Determination of the effect of different cutting times on the forage yield and quality of Kediyünü village rangelands in Uşak province

This study was conducted to determine the changes in yield and quality of pasture during the grazing season of a natural pasture in Kediyünü village of Usak province center. The experiment was established in a randomised complete block design with three replications. In the research, 50 square meters of covered areas were established in 3 different regions representing pasture area. Starting from May 5, three samples were taken from the ungrazed areas, every 15 days during the grazing season, with one square meter of quadrat. The green yield, hay yield, dry matter ratio, crude protein (CP) ratio, CP yield, acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN) and relative feed value (RFV) were determined in this research. According to results of this research, the highest yield of green and hay yields were determined on 5 June, while the lowest yields were obtained on 5 July. Crude protein yield increased until May 20, then began to decrease. During the grazing season, crude protein content, total digestible nutrients and relative feed value decreased, while ADF and NDF values increased.
