Table 4 Some examples of salivary total esterase activity (TEA), butyrylcholinesterase (BChE) and lipase response after different stressful stimuli
Stressful condition | Reference | Animals | Sample size | Sampling times | Â | Results (UI/L, unless indicated, median values are expressed) | Comment |
|---|---|---|---|---|---|---|---|
Transport and lairage to slaughterhouse | López-Arjona et al. [38] | Female at end-fattening period (5–6 months) LargeWhite x Pietrain | 45 | Before, immediately after and at 4 h from transport | TEA (IU/L) | • Before transport:151.7 • Just after: 190.6 • After 4 h: 277.8 |  |
Disease (lameness and rectal prolapse) | Contreras-Aguilar et al. [27] | Male mid fattening period (60–90 days) (Large White) | 60 | Just only one sampling | TEA (IU/L) | • Healthy: 128.8 • Lame: 293.2 • Prolapsed: 780 |  |
2 min snaring | Tecles et al. [30] | Male growing pigs (Large White × Landrace × Duroc) | 20 | Before, just after and at 15 min after the stress | TEA | 1.49-fold increase just after stress | Returned to basal values at 15 min |
Lipase | 1.60-fold increase at 15 min after stress | No increase just after stress | |||||
Tecles et al. [32] | BChE (nmol/min/mL) | 5.25-fold increase just after stress | Still increased at 15 min |
