Abstract

An experiment was conducted to determine the energy concentration in de-hulled full fat soybeans (FFSB). Conventional (FFSB-CV; 435. g crude protein (CP)/kg and 241. g acid hydrolyzed ether extract (AEE)/kg), high-protein (FFSB-HP; 502. g CP/kg and 205. g AEE/kg), and low-oligosaccharide (FFSB-LO; 468. g CP/kg and 211. g AEE/kg) varieties of de-hulled FFSB were used. The digestible energy (DE) and metabolizable energy (ME) in the 3 sources of de-hulled FFSB were determined using 24 growing barrows (initial BW: 28.3. ±. 3.7. kg). A corn-based basal diet and 3 diets containing corn and each source of de-hulled FFSB were formulated. Pigs were placed in metabolism cages and randomly allotted to the 4 diets with 6 replicate pigs per diet. After a 5 d adaptation period, feces and urine were collected for 5 d. The DE and ME in each source of de-hulled FFSB were calculated using the difference procedure. The concentrations of DE and ME in de-hulled FFSB-CV, FFSB-HP, and FFSB-LO were 18.8. ±. 1.17 and 17.4. ±. 1.36; 20.0. ±. 1.62 and 18.3. ±. 1.87; and 19.7. ±. 1.63 and 18.1. ±. 2.16. MJ/kg dry matter, respectively, but no significant differences among the 3 sources of de-hulled FFSB were observed. In conclusion, the same energy values can be used for de-hulled high-protein and low-oligosaccharide varieties of soybeans as the values used for de-hulled conventional soybeans.
