Abstract
Heat stress can seriously impair broiler chicken development and meat quality, so scientists are looking for sustainable additives like microalgae that might mitigate these impacts. Poultry health and productivity are seriously impacted by heat stress, which is a major concern. Incorporating compounds rich in antioxidants into the feed of chickens is crucial for addressing the problem of heat stress and maintaining the appropriate operation of the redox system. Animal and human health both benefit from the high antioxidant content of microalgae. Many researches have demonstrated that, when handled properly, microalgae can enhance immunity, nutrition, stress relief, aquatic bioremediation, disease resistance, and inhibit bacterial quorum sensing. Microalgae’s anti-cancer, anti-inflammatory, antibacterial, and antioxidant qualities contribute significantly to its ability to reduce the bad effects of heat stress. As a result, we can advise using microalgae instead of protein sources in chicken feed to lessen the harmful effects of heat stress because it has excellent properties and is reasonably priced to maximize profit.
