these sires the annual milk production for eight of their daughters were
recorded.

several years. While this data set consists of observed milk production for
40 cows, the SireHerd data has 24 observations. SireHerd contains
information of what herd the cows belong to. sires and SireHerd do not
contain the same observations.
