Limestone (Feed Grade) is an excellent source of calcium for animal feeds. Animals like chickens, cows, and pigs require calcium for proper bone development, eggshell formation, and overall health. Including limestone in their diet helps ensure they receive an adequate supply of calcium.

What is Limestone?
Limestone is a sedimentary rock primarily composed of calcium carbonate (CaCO3). Limestone has numerous applications, one of which is as a feed-grade material. In the context of livestock and poultry farming, limestone is often used as a calcium supplement in animal feed.
Limestone powder for livestock
Limestone powder is commonly used as a calcium supplement in livestock feed. It provides essential calcium to animals, which is crucial for proper bone development, eggshell formation (in poultry), muscle function, nerve transmission, and overall health.
Here are some key points about using limestone powder for livestock feed:
- Calcium Source: Limestone powder is a natural and cost-effective source of calcium. Calcium is an essential mineral for animals, and it must be included in their diet to maintain their health.
- Ground Limestone: Limestone used for livestock feed is usually ground into a fine powder. Grinding increases the surface area of the limestone, making it more easily digestible and absorbable by animals.
- Particle Size: The particle size of limestone powder can impact its effectiveness in animal diets. It’s essential to have a consistent particle size to ensure uniform mixing in feed formulations.
- Calcium Content: The calcium content of limestone can vary depending on the source and quality. The calcium content is usually expressed as a percentage of calcium carbonate (CaCO3).
- Phosphorus Balance: While calcium is important, it’s also essential to maintain a proper balance between calcium and phosphorus in the diet. The calcium-to-phosphorus ratio is crucial for optimal growth and health.
- Feed Formulation: Animal nutritionists and manufacturers carefully formulate diets to ensure animals receive the right amount of nutrients, including calcium. Limestone powder is included in these formulations to meet the animals’ calcium requirements.
- Regulatory Standards: In many countries, there are regulatory standards and guidelines for the use of limestone and other additives in animal feed. These standards ensure the safety and quality of feed products.
- Benefits: Providing adequate calcium through limestone supplementation helps prevent deficiencies that can lead to health problems like weak bones, leg disorders, eggshell quality issues (in poultry), and more.
- Health and Productivity: Proper nutrition contributes to the overall health and productivity of livestock. Animals that receive balanced diets are more likely to grow well, produce quality products (such as meat and eggs), and have fewer health issues.
It’s important to consult with a qualified animal nutritionist or veterinarian when formulating diets for livestock. They can help ensure that the diets meet the animals’ nutritional needs and provide guidance on using limestone powder or other supplements effectively.
Limestone for poultry feed
Limestone is commonly used as a calcium supplement in poultry feed. Providing an adequate amount of calcium is essential for the health and productivity of poultry, particularly laying hens. Here’s how limestone is used for poultry feed and its benefits:
Benefits of Limestone in Poultry Feed:
Eggshell Formation
Calcium is a critical component of eggshells. Laying hens require a sufficient supply of calcium to produce strong and properly formed eggshells. A deficiency in calcium can lead to thin, weak, or irregularly shaped eggshells, making them more prone to cracking or breaking.
Bone Health
Calcium is vital for bone development and maintenance in poultry. It helps support skeletal structure and overall bone health. Adequate calcium intake can help prevent skeletal deformities and leg disorders in birds.
Limestone for broiler feed
Limestone is used in broiler feed to supply calcium, necessary for bone development, eggshell formation, and muscle function. Ground into a powder, it’s included in the feed to prevent calcium shortages in broiler chickens.
Limestone for dairy cows
Limestone is added to dairy cow feed to provide calcium, vital for milk production, bone strength, and overall health. Ground into a powder, it’s mixed into feed to prevent calcium deficiencies in dairy cows.
Limestone for sheep feed
Limestone is used in sheep feed as a source of calcium, essential for bone health, muscle function, and overall well-being. It’s typically ground into a fine powder, mixed into feed formulations, and helps prevent calcium deficiencies in sheep.
