This study evaluated the effect 3 types of conditioning (Untreated, Impeller, Roller) and the number of times for tedding (rake-teder) performed in one day on the drying rate of tall fescure hay. The experiment was performed at The forage site of Cheonan-si seongwhan-eup National Institute of Animal Sciencee. It took 3 days to make tall fescue hay. The Impeller and Roller conditioning types shortened the haymaking period by 1 day compared to untreated hay. Impeller and roller samples had less than 20% of water content by the 23rd-day at 13 o'clock. Tedding frequency failed to affect haymaking. There was no correlation between the three types of conditioning or tedding frequency and acid digestible fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDF), crude protein (CP), or relative feed value (RFV) in tall fescue hay. CP was 12.5~12.9% for the three types of conditioner with 1 or 2 times of tedding a day, Threrfore, conditioner types and gedding frequency had no significant effect on CP.
