Globally, the poultry sector plays a significant role in addressing food security and sustainability by providing a useful source of protein for billions of people. In modern chicken farming, proper nutrition is critical to maintaining optimum health, growth, and output. Proper feeding regimens that provide the birds with the nutrients they require based on their type, age, and stage of development are critical to improving efficiency and sustainability. The review concluded that using organic acids and exogenous enzymes as feed additives improves nutrient utilization and efficiency. Organic acids, such as formic and propionic acids, are useful in inhibiting pathogenic bacteria such as Salmonella and Escherichia coli in the stomach by maintaining an acidic environment. This acidic environment also promotes the existence of older, healthier gut bacteria, which aids in the absorption and digestion of food. As a result, the birds' gut condition improves, and they have fewer intestinal ailments, resulting in higher performance. Exogenous enzymes exist in non-starch polysaccharides (NSP) such as phytate, xylan, and βmannan. They improve nutrient energy intake in animal bodies by changing the structures of non-carbohydrate parts of the feed. Furthermore, phytase reduces the need for inorganic phosphorus supplementation in feeds by hydrolyzing phytates that bind phosphorus. Furthermore, xylanase and mannase enzymes improve energy assimilation, reducing food waste as these two plant cell wall-wasting components are digested. Moreover, the use of these feed additives in chicken production contributes to the aims of sustainable agriculture by improving resource utilization and reducing the environmental effect of poultry farming. Innovation in feed techniques, such as using organic acids and exogenous enzymes, will help the global poultry business survive.
