feed additive | calcium formate, as a new feed additive, is suitable for weaned piglets. the nutritional effect of calcium formate is mainly realized by its formic acid decomposable in gastric acid environment. it mainly improves the growth performance of weaned piglets in the following ways: 1, reduces the PH of gastrointestinal tract, and is beneficial to activate pepsinogen, make up for the deficiency of digestive enzymes and hydrochloric acid secretion in the stomach of piglets, and improve the digestibility of feed nutrients. 2, maintain a low PH value in the gastrointestinal tract, thereby preventing the growth and reproduction of Escherichia coli and other pathogenic bacteria, and promote the growth of some beneficial bacteria (such as Lactobacillus)! It produces volatile fatty acids in the cecum and node and acts as an antibiotic! In addition, beneficial bacteria such as lactobacillus can cover the intestinal mucosa! To protect it from toxins produced by Escherichia coli! So as to prevent diarrhea related to bacterial infection. 3, can play the role of chelating agent in the digestion process! It can promote the absorption of minerals in the intestine, improve the energy utilization of natural metabolites, increase the feed conversion rate, prevent diarrhea and diarrhea, and improve the survival rate and daily weight gain of piglets. At the same time, calcium formate also has anti-mold and fresh-keeping effects. experiments have proved that adding 0.8 ~ 1.5% calcium formate to the feed can cover the intestinal mucosa from the invasion of toxins, and control and prevent the occurrence of diarrhea and diarrhea related to bacteria. German research found that calcium formate can improve the feed conversion rate by 7-8% when 1.3% is added to the diet of piglets, and the occurrence of diarrhea can be reduced by adding 0.9%. Adding 1.5% can improve the growth rate of piglets by 1.2%, and the feed conversion rate is 4%. Adding 1.5% and 175]/㎏ copper can increase the growth rate 21% and the feed conversion rate 10%. Domestic studies have shown that adding 1 ~ 1.5% calcium formate to the first 8 Sunday diets of piglets can prevent diarrhea and diarrhea, increase the survival rate, increase the feed standard rate by 7 ~ 10%, and reduce feed consumption by 3.8%. The daily gain of pigs is 9 ~ 13%; adding calcium formate to silage can increase the content of lactic acid, reduce the content of butyric acid, and increase the nutritional content of silage. |
application of industrial grade calcium formate | calcium formate, as a new type of early strength agent, has dual functions, which can not only speed up the hardening speed of cement and improve the early strength, but also avoid too slow setting speed under winter construction or low temperature and humidity, so that cement products can be put into use as soon as possible to increase the strength, especially to contribute greatly to the early strength. For a long time, calcium chloride has been used in engineering, but calcium chloride has the effect of corroding steel bars. Chlorine-free coagulants have been developed at home and abroad. Calcium formate is a new type of early strength material that can effectively accelerate the tricalcium silicate in cement. The hydration of C3S increases the early strength of cement mortar, but it will not cause corrosion to steel bars or pollution to the environment. Therefore, it is also widely used in oilfield drilling and cementing. Product characteristics speed up the hardening speed of cement and shorten the construction period. Shorten the setting time and form early. Improve the early strength of mortar at low temperature. Anti-freezing and rust resistance. Technical performance and characteristics Calcium formate is white or off-white crystalline powder. Under standard curing conditions, this product can make concrete final setting within 4 hours. The strength can reach more than 5Mpa in about 8 hours, and the cast-in-place concrete can be demoulded smoothly. While ensuring the early strength of mortar and concrete, the later strength of mortar and concrete can be increased normally, and it has no destructive effect on other technical properties of mortar and concrete. Scope of application used in ceramic tile binder, cement-based plastering mortar, repair mortar, waterproof mortar, thermal insulation mortar wear-resistant floor and putty and other products, which can improve the compactness of the product and extend the opening time calcium formate is generally not more than 1.2% of the total amount of mortar. calcium formate is incompatible with other additives. it can be mixed evenly with cement, sand and other additives in a mixer according to a certain proportion. |

use | preservative. Has a diuretic effect. EEC countries are allowed to use, but not in the UK. used for leather tanning used as feed additive, suitable for all kinds of animals, with acidification, mildew, antibacterial and other effects calcium formate decomposes free formic acid in animal intestines and stomach, reduces PH in intestines and stomach, is beneficial to activate pepsinogen, promote digestion, and also has antibacterial effect. The addition amount is 1.0%-1.5%. |
