Abstract

Body reserve mobilization during lactation in first parity sows and its effect on second litter size

The aim of this study was to evaluate the influence of sow body reserves at weaning and body reserve losses during the first lactation on the second litter size (SLS). A number of 1222 females which reached the second parity without failures such as return to estrus after insemination, abortion or failure to farrow, were analyzed. Measurements of body weight (BW), backfat thickness (BT) and body condition score (BCS) were taken within 24 h after farrowing and on the weaning day.
