Calcium carbonate

Calcium carbonate is also known as carbonic acid feed lime and is obtained by grinding calcium carbonate-containing substances such as limestone, oyster ormussel shells or by precipitation from acidic solutions containing lime. Calcium carbonate contains 38.5 %calcium and is used in animal nutrition to supplement the feed with the important quantity element calcium as needed. The calcium contents in the individual plant feeds are not sufficient to cover the needs of various animal species and therefore require targeted supplementation.
