The poultry industry, a vital constituent of global food production, poses formidable threats from immunosuppressive illnesses that compromise poultry health, output, and economic sustainability. Due to various infectious and non-infectious agents, these immunosuppressive provisions significantly heighten birds' susceptibility to secondary infections and undermine the efficacy of vaccination. Poultry mortality and morbidity can be caused by non-infectious factors such as environmental stressors and nutritional deficiencies. The overuse of antibiotics in poultry production raises concerns about antibiotic resistance and public health, leading to the search for natural alternatives. Turmeric, scientifically known as Curcuma longa, has emerged as a promising solution due to its various attributes, including antimicrobial, antioxidant, anti-inflammatory, and immunomodulatory properties. It is poised to effectively supplant synthetic antibiotics in poultry, thus mitigating the risks to public health. This review paper investigates the role of turmeric as a natural antibiotic against immunosuppressive diseases in poultry. It comprehensively explores the multifaceted causes of immunosuppression in poultry, encompassing environmental stress, nutritional factors, and infectious agents. Furthermore, the article explores how turmeric can combat various issues and highlights its potent antimicrobial, anti-inflammatory, and antioxidant properties. Turmeric has been shown to enhance growth, boost immune function, and mitigate the adverse effects of stress, making it a valuable and sustainable solution for the poultry industry. By alleviating the risk of immunosuppression, turmeric safeguards avian health and augments the industry's overall success. This paper underscores the significance of embracing natural remedies like turmeric to uphold poultry health and well-being while diminishing reliance on synthetic antibiotics.
