Adding citric acid to the plant protein-based diet before the piglets weigh up to 30 kg can effectively improve the digestibility of the feed and the performance of the piglets. Most tests have shown that the addition of 1% to 2% citric acid to diets has a good effect in preventing the occurrence of diarrhea in piglets, promoting growth of piglets, and improving feed conversion. Reduce the intestinal pH of piglets and reduce the incidence of diarrhea. Citric acid can reduce the pH of the diet, increase the acidity and digestive enzyme activity of the gastrointestinal tract, promote the proliferation of lactic acid bacteria, and inhibit the growth of E. coli and Staphylococcus. The addition of 0.7% and 1% citric acid to the 42-day-old pig diet reduced the pH of the gastric contents from 4.5 to 4.2 and 3.5, respectively, and significantly reduced the colonic and rectal E. coli counts. . At the same time, a large number of lactic acid bacteria and yeasts can effectively prevent digestive disorders and diarrhea caused by bacterial infections. Improve diet palatability and promote piglet growth. According to experiments, the addition of 1% to 2% citric acid to the diet can increase the feed intake of piglets by 5.2% to 19.8%, the daily gain of piglets by 9% to 38.67%, and the feed conversion rate by 11% to 15%. And adding citric acid is better than adding other organic acids. Regulate the speed of gastric emptying and promote the digestion and absorption of nutrients. After adding 1% citric acid to the diet of piglets, the pH in the stomach and intestine decreases, and the acidic chyme enters the small intestine and passes through chemical stimulation of the small intestine to secrete intestinal ghrelin, slowing the rate of gastric emptying. The speed of food movement in the intestine extends the food's residence time in the stomach, allowing the food to be fully mixed with saliva, gastric juice, and other digestive fluids, which is beneficial to the digestion and absorption of nutrients in the food. At the same time, citric acid can form the chelates that are easily absorbed and utilized and have high biological valences with the essential mineral elements such as Ca, Cu, Fe, P, Zn, and Mg of piglets to promote their absorption and retention. The main reason is that some mineral elements in the alkaline gastrointestinal tract easy to form insoluble and difficult to absorb salts, and citric acid can reduce the intestinal pH, promote the absorption and utilization of fat in the feed minerals. Directly used as a dietary ingredient to promote metabolism of piglets. Citric acid is an important component of food, protein and fat metabolism, and is an intermediate product of the TCA cycle. The released ATP can act as a dietary component. Citric acid is added to diets to reduce the loss of piglets due to gluconeogenesis and lipid hydrolysis. The synthesis of ATP in the body promotes the activity of the electron transport system and isocitrate dehydrogenase, the formation of ATP, and biological activity. The accumulation of total amounts plays an important role in promoting the metabolism of piglets and increasing the utilization of energy and amino acids in piglets. Prevent feed oxidation and reduce weaning stress. Citric acid is a synergist for feed antioxidants. Its mechanism of action is to block the metal ions in the feed, so that it can not act as a catalytic oxidation reaction. At the same time, as the early weaned piglets have less feed intake, they have lower utilization rates of sugar and protein feeds, and have higher incidence and mortality of diarrhea. Citric acid in feed can promote the secretion of gastric juice and digestive enzymes and effectively overcome piglets Weaning stress. China Agricultural Network Editor
