (C) pigs in this study originated from five commercial pig producing farms and one pet farmer. The pigs included in this study were both male and female pigs between six and fourteen weeks old. The Se source used in the complete feed was sodium selenite (NaSe) and added levels of NaSe were between 0.33 and 0.40 mg/ kg feed. The vitamin E (vit E) source was alpha tocopherol and added levels were between 100.00 and 200.00 mg/ kg feed. The grower-finisher pigs from Farm 1 were fed liquid feed in combination with whey from approximately 30 kg bodyweight or approximately ten weeks of age. *Iron treatment of the piglets was applied within the first four days of life, either by injecting 200 mg subcutaneously or providing 300 mg of bioavailable iron per os combined with iron-enriched peat until weaning
