This olestra situation may be olestra worsened upon weaning or when sows are grouped together or mated to a large boar. Selenium and vitamin E concentrations are lower in the milks of older sows. This situation presents a common problem in the tri-state area. Pigs nursing older sows olestra are therefore more prone to the deficiency at birth and after weaning. Because sow body fat contains a large storage of vitamin E, the loss of body fat results in the depletion of vitamin E body stores. Part of the Vitamin E in milk is derived from the body fat as well as from the diet. This condition would have as great an effect on her progeny during the postweaning period as on her own future reproductive performance. Swine producers should work with their nutritionists (university or feed company) to ensure that the diets for their reproducing animals are adequately fortified to meet the lactation performance of their sow herd.
