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. Experiments have shown that adding citric acid to the diet of piglets has the following benefits. First, reduce the gastrointestinal pH value of piglets, 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 propagation of lactic acid bacteria, and inhibit the growth of E. coli and Staphylococcus. Adding 0.7% and 1% citric acid to the diet of 42-day-old pigs reduced the pH of gastric contents from 4.5 to 4.2 and 3.5, respectively, and significantly reduced the number of colonic and rectal E. coli strains. . At the same time, a large number of lactic acid bacteria and yeasts can effectively prevent digestive disorders and diarrhea caused by bacterial infections. Second, improve diet palatability and promote growth of piglets. 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. Third, directly as a dietary ingredient to promote piglet metabolism. 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 the diet to reduce the loss of piglets due to gluconeogenesis and lipid hydrolysis. The synthesis of ATP in vivo 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. Fourth, prevent feed oxidation, 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.
