Abstract

This work shows that the botanical composition of the meadows studied according to the region and that the grass family is less well represented in R.Souk (13%) and Ain Khiar (14%) than in Oued El-Hout (18%). The Ain-Khiar region is dominated by leuminous plants (43%). Thus, all the grasslands studied do not follow the laws classically described for grasslands, namely the dominance of grasses followed by legumes. Differences were observed between the chemical compositions of grasslands. The Ain-Khiar region is distinguished in particular by higher average contents of mineral matter (24.6% DM) and crude protein (14.32% DM).
