In Ihis study, effects of no additives or 0.5% urea, 5% molasses, and 5% ground wheat grain additives on barley, btead wheat, drum wheat, and Iriticale silage quality and In vitro dry matter digestibility were investigated. Interaction between planl and additives was observed on crude protein (CP) content ol silages (P<0.05) Increment of CP was the highest in 0.5% urea added silages. Addition of urea and ground wheat grain decreased ADF contents of all silages when they were compared with control silage (P<0.05). All the addillves decreased NDF contenl of silages. Interaction between plant and additives was observed on pH values of silages (P<0.05). The highest in vitro dry matter digestibilites were determined in barley silages among fhe planls and wheat grain and molasses among additK/es, respectively (P<0.05). Digestible dry matters obtained from the each unite area were the highest in Iriticale plant and wheal grain added silages.
