Oystershells
OYSTER SHELLS OSTREA No. 1
Oyster shells are a pure natural product and collected by the supplier with his own ships in the North Sea. In the plant right at the port the oyster shells are being washed, dried, heated, crushed and shifted. The finished product is free of sand, stones and dust. The supplier guarantees the absence of salmonellae. Dioxins are tested regularly. The supplier is certified according to ISO 9002.

Oyster shells are a perfect source of calcium for layers. The contained calcium (CaCO3) is dissolved just slowly. Therefore, the resorption in the intestine is about 100%. OSTREA OYSTER SHELLS have a more coarse structure than feed lime. Therefore, the particles stay longer in the muscle stomach (deposit function). Moreover, oyster shells are 5-6 times slower dissolved. As a result the blood calcium level is more constant and higher compared to a Ca-supply via feed lime.

Particel size: 1-2 mm

Ca min. 38 %

recommended for: Poultry feed
Ash 98.0 %
Humidity max. 2.0 %
