Tolerance models

AuctionsPlus are updating our User Agreement and Sale Terms. 

The information outlined in this article is effective as of the 1st March, 2023.

AuctionsPlus recognise that defining tolerances across a wider range of traits on the assessment allows everyone to move forward with more clarity on how to resolve an issue when it arises.

Lines of stock which are assessed to be uniform and consistent for a trait, are not permitted a tolerance outside of how they are assessed. Whereas lines which vary more from animal to animal, especially for subjective traits, have a tolerance which applies to the assessment as a greater variance is expected within the mob.

  • If a mob is assessed to fit 100% within a trait (single descriptor), there will be a nil tolerance on that trait. 
    For example: a line of cattle are assessed to be 100% Angus/Angus. A valid claim would exist if any cattle delivered were of a different breed.
  • Model 1
    If multiple descriptors are used to assess breed, bloodline or age, the number of head delivered must fit exactly with the number assessed (nil tolerance)
    For example: a line of sheep are assessed to be 30% Merino / 70% Border Leicester. A valid claim would exist if any sheep delivered did not meet this breed description
  • Model 2
    If multiple descriptors are used to assess horn status, crutching or sex, the number of head delivered must fit within the assessed descriptors; but has a 10% tolerance within those descriptors. There is a nil tolerance on any number of head that do not match the descriptors used.
    For example: a line of 100 cattle are assessed to be 50 polled and 50 dehorned. A valid claim would exist if, for example, 3 head were horned and 57 were dehorned.
  • Model 3
    If multiple descriptors are used on temperament, muscle score, wrinkle score, seed and burr, hip/ wither height (frame), dentition, fat score, breeding quality, carcase quality, wool length or mulesing; 80% of the number of head delivered must fit within the assessed descriptors and no more than 10% or an equal number to the adjacent descriptor, whichever is lower, may fall into the adjacent descriptors. No animal can be more than 2 descriptors away from the originally assessed descriptors.
    For example: a line of 500 sheep are assessed for Breeding Quality to be 70% Good & 30% Very Good. A valid claim would exist if, for example, 55 head were fair and 2 head were plain

[1] However, if progeny is weaned and its Bloodline or registered sire/dam details are incorrect then, the Buyer may reject the progeny only and not the dam (assuming the dam is correctly described). If progeny is unweaned and its Bloodline or registered sire/dam details are incorrect then, the Buyer may reject the progeny and the dam.
