This study was conducted to exhibit the importance of kermes oak (Quercus coccifera L.) and mock privet (Phillyrea latifolia L.) in the grazing system and animal feeding. For this purpose, the leaves of these two evergreen shrubs were harvested by hand-clipping in their early vegetative stages at Şarköy, Tekirdağ, Turkey, in April 2019. The nutrient and mineral contents and in vitro digestibility of kermes oak and mock privet was determined by using in vitro gas production technique
