Breeding Trait Option Definitions

Breeding Trait Option Definitions

Many of the StockMate Breeding Traits have dropdown options that are a list of numerical numbers that have industry meaning. The source and definitions for the values are provided here, to be used as guidelines.
However, if your operation has different definitions for the values this is completely acceptable and results can be interpreted as required on a company basis.
