    • Week 1: 24 hours of light
    • Week 2: 12-16 hours of light
  14. Intermittent lighting can be used to control
    • reduce feed intake
    • reduce cannibalism
    • reduce egg size
    • reduce power bill
    • "Ascetes"
  15. Foot candle needed to stimulate a chicken
    0.5-1
  16. Too much light will:
    • Power bill increases
    • Cannibalism increases
  17. Control Light intensity by:
    • Correct bulb size
    • Dimmers
  18. Foot candles for people to see birds:
    7 foot candles
  19. Lighting for Replacement pullets
    • Constant light
    • Stepdown-stepup lighting program
  20. Proper lighting methods for poultry
    All artificial light in the morning and let them go to bed with the sunset
  21. Stepdown-stepup lighting programs
    Look at chart in packet
  22. Use of Intermittent Light:
    • 0 to 18 weeks of age: fixed or decreasing
    • 19 to 40 weeks of age: increasing then fixed
    • at 40 weeks of age: on 4:00 off at 4:45 = 12 hours of light
    • at 44 weeks of age: on at 4:00 off at 4:30 on at 42 week on at 5:00 off at 5:30 on at 6:00 off at 6:15 = 8 hours

    • drop .25 every week
    • take sunrise and add 30 mins

  31. Percent Mortality (%)
    • Starting number-Ending number   
    •    Starting number of birds            X100
  32. Percent Hen-Day Production Rate (%)
    Eggs Laid (21-60 Weeks of Age)/ Hen-Days X 100
  33. Percent Hen-Housed Production Rate (%)
    Eggs Laid (21-60 Weeks of age) / Hen housed Days X 100
  34. Eggs Per Pullet Housed (21-60 Weeks)
