Standardized ileal digestibility of amino acids in pistachio blanks and soybean meal fed to growing pigs

Pistachio blanks are coproducts of pistachio processing and are discarded due to their hollow shells or immature nuts, which make them unusable as human food. Pistachio blanks float in water and the annual production is estimated to be between 50,000 and 70,000 metric tons. A similar coproduct, pistachio shell powder, was recently demonstrated to provide significant amounts of energy in diets for sows. However, there is no information about the digestibility of amino acids (AA) in pistachio blanks when fed to pigs. Although AA concentration in pistachio blanks is low, there is a need for determining standardized ileal digestibility (SID) of AA in pistachio blanks. Therefore, an experiment was conducted to test the hypothesis that the SID of AA in pistachio blanks are comparable to those in soybean meal (SBM) when fed to growing pigs.

Impact of soybean oil on net energy and nitrogen balance in group-housed pigs allowed ad libitum access to feed

Diets for pigs may vary in composition and in their concentration of the energy containing nutrients (i.e., protein, fat, starch and sugars, and dietary fiber). To our knowledge, however, there is no information on how concentration of net energy (NE) is affected by dietary fat concentrations in diets fed to group-housed pigs. Therefore, the objective of this experiment is to test the hypothesis that increased soybean oil in diets for group-housed growing pigs will increase NE and nitrogen balance.

Determination of net energy and nitrogen balance in group-housed pigs fed diets containing varying levels of starch and fiber

Diets for pigs may vary in composition and in their concentration of the energy containing nutrients (i.e., protein, fat, starch and sugars, and dietary fiber). To our knowledge, however, there is no information on how concentration of net energy (NE) is affected by dietary starch and fiber concentrations in diets fed to group-housed pigs. Therefore, the objective of this experiment is to determine NE and nitrogen balance in diets containing various levels of starch and fiber fed to group-housed pigs.
