Abstract：
Identifying the potential presence of stress at the pig farm is fundamental since it affects pig welfare. As a result, a reliable and straightforward tool to monitor stress could record the welfare status of the animals. Although numerous methods to assess the welfare of pigs have been developed in the past, no gold standard has been established yet. Recently, the value of saliva as a tool to identify chronic stress in piglets was explored, as it can be collected fast and non-invasively. Since the protein composition, i.e., the proteome of porcine saliva, responds to stress, the affected proteins could be used as salivary stress biomarkers. The present review first defines stress and its relationship with welfare. Next, the porcine gland-specific salivary proteome is characterized. Finally, six potential salivary biomarkers for stress are proposed, i.e., odorant-binding protein, vomeromodulin-like protein, chitinase, lipocalin-1, long palate lung and nasal epithelium protein, and alpha-2-HS-glycoprotein.
摘要：
确定养猪场潜在的压力是至关重要的，因为它会影响猪的福利。因此,一个可靠和直接的工具来监测压力可以记录动物的福利状况。尽管过去已经开发了许多评估猪福利的方法，尚未建立黄金标准。最近,探索了唾液作为识别仔猪慢性应激的工具的价值，因为它可以快速和非侵入性地收集。由于蛋白质组成，即，猪唾液的蛋白质组，对压力的反应，受影响的蛋白质可用作唾液应激生物标志物.本综述首先定义了压力及其与福利的关系。接下来,猪腺体特异性唾液蛋白质组的特征。最后,提出了六种潜在的唾液压力生物标志物，即，气味结合蛋白，精子调节蛋白样蛋白,几丁质酶，脂质运载蛋白-1，长腭肺和鼻上皮蛋白，和α-2-HS-糖蛋白.
