The objectives of this study were to evaluate phosphorous (P) digestibility and energy contents of expeller-pressed soybean meal (SBE) derived from Manitoba grown soybeans as a potential source for swine. The study aimed to compare the Manitoba derived SBE with Ontario derived SBE, yielding the results that can be used to showcase the comparative soybean quality in swine nutrition, enhancing the reputation of western Canadian grown soybean in foreign markets and concurrently reducing the dependence on imports. Four SBEs were used in the experiment, with three derived from soybeans grown in Manitoba (MB1, MB2, and MB3) whereas the fourth was derived from soybeans grown in Ontario. Experiment 1 was conducted to determine the apparent total tract digestibility (ATTD) of calcium (Ca) and P and standardized total tract digestibility (STTD) of P in SBE and to examine the effects of microbial phytase supplementation on ATTD and STTD of P in SBE. The STTD values of P with and without phytase supplementation averaged 69.9% and 79.7%, respectively. The ATTD and STTD of P were not different among the SBE types. Phytase supplementation increases the P digestibility in SBE irrespective of source. Experiment 2 was conducted to determine the digestible energy (DE), metabolizable energy (ME) and net energy (NE) content in SBE derived from Manitoba and Ontario regions. Manitoba and Ontario derived SBEs were not different in terms of DE, ME and NE contents when fed to growing pigs. The average contents of DE, ME and NE in studied SBE was 4280, 4056, and 2986 kcal/kg DM, respectively. Manitoba derived and Ontario derived SBE were not different in terms of P digestibility and energy content. Thus, average values of STTD of P, and NE values can be efficiently utilized in swine diet formulations. In conclusion, western Canadian grown soybeans hold promise as a viable protein ingredient for swine nutrition, however, further studies are necessary to understand its full potential.
