Egg-cellent shell quality: Learn the basics

In the webinar “Egg-cellent shell quality: Learn the basics,” Price explained the essentials for a premium egg and the many different factors affecting eggshell quality. According to Price, producers must start thinking about egg development and quality as soon as the birds are in the pullet barn, where the skeleton, immune and digestive systems are developed. Proper development of these key systems creates a consistent growth pattern, maximising the production from the layer.

Calcium: 94% of the eggshell

Price discussed the importance of calcium for a hen that is expected to lay almost an egg a day. Different feeding programmes will have different calcium particle sizes, which directly affect how well calcium is absorbed.

To get good performance out of the bird, we have to make sure we are maintaining the health of the gut to allow for proper calcium absorption. To do this, producers must supplement enough calcium in the feed for the bird to maintain her own health and produce an egg a day.

What about the minerals?

Price discussed how minerals contribute to the different stages of egg synthesis. Selenium protects the cells and integrity of the reproductive tract. Copper is important for eggshell development, pigments and collagen formation. Manganese aids the formation of the bone and organic matrix of eggshells and is a co-factor in glycoprotein enzyme for shell formation. And, finally, zinc helps bone and eggshell calcification, keratin shell membrane formation and eggshell carbonate production.
