Sodium butyrate is an organic compound with molecular formula of C4H7O2Na and molecular weight of 110.0869. The appearance is white or almost white powder, with special fat odor like cheese rancidity, and hygroscopic. The density is 0.96 g/mL (25/4 ºC), the melting point is 250~253 ºC, and it is easily soluble in water and ethanol.
purpose
1. Maintain beneficial microbial flora in the gastrointestinal tract. Butyric acid inhibits the growth of harmful bacteria through the cell membrane, promotes the growth of beneficial bacteria in the gastrointestinal tract, and keeps the gastrointestinal microecology in a positive balance;
2. Provide fast energy source for intestinal cells. Butyrate is the preferred energy of intestinal cells. Sodium butyrate is absorbed in the intestinal cavity and can rapidly provide energy for intestinal epithelial cells through oxidation;
3. Promote the proliferation and maturation of gastrointestinal cells. The digestive tract of young animals is imperfect, the villi and crypts of small intestine are immature, and the secretion of digestive enzymes is not enough, resulting in poor nutrient absorption capacity of young animals. The experiment shows that sodium butyrate is an activator to increase the proliferation of intestinal villi and the depth of crypt, and can expand the absorption area of large intestine;
4. Effect on animal production performance. Sodium butyrate can improve feed intake, feed remuneration and daily weight gain. Improve animal health. Reduce diarrhea and mortality;
5. Promote the function of non-specific immune system and specific immune system;
6. The special smell has a strong attraction to young pigs and can be used as a food attractant; It can be added to various feeds to improve daily weight gain, feed intake, feed conversion rate and economic benefits;
7. Reduce the release of intracellular Ca2+. Inhibit histone deacetylase (HDAC) and induce cell apoptosis;
8. Promote the development of intestinal mucosa, repair mucosal epithelial cells and activate lymphocytes;
9. Reduce post-weaning diarrhea of piglets, overcome weaning stress, and improve the survival rate of piglets.
