Abstract

DDGS has some disadvantages (high fiber content, possible heat damage of amino acids) which may be able to be improved with a newly developed technique called bioconversion (a special fermentation technique). The purpose of this study was to determine the effect of DDGS and bioconverted DDGS on the N, P and energy digestibility and retention of piglets. Twenty-four weaned piglets weighing 8-10 kg were housed individually in a flat-deck cage. The diet of piglets in the control group did not contain DDGS, while other three diets contained DDGS or bioconverted DDGS in increasing amount: 5, 10 or 15%, respectively. The experimental diets had similar nutrient content. The results of this study indicated that corn DDGS and bioconverted DDGS had similar values for energy digestibility and retention.The average DE for the corn DDGS that was calculated in the present experiment was 14.42 MJ/kg of DM, and the average ME was 13.8 MJ/kg of DM. Adding increasing amounts of untreated DDGS to the diet tended to increase P digestibility and retention in the experiment. While the bioconversion improved both phosphorous digestibility and retention. Calcium digestibility and retention were similar for weaned piglets fed the DDGS diet compared to the bioconverted DDGS diets. Our research confirms that even 15% corn DDGS can be included in diets of weaned piglets if highly digestible other components are used. The bioconversion does improve the feeding value of corn DDGS, but the actual inclusion in practical feeding will be depended on economical considerations.
