He, M. L., Xu, L., Yang, W. Z., Gibb, D. and McAllister, T. A. 2014. Effect of low-oil corn dried distillers′ grains with solubles on growth performance, carcass traits and beef fatty acid profile of feedlot cattle. Can. J. Anim. Sci. 94: 343-347. 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, LO-DDGS 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.
