high-protein canola meal

Digestibility of energy and concentrations of digestible and metabolizable energy in high-protein canola meal, conventional canola meal, and soybean meal in diets fed to gestating sows

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 when fed to sows, but this hypothesis has not been experimentally verified (Liu et al., 2016). Therefore, it was the objective of this experiment to determine the apparent total tract digestibility (ATTD) of energy and concentrations of digestible energy (DE) and metabolizable energy (ME) in high protein canola meal, conventional canola meal, and SBM when fed to gestating sows.

Digestibility of energy and concentrations of digestible and metabolizable energy in high-protein canola meal, conventional canola meal, and soybean meal in diets fed to growing pigs

Canola meal and soybean meal are the most commonly used amino acid sources in diets for growing pigs. However, through 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 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.
