Abstract :In this study, it was aimed to evaluate the nutrient content, gas production, methane production, metabolisable energy, and organic matter digestibility of some fruit residues obtained from markets. Lemon, orange, tangerine, apple, melon, watermelon, pomegranate, and pear were used as study materials. On the collected materials, crude ash insert ignore into journalissuearticles values(CA);, dry matter insert ignore into journalissuearticles values(DM);, acid detergent fiber insert ignore into journalissuearticles values(ADF);, neutral detergent fiber insert ignore into journalissuearticles values(NDF);, ether extract insert ignore into journalissuearticles values(EE);, and crude protein insert ignore into journalissuearticles values(CP); analysis were performed; gas production insert ignore into journalissuearticles values(GP); values were found; and metabolic energy insert ignore into journalissuearticles values(ME); contents and organic matter digestibility insert ignore into journalissuearticles values(OMD); degrees of residues were calculated depending on these values. The species significantly insert ignore into journalissuearticles values(P<0.001); affected the nutrient content and GP values of residues. The CA, DM, ADF, NDF, EE, and CP of fruit residues varied between 0.44 and 0.99%, 6.81 and 25.65%, 5.02 and 16.75%, 8.15 and 21.04%, 3.32 and 12.55%, and 1.81 and 10.89%, respectively. The GP, net methane, percentage of methane, ME, and OMD of residues varied between 61.22 and 90.95 ml, 6.93 to 11.04 ml, 10.96 to 12.92%, 10.91 to 14.92 mj kg-1 DM, and 72.62 to 98.96%, respectively. Based on the findings obtained as a result of the study, it is understood that these residues can be a good feed source for ruminant animals, but it is thought that studies on the use of these water-rich residues by both the drying method and silage with other feed materials should continue. Considering its anti-methanogenic properties, pomegranate residues were close to this potential but were not found at the desired level. By using these residues, which are seen as garbage, in animal nutrition, environmental pollution will be prevented.
