The role of amino acids deficiency in broiler chick’s infection, with Newcastle disease: A review

Abstract

The chosen birds growing fast are kept in cages with high stocking densities in intensive poultry production systems. According to estimates, genetic selection accounts for 85-90% of performance gains, with management and nutrition improvements accounting for the remaining 10 to 15%. Newcastle disease, which has a prevalence rate of 28.9%, is the most common viral infections in poultry, affecting both domestic and wild bird types. Immune modulation, vaccination, and a healthy diet are the major strategies that may be utilized to build immunity in hens in order to stop and manage the development of illness. Chickens immune systems directly affect their health, and help them grow into healthier birds. Most essential amino acids are thought to be vital components for cytokine synthesis and immunological function
