context: Lean sows syndrome (CXS) is a behavior observed in stall sows, similar to AA, in which some sows are extremely active after early pregnancy, eat little and become depleted, which often leads to death. They suffer from emaciation, hypothermia, poor appetite, anxiety and hyperactivity [3]. The syndrome can mainly be associated with social and environmental stress factors. Stress in sows is often perceived as a consequence of animal restriction that occurs during intensive production. The sows that suffer most from the constraining conditions are those who are breastfeeding or pregnant because they have very little room for movement, because they are kept in fenced boxes for pregnant women or tied up to 16 weeks of pregnancy, which violates the natural and social behavior. However, increased movement and freedom are also stressful for adult sows, which usually occurs after weaning. When they unite in groups, they vigorously battle one emerging dominant sow that eats insatiable. It also happens that two subordinate sows are part of a group that actively avoids competitive feeding situations and mock the dominant sow. Affected sows have poor appetite, but often exhibit picacism, excessive water intake (polydipsia), and anemia.
