Graymont Limestone Ground 25KG

Cal Carb Supercal – Glass Rock is a medium grind carbonate with a particle size larger than Cal Carb 0 or Cal Carb 325 grind, but less than Cal Carb Poultry Grit.

High-quality calcium carbonate product primarily used in animal feed and agricultural soil amendment, but it is generally a high-quality, finely ground limestone (CaCO3) product.

Animal Feed Supplement (Poultry and Livestock)

• Primary Use: The name "Supercal" is a brand often used for feed-grade limestone in North America, particularly for poultry.

• Purpose: It is an essential, highly available source of calcium for livestock and poultry.

common and essential mineral supplement in cattle diets, particularly in the form of fine-ground calcium carbonate.

Here is a breakdown of why and how it's used for both dairy and beef cattle:

1. Essential Calcium Supplementation

• Calcium Source: High-calcium ground limestone (like Supercal) is an excellent and cost-effective source of calcium.

• Physiological Needs: Cattle require significant amounts of calcium for:

  • Bone Health: Formation and maintenance of strong bones and teeth.

  • Muscle Function: Including nerve impulse transmission and muscle contraction.

  • Lactation (Dairy Cows): Dairy cows have an extremely high demand for calcium to produce milk, making supplementation crucial to prevent deficiencies like milk fever (hypocalcemia).

  • Growth: Essential for proper development in growing calves and heifers.

2. Digestive Buffer (Rumen Health)

• pH Regulation: Limestone acts as a buffer (antacid) in the cow's digestive system, particularly in the rumen.

• High-Concentrate Diets: It is often added to rations that are high in grain or concentrates, which can cause the rumen $\text{pH}$ to drop too low, leading to acidosis. Ground limestone helps neutralize this excess acid, which maintains a healthy environment for the rumen microbes to properly digest feed.
