A factorial design experiment was conducted to study the performance of broiler chickens fed five different levels of triticale replaced for corn (0, 25, 50, 75 and 100%), in a corn-soy based diet with/ without exogenous enzyme supplementation. Each treatment diet fed to four groups of ten male birds each. The starter, grower and/or finisher diets were isocalric and isonitrogenous and fed ad libitum from 4 to 10, 11-28 and 29 to 42 d of age, respectively. Similar weight gain, feed intake and feed conversion observed in birds fed control or diets contained up to 75% triticale replaced for corn. However, the average daily feed intake and feed conversion were increased when 100% of corn was replaced with triticale during 4 to 42 d of age (P<0.01). The exogenous enzyme supplementation did not affect broiler performance. Gizzard and small intestine weights increased with an increase in triticale in diet when measured at 18 and 42 d of age. This study revealed that diets containing up to 40% triticale (or 75% of corn replacement) had no negative effect on broiler performance. Whereas chickens blood serum cholesterol and HDL were elevated when fed enzyme supplemented corn or triticale-soy diets.
