This review analyses the most important types of stress (social, environmental, metabolic, immunological and due to human handling), and their biological consequences for pigs. The physio-pathological changes associated with stress are described, as well as the negative effects of stress on pig production.

2024年1月1日 · In response to a sudden threat (i.e. acute stress), and in correlation with the rapid stress hormone and cardiovascular adaptive responses, pigs show an ‘alarm reaction’, also known as ‘Fight and Flight Syndrome’ or ‘startle response’.

2024年12月10日 · Our study aimed to contribute to the understanding of the stress process in pigs to better assess and control their stress levels. Nowadays, pigs in intensive farming are exposed to several stress factors, such as weaning, transportation, diseases and vaccinations.

Porcine stress syndrome, sometimes called malignant hyperthermia or transport myopathy, is a complex, genetically transmitted myopathy usually triggered by stress or excitement. It also can be triggered by several anesthetics, including halothane, and by depolarizing muscle relaxants.

This study highlights the various stress factors that pigs are exposed to on intensive farms and that affect their health, growth performance and productivity. Therefore, stress biomarkers should be used to monitor and control the stress levels of ...

2013年4月30日 · Pigs experience biological stress such as physiological, environmental, and social challenges when weaned from the sow. The process of weaning is one of the most stressful events in the pig’s life that can contribute to intestinal and immune system dysfunctions that result in reduced pig health, growth, and feed intake, particularly during ...

2016年8月19日 · In recent decades, there has been growing concern regarding stress among pigs because of the undesirable consequences that stress imposes on the normal physiology of pigs, their welfare,...

2008年12月10日 · The present paper is a review of studies on the influence of stressors on reproduction in pigs. The effects of stress on reproduction depend on the critical timing of stress, the genetic predisposition to stress, and the type of stress.

Porcine stress syndrome is a condition in pigs that causes hyperthermia. A genetic disease, it is caused by an intolerance of stress because of a faulty ryanodine receptor. This causes a pig’s cells to rise in calcium and for their metabolism to go through the roof.

2025年2月24日 · Stress in pigs can stem from various factors, with its impact depending on how the animal adapts. It can either lead to negative outcomes or serve as a means of resilience and conditioning. Stress typically progresses through three stages: mobilization (alarm reaction), resistance or adaptation, and exhaustion.
