Newly weaned piglets are highly vulnerable to cold stress. Optimal nursery temperature management is one of the most impactful welfare interventions in pig production.
Temperature management in nursery pens is one of the most cost-effective welfare improvements available in pig production. Cold piglets are uncomfortable, eat less, are more vulnerable to disease, and divert energy from growth to thermoregulation. Providing appropriate ambient temperature, draught-free lying areas, and supplementary heat sources such as heat lamps creates the thermal comfort zone that allows piglets to feed, explore, and grow without cold stress. Monitoring piglet behaviour by whether they scatter or huddle provides a practical real-time welfare indicator.
