LSCS, lactation averages of somatic cell score; G, additive genetic variance; HY, herd-year class; E, residual variance.

¹LSCS_{1 to 5}, lactation average somatic cell score traits for 1st to 5th parity.

Variance estimates corresponded to single-trait and multiple-trait analyses using animal and sire models, respectively.
