Egg Shell Quality

Pacific Pearl Oyster Shell Calcium

The use of Pacific Pearl Brand Oyster Shell has been shown to contribute to an overall egg shell quality program and can pay for itself by reducing undergrades, egg loss, and extending the the length of the lay cycle - all of which puts money in the producer's pocket!

Pacific Pearl Oyster Shell is a more digestible type of shell; it is sized specifically for solubility, availability, and retention time in the gizzard. In contrast, the shell from the southeast (Pilot) more closely resembles limestone in shape and hardness, i.e., it is denser and therefore, available for a shorter time in the bird, with considerable passthrough of unused calcium.

A quick examination of both types of shell and a weighing out of equal amounts will immediately show the important difference in surface area, with the Pacific Pearl Oyster Shell having twice the surface area. More surface equals more solubility and more availability.

When it comes to attaining good egg shell quality, a preventative maintenance policy rather than a "fix it when it breaks" approach works best. The extra production of precessible eggs is more likely to be accomplished when 3-5% oyster shell is added from the first day of production, rather than only starting the 50% limestone replacement midway through the lay cycle.

We are currently supplying over 30 million layers in California, Oregon, Washington, British Columbia, and Alberta. We have been supplying the highest quality calcium to the poultry and dairy industry since 1924.
