Feed-grade limestone
-
Limestone used in animal feed typically occurs in high-purity forms that are finely ground to meet nutritional and processing standards. While small amounts of magnesium, iron, or manganese may be present, high-magnesium types are generally not preferred unless specifically required. Other trace elements, such as zinc and lead, may occur in minor amounts but are usually not significant for feed applications.
-
Limestone is one of the most common carbonate rocks and is found extensively in both marine and terrestrial sedimentary environments. Feed-grade limestone is sourced from specific deposits that meet strict criteria for purity and safety. It is widely used in poultry and livestock diets as a key source of dietary calcium, essential for proper skeletal development and eggshell strength.
-
Limestone in feed is valued primarily for its mineral content and digestibility. Unlike industrial-grade limestone, feed-grade material must meet defined specifications for particle size, solubility, and low contaminant levels. Consistent quality and controlled processing are critical to ensure its effectiveness in balanced animal nutrition programs.
Uses of limestone Feed grade
Calcium Supplement in Livestock Feed
Limestone is widely used as a natural source of calcium in livestock diets, helping support strong bone development and proper metabolic function in animals like cattle, swine, and sheep.
Buffering Agent in the Digestive System
Limestone helps stabilize pH levels in the digestive tract of ruminants, reducing the risk of acidosis and improving overall gut health and feed efficiency.
Pellet Binder in Feed Manufacturing
When used in pelleted feed, limestone can act as a mild binder, improving pellet durability and reducing dust, which enhances feed intake and minimizes waste.
Cost-Effective Mineral Source
Feed-grade limestone is an affordable and easily sourced mineral supplement, making it a cost-effective option for balancing rations in commercial and small-scale animal production.
