为了提高母猪的整体福利水平，并降低35天哺乳后期的压力水平，我们选择了可能与压力相关的有针对性的行为指标。因此，我们监测和评价了两个不同品种母猪对分娩环境的适应能力。本研究选用大民母猪（大白色×民猪母猪，n = 20）和大白色母猪（n = 20），分栏分娩。分别于产后20、27和34 d进行促肾上腺皮质激素（ACTH）刺激试验后-15 min、+15、30、60、90、120、180和240 min采集唾液测定皮质醇浓度。于产后第3 ~ 5周每周第7天的07：00 ~ 09：00和13：00 ~ 15：00通过视频观察产妇腹卧、侧卧、排便、排尿、假咀嚼和咬棒行为。观察行为后测定唾液中白细胞介素（IL）-6、肿瘤坏死因子（TNF）-α和分泌型免疫球蛋白（SIgA）的含量。结果表明，大敏母猪和大白色母猪在3周龄时的行为表现无显著差异。此外，在腹卧和咬栏行为方面，大民母猪和大白色母猪之间没有显著差异，除了侧卧到其他姿势，假咀嚼，排便和排尿在第5周。4周龄时两品种间腹卧位差异显著。ACTH测定结果表明，大敏母猪和大白色母猪在产后27、34天的ACTH含量差异极显著（P<0.01）。此外，产后3周时，两品种间血清IL-6和TNF-α水平差异不显著。但在产后5周，这些指标差异有统计学意义（P = 0.000和P = 0.003）。产后3周唾液中SIgA含量在品种间差异极显著（P<0.01）。总之，两种母猪在产后4周后可能都处于应激状态。然而，在适应这种分娩环境方面，大民母猪可能比大白色母猪更好。
To improve the overall welfare levels of sows and to reduce stress levels at late 35-day lactation, we selected targeted behavioral indicators that might be associated with stress. Therefore, we monitored and evaluated the adaptive capability of two different breeds of sows to the farrowing environment. In this study, Damin sows (Large White × Min pig sows, n = 20) and Large White sows (n = 20) were farrowed in individual pens. Saliva was collected and tested for cortisol density at –15 min, and then at +15, 30, 60, 90, 120, 180 and 240 min after an adrenocorticotropic hormone (ACTH) stimulation test conducted at 20, 27 and 34 d post-partum. The postures, including ventral and lateral recumbency to other postures, defecating, urinating, sham-chewing and bar-biting behavior, were observed by video from 07:00 to 09:00 and from 13:00 to 15:00 on the 7th day of each week from the 3rd to the 5th week post-parturition. In addition, the concentrations of salivary interleukin (IL)-6, tumor necrosis factor (TNF)-α and secretory immunoglobulin (SIgA) were assayed after the observed behaviors. The results showed no significant difference between Damin sows and Large White sows in terms of behaviors at the 3rd week. Additionally, there were no significant differences between Damin and Large White sows in terms of the behaviors of ventral recumbency and bar-biting with the exception of lateral recumbency to other postures, sham-chewing, defecation and urination in the fifth week. Meanwhlie, there was significant difference between two breeds in term of ventral recumbency at the 4th week. The result of the ACTH test showed a significant difference between the Damin and Large White sows by the 27th and 34th days postpartum (P<0.01). In addition, the serological concentrations of IL-6 and TNF-α were not significantly different between the two breeds at the 3rd week postpartum. However, these indicators were significantly different at the 5th week postpartum (P = 0.000, and P = 0.003, respectively). The SIgA concentrations in saliva were significantly different between breeds at the 3rd week postpartum (P<0.01). In conclusion, both breeds of sows maybe in a state of stress after the 4th week postpartum. However, the Damin sows may be better than the Large White sows in terms of adapting to this farrowing environment.
