Calcium Particle Size for Breeders at Different Stages

👋 Hey, Chicken Farmers! Keeping your hens healthy and productive starts with the right nutrition—especially calcium! Let’s break down why particle size matters and how it affects eggshell formation.

🐔🌞 Calcium Particle Size:

The feed particle diameter should increase with the age of the breeder and be accompanied by an increased source of coarse calcium to maintain the development of the breeder's stomach.

🐚Limestone(0~2mm): Limestone provides a source of calcium. When hens eat limestone, it easily dissolves in the acidic environment of the gizzards. Small particles of limestone will dissolve quickly and provide calcium, but since eggshells are formed during the dark hours of the night, ground limestone does not provide enough calcium to aid in the formation of the eggshell.

🦪Oyster Shells(2~4mm): Oyster shells provide a source of calcium. Their large particles remain in the gizzard longer and gradually release calcium throughout the night into the digestive tract and then through the blood to the uterus.

🌞 Why It Matters::

🐔 Egg-laying hens can maintain a high egg production for a long time and need to supplement calcium during the eggshell formation period.

🐔 Proper nutrition and management in the new hen stage can prevent eggshell quality degradation during the production cycle.
