Özet:  In this study, it was aimed to determine the chemical composition, gas production, methane production, organic matter digestibility and metabolisable energy values of some root and tuber crops obtained from markets. Potatoe, carrot, sugar beet, sweet potatoe, turnip, black carrot, radish and jerusalem artichoke obtained from the markets found in Kahramanmaraş province were used as study materials. Dry matter (DM), crude ash (CA), crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), ether extract (EE) analysis were performed on the collected materials and afterwards gas production values metabolic energy contents and organic matter digestibilities of study materials were calculated. The CA, DM, ADF, NDF, EE and HP of root and tuber crop wastes varied between 0.66 and 2.41 %, 7.36 and 21.60 %, 4.52 and 16.27 %, 12.58 and 34.30 %, 0.87 and 2.41 % and 5.11 and 19.01 % respectively. The net gas production of wastes varied between 65.74 and 84.66 ml. The metabolisable energy values of study materials ranged from 11.86 to 14.07 MJ kg-1 DM. The net methane production varied between 8.29 ml to 11.49 ml. The percentage of methane production ranged from 11.56 to 14.89 %. The OMD of root and tuber crop wastes ranged from 79.69 to 93.66 %. In this study, it is considered that the materials classified as waste may be evaluated in animal nutrition. However, it is thought that due to the chemical compounds contained in the waste material, the amount of use should be considered. It is also stated that there will be positive effects on the prevention of environmental pollution and waste.
