HEAT STRESS IN SWINE AND NUTRITION Maintain the physiological and oxidative balance of your swine with animal nutrition
Animals are constantly exposed to stressful events during the rearing cycle: temperature fluctuations, dietary changes, vaccinations, treatments, and many other stressors that affect well-being and production. The effect of heat stress in swine is a series of complex interrelated responses that often result in a general decrease in the animal’s immune defenses, as the activation of the hypothalamic-pituitary-adrenal axis increases cortisol production, which has an immunosuppressive role. Adding to the overall stress impact is the increased production of ROS (Reactive Oxygen Species), also known as free radicals. The animal’s body has systems to prevent these cellular metabolism byproducts from causing oxidative damage; however, under stress conditions, the high ROS production saturates these antioxidant systems, leading to cell death.
Preserving animal health is a priority in the swine sector, and a possible intervention against heat stress in swine is to modulate its effects when unavoidable. Several studies show that extracts from certain plants help reduce the effects of heat stress in swine due to their components. For example, salicylic acid found in some plants can modulate the inflammatory process after acetylation, and lignins, once hydrolyzed, can modulate antioxidant processes.
NORMOTERM is a plant-based product supporting physiological and oxidative balance in the organism. It is available in both powder and liquid forms. The powder version is enriched with vitamin C, while the liquid version contains vitamin PP. Both vitamins enhance the antioxidant activity of the natural components in the products and participate in various metabolic processes.
NORMOTERM ORAC is similar to the previous product but with plant-derived polyphenols to enhance its antioxidant effect. Several studies recognize the powerful antioxidant action of polyphenols, and some authors report a greater efficiency of these molecules compared to common antioxidants used in animal nutrition, such as vitamins C and E.
