Calcium formate-animal feed additive


Animal nutrition plays a key role in livestock health, growth and productivity. As the demand for high-quality animal products continues to grow, so does the search for effective feed additives. One such additive that has received attention in recent years is calcium formate. Derived from formic acid and calcium hydroxide, this compound has unique properties that make it a valuable supplement in animal feed.

Calcium formate properties

chemical composition

Calcium formate, represented by the chemical formula Ca(HCOO)2, is the calcium salt of formic acid. It is produced by reacting formic acid with calcium carbonate or calcium hydroxide. The obtained compound is a white crystalline powder with a molecular weight of approximately 130.1 g/mol.


Calcium formate is highly soluble in water, which facilitates its incorporation into liquid feed. This solubility is a key factor in its effectiveness as a feed additive, ensuring that it can be easily mixed and absorbed in the animal’s digestive system.


The stability of calcium formate is noteworthy, especially compared to other calcium salts. Its high thermal stability makes it suitable for pelleting processes commonly used in animal feed production. This stability facilitates the sustained release of calcium ions in the gastrointestinal tract, optimizing absorption.

Calcium Formate Benefits in Animal Nutrition

Calcium source

Calcium is an essential mineral for animals and plays a vital role in bone formation, muscle function and neurotransmission. Calcium formate is an excellent source of bioavailable calcium. The form in which calcium is present affects its absorption rate, and studies show that calcium formate is absorbed more efficiently than some traditional calcium sources.

pH adjustment

Formic acid is a component of calcium formate, which helps regulate the pH of your digestive system. Maintaining optimal pH is essential for digestive enzyme activity and overall gastrointestinal health. Calcium formate’s ability to regulate pH increases nutrient availability and creates a favorable environment for beneficial gut microbiota.

antibacterial properties

Formic acid is known for its antibacterial properties. When added to animal feed in the form of calcium formate, it can help control the growth of pathogenic bacteria in the digestive system. This antimicrobial effect helps improve intestinal health and reduce the risk of illnesses related to bacterial infections.

Performance and growth promotion

Numerous studies have shown that incorporating calcium formate into animal diets can have a positive impact on growth performance. Improved feed efficiency, increased weight gain, and improved nutrient utilization are observed in poultry, pigs, and other livestock. These performance advantages are attributed to the various physiological effects of calcium formate on digestion and metabolism.

relieve pressure

Livestock often face stressful conditions such as transportation, environmental changes, or disease challenges. Calcium formate has been studied for its potential role in relieving stress-related problems. Research shows it may help reduce the negative effects of stressors on animal health and performance.

Application of calcium formate in animal feed

poultry nutrition

Poultry, including broilers and laying hens, can benefit greatly from the addition of calcium formate to their diets. Improved calcium bioavailability contributes to bone development and eggshell quality in laying hens. Additionally, calcium formate’s pH-adjusting properties help create a healthier intestinal environment for poultry.

pig diet

Pig production systems can also take advantage of the benefits of calcium formate. Studies have shown that adding calcium formate to pig diets can improve growth rate, feed efficiency and bone mineralization. The antimicrobial effect further helps reduce the prevalence of gastrointestinal infections.

Ruminant feed

Although ruminants have unique digestive physiology, calcium formate can still play a role in optimizing nutrient utilization. The controlled release of calcium in the rumen may have a positive impact on microbial activity and fermentation processes. However, the use of calcium formate in ruminant diets requires careful consideration of its interaction with rumen conditions.


In aquaculture, water quality is critical and calcium formate is used to support growth and can enhance growth. alth of aquatic species. Its solubility allows it to be easily incorporated into fish or shrimp feed. Antimicrobial properties may also help maintain a healthy aquatic environment.

Challenges and considerations

While calcium formate has many advantages, there are some considerations when using it as an animal feed additive. These include:


The cost of calcium formate relative to other calcium sources may affect its widespread adoption. Economic viability is a key factor for manufacturers when deciding on feed additives.

optimal inclusion level

Determining the ideal levels of calcium formate in different animal diets requires careful consideration of species, age, and production goals. Levels that are too high can cause imbalances and potentially negative effects.

Interactions with other nutrients

Interactions of calcium formate with other nutrients, especially in complex diets, require thorough evaluation. Understanding how it affects the bioavailability of other minerals is critical to formulating a balanced feed.

regulatory considerations

As with any feed additive, regulatory approval and compliance with safety standards are critical. Producers should be aware of regional regulations regarding the use of calcium formate in animal feed.

in conclusion

Calcium formate is a promising option as an animal feed additive, offering a range of advantages in terms of calcium supplementation, pH adjustment, antimicrobial properties and performance enhancement. Its diverse applications in various livestock species highlight its versatility in modern animal nutrition. However, in order to successfully integrate it into animal diets, cost, optimal inclusion levels and regulatory requirements must be carefully considered. As research in this area continues, calcium formate has the potential to make a significant contribution to the sustainable and efficient production of high-quality animal products.
