Problems solved by technology

[0003] Flavomycin, an antibiotic growth promoter, inhibits the reproduction of bacteria by interfering with the biosynthesis of peptidoglycan, a structural substance of the cell wall, but its extensive use in the feed industry has led to many problems, such as drug resistance of pathogenic bacteria, animal immunity Decreased function, imbalance of flora in the body, drug residues in livestock and poultry products, etc.

Abstract

The invention discloses a compound feed for adjusting the intestinal development of piglets. The compound feed comprises the components: 61-65 parts of corns, 15-20 parts of bean pulp, 3-6 parts of whey powder, 5-10 parts of fish meal, 1-3 parts of glucose, 0.1-0.5 part of an acidifying agent, 0.5-1 part of calcium hydrogen phosphate, 0.5-1 part of limestone powder, 0.1-0.5 part of table salt, 0.1-0.5 part of L-lysine hydrochloride, 0.1-0.5 part of DL-methionine, 0.1-0.5 part of threonine, 1-4 parts of a piglet premix feed, 0.05-0.5 part of an aloe polysaccharide additive and 0.05-0.5 part of sodium butyrate. After weaned pigs are fed by the compound feed for four weeks, the influence of the feed formula to the development of intestinal microflora biota and intestine mucosa can be discussed. The results prove that in an experimental group, the quality of lactobacillus in the duodenum, the middle section of the jejunum and the ileum as well as the total quantity of aerobic bacteria in the middle section of the jejunum is remarkably increased, the villus heights of the duodenum, the middle section of the jejunum and all the sections of the ileum is remarkably increased, and the crypt depths of the duodenum, the middle section of the jejunum and the ileum is remarkably reduces. Therefore, after the aloe polysaccharide and the sodium butyrate with the appropriate proportion are added into the feed for the weaned pigs, the compound feed has the function of obviously improving the intestinal health, and the experimental group has the effect superior to a flavomycin group and a comparison group.

Description

technical field [0001] The invention belongs to the field of animal nutrition technology research in animal husbandry, and relates to a feed formula using aloe polysaccharide and sodium butyrate as feed additives, more specifically, a method for improving the microflora of intestinal content of weaned piglets and promoting the development of intestinal mucosa and other applications. Background technique [0002] In recent years, animal husbandry has received more and more attention in terms of ensuring animal health, promoting animal growth, and improving feed utilization. The research on feed additive aloe polysaccharide and antibiotic substitute sodium butyrate is moving towards no residue, no drug resistance and Develop in a direction that is harmless to human health and the environment. Feed additive aloe polysaccharide is widely used in animal production because of its unique naturalness, multipotency, less toxic and side effects, and less drug resistance. It is rich ...
