  ped,
  minParentAge = 3,
  maxOffspringAge = NULL,

Details

Description of how Production and Production Status (color) is calculated.

  1. The Production Status is calculated on September 09, 2019, Births = count of all animals in group born since January 1, 2017 through December 31, 2018, that lived at least 30 days.

  2. Dams = count of all females in group that have a birth date on or prior to September 09, 2016.

  3. Production = Births / Dams

  4. Production Status (color)

    1. Shelter and pens

      1. Production < 0.6; Red

      2. Production >= 0.6 and Production <= 0.63; Yellow

      3. Production > 0.63; Green

    2. Corrals

      1. Production < 0.5; Red

      2. Production >= 0.5 and Production <= 0.53; Yellow

      3. Production > 0.53; Green

This code may need to be modified to allow the user to supply a list of IDs to include as group members. Currently each animal in the provided pedigree (ped) is considered to be a member of the group.
