The invention discloses an anti-stress anti-diarrhea growth-promotion Chinese herbal medicine feed additive for a weaned pig, which is obtained by carrying out the superfine grinding and mixing on the following components at the mass ratio: 1-5 parts of Astragalus mongholicus, 1 part of Scutellaria baicalensis, 1 part of malt, 1 part of liquorice, 1-5 parts of dangshen, 1-5 parts of poria cocos and 1-5 parts of largehead atractylodes rhizome. According to the Chinese herbal medicine feed additive disclosed by the invention, the weaned pig growth performance can be improved, and the Chinese herbal medicine feed additive has the anti-diarrhea effect; the gastrointestinal tract development of the weaned pig can be promoted; the activity of the digestive enzyme of the gastrointestinal digestive tract of the wigged pig can be improved to promote the development of the pig digestive enzyme system; the micro-ecological environment of the digestive tract of the pig can be regulated and stabilized to accelerate the pig to grow; the antioxidation function of the wigged pig organism can be improved so as to improve the compensatory capability of the wigged pig organism on external irradiation; the intestinal mucosa form of the wigged pig can be improved so as to alleviate the intestinal villus withering of the wigged pig and promote the tract of the wigged pig to restore; and the immunologic function of the intestinal mucosa of the wigged pig can be regulated.

The invention discloses a lactobacillus reuteri 22 and application thereof. The lactobacillus reuteri 22 disclosed by the invention is separated from healthy chicken flocks, is classified and named aslactobacillus reuteri, and has a preservation number of CGMCC No.17932. By detecting the performance of probiotics, the invention finds that the lactobacillus reuteri 22 has good acid resistance, cholate resistance and adhesion performance, and can inhibit growth of pathogenic bacteria. Through Animal assays, in a healthy physiological state, the lactobacillus reuteri 22 does not influence the level of inflammatory factors, but can increase the number of goblet cells and promote the increase of expression levels of related genes such as compact protein, defensin and lysozyme, can increase thelength of intestinal villi and the depth of crypt, and has the potential of maintaining intestinal mucosa barriers. Therefore, the strain is expected to be developed into probiotics for maintaining achicken intestinal mucosa barrier and guaranteeing green and healthy chicken breeding.

The invention discloses a diet starch source combination capable of improving health of intestinal tracts of piglets. The ratio of amylose to amylopectin is 0.48, so that the concentration of total short chain fatty acids, particularly the concentration and the molar ratio of butyrate, of contents in cecum and colon of a piglet can be increased, and accordingly maintaining of completeness and functions of enterocyte of hindgut of the piglet is facilitated. After the piglet is fed by feed containing the amylose and the amylopectin with the ratio of 0.48 for a long time, the gastro-intestinal morphology and the intestinal enzyme activity of the piglet can be improved, the height of intestinal villus is increased, the depth of a crypt is increased, accordingly, growth and development of the small intestine of the piglet can be promoted, and the gastro-intestinal morphology structure is improved. As a starch source with the ratio of the amylose to amylopectin to be 0.48 is used as a daily feed energy source, health of the intestinal tracts of the piglet is possibly facilitated, and development of later-period production performance of the piglet is also facilitated.

The invention discloses a polypeptide and application thereof. The polypeptide contains continuous amino acid residue fragments with sequences of Pro-Gly-Ala-Asp or Asp-Ala-Gly-Pro. The polypeptide can be synthesized according to sequence structures by the aid of a polypeptide synthesizer and also can be extracted from natural plants including radix notoginseng, flos sophorae, aloe vera and\or rhizoma bletillae. The polypeptide and the application have the advantages that effects of promoting migration of stem cells and vascular progenitor cells of mice and directionally differentiating the stem cells and the vascular progenitor cells towards vascular endothelial cells can be realized by the polypeptide, and accordingly damage repair of the vascular endothelia cells and formation of new blood vessels can be promoted; skin spray can be prepared from the polypeptide, wound healing can be promoted by the skin spray, and inflammation can be prevented and treated by the skin spray; oral liquid for piglets can be prepared from the polypeptide, regeneration and repair of intestinal villi of the piglets can be promoted by the oral liquid, and accordingly diarrhea diseases of the piglets can be fundamentally prevented and radically treated by the oral liquid; feed additives for animals can be prepared from the polypeptide, and effects of resisting diarrhea and promoting growth can be realized by the feed additives; perfusion agents for the uteruses of sow can be prepared from the polypeptide, quick healing of postpartum wound of the sow can be promoted by the perfusion agents, and inflammation of the sow can be effectively prevented and treated by the perfusion agents.

The invention discloses a plant extract additive for improving intestinal health of livestock and poultry, and belongs to the field of feed additives. Intestinal tracts are digestion and absorption places of livestock and poultry nutrient substances, intestinal tract damage certainly causes diarrhea, diarrhea and the like, the phenomena of low feed conversion rate, reduced growth performance and the like are caused. The plant extract additive comprises the following main components: 10-30 parts of a plant essential oil compound, 10-30 parts of plant polysaccharide, 10-20 parts of medium and short chain fatty acid and 50-70 parts of a carrier, wherein the plant essential oil compound is prepared by mixing one or more of cinnamyl aldehyde, thymol, carvacrol, eugenol and allicin according to a specific proportion; the plant polysaccharide is prepared by mixing one or more of astragalus polysaccharide, ganoderma lucidum polysaccharide and gingko polysaccharide according to a specific proportion; and the medium and short chain fatty acid is prepared by mixing one or more of caprylic acid, capric acid and lauric acid according to a specific proportion. Breeding test results show that the plant extract compound feed additive has the functions of obviously improving intestinal flora structures of the livestock and poultry, promoting intestinal villus development and the like besides remarkable anti-inflammation and sterilization effects. The feed additive has the characteristics of wide antibacterial spectrum, difficulty in generating drug resistance, no pollution to the environment and the like, can effectively kill harmful bacteria in intestinal tracts of livestock and poultry, also has the effects of promoting intestinal villus development, intestinal barrier repair and the like, improves the digestion and absorption of organisms on nutrient substances, enhances the disease resistance of flora and improves the breeding benefits of the livestock and poultry.

The invention provides a nutritional prophylactic for turbot enteritis. The nutritional prophylactic contains 20%-30% by mass of mannan oligosaccharide and 70%-80% by mass of sodium butyrate. The invention further provides an application of the nutritional prophylactic to preparation of turbot feed. The nutritional prophylactic for turbot enteritis is used before feeding with feed containing turbot enteritis-inducing anti-nutritional factors and plant protein sources, and can remarkably reduce occurrence of turbot enteritis. Specifically, the nutritional prophylactic can remarkably increase intestinal villus height, reduce intestinal villus adhesion, reduce infiltration of inflammatory cells on lamina propria and submucosa and increase vacuoles absorbed on epithelia cell nuclei. Compared with antibiotics for treatment, the nutritional prophylactic for turbot enteritis is safer and more reliable.
