Optimise cooling for high productive sows through advanced modelling techniques

PhD defence, Tuesday 18 October 2022. Tao Huang.

Tao Huang

During his PhD study, Tao Huang established a mechanistic thermophysiological model for simulating the thermoregulation processes of pigs. The vasodilatation and panting effects, which were not explicitly considered in past models, were comprehensively interpreted. Based on the mechanistic model, he developed effective temperature for sows to reasonably reflect the actual thermal status of sows as influenced by the dynamic ambient environment. Further, he identified the characteristics of conductive heat transfer between sows and the contact floor surface and proposed feasible approaches for efficiently modelling the performance of individualised ventilation in constrained sow houses. The new research findings strongly contribute to a better understanding of the thermoregulation processes of sows in hot climates and promote the optimal implementations of cooling strategies for mitigating heat stress.

The PhD study was completed at the Department of Civil and Architectural Engineering, Faculty of Technical Sciences, Aarhus University.
