Limestone powder is a key ingredient in animal feed because it is a rich source of calcium, which is essential for the healthy growth and development of livestock and domestic animals. It can be used in the diets of many animals.

Cattle: Limestone powder supports bone and teeth formation, muscle excitability, blood clotting, and cardiac regulation. Young cattle generally require more limestone powder than older animals.

Poultry: Limestone powder helps with eggshell development and strengthens the skeletal structure of chickens. For broiler feed, 1–1.5% limestone powder is typically added, while laying hen feed may contain 2–3%. Excessive limestone powder can result in white feces and reduced appetite.

Other animals: Limestone powder can also be included in the diets of pigs, horses, and sheep. It aids in proper bone and teeth development, muscle contraction, nerve impulse transmission, digestion, and eggshell strengthening.
