INTRODUCTIONβ-mannans are plant cell wall polysaccharides of D-mannose units linked by β-(1-4) glycosidic bonds (Lee and Brown, 2022). β-mannans are a complex carbohydrate and may consist of a long chain of only mannose units or a chain of mannose units with side chains of α-1,6-linked galactose or glucose residues, resulting in galactomannans or galactoglucomannans, respectiv ...

Values for digestible energy (DE) and metabolizable energy (ME) in feed ingredients are usually determined in growing pigs and subsequently applied to all groups of pigs. Results of recent re search, however, indicates that the energy concentration of soy bean meal (SBM) is greater than previously thought when fed to growing pigs (Sotak-Peper et al., 2015; Lopez et al., 2020; Lee et al., 2021). Th ...

1. IntroductionReducing the particle size of cereal grains increases the digestibility of starch and energy by pigs (Huang et al., 2015; Rojas and Stein, 2015; Lee et al., 2024) and it is likely that surface area of grain particles and interactions between particles and digestive enzymes are increased by reducing particle sizes. In contrast to the demonstrated improvement in the digestibility of ...
