Table 1 Effects of the means of death (found dead vs. euthanized) on characteristics of the animals and pre-mortem circumstances in 65 sows found dead or euthanized on 15 Finnish farms

From: Pathological findings in spontaneously dead and euthanized sows – a descriptive study

  Found dead, n = 27 Euthanized, n = 38 Test and significance
Parity, median (min–max) 2 (0–9) 3 (0–10) p > 0.1, T-test

Body condition score, average (std. dev.) 2.9 (0.79) 2.5 (0.92) p = 0.047 T-test
Weight, average (std. dev.) 244 kg (52.8, n = 24) 219 kg (52.4, n = 28) p > 0.1, T-test
