    Sow body condition caliper is the new tool for body condition assessment in order yo aid feeding decisions decidions during gestation. The aim of this research was to examine the accuracy of sow body condition caliper, compared visual body condition and backfat thickness measurements, in multiparous sows under commercial conditions. The total 561 crossbred sows between Landrace and Large White form five farrowing groups were randomly divided into three groups separated by assessing methods include 1.visually scoring, 2.measured backfat thickness at P2 position whit lean meter, and 3.caliper.  Sows were fed according to body condition based on each method.
