Poultry calculators

Henlytics poultry calculators are free tools that work out a farm planning number from your own figures, with the method shown under the result. They work out how many days of feed are left in a silo and how much heat stress the house conditions put on market-size broilers.

  • Days of feed left calculator

    Works out how many days a feed silo will last and the last day to order, including intake that rises as the flock grows.

    You enter
    Silo capacity, how full it is, birds fed and feed per bird per day. Daily increase in intake and delivery lead time are optional.
    You get
    Kilograms of feed in the silo, feed used today, days of feed left, the run-out date and the last day to order.

  • Heat stress calculator for broilers

    Estimates heat stress in market-size broilers from house conditions, with the temperature-humidity-velocity index published by Tao and Xin (2003).

    You enter
    Air temperature, relative humidity and air speed at bird level, in °C or °F and m/s or ft/min.
    You get
    The index, the wet bulb temperature, and the stress state the study links to it after 90 and 120 minutes.
