Abstract: This experiment was conducted to determine the differences between apple pomaces, obtained from puree and juice making. The chemical composition, rumen degradation characteristics, in vitro digestibility and gas production of 2 apple pomaces were determined. The dry matter (DM), neutral detergent fiber (NDF) and non fiber carbohydrates (NFC) of apple pomace from puree making and apple pomace from juice making were 185, 413.8 and 426.65 g kg 1 DM and 201.7, 567.9 and 281.45 g kg 1 DM, respectively. Apple pomace from puree making had higher soluble (43.62 vs 30.55 %) (p<0.05) and lower degradable (51.87 vs 67.43 %) (p<0.05) DM fractions. Rate of degradation was also higher in apple pomace from puree making (0.085 vs 0.05). (65.01 vs 55.01 and 63.80 vs 52.99) (p<0.05), respectively. Pomace obtained from puree making had higher in vitro DM and OM digestibility (65.01 vs 55.01 and 63.80 vs 52.99) (p<0.05), respectively. It is concluded that differences between apple processing (puree making or juice making) resulted in, 2 apple pomaces be very different in chemical composition (especially NFC), digestibility and rumen degradation.
