Abstract

The objective of this study was to evaluate the lighter fraction of DDGS as a possible feedstuff for cattle. To accomplish this, a digestion trial was performed to determine nutrient digestibility and crude protein retention by steers consuming the lighter fraction of DDGS. Steers received L, a diet containing the lighter fraction of DDGS, D, a diet containing whole DDGS, or C, a control diet. Steers receiving L consumed less DM than steers receiving D and C. CP retention and digestibilities of DM, OM, ash, NDF, ADF, HC, and energy did not differ among steers in different treatment groups. Fat digestibility was greatest for steers consuming L and D. Steers consuming L digested more CP than steers receiving C, with steers consuming D being in between. These data suggest that the lighter fraction of DDGS can be effectively fed to cattle without adversely affecting digestibility.
