Cattle suffering from heat stress have decreased feed intake, hypoglycaemia, decreased fat mobilisation (even with hypoglycaemia), and increased BUN. Peripheral vasodilation also contributes to a loss of GIT integrity which is thought to stimulate an inflammatory cascade driven by lipopolysaccharide and reinforced by leptin which severely exacerbates the chronic metabolic effects. Our developing understanding of the physiological pathways of heat stress allows us to make nutritional interventions to reduce its clinical severity and production effects
