Effects of forage particle size, hydraulic press pressure and pressure dwell time on durability and particles abscission of complete feed blocks

In order to determine the effects of hydraulic press pressure in the complete feed blocks (CFBs) machinery, with the pressure dwell time and forage particle size on durability, particles abscissionand storage of blocks using a completely randomized design (12 treatments and 10 replications)with factorial arrangement current experiment was conducted. The factors were: two levels of 200 and 220 bar hydraulic pressures in CFB machinery, three levels of 5, 17 and 30 sec dwell time along with two particle sizes (alfalfa hay and wheat straw) of short (average 10 mm) and long (average 30 mm) using forage to concentrate ratio of 45:55. Complete feed blocks with long or short particles with press pressure of 220 bar and dwell time of 30 sec had higher durability andCFBs with long or short particles with press pressure of 220 bar and dwell time of 17 sec had minimum and maximum of particles abscission, respectively (P
