Effect of Enzyme Supplementation on Metabolisable Energy of Corn, Wheat and Triticale Grains in Broiler Chickens Using Total Excreta Collection or Marker Methods

One hundred twenty male broiler chickens of 20 d of age were used to study the effect of enzyme supplementation on the apparent metabolisable energy corrected for nitrogen in corn, wheat and triticale using total excreta collection or marker methods. The average apparent metabolisable energy corrected for nitrogen in corn, wheat and triticale on dry matter basis, were 3480 ±90, 3263 ±61 and 3260 ±54 kcal/kg, respectively. The metabolisable energy of wheat and triticale was significantly (
