Abstract

Effects of five different batches of wheat distiller's dried grains with solubles (DDGS) were used to investigate bioavailability of energy and nutrients for turkeys. The laboratory analysis of the DDGS showed the largest variations for soluble non-starch polysaccharides, oil and ash. In total, 96 birds were fed one of six mash diets. The basal diet contained per kilogram 535 g wheat and 300 g soya bean meal, corresponding to 247 g crude protein and 12.6 MJ N-corrected apparent metabolisable energy (AMEn). Another five diets contained per kilogram 200 g of each DDGS samples in replacement for basal diet. Each diet was fed to eight pens with two female Premium turkeys following randomisation. The AMEn and the nutrient retention coefficients of the pure DDGS samples were obtained using the substitution method. The AMEn of the DDGS from batch A was higher (p = 0.048) compared to those from batches B and C, but did not differ from DDGS samples D and E. There were no differences in dry matter retention, nitrogen retention and fat digestibility between the DDGS samples tested. The AMEn of the DDGS samples correlated positively (p < 0.05) to the starch (r = 0.895) and the non-soluble non-starch polysaccharides contents (r = 0.940), and the red index of lighting (a) (r = 0.916), respectively. In general, findings from this study indicate bioavailability of energy and most nutrients to be in the range of published data with turkeys, and to vary between batches.
