This research was carried out to determine the silage characters of some Italian ryegrass varieties. 21 Italian ryegrass varieties (Master, Quickston, Big Boss, Koga, Venüs, Braulio, Jivet, Medoacus, Excellent, Tornado, İlkadım, Caramba, Kartetra, Efe-82, Trinova, Hellen, Devis, Vallivert, Teanna, Rambo, Zeybek-19) were used as materials. The trial was conducted in the 2022-2023 growing season on land belonging to the Agricultural Ar&Ge Center of Sivas Science and Technology University, Faculty of Agricultural Sciences and Technology. Harvesting for silage making was done when the grains on the ears reached the milking stage, silage samples were placed in 2 kg plastic vacuum bags, and the bags were opened after 60 days for analysis. As a result of the analysis, it was determined that the acid detergent fiber (ADF) rates in silage varied between 31.09-36.74%, neutral detergent fiber (NDF) rates varied between 52.56-61.75%, crude protein rates varied between 9.76-12.34%, crude ash rates varied between 8.23-12.01%, dry matter rates varied between 21.27-29.90%, pH values varied between 4.46-5.90, dry matter digestibility rates varied between 60.28-64.68%, dry matter intake rates varied between 1.95-2.28% and the relative feed value varied between 90.9-113.6, depending on the Italian ryegrass varieties. Among the Italian ryegrass varieties examined in the research, Koga and Vallivert varieties, which have low acid detergent fiber and neutral detergent fiber rates, high dry matter digestibility and dry matter intake rates, and relative feed value, stand out and it is suggested that these varieties can be grown in Sivas and similar ecologies for silage purposes.
