Calcium formate is an organic calcium salt that has been widely used in laying hen feed as an efficient calcium supplement in recent years. It not only provides a calcium source with high bioavailability, but also has the characteristics of an acidifier, playing a comprehensive role in the nutritional management of laying hens.
Main functions and advantages
Calcium formate can significantly increase the egg production and hatching rate of laying hens, while enhancing the hardness of eggshells and reducing the proportion of cracked and soft-shelled eggs, thereby improving egg quality and breeding benefits.
High-efficiency calcium supplementation, meeting peak demand
Laying hens need about 3 to 3.5 grams of calcium per day during the laying period. Calcium formate has a calcium content of over 30% (up to 31% in some products), and has a high absorption and utilization rate, making it particularly suitable for calcium supplementation from the early stage to the peak period of laying. The retention rate of calcium in hens is only about 50%, so calcium formate with a high absorption rate can effectively avoid waste.
Regulate the gastrointestinal environment and inhibit harmful bacteria
calcium formate can slowly release free formic acid after entering the digestive tract, lower the pH value in the stomach, promote the activity of pepsin, and improve the digestibility of protein; At the same time, it creates an acidic environment to inhibit the growth of harmful microorganisms such as Salmonella and reduce the occurrence of intestinal diseases.
It has antioxidant and anti-mold effects, can lower the pH value and acid binding capacity of feed, reduce mycotoxin contamination, and extend the storage time of feed. Compared with acidifiers such as citric acid, calcium formate is less prone to deliquescence and does not corrode equipment, making it more suitable for industrial production.
Adding calcium formate helps maintain an appropriate calcium-phosphorus ratio (4:1 to 6:1) in the diet and prevent the thinning of eggshells caused by calcium-phosphorus imbalance. At the same time, amino acids form soluble salts with calcium, further promoting calcium absorption.
suggested usage
Start time: It is recommended to start adding calcium two weeks before the onset of pregnancy (approximately 18 weeks of age) to ensure a smooth transition in calcium intake.
Addition form: It can be directly mixed into the complete feed or combined with large-grained calcium carbonate for free consumption in the afternoon to meet the eggshell sedimentation needs at night.
Nutritional combination: When used in combination with vitamin D₃ (1500 IU/kg feed is recommended), it can significantly enhance calcium absorption efficiency.
✅ conclusion
Calcium formate is a high-quality feed additive that integrates efficient calcium supplementation, acidification, antibacterial and absorption-promoting functions. It is suitable for the entire egg-laying cycle of laying hens, especially in the early and later stages of egg-laying, where it is particularly effective in maintaining high yields and improving eggshell quality. Reasonable use can not only enhance production performance but also reduce feed loss and disease risks, bringing considerable economic benefits.
