EFFECT OF FEED ADDITIVES AS AN ALTERNATIVE TO IMPORTED PREMIX ON THE PRODUCTIVE AND PHYSIOLOGICAL PERFORMANCE OF CHICKEN

Abstract

This study explores the impact of using feed additives as an alternative to imported premix on the growth and physiological performance of broiler chickens. Feed additives, which include amino acids, minerals, vitamins, and other elements, are critical for poultry nutrition. The study examines the role of key amino acids such as methionine, lysine, and threonine in improving the growth, immune response, and overall health of broilers. Methionine, in particular, was shown to enhance protein synthesis, reduce fat accumulation, and increase stress tolerance, especially under heat-stress conditions. Similarly, lysine plays a vital role in muscle growth, protein synthesis, and boosting the immune system. The study also highlights threonine’s importance in maintaining gut integrity and promoting nutrient absorption. Another focus of the study is on the limitations and problems associated with the use of traditional protein concentrates and premixes. The high levels of crude protein in such feeds can result in excessive nitrogen excretion, leading to environmental issues such as ammonia buildup and poultry health problems like footpad dermatitis. The research advocates for the use of amino acids as a more sustainable and efficient alternative to protein concentrates, which can reduce nitrogen excretion and improve poultry health. The findings of the study suggest that feed additives, particularly essential amino acids, can serve as a viable alternative to premixes. This approach not only enhances productivity and feed efficiency but also addresses environmental concerns related to nitrogen emissions. The study concludes that the inclusion of methionine, lysine, and threonine in poultry diets improves both productive and physiological outcomes, providing a more efficient and cost-effective alternative to traditional premixes.
