Estimating the individual stillborn rate from easy-to-collect sow data on farm: an application of the bayesian network model

Table 2 Discretisation of variables used in the model

Variables measured	Categories used
Parity rank	= 0 and 1 (Gilts and parity 2) = 2 and 3 (Parities 3 and 4) = 4 and more (Parities 5 and more)
TB_n−1	TB_n−1 ≤ 14 piglets 14 < TB_n−1 ≤ 18 piglets TB_n−1 > 18 piglets
%S_n−1	%S_n−1 ≤ 8% 8% < %S_n−1 ≤ 15% %S_n−1 > 15%
BFT before farrowing	BFT ≤ 15 mm BFT > 15 mm

TB_n−1: number of total born at previous farrowing, %S_n−1: stillborn rates at previous farrowing, BFT: backfat thickness.
