The most important amino acid in poultry nutrition is…
Posted by Jeffery Escobar on December 4, 2024 at 4:50 pmWhat is the most important amino acid in poultry nutrition and why? Think about how each amino acid is digested, absorbed, and metabolize in the body of a chicken before providing an answer or comment.

At the biochemical level of protein synthesis, which is essential for growth and other functions, all amino acids are equally important because an uncharged tRNA will cause protein synthesis to stop resulting in no protein, waste of energy, and limited growth. At the dietary nutritional level, we can talk about dietary essential (EAA) and non-essential amino acids (NEAA). EAA are those that the animal cannot make in the body from readily available sources at a rate sufficient to sustain appropriate growth and therefore should be supplemented in the diet. We normally consider arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine as EAA whereas alanine, asparagine, cysteine, glutamine, glycine, proline, serine, selenocysteine, and tyrosine as NEAA. For practical supplementation in poultry diets we normally consider lysine, methionine, threonine and depending on ingredients and crude protein level isoleucine and valine.
