Pathogenic bacteria such as Escherichia coli, Staphylococcus and Streptococcus are suitable for growth in the intestine at a pH of 6.0-7.0, and at pH #4, they are substantially inactivated. The optimal growth environment of lactic acid bacteria as a beneficial bacteria in the intestine is PH3.0-4.5. The proliferation of lactic acid bacteria further reduces the pH value of the gastrointestinal tract, providing a suitable internal environment for the digestion and absorption of the diet. At the same time, it inhibits the proliferation of harmful bacteria, reduces the morbidity and mortality of piglet diarrhea, and improves the disease resistance rate of piglets, thereby reducing the respiratory diseases in the later stage. gGF China Feed Industry Information Network - based on feed, serving animal husbandry

In addition, according to the nutritional and physiological characteristics of piglets, acidifiers should be added in nursery houses, because piglets have unique physiological characteristics compared with adult pigs: gGF China Feed Industry Information Network - based on feed, serving animal husbandry

First, the digestive system of newly weaned piglets is not well developed. Except that the volume and weight of the digestive tract and digestive gland have not reached maturity, its fine structure is not fully developed. Generally, piglets have problems of insufficient secretion of endogenous enzymes. The main function of the source enzyme is to digest lactose in the breast milk, simple fat, protein and other substances, and the enzymes necessary for digesting the diet are synthesized only a few weeks after birth. gGF China Feed Industry Information Network - based on feed, serving animal husbandry

Second, the birth of piglets has less gastric acid secretion and lacks free hydrochloric acid. Generally, piglets secrete a small amount of hydrochloric acid from the age of 20 days, and then increase with the increase of the diet. Before weaning, the piglets mainly absorb breast milk, and the environment of the gastrointestinal tract is relatively stable. The lactose in the breast milk can be converted into lactic acid by the lactic acid bacteria in the stomach. After the second weaning, the lack of gastric acid secretion can often lead to an increase in the pH value of the gastric juice, which affects the digestion and absorption of the piglet diet. gGF China Feed Industry Information Network - based on feed, serving animal husbandry

Improper use of acidifier can also cause damage to the stomach of piglets, causing ulceration of the fundus, because if the acidifier is not directly applied to the stomach, the acidity will be too high, but it will inhibit the secretion of gastric acid, but it will not have effect, but instead The stomach has irritation. gGF China Feed Industry Information Network - based on feed, serving animal husbandry
