Domask Rose residue is an available by-product, remained after extraction processing of rose flower in some parts of Iran, which constitutes a potential environmental pollutant and cost effective for disposal. This experiment was conducted to determine the chemical composition and ensiling potential of this by-product. The residue was collected from processing plants around Kashan area, central region of rose industry, and analysed chemically. Using a completely randomized design, the collected substance was ensiled, together with different amounts of effluent absorbents such as wheat straw, dry shredded beet pulp, wheat bran and limestone powder, to provide optimum dry matter and ensiling conditions. The materials were completely mixed and ensiled in 40 sealed plastic containers (6 liters volume), including 10 treatments and 4 replicates. After one month, all containers were opened and silage characteristics evaluated.The OM, CP, CF, EE, NFE, of Rose residue were 94.4, 11, 24, 2.4 and 57.3 percent in dry mater (DM) respectively and GE was 4525 cal / g of DM. The DM content of silages varied from 26.7 to 36.6 percent, which was significantly (p0.05) different among the treatments. the values of pH were varied between 4.08 and 4.36 and significant (p0.05) differences were observed among the treatments. The treatments contained rose residue, sugar beet shredded and limestone 79, 20 and 1 percent respectively or Rose residue, sugar beet shredded, wheat straw and limestone 79, 10, 10 and 1 percent respectively, had optimised DM and lower pH, which were considered as good quality silages.
