Calcium Carbonate Limestone Feed Grade
CAS Number: 471-34-1
Calcium Carbonate (Limestone) Feed Grade is the most economical calcium source for animal nutrition, widely used in poultry feeds to support eggshell formation, bone mineralisation, and blood calcium homeostasis. It is available in ground limestone and oyster shell forms with varying particle sizes to meet the different calcium release profiles required by layers versus broilers. Our product provides high calcium content with low heavy metal contaminants.
