Sažetak
The aim of this study was to evaluate the effects of N fertilization on nutritional value of forage from semi-natural grassland, using gas production (GP) technique. The treatments were 35, 100 and 150 kg N ha-1 applied annually. Gas production profiles were fitted to a multiphasic model. Fertilization with 35 kg N ha-1 did not cause changes in fermentation characteristics and organic matter digestibility (OMD) compared with fertilization with 100 and 150 kg N ha-1. Significant differences between years were observed for all GP parameters and OMD (P<0.001). The results indicate that reduction in N fertilization will not induce changes in forage quality regarding in vitro fermentation characteristics and OMD.
