Relationships between backfat thickness and parameters of reproduction in the Czech Large White sows (short communication)

Čechová, M.; Tvrdoň, Z.

Relationships between backfat thickness and litter performance for individual parities were analyzed on performance-test data under field conditions of 8,285 Large White sows from 39 farms. Backfat thickness measured by ultrasound was corrected for a live weight of 90 kg. Young gilts with a higher backfat thickness achieved higher litter performance and a higher number of litters. Litter size increased from the first until the fifth parity.
