An article to understand the research status of potassium diformate in pig feeding
The pig industry is the mainstay of the livestock industry. In recent years, the demand for pork, poultry and dairy products will increase significantly, and the cost of breeding is also rising. Under the premise of ensuring the ecology, improving quality, increasing efficiency, stabilizing supply, and promoting safety, some feed companies and farmers may hesitate when using new antibiotics to replace the original products. They feel that they are all advocating reality. The effect is simply unknown. Today, we will list a detailed overview of the role of potassium diformate as a new feed additive in place of antibiotics for your reference.
First, there are many studies on potassium diformate as a pig feed additive abroad. Knarreborg, A (2002) studied the effect of potassium diformate on the number of Escherichia coli and lactic acid bacteria in the pH3 gastric juice and pH4.5 small intestinal fluid environment by in vitro method, and found that the addition of potassium diformate inhibited the growth of E. coli and lactobacillus At the same time, the type and concentration of organic acids also affect the test results. Mroz, Z (2002) studied the molecular structure of potassium diformate and its effect on the apparent ileal digestibility and retention of nutrients in growing-finishing pigs, and found that the apparent ileal levels of dry matter, OM, crude protein or essential amino acids in each treatment group There was no difference in digestibility. Only the apparent ileal digestibility of tyrosine increased by 3.9, the fecal digestibility of ash and potassium in each treatment group increased, and the retention of nitrogen, calcium, total phosphorus and potassium in the body of each treatment group difference. Windisch, WM (2001) studied the effects of potassium diformate and excessive copper in different doses and sources on the growth performance of weaned piglets. The addition of potassium diformate and copper increased the daily gain, feed intake and feed conversion rate of piglets.
More literature reports the effects of potassium diformate as an additive on growth performance, digestion and metabolism of piglets. Canibe, N (2001) studied the effect of adding potassium diformate and organic acid to the starter on the acidity and microbial quantity of piglet’s intestinal and gastric juice. The addition of potassium diformate reduced the anaerobic bacteria and lactobacilli in the digestive tract of various segments of the digestive tract. , E. coli and yeast content, but does not affect the pH of the stomach and small intestine.
Paulicks, BR (2000) studied the effect of adding potassium diformate to feeds of different grains and different energy concentrations on the growth performance of weaned piglets. Adding potassium diformate can increase daily weight gain and feed intake to 14 and 9 respectively. In barley and wheat Adding potassium diformate to the barley-wheat-corn mixed diet can increase feed conversion efficiency by 6, 4, and 7, respectively.
Roth, FX (1998) studied the effects of adding potassium diformate in diets with different lysine levels on nitrogen metabolism and nutrient digestibility of piglets. Adding potassium diformate can increase the digestibility of dry matter by 84.0 to 85.0 and crude protein by 80.7 to 82.6, energy 83.5 to 84.7.
Roth, FX (1998) studied the effect of adding potassium diformate to piglets on the absorption of phosphorus, potassium, calcium, magnesium, zinc, manganese, copper and other minerals. The increased amounts were 8 and 9, calcium 2 and 3, and magnesium 3. And 8, zinc 9 and 17, copper 52 and 60, manganese 6 and 6.
Paulicks, BR (1996) studied the effect of different doses of potassium diformate on the performance of growing piglets, and the feed conversion efficiency was also significantly improved.
Blanchard, P (2002) summarized the role of potassium diformate as an antibacterial growth promoter in pig feed, and proposed that potassium diformate is an alternative to pig growth promoter in the post-antibiotic era. Overland, M (2002) also put forward a similar view.
General situation of research and application of potassium diformate in my country:
Beijing Challenge Agricultural Technology Co., Ltd. cooperated with the Feed Research Institute of the Chinese Academy of Agricultural Sciences. Since 2003, it has carried out the research of the synthesis method of potassium diformate under laboratory conditions, choosing formic acid and potassium carbonate as raw materials, and adopting a one-step method to prepare potassium diformate. And according to the amount of potassium formate contained in the primary filtrate, the mother liquor was recycled to make the reaction yield of potassium diformate reach more than 90%, and the product content reached more than 97%. The technical parameters for the production of potassium diformate ( Liang Ping, 2004); established an analytical method for detecting the content of potassium diformate (Shi Bo et al. 2004); and carried out a small production test, product safety evaluation and animal effectiveness test.
The results show that the potassium diformate produced by this synthetic process has the characteristics of high content and good flowability; oral acute toxicity test, inhalation acute toxicity test, subacute toxicity test results show that potassium diformate is a safe feed for animals additive.
The test results of the effect of potassium diformate on the performance of piglets show that adding 1% potassium diformate to the diet can increase daily gain by 8.09% and reduce the feed-to-meat ratio by 9%; adding 1.5% potassium diformate to the diet can Increase the daily weight gain by 12.34%, and reduce the feed-to-meat ratio by 8.16%. It shows that adding 1 to 1.5% potassium diformate in piglet feed can improve piglet performance and feed efficiency. The results of another piglet test showed that: potassium diformate products have no antagonistic effect with antibiotics. The potassium diformate products added to the diet can partially replace antibiotics to promote growth and have a certain synergistic effect with antibiotics in resisting diseases. It has a certain effect in reducing diarrhea and mortality.
Chongqing Chuandong Chemical Group is a formal manufacturer capable of producing feed additive potassium diformate. It is made by mixing patented formic acid and genuine potassium formate, with high content, controllable heavy metals and stable quality.
