“…In the current study, pigs fed the diets containing HP-SFM had greater THP compared with those fed the P-deficient basal diet, which is likely attributable to an increase in dietary CP content as a consequence of the addition of HP-SFM (Noblet et al, 1994;Le Bellego et al, 2001;Noblet and van Milgen, 2013). Replacing 30% of basal diet with 30% of HP-SFM resulted in a decrease in dietary starch but an increase in dietary CP.…”

“…This is because the efficiency of dietary ME utilization depends on final utilization of dietary energy (i.e., deposition as protein vs. deposition as lipid). According to Noblet and van Milgen (2013), the energetic efficiency of dietary ME utilization is greater for lipid deposition than for protein deposition (80% vs. 60%). Therefore, dietary NE for pigs should be measured using balanced diets that meet nutrient requirements to support optimal growth and lean tissue gain Noblet and van Milgen, 2013).…”

“…According to Noblet and van Milgen (2013), the energetic efficiency of dietary ME utilization is greater for lipid deposition than for protein deposition (80% vs. 60%). Therefore, dietary NE for pigs should be measured using balanced diets that meet nutrient requirements to support optimal growth and lean tissue gain Noblet and van Milgen, 2013). Indeed, Li et al (2018) reported different NE values for corn fed to growing pigs when it was supplemented with dietary crystalline AA.…”

“…Contrary to our hypothesis, however, no differences in the ME (3,057 vs. 3,037 kcal/kg, as-fed basis) and NE (2,062 vs. 2,151 kcal/kg, as-fed basis) of HP-SFM determined using the P-deficient basal diet and the P-adequate basal diet were observed. Theoretically, significantly greater urinary N excretion observed in pigs fed the P-deficient basal diet should be extended to a decrease in ME value of an ingredient because greater urinary N excretion, therefore greater urinary energy loss would lead to underestimation of dietary ME (Noblet and van Milgen, 2013). The lower RE P and the greater RE L that were observed in pigs fed the P-deficient basal diet than in pigs fed the P-adequate basal diet did not result in different NE values in HP-SFM despite the fact that the energetic efficiency of dietary ME utilization for protein deposition is less than for lipid deposition (Noblet and van Milgen, 2013).…”

“…Based on these observations, it can be speculated that DE of the ingredient determined using P-deficient and P-adequate basal diets would not be different because digestibility of energy and nutrients are not affected by dietary P content, but ME would be affected because of increased urinary N excretion, therefore increasing urinary energy loss. The NE of ingredient would also be influenced due to an increase in lipid deposition rather than protein deposition (Noblet and van Milgen, 2013). Therefore, the objectives of the current study were (i) to determine DE, ME, and NE of HP-SFM and (ii) to compare the energy values of HP-SFM determined using either the P-deficient basal diet or the P-adequate basal diet.…”

An experiment was carried out to determine energy values of high-protein sunflower meal (HP-SFM) and to compare the energy values of HP-SFM determined using either a phosphorus (P)-deficient basal diet or a P-adequate basal diet. Twenty-four growing barrows were randomly assigned to 1 of 4 dietary treatments with 6 replicates per treatment. Four experimental diets including 2 basal diets containing 2 levels of standardized total tract digestible P (i.e., P-deficient and P-adequate) and the other 2 diets containing 30% HP-SFM with each basal diet (i.e., HP-SFM 1 diet and HP-SFM 2 diet) were formulated to determine the energy values of HP-SFM and to compare energy values of HP-SFM determined by the difference method using 2 basal diets. Pigs were fed diets for 15 d including 10 d for adaptation and 5 d for total collections. Pigs were then moved to indirect calorimetry chambers to determine total heat production (THP) and fasting heat production (FHP). A reduced (P < 0.01) amount of nitrogen was retained in pigs fed the P-deficient basal diet compared with those fed the other diets. The THP of pigs fed the HP-SFM 1 and 2 diets was greater (P < 0.01) than those fed the P-deficient basal diet with the intermediate value for pigs fed the P-adequate basal diet. The retained energy (RE) as protein of pigs fed the P-deficient basal diet was less (P < 0.01) but RE as lipid was greater (P < 0.01) than those fed the P-adequate basal, or HP-SFM 1 and 2 diets. However, there was no difference in FHP of pigs among the dietary treatments. The NE of HP-SFM determined using the P-deficient basal diet was 2,062 kcal/kg, as-fed basis, whereas the value determined using the P-adequate basal diet was 2,151 kcal/kg. Although no differences were observed in energy values, the amount of P in basal diet might affect energy balance by modifying N utilization, thus, a diet containing adequate amount of P is a more suitable basal diet when the difference method is used for calculation of NE in a feed ingredient.
