Canola meal and soybean meal (SBM) are the most commonly used sources of amino acids in diets for swine. However, via genetic selection, varieties of canola with greater concentrations of crude protein and reduced concentrations of fiber have been identified. Following oil extraction, the resulting high-protein canola meal (CM-HP) contains 3 to 5 % more crude protein than conventional canola meal (CM-CV). It is, therefore, expected that CM-HP contains more digestible and metabolizable energy than CM-CV, but this hypothesis has not been experimentally verified (Liu et al., 2016). Therefore, it is the objective of this experiment to determine the apparent total tract digestibility (ATTD) of energy and concentrations of digestible energy (DE) in CM-HP, CM-CV, and SBM when fed to lactating sows.

Soybean meal (SBM) is commonly used as a source of amino acids in swine diets because of its high protein content (Kudelka et al., 2021).  In addition, SBM contributes with energy and phosphorus (P). However, high portion of the P in SBM is bound to phytate, which is indigestible by pigs. Therefore, microbial phytase enzyme is supplemented in swine diets. The impact of phytase on the digestibility of P is well documented, however some experiments on digestibility in corn–SBM diets has been reported energy increase if microbial phytase was used (Liao et al., 2005; Arredondo et al., 2019; Lala et al., 2020; Espinosa et al., 2022), but, not in others (She et al., 2018; Mesina et al., 2019; Lamp and Moritz, 2022). There is, however, a lack of information about the impact of microbial phytase on the digestibility of energy in SBM. It is also not known if a possible effect of microbial phytase on energy digestibility in SBM is consistent among different sources of SBM.

Following oil extraction, the resulting high-protein canola meal contains 3 to 5 percent more crude protein than conventional canola meal. It is, therefore, expected that high-protein canola meal contains more digestible energy (DE) and metabolizable energy (ME) than conventional canola meal when fed to growing pigs. Therefore, experiment was conducted to test the hypothesis that DE and ME in high-protein canola meal is greater than in conventional canola meal.
