ARTICLE 78 FEED & ADDITIVE MAGAZINE June 2025 SHIELDING POULTRY PERFORMANCE FROM THE HEAT Dr. Stephanie Ladirat R&D Director NUQO Feed Additives “One of the primary mechanisms through which heat stress negatively impacts poultry is the activation of the body's inflammatory response. Inflammation in the gut can lead to impaired nutrient absorption and digestive capacity, reducing feed efficiency and weight gain. Additionally, heat stress causes physiological changes such as increased respiration rates, altered blood circulation, and hormone imbalances, which further inhibit optimal production.” Heat stress is a significant challenge for the poultry industry, with considerable economic consequences. As temperatures rise, poultry experience physiological changes that can compromise their health and productivity. Heat stress leads to increased inflammation and metabolic disorders, which adversely affect the digestive system and reduce feed intake, ultimately diminishing growth and performance. One of the primary mechanisms through which heat stress negatively impacts poultry is the activation of the body's inflammatory response. Inflammation in the gut can lead to impaired nutrient absorption and digestive capacity, reducing feed efficiency and weight gain. Additionally, heat stress causes physiological changes such as increased respiration rates, altered blood circulation, and hormone imbalances, which further inhibit optimal production. The result is a loss of profitability for poultry farmers due to reduced growth rates, lower feed conversion ratios (FCR), and, in extreme cases, increased mortality rates. AN ADVANCED YET SIMPLE SOLUTION FOR HEAT STRESS PREVENTION Nuqo RED is a cutting-edge feed additive designed to mitigate the detrimental effects of heat stress on poultry. This new hybrid technology is based on micro-encapsulation of capsaicin, the active molecule in chili peppers, known for its potent anti-inflammatory properties. Capsaicin is an effective molecule that helps regulate inflammation, but its high irritancy has traditionally made it difficult to use in feed formulations. To overcome this challenge, Nuqo developed a unique encapsulation technology that ensures the safe use of capsaicin. Nuqo RED encapsulates the capsaicinoids in a fat-based coating, preserving their activity while minimizing the risk of irritation for operators and animals. In addition, this technology ensures that capsaicin reaches the small intestine in its active form to act on specific gut receptors, the TRPV1 receptors. The result is a highly efficient and user-friendly product that reduces inflammation, enhances thermoregulation, and improves overall performance during heat stress.
