The NE of SBM for growing pigs with body weight from 47 to 110 kg was determined in the current study using the growth assay. In the first study, a total of 826 pigs (BW, 46.8 ± 2.5 kg) in 44 pens (18-19 pigs per pen, 11 pens per treatment) were randomly allotted into one of 4 dietary treatments with initial body weight and sex as blocks for 21 days: Corn-SBM based diets with 29.0, 25.7, 22.3, or 19.0% of SBM. Compared with the first study, the second study was conducted with a total of 820 pigs at greater BW (67.0 ± 3.4 kg). Pens were randomly allotted into one of 4 dietary treatments for 42 days: Corn-SBM based diet with 29.0, 25.0, 21.0, or 17.0% of SBM. NE of corn (2,674 kcal/kg, as fed basis, DM 87.1%) was calculated according to NRC (2012) and determined with the analyzed nutrient composition. SBM used in both experiments contained 89.4% of DM, 46.6% of CP, 5.9% of starch, 1.6% of EE, 8.5% of NDF, 6.3% of ADF, and 6.1% of ash. The reduced level of SBM was replaced with corn and crystalline amino acids. Data were analyzed by linear and quadratic contrasts using the Proc MIXED of SAS. In the early growing phase (47 to 67 kg), increasing SBM levels from 19.0 to 29.0% tended to linearly decrease ADFI (Linear, P = 0.081, 2.09, 2.03, 2.03, and 2.00 kg/d) but did not affect ADG or final BW. On the contrary, increasing SBM levels decreased ADG and ADFI in pigs growing from 67 to 110 kg (linear, P < 0.05, ADG: 1.03, 1.02, 1.01, and 1.00 kg/d; ADFI: 2.72, 2,64, 2.63, and 2.58 kg/d). Linear regression analysis showed that, to maintain calorie efficiency, the estimated NE of SBM for pigs growing from 47 to 67 kg is 3,000 kcal/kg (as fed basis), which is 1.12 times of corn NE. The estimated NE of SBM for pigs growing from 67 to 110 kg is 2,705 kcal/kg (as fed basis), which is 1.01 times of corn NE.
