Abstract: Modern swine production faces increasing challenges with heat stress, traditionally mitigated by reactive environmental controllers that lag behind the rapid physiological response of the animals. This systematic review evaluates the feasibility of using the pig as a biosensor to support predictive environmental control in finishing production. Following the PRISMA protocol guidelines, 48 scientific articles were selected and analyzed. The results indicate that collective behaviors, such as occupation rate and postural changes, combined with peripheral hemodynamic responses monitored non-invasively by computer vision and infrared thermography, precede critical internal enthalpy fluctuations. Predictive algorithms utilizing these biological data have demonstrated efficacy in anticipating and smoothing the heat stress curve. We conclude that system-animal integration is a promising approach to optimize performance; however, scalability to commercial farms requires the advancement of rugged hardware focused on local processing (Edge Computing).
