Calcium carbonate is an inorganic compound with the chemical formula CaCO3. It is the main component of limestone, marble, etc. Calcium carbonate is usually white crystals, odorless, basically insoluble in water, and easily reacts with acids to release carbon dioxide. It is one of the common substances on the earth. It is found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.
Calcium carbonate is a common mineral that is mainly used as a calcium source in feed to supplement the calcium needed for animal bones and teeth.
In addition, calcium carbonate also helps to promote the digestion and absorption of animals, improve the nutritional value of feed, make the feed more uniform and taste better, thereby increasing the animal's appetite and ensuring the health of the animal.
For poultry such as laying hens, adding an appropriate amount of calcium carbonate to the feed can improve the quality of eggshells and reduce the egg breaking rate. It is worth noting that different types of calcium carbonate have different particle sizes, and the amount of feed added also varies depending on the type. Generally speaking, the particle size of heavy calcium carbonate is larger, and the added amount is 0.5~1%, while the particle size of light calcium carbonate is smaller, and the added amount is generally 1.5~3%. When choosing calcium carbonate, comprehensive consideration should be given to factors such as animal species, growth stage, feed type, etc.
