Characteristics of litters from which the high and low gilts were selected and reproductive characteristics of the selected low and high BW gilts used in the study.

The following characteristics of litters used for gilt selection are presented: average litter birth weight (BW) in which selected gilts were born (kg), the mean BW of selected gilts (kg), the mean litter size and average parity of dams, as well as calculated Z-scores controlling for total born litter size and parity. Reproductive characteristics of low and high BW gilts are presented as: mean ovulation rate (counts of corpora lutea (CL)), mean ovarian weights and summed weights of all CLs (g) and mean litter size including alive, dead and mummified (inspissated fetuses with CRL <20 cm) fetuses.
