Soybean hulls

Digestible and metabolizable energy in soybean meal and soybean hulls when fed to growing pigs or sows

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 research, however, indicate that the energy content of soybean meal (SBM) is greater than previously thought when fed to growing pigs. This increase in energy may be due to changes in the pigs themselves or differences in methodology, but there are no recent experiments assessing DE and ME in SBM when fed to sows. Therefore, it remains unclear if sows also have greater DE and ME in SBM compared with current book values. Likewise, there are no recent data for the DE and ME in soybean hulls although soybean hulls are often added to diets for gestating sows. Therefore, an experiment was conducted to test the hypothesis that gestating and lactating sows have greater DE and ME in SBM and soybean hulls than growing pigs and that DE and ME in SBM fed to both growing pigs and sows are greater than current book values. The second hypothesis was that there is no difference in apparent total tract digestibility (ATTD) of gross energy (GE) and DE between gestating and lactating sows.

Digestibility of energy by gestating and lactating sows and concentrations of digestible and metabolizable energy in diets containing pistachio shell powder or soybean hulls

California is a leading producer of pistachios in the United States and globally and it is estimated that annual production will reach 2.08 billion pounds in 2031. As a result, about 31.2 million pounds of shells will be produced after the nuts are processed for human consumption. Pistachio shells have been viewed as a waste product and are frequently disposed of using ecologically friendly practices. However, it is possible that pistachio shell powder can be used as a high fiber ingredient for swine. Specifically, gestating sows may benefit from the high fiber concentration in pistachio shell powder because this may increase satiety and reduce stress. However, at this time, there is no information about the nutritional value of pistachio shell powder when fed to sows. Therefore, an experiment was conducted to test the hypothesis that apparent total tract digestibility (ATTD) of gross energy (GE) and concentrations of digestible energy (DE) and metabolizable energy (ME) in pistachio shell powder are not different from those in soybean hulls when fed to gestating sows. The second hypothesis was that the ATTD of GE and DE in pistachio shell powder are not different from those in soybean hulls when fed to lactating sows.
