Calcium in layer feed

Calcium plays a crucial role in layer feed, primarily for the health and productivity of laying hens. Its primary functions include:

1. Eggshell Formation:

Calcium is a key component of eggshells. Laying hens require a high amount of calcium to produce strong, high-quality eggshells. About 94-97% of the eggshell’s composition is calcium carbonate.

2. Bone Health:

Calcium helps maintain the strength of a hen’s skeletal system. During peak laying periods, hens mobilize calcium from their bones to support eggshell production. Adequate calcium in the diet prevents bone thinning (osteoporosis).

3. Muscle Function:

Calcium is essential for muscle contraction, including those involved in egg-laying processes.

4. Nervous System:

Calcium supports proper nerve signaling, which ensures the hens’ overall physiological functioning.

Optimal Levels in Feed:

Laying hens typically require 3.5-4.5% calcium in their feed, depending on their age and production stage.
