400 Day Weight EBVs are estimates of genetic differences between animals in live weight at 400 days of age.
400 Day Weight EBVs are calculated from the live weight performance of animals when they are between 301 and 500 days of age, and/or genomic information, and are expressed in kilogram units.
Higher 400 Day Weight EBVs indicate the animal is expected to produce progeny with heavier live weights at 400 days of age.
