  1. Base: reference breeding scheme with complete phenotyping and a 2-years generation interval on both the dam and the sire path. Alt: accelerated breeding scheme in which only the early trait is phenotyped on potential dams, while potential sires are also phenotyped on the late trait. This partial phenotyping of the dams enables halving the dam generation interval to 1 year.
