Acidifying agent added to piglet feed is effective
At present, acidifiers have been widely used by developed countries in the world of animal husbandry, and domestic acidifiers have also been increasingly emphasized and widely used by animal husbandry workers and farmers. Feed acidifiers include inorganic acids, organic acids and their salts. The feed acidifiers marketed are mostly compound acidifiers that combine the advantages of organic acids and inorganic acids. The addition of acidifiers to the feed of piglets can significantly increase feed intake and daily gain of piglets, reduce the feed-to-meat ratio, reduce disease (especially piglet diarrhea), and slow stress responses. First, the mechanism of action of acidifier 1, lower diet and stomach pH, ​​increase enzyme activity, regulate gastric emptying speed, promote protein breakdown, protein decomposition can stimulate the duodenum to secrete more trypsin, So that the protein completely decomposes and absorbs. 2. Regulate the gastrointestinal microflora by lowering the pH of the gastrointestinal tract. Escherichia coli, streptococcus, staphylococcus and other pathogens are suitable for the neutral alkaline environment, and lactobacillus and other beneficial bacteria are suitable for the acidic environment. Therefore, the acidifier can inhibit the reproduction of harmful microorganisms, reduce the consumption of nutrients, and the production of anti-growth toxins while promoting the proliferation of beneficial bacteria. In addition, organic acids also have a strong bactericidal effect. 3. Some organic acids are important intermediates in the energy conversion process and can directly participate in metabolism as the energy component of the diet. 4. Organic acids can chelate with calcium, phosphorus and other mineral elements, and promote the absorption of mineral elements. 5. It can improve the palatability of the diet and increase the intake of piglets. Second, the effectiveness of piglets diet supplement acidifiers piglets secretion of gastric acid is very low, the stomach PH value of more than 4.2, but the piglet feed PH value of more in between 5.8-6.5, often making the stomach PH value is too high Causes piglets indigestion, diarrhea and slow growth. Tests have shown that the addition of acidifiers is beneficial to improve the performance of piglets, generally increasing the daily gain and feed conversion efficiency by 4-27% and 3-15%, respectively. It has been reported that adding 3% citric acid to piglet diets increases daily weight gain, feed intake, and feed conversion by 14%, 14%, and 6%, respectively; adding 0.2% Ultrac Lac 8 Dry (mainly containing large amounts of lactic acid And other organic acids), pig feed intake, daily gain increased by 12.2% and 17.2%, respectively, and the incidence of diarrhea decreased by 92.7%. Third, the use of acidifiers Note 1, the addition of acidifiers in piglets after weaning 30 kg body weight before the effect is obvious, and 30 kg after the effect is not obvious. 2. Acidifiers are more effective in diets dominated by plant proteins, whereas effects added to animal protein-rich diets are often insignificant. 3, inorganic acid should not be added. The addition of inorganic acids often does not improve the production performance and even reduces the production performance. 4. The effect of propionic acid in organic acids is poor. Butyric acid and malic acid have a negative effect. Citric acid, fumarate, and calcium formate are effective, and the amount added is generally 1-3%.
