Thank you @ all, for the interesting contributions.

The ideal protein ratio expresses dietary essential amino acids in a relationship to each other, using lysine as the standard. The balance of amino acids is critical to avoid deficiencies and excess of amino acids in the diet. Because there is no storage of amino acids in the body, excess amino acids are deaminated and that excess nitrogen is sent to the uric acid cycle in birds to produce uric acid, which requires energy for its biosynthesis and water for excretion. Not having the proper balance of amino acids in the diet will likely result in poorer growth performance, wetter excreta, wetter litter, and higher ammonia production in the house. The balance of amino acids for poultry changes with age so it is important to use the proper balance for each growing and productive phase.

Take you so much for this wonderful information

Increasing the total protein level while maintaining ideal amino acid ratios can increase feed utilization efficiency.

Increasing protein content in the diet will increase feed cost and can negatively impact intestinal health and productive performance. Excess dietary protein or feeding protein of low digestibility will likely increase protein fermentation in the hindgut causing detrimental effects on intestinal health. Further, excess protein can lead to wet excreta and wet litter, which is going to increase ammonia in the house and negatively affect productive performance of birds. Diets for poultry should be supplemented with amino acids, mainly methionine, lysine, and threonine, to reduce diet cost, improve the profile and balance of amino acids, reduce crude protein in the diet, and to improve the performance of birds.

Amino acids like methionine and cysteine help birds cope with environmental stressors
-
Improves the surface area for nutrient absorption, leading to better feed efficiency and growth in broilers and layers.
-
Adequate amino acid intake promotes healthy villus height and crypt depth in the intestines, which enhances nutrient absorption.
-
Amino acids being the end product of the breaking down of protein, improves laying performance, and builds block for weight gain in body and meat, in broilers.
