Abstract

The objective of this study was to investigate the effects of dietary inclusion of low-oil corn dried distillers' grains with solubles (LO-DDGS) on growth, carcass traits and beef fatty acids profiles of finishing feedlot cattle. One hundred and eighty British crossbred steers (450±28.5 kg; six pens/treatment) were offered barley grain-barley silage as the control diet with LO-DDGS replacing barley grain at 200 and 300 g kg-1 dry matter basis in treatment diets. Compared with control, LODDGS at 200 g kg-1 did not affect growth performance or carcass traits, whereas at 300 g kg-1 it decreased (P<0.05) gain:feed, but increased (P<0.05) levels of desirable fatty acids in beef. LO-DDGS can replace 200 g kg-1 barley grain in finishing feedlot diets without undesirable impacts on growth performance or carcass traits.
