Abstract: Abstract: An experiment was conducted to investigate the influence of different drinkers and water pressure on water consumption and wastage by nursery pigs in summer. In the experiment, water consumption and wastage were recorded in minute over 5 d. Period 1 compared water consumption and wastage between bowl and swing drinkers at water pressures of 0.10, 0.15 and 0.20 MPa with 10 pigs (body weight 6.1-20.1 kg) in each pen. Period 2 compared water consumption and wastage between swing drinkers with blades and standard swing drinkers at water pressure of 0.10 MPa with 5 pigs (body weight 17.5-24.6 kg) in each pen. Water consumption of each pig from the bowl drinker at water pressures of 0.1, 0.15 and 0.20 MPa was 16.2±3.0, 30.3±8.1 and 38.3± 4.8 L/d; and from the swing drinker was 5.7±1.0, 8.7±1.9 and 10.3± 0.4 L/d, respectively. Predicted wastage/consumption from the bowl drinker at water pressures of 0.1, 0.15 and 0.20 MPa was 83.3%, 85.1% and 85.4%, respectively. Wastage/consumption from the swing drinker at water pressures of 0.1, 0.15 and 0.20 MPa was 54.4%, 48.3% and 45.6%, respectively. Water consumption from swing drinker with blades was not significantly higher (11.3±1.7 L/d) than from standard swing drinker (9.4±1.0 L/d). Wastage/consumption from swing drinker with blades (60.2%) was higher than from standard swing drinker (46.8%). Therefore, to reduce water consumption and wastage, water flow rate should be regulated. In summer, the bowl drinker can lead to more water consumption and wastage than the swing drinker. Swing drinker with blades was not better than the standard swing drinker to reduce water wastage.
