Challenges of heat stress on intestinal health in pig husbandry

Global warming has intensified the threat of heat stress in pig husbandry, with the intestine emerging as a primary target of heat-induced injury. This perspective reviews recent advances in our understanding of the complex effects of heat stress on porcine intestinal health. We highlight current intervention strategies implemented in pig farming to enhance resilience against heat stress and mitigate associated intestinal damage. These strategies offer promising avenues to preserve pig health and improve productivity under rising environmental temperatures.
