In this study, it was aimed to determine the effect of substitution of barley with the different amounts of dried white mulberry pomace (DWMP) and dried red mulberry pomace (DRMP) on in vitro true digestibility (IVTD) values. The mixtures were formed as: barley (100%), DWMP (100%), DRMP (100%), barley+DWMP (75%+25%), barley+DWMP (50%+50%), barley+DWMP (25%+75%), barley+DRMP (75%+25%), barley+DRMP (50%+50%), barley+DRMP (25%+75%). There were no differences for IVTD, in vitro true dry matter digestibility (IVTDMD), and in vitro true organic matter digestibility (IVTOMD) values between barley and barley+DWMP (75%+25%). Although, IVTD, IVTDMD, and IVTOMD values of barley+DWMP (75%+25%) and barley+DWMP (50%+50%) were similar, the same digestibility values of the mixture containing barley+DWMP (50%+50%) were lower (P<0.05) than those of barley. While substitution of barley with DWMP increased (R2=0.7754) in vitro true neutral detergent fiber digestibility (IVTNDFD), substitution of barley with DRMP did not change IVTNDFD. In conclusion, due to nutrient composition and digestibility of DWMP, barley may be substituted with DWMP up to 50% in diets of livestock raised for meat or milk production. Further studies are needed to determine the effects of barley substitution with DWMP on in vivo digestibility, rumen fermentation, fattening performance or milk production.
