Abstract: We anlysed the color(L^*,a^* and b^*),bulk density,water solubles matter and conventional nutritive components of 17 DDGS(A-Q) from different sources in China,and determined the AFB1 and melamine in 10 DDGS(A,B,C,E,F,G,H,L,O and Q) among them.Results:About the color of these DDGS,L^* rang from 33.32 to 44.34,a^* rang from 6.08 to 10.43,b^* rang from 7.45 to 15.42,respecctively.The bulk density rang from 345 to 545 g/L.The average water solubles matter is 26.17%.The average content of GE,CP,EE,NDF,ADF,Ca,total phophorus(TP) and non-phytate(NPP) are 19.07 MJ/kg,27.85%,9.06%,42.20%,12.81%,0.07%,0.64% and 0.56% respectively.The variation in color(L^*,b^*),bulk density,water solubles matter,GE,DM,CP,EE,NDF,Ca,TP,NPP within plants(A and B,C and D,H and I) lower than between different plants(A-Q).The EE content of A,B,C,D,F,P and Q is less than 6%.The DDGS water solubles matter positive correlated with TP and NPP.The DDGS AFB1 is 2.33~22.45 μg/kg and the melamine was not detected by High Performance Liquid Chromatography in the DDGS.There is higher variability in physical properties and nutrient level of DDGS from different raw material and different raw material The 10 DDGS in this experiment are safety for feedstuffs.
