Abstract
This study assessed the value of triticale dried distillers grains with solubles(DDGS) in a feedlot finishing diet using 144 intact, and 16 ruminally cannulated crossbred yearling steers. Substituting triticale DDGS for a portion of dry-rolled barley grain (20% diet DM) decreased the prevalence of ruminal acidosis and tended to increase dry matter intake and fat deposition, but increased the incidence and severity of liver abscesses. Further substitution of triticale DDGS for barley silage (5 and 10% diet DM) increased the prevalence of ruminal acidosis, but tended to improve feed efficiency without affecting carcass characteristics. These findings suggest that feedlot finishing diets containing triticale DDGS allow producers to decrease dietary forage inclusion without affecting performance, but may require use of an antimicrobial to control liver abscesses.
