    Summary
    This summary is machine-generated.

    Young pheasants drink more water, with intake decreasing as they age. Dietary protein significantly impacts water consumption, while temperature and salt have minimal effects on pheasant hydration needs.

    Area of Science:

    • Animal Science
    • Avian Physiology
    • Poultry Nutrition

    Background:

    • Understanding water intake is crucial for optimal pheasant growth and health.
    • Factors influencing water consumption in game birds require detailed investigation for effective management.

    Purpose of the Study:

    • To quantify daily water consumption in pheasants across different ages.
    • To assess the impact of environmental temperature, dietary protein, and salt levels on pheasant water intake.
    • To compare water consumption patterns between intermittent and ad libitum feeding schedules.

    Main Methods:

    • Water intake was measured in pheasants from three to 12 weeks of age.
    • Experiments involved controlled variations in ambient temperature (10-25°C), dietary protein, and salt concentration.

  • Consumption patterns were compared between pheasants fed three times daily versus those fed ad libitum.

    • Main Results:

    • Water consumption decreased from 240 ml/kg at three weeks to 80 ml/kg at 12 weeks of age.
    • Temperature variations (10-25°C) had minimal effect on water intake.
    • Increased dietary protein led to higher water consumption, while a doubled salt level caused only a 14% increase.
    • Total daily water intake was similar between feeding groups, but consumption patterns differed significantly.

    Conclusions:

    • Age is a primary determinant of water intake in pheasants, with younger birds consuming more.
    • Dietary protein is a key factor influencing hydration, whereas temperature and salt have limited impact.
    • Feeding schedules affect the timing but not the total volume of daily water consumption in pheasants.
