Animals | Breed | Sample size | Method | Cortisol mean values (μg/L) | Commentary | Reference |
|---|---|---|---|---|---|---|
Finishing pigs (165 days old, ~ 100 kg) | Duroc x [Landrace x LargeWhite] | 20 | Immuno-chemiluminescence | 2.4–7.0 |  | Escribano et al. [10] |
Growing pigs (~ 105 days old, ~ 88 ± 8 kg) | • Duroc × [Landrace × Large White] • L62 (a crossed of several genotypes) × [Landrace × Large White] • Pietrain × [Landrace × Large White] | 12 samples from ropes (10–12 animals per rope) | Liquid chromatography–tandem mass spectrometry | • 1.20 ± 0.20 • 0.51 ± 0.05 • 0.74 ± 0.30 | No individual samples were measured, but 12 rope samples from 4 different farms (3 ropes per farm) | Rey-Salgueiro et al. [12] |
Nulliparous non-pregnant gilts (8–9 months old, ~ 150–170 kg) | Large White × Landrace | 91 | Radio immunoassay | 0.8–2.2 | Samples correspond to 8 gilts repeatedly sampled at different days | Merlot et al. [5] |
