Abstract :This study was carried out to determine change in botanical composition, nutrient content, feed value and some quality parameters of natural grasslands in Ankara, for 4 months May, June, July and August. The study was carried out in the natural rangeland areas of 3 villages within the borders of Ayaş insert ignore into journalissuearticles values(1 and 2); and Nallıhan insert ignore into journalissuearticles values(3); in Ankara province in 2016. The botanical composition, nutrient contents fibrous materials, mineral substances, with In vitro gas production: GP, dry matter digestibility: DMD, and organic matter digestibility: OMD, energy values, and methane production:MP capacities, in vitro neutral detergent fiber digestibility: dNDF, relative feed values: RFV and relative forage quality index:RFQI determined by taking feed samples every 15 days in May, June, July and August. The botanical diversity of rangelands was found different from each other. The proportion of legumes compared to weight in rangeland 1 was higher compared to grassland 2 and 3, and the proportion of the wheatgrain and others was lower. While wheatgrain and legumes ratio was close to each other on rangeland 2, the proportion of cereals was found higher than legumes on the rangeland 3. In all three rangelands, while the CP, NFE, N, Ca, GP, DMD, OMD, dNDF and RFV RFQI values of the plants were high in May, it was determined that these features decreased significantly until August insert ignore into journalissuearticles values(P<0.05);. CF and ADF, NDF and ADL contents, were low in May, but increased significantly towards August insert ignore into journalissuearticles values(P<0.05);. Ash content was higher in August and July than in May and June insert ignore into journalissuearticles values(P<0.05);. While MP in rangeland 1 and 2 was high in May, June and July, and low in August insert ignore into journalissuearticles values(P <0.05);, but in rangeland 3 was highest in May compared to other months insert ignore into journalissuearticles values(P<0.05);. RFV and forage quality of plants in rangeland were highest in rangeland 1 followed by 2 and han rangeland 3. Angora goats can be grazed easily in May and June.
