The performance performance of sows directly affects the efficiency of raising pigs. In China, both large-scale pig farms, medium-sized and small-scale pig farms, or professional fish farmers, the sow has low levels of production performance, such as constipation and insufficient body condition. Not estrus, delayed estrus, estrus or estrus is not obvious, less milk secretion. Once the sow is pregnant, progesterone secretion will continue to increase, especially in late pregnancy, in order to reduce contractions of the uterine smooth muscle to maintain pregnancy. Progesterone can slow down the contraction of smooth muscle (including uterus and gastrointestinal smooth muscle, etc.), so intestinal motility will be greatly reduced, intestinal digestive function will also be greatly reduced, plus the fetus continues to increase, squeeze the stomach The intestines eventually cause the feces to be too long in the intestine, and the large intestine absorbs too much water and the feces is dried up, like abacus beads. In addition, placenta of pregnant sows can secrete chorionic gonadotropin after pregnancy. This hormone can inhibit the secretion of gastric acid. If stomach acid is not enough, the activity of digestive enzymes in the stomach will be reduced. At the same time, it will also affect the digestion and absorption function of stomach acid, so the sows will show appetite. Falling, unwillingness to exercise, drowsiness and other early pregnancy reactions, these will affect the development of the fetus and even cause dystocia, resulting in greater losses to the farm. Acid preparations can improve the flavor of the feed, mask the bad odor in the feed due to the addition of minerals and vitamins, increase the sow's feeding interest, and supplement the lack of gastric acid secretion caused by pregnancy. But adding unprotected acid to the sow's feed will release all of the acid in the stomach, which in turn will inhibit the ability of the sow to secrete acid. In order to improve the constipation and loss of appetite that may occur during pregnancy, the sow must also use protective acid agents. The protective acidifier after special processing can effectively reduce the release of the acid preparation in the anterior part of the digestive tract, especially the stomach, so as not to cause the repressive inhibition of gastric acid secretion; the protective acid preparation is mainly released in the posterior segment of the digestive tract and Play a role, in particular to inhibit the growth of harmful bacteria in the posterior segment of the digestive tract and promote the growth of beneficial bacteria. It can be seen from Table 2 that the pH value of the ileal chyme increases with the addition of a protective acidifier to the diet over time. Gradually decreased, the rate of decline on the first day after eating was the largest and fell to the lowest point after 3 days, and then there was an upward trend. By reducing the pH of the chyme in the mid- and post-intestinal tract, the growth of harmful bacteria is reduced, Thomas (2002). Protective acidifiers can also significantly reduce the number of E. coli in the gut, and Ravindran (1993) suggests that protective acidifiers can reduce the number of pathogenic E. coli in feces more than acidifiers without any treatment. The number of harmful bacteria in the posterior segment of the intestine will decrease, and beneficial bacteria will increase. The digestion and absorption capacity of the intestine will be greatly increased, thereby reducing the possibility of constipation and increasing the lactation during sow feeding.
