How to Use This Calculator
  1. Enter the number of animals and daily hay intake in pounds per head.
  2. Set the feeding period in days to cover (e.g., 150 days for a typical winter feeding period).
  3. Input hay bale weight (round or square) and storage shrink/waste percentage.
  4. Review the total bales needed and recommended storage capacity in tons.
  5. Order 10-15% more hay than calculated to buffer against weather delays and quality variation.

What each input means

Head Count
Number of animals to feed during the storage period.
Daily Consumption per Head
Pounds of hay consumed per animal per day (cattle avg 25-30 lbs).
Feeding Days
Number of days hay will be fed (typical winter feeding: 120-180 days).
Waste Factor
Expected hay waste percentage from feeding method and storage losses (ring feeder ~10-15%, ground feeding ~25-35%).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Head Count = 30, Daily Consumption per Head = 25, Feeding Days = 150, Waste Factor = 15 = 4 input(s) provided
  2. Calculate Total Hay Needed
    Total Hay Needed
    64.7 = 64.7
  3. Calculate Round Bales
    Round Bales
    130 = 130
  4. Calculate Total Pounds
    129375 = 129375
  5. Calculate Small Bales
    Small Bales
    2588 = 2588
