Calcium

[Manimaran Jeyaseelan]

For peak-laying hens, the ideal calcium percentage in feed is generally between 3.5% and 4.5%. The particle size of calcium sources is important because it directly impacts calcium absorption and utilization in the hen’s digestive system.

Why particle size matters:

Absorption:

Smaller particles dissolve faster, leading to better calcium absorption.

Digestion Time:

Larger particles have a longer residence time in the digestive tract, which can impact the timing of calcium availability for eggshell formation.

Eggshell Quality:

Coarse particles, like large limestone or oyster shell, can contribute to improved eggshell strength and thickness.

Calcium Utilization:

By optimizing the particle size, hens can efficiently use the calcium they consume for eggshell formation, rather than drawing from their bone reserves.

In summary, the particle size of calcium sources influences:

Calcium availability for eggshell formation .

Eggshell quality (thickness, strength) .

Overall calcium utilization by the hen

For peak-laying hens, the ideal calcium (Ca) percentage in the feed is about 3.5% to 4.5%, depending on the breed and egg production level. Most commercial layer feeds are formulated around 4% calcium during peak production.

Hens need a lot of calcium mainly for eggshell formation – an eggshell is about 95% calcium carbonate. If calcium is too low, there will be problems like: Thin or soft shells, Shell-less eggs, Lower egg production, Weaker bones (because hens start pulling calcium from their bones if the feed doesn’t supply enough).

1. Fine (small) particles are digested quickly in the gut. They give a fast calcium boost right after eating, which is good for general body needs.

2. Coarse (larger) particles like coarse limestone or oyster shell, stay longer in the gizzard and dissolve slowly.

This slow release of calcium is crucial <em data-start=”1028″ data-end=”1046″ style=”font-size: inherit;”>during the night, when the hen is actually forming the eggshell (hens don’t eat at night, but they still need calcium to make the shell).

Using a mix of fifine and coarse calcium sources ensures that the hen has immediate and long-term calcium available, improving shell quality and overall health.

The ideal calcium percentage in feed for peak-laying hens is typically around 3.5%. The particle size of calcium sources is important because it affects how readily the hens can absorb and utilize the calcium for eggshell formation.

[Amir Sohel]

The ideal calcium percentage in feed for peak-laying hens is typically around 3 to 4%. The particle size of calcium sources is important because hens prefer granular calcium, and particle size can affect calcium solubility and utilization.

[Bello Bashir Bello]

For peak-laying hens, the ideal calcium percentage in feed is generally between 3% and 4%. Particle size of calcium sources, like limestone or oyster shell, is important because it affects calcium bioavailability and retention, influencing eggshell quality.
