Litter assessment on the boar data sheet

Boars with more than 10 litters are identified with stars (*) for their scores in the categories vitality, uniformity and weight.


  • Boars with an average of up to -2 standard deviations (*)
  • Boars with an average of up to + 2 standard deviations (**)
  • Boars with more than 2 standard deviations above average (***)


Boars with only one star in the overall result are culled.

Every boar is tested!

Litter quality in the model is calculated based on the effects of the farm and litter number and the total number of piglets born in the litter.

The results for each individual boar are published once 10 or more litters of a boar are evaluated.
