Influence of Harvesting on Quality of Alfalfa Forage used for Haylage and Hay

The paper presents the three years efficiency results (2011-2013) of the work and ways of harvesting (three types of  mowers, with or without spreading the forage) influencing the quality of the forage (the content of crude protein and  crude fiber) during the three days drying process. These results indicate that the harvesting method can strongly affect  the work efficiency, energy consumption, the forage drying intensity and the quality of forage used for hay and haylage  preparation. The best quality of the forage was achieved when a drum rotating mower POTTINGER CAT 185 was used.  Negative correlation was found between content of crude protein and the crude fibre content, depending on the type of  mower, varying in the range between r= -0.978 and r= -0.882 (POTTINGER CAT 185 r= -0.882 P≤0.05 to JF STOLL SB 200 r= -0.978 P≤0.001).
