This study was conducted to determine the effect of wet sugar beet pulp (WSBP) ensiled separately or with apple (SBA), lemon (SBL), mandarin (SBM), orange (SBO) and peaches (SBP) pulps at the half rate (50:50) on the silage pH, quality, fleig point, chemical composition, metabolizable energy (ME), net energy lactation (NEL) and organic matter digestibility (OMD). The pH of the PPS group was significantly higher and fleig points lower than the other groups (p<0.05). While dry matter content was highest in the WSBP group lowest values were obtained from SBL and SBM groups (p<0.05). The crude fiber (HS) and acid detergent lignin (ADL) contents were not significant among the groups. The chemical composition and cell wall components of the treatment groups were significantly different among the groups (p<0.05). However, crude ash in the SBP group and neutral detergent fiber (NDF) values significantly higher than those of other groups, however, crude fat and crude protein values were lower than those of other groups. In the WSBP, SBO and SBP groups the metabolic energy values were significantly higher than those of SBM and SBL groups. In the SBO the NEL value were higher than those of SBA, SBL and SBM groups; in the SBO groups’ OMD value was higher than those of SBA, SBL and SBM groups (p <0.05). When quality classes considered, SBA and SBO groups ranked as “good quality”; WSBP, SBL and SBM groups ranked as “satisfactory”; and SBP group ranked as “middle quality”. As a result, WSBP can be ensiled with fruit pomace and particularly apple and orange pulps can be used with sugar beet pulp to get better quality silages.
