AB  - In a completely randomized design with 3×3 factorial arrangements and 4 replicates, 144 day-old Hubbard  classic  male  broiler  chickens  were  used  to  evaluate  the  effect  of  dietary levels of tallow and NSP-degrading enzyme supplements on nutrient efficiency of broiler chickens. The tallow was used at the levels of 0.0, 2.0 and 4.05%. The enzyme levels added into the diets were 0.0, 0.05 and 0.10%. For nutrient digestibility using Cr<SUB>2</SUB>O<SUB>3</SUB> as indigestible marker, feces samples were collected from 18-21 days of age. Two birds from each replicate of treatment were killed for ileal digesta collection. Apparent metabolizable energy (aME) in all treatments affected by tallow and enzyme levels (p&lt;0.01). Increasing the level of tallow in the diet significantly reduced apparent lipid digestibility of feces (ALD<SUB>f</SUB>) and enzyme addition significantly improved it (p&lt;0.01). This improvement was highest when the level of tallow in the diet was 4%. Apparent protein digestibility (APD) was not affected by treatments but improved when enzyme added to each level of tallow. Apparent lipid digestibility of ileal digesta (ALD<SUB>i</SUB>) was significantly reduced by levels of tallow but enzyme addition improved it (p&lt;0.01).
