Abstract

The article focuses on the impacts of heat stress (HS) on cattle production, highlighting its effects beyond reduced nutrient intake. Heat stress compromises the intestinal barrier, causing gastrointestinal hyperpermeability that allows antigens to enter circulation and activate the immune system. This immune activation alters nutrient partitioning, increasing insulin secretion and changing fuel utilization in tissues, which contributes to decreased productivity in livestock. Severe heat stress can lead to inflammation-induced complications such as hypercoagulation and endothelial dysfunction, potentially resulting in lethal outcomes. The study emphasizes the complex physiological responses to HS that affect postnatal growth and productivity in farm animals.
