Results About the color of these DDGS L * rang from to a * rang from to b * rang from to respecctively. The bulk density rang from 345 to 545 g /L. The average water solubles matter is %. The average content of GE CP EE NDF ADF Ca total phophorus TP and non - phytate NPP are MJ /kg % 9. 06% % % 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 AFB 1 is ~ 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.
