Table 2 Salivary levels of leptin (median, 25th and 75th percentiles; ng/mL) in pigs submitted to different models. A stress model, where samples were taken to 7 pigs before (baseline) and immediately (T0), 15 min (T15) and 30 min (T30) after immobilization with nose-snare. A inflammation model, were samples were taken on 5 pigs before (baseline) and after turpentine injection at 24 h (T24h), 48 h (T48h), 72 h (T72) and 7 days (T7d). A fasting model, where samples were taken to 20 pigs 15 min after of 24 h of fasting and before feeding the animals (T1), immediately (T2) and 90 min (T3) after the food administration. Finally, a growing model where samples were taken to 6 pigs at 60, 90, and 150 days of age
