Intensive housing: the last straw for pigs?

Area of Science:

• Animal Science
• Ethology
• Environmental Biology

Background:

• Livestock environments significantly influence animal productivity and welfare.
• Pigs (Sus scrofa domesticus) are ecologically generalist species with broad adaptability.
• However, pigs exhibit specific limitations in space requirements and tolerance to pen materials.

Purpose of the Study:

• To explore the concept of coping in pigs as a link between environmental conditions and their responses.
• To identify the optimal environmental conditions for pig performance.
• To evaluate the biological costs associated with coping and the ethical justification of current housing practices.

Main Methods:

• Literature review and synthesis of existing research on pig behavior, physiology, and environmental interactions.
• Analysis of environmental factors such as temperature requirements and feeding facilities.
• Conceptual framework development based on the "coping" concept.

Main Results:

• Pigs demonstrate adaptability but have defined limits to their environmental tolerance.
• Specific environmental parameters, like temperature and feeding systems, influence pig performance.
• The process of coping can incur a biological cost, even in adapted environments.

Conclusions:

• The "coping" concept provides a framework for understanding livestock-environment interactions.
• While pigs can adapt, their limits necessitate careful consideration of housing conditions.
• Ethical questions arise regarding the justification of keeping pigs in environments, even those to which they have adapted.
