How to optimize Calcium, Phosphorus, and Amino Acids for peak eggshell quality and sustained laying performance.
The Biological Factory
A modern laying hen is a high-performance biological factory, capable of producing over 320 eggs per year. This intensive production demands a highly specialized nutritional profile, completely different from broilers.
The Calcium-Phosphorus Dynamic
Eggshells are primarily composed of calcium carbonate. A laying hen requires massive amounts of dietary Calcium (typically 3.5% to 4.5% of the diet). However, Calcium absorption is heavily dependent on Available Phosphorus and Vitamin D3.
Formulators must provide coarse limestone in the diet so the hen has a slow-release source of calcium in her digestive tract during the night when the eggshell is being formed.
Energy and Amino Acids
While calcium forms the shell, protein forms the egg white and yolk. Methionine is usually the first limiting amino acid in layer diets. Precise formulation based on digestible amino acids ensures optimum egg size and prevents fatty liver hemorrhagic syndrome, which occurs when hens consume excess energy due to unbalanced amino acids.
