The general purpose of this project is to improve the use of deoxynivalenol (DON)-contaminated diets through better knowledges of the effects of DON on feed digestibility. Specifically, the objectives are 1- to determine the effects of DON on the ileal digestibility of amino acids and total digestibility of phosphorus and calcium and 2-to evaluate the effect anti-mycotoxin additive on digestibility DON-contaminated feeds. In fact, even if it is know that DON can affect the total digestibility of feed, the specific effects of DON on the digestibility of amino acids, phosphorus and calcium were not clearly known. Furthermore, some anti-mycotoxin additives can be effective in reducing negative effects of DON on growth, but the potential effect of these additives on the availability dietary nutrients in DON-contaminated diets need to be determined. The results obtained in this project will have a short and long term impact to a better use of mycotoxin contaminated feeds, especially with DON. This project will also open several areas of investigation that will allow to understand the underlying mechanisms of the effect of DON on nutrient digestibility and thus the availability of nutrients for the animal. Finally, by developing new strategies to use efficiently contaminated feed this project will contribute to use more efficiently feed resources and develop farming techniques to maintain the competitiveness of Canadian swine industry.
