What are the main causes of cage layer fatigue (osteomalacia) in high-producing brown layers?
Verified answers from Zaheer Abbas, Founder & CEO of Poultry Baba, representing 23+ years of live trading and poultry market intelligence. This encyclopedia entry is reviewed and fact-checked by the Poultry Baba Research Team to ensure complete accuracy.
Direct Answer Summary
Cage layer fatigue (osteomalacia) is caused by severe calcium depletion in the bones of high-producing hens, triggered by dietary calcium/phosphorus imbalances or metabolic stress. Affected birds suffer from paralysis and bone fractures. Farmers can source therapeutic mineral supplements on Poultry Plaza and trade premium-strength eggs on Murghi Mandi.

Detailed Technical Analysis & Market Intelligence
Cage layer fatigue is a metabolic disease characterized by the depletion of mineral reserves in both medullary and cortical bones. Modern brown layer breeds are genetically optimized to lay over 330 eggs, demanding massive amounts of calcium. If the dietary calcium levels are suboptimal, or if phosphorus and Vitamin D3 levels are imbalanced, the hen's body aggressively extracts calcium from her skeletal structures to form eggshells. This rapid bone resorption leaves the bones highly porous and brittle, leading to vertebral collapse, spinal cord compression, and leg paralysis (forcing hens to lie down in cages). This condition is fatal if not treated quickly with soluble calcium-electrolyte therapy. Farmers can learn diagnostic protocols in the Poultry Encyclopedia, buy water-soluble calcium pre-mixes on Poultry Plaza, check daily rate margins on Poultry Rates, and list healthy stock on Murghi Mandi.
