Limestone Feed Grade

Feed grade limestone is used as a calcium source in animal nutrition.

Feed-grade limestone is a high-purity calcium supplement for livestock, essential for bone development, eggshell strength, and metabolic health. It typically contains 36–38% calcium and is available in various particle sizes—from fine powders to granules—to suit different animal requirements. It acts as a crucial, affordable calcium source in feed, preventing deficiencies in cattle, poultry, and pigs. 

Key Characteristics and Benefits 
High Calcium Content: Typically 36% to 38% calcium, providing a vital source of dietary mineral for livestock.
Nutritional Support: Essential for maintaining strong, healthy bones and improving heart function and blood circulation.
Animal Health Benefits: Aids in strengthening eggshells in poultry and prevents metabolic diseases like milk fever in dairy cattle.
Buffering Agent: Functions as a rumen buffer for cattle, helping to manage pH levels during stressful periods.
Particle Sizes: Available in different sizes, including fine powder (e.g., 250 mesh) and granular forms (0.5-1 mm, 2-3 mm). 

Composition and Quality 
Purity: High-purity with 90%–95% calcium carbonate content.
Other Minerals: May contain small amounts of magnesium, silica, or other trace minerals, though high-calcitic limestone is preferred for maximum calcium delivery.
Quality Control: Often ISO-approved, ensuring safety and consistency in animal diets. 

Usage in Livestock 
Poultry: Used for strengthening eggshells.
Dairy Cattle: Used to prevent milk fever and support bone health.
General Livestock: Suitable for pigs, sheep, and horses as a nutritional supplement.
