Additionally, the probability to receive
medication around parturition increased with the duration
of gestation (χ2
1,50 = 4.1, P = 0.004) and the duration of
floor heating before delivery (χ2
1,50 = 7.3, P = 0.007);
this may reflect that 1 main reason for medication around
parturition is related to farrowing problems, including a
delayed onset of farrowing.
