Yeast derived biological feed helps non resistant feed and healthy breeding

1、 Yeast is widely used in all walks of life. Yeast is the only microbial product with an annual output of more than one million tons, and yeast can be widely used in all walks of life according to the different needs of different industries and combined with the different characteristics of yeast. In terms of fermentation, yeast has characteristics that other microorganisms do not have: first, it has fast reproduction, vigorous metabolism, and rich nutrition. Secondly, yeast is a facultative microorganism, which can grow under aerobic or anaerobic fermentation conditions. Anaerobic fermentation can obtain metabolites (alcohol, various wines, glycerol, enzymes, etc.), and aerobic fermentation can obtain yeast cells or cell components. Third, the energy required for the growth and reproduction of yeast mainly comes from the catabolism of sugars. A variety of different monosaccharides and oligosaccharides, non carbohydrates (such as polyols, petroleum lyates), carbon sources in industrial growth (such as molasses, corn, barley and other cereals, sugar containing waste liquid, sulfite waste liquid, etc.) can be used by yeast to realize transformation. In terms of nutrition, the protein content of yeast is about 50%, and the amino acid content is complete; Rich in B vitamins; The content of nucleic acid (RNA) in common yeast is 6-8%, and that in high nucleic acid yeast species is 12-14%; Yeast metabolites are rich in enzymes and physiologically active substances. 2、 Yeast industry in the feed industry in the domestic feed industry, yeast products have been used for nearly 20 years. The functions of yeast used are mainly reflected in the following eight aspects: (1) as a probiotic, it regulates the intestinal microflora of animals; (2) As a feed fermentation agent, improve the nutritional value of feed; (3) Yeast conducts bioconcentration and transformation of inorganic trace elements to produce organic trace element products; (4) Yeast is rich in nutrition, and the yeast hydrolysate obtained by enzymatic hydrolysis is used as a functional protein raw material in feed formula; (5) Yeast glucan can effectively stimulate the immune system; (7) As a prebiotic, yeast mannan oligosaccharide can promote the growth of beneficial microorganisms and inhibit the reproduction of harmful microorganisms, and can be used as a mycotoxin adsorbent; (8) Yeast can be used as bacteriostasis and growth promoter. 3、 How yeast products can play a role in non Anti Japanese grain, the rise in the price of protein raw materials, and the rehabilitation of pigs? High quality nutritional composition --- yeast hydrolysate 5-40 kg / ton full price material; Yeast hydrolysate is a high-quality functional protein raw material. Adding yeast hydrolysate to non Anti Japanese food can reduce the use of plant protein raw materials, thus reducing the nutritional diarrhea of suckling pigs. Yeast is the fermentation agent of feed raw materials. In the fermentation of soybean meal, the elimination rate of raffinose and stachyose is ≥ 99%, and the elimination rate of soybean globulin is ≥ 70%. Reduce respiratory diseases. Adding yeast to non Anti Japanese grain can improve the digestibility and utilization of feed for pigs, so as to reduce the emission of fecal sewage and ammonia, and reduce the incidence of respiratory diseases. In order to cope with the rise in the price of fish meal, 1.0-1.5% of gaopenuo can be added to the lactating sow feed, 1:1 to replace fish meal (it is recommended to add salt in the formula, which has better feeding attractiveness). After adding, the feeding is higher, the milk is better, the piglets are healthier, and the fat loss is less. Adding yeast hydrolysate of 1.0-2.0% to the conservation material and substituting fish meal by 1:1 will result in faster growth, lower weight gain cost and better breeding benefit. In view of the rising price of soybean meal, we can adopt the method of making low protein diet to deal with it. The healthy growth of piglets under low protein diet was achieved by adding yeast hydrolysate. High purity yeast mannan oligosaccharide, fully soluble in water, can be added not only in the diet, but also in the water line of the breeding site. As a kind of yeast prebiotic, it can promote the growth of probiotics in the gastrointestinal tract of sows, reduce the reproduction of pathogenic bacteria, reduce the occurrence of constipation in sows, and enhance the immunity of sows. Yeast selenium, as the only general organic selenium source, can deposit in muscle tissue and organs, resist stress and improve reproductive function. The wide application of yeast derived biological feed, on the one hand, shows that the changes in the feed industry have promoted the continuous iteration and upgrading of yeast products, on the other hand, it also confirms that the yeast industry has played an important role in promoting the development of the feed industry. With the development of feed industry, yeast industry will better serve feed industry in the future< Br/> first, understand the feed antibiotics 1. The classification of feed antibiotics 2. The antibacterial mechanism of antibiotics 3. At present, there are no major solutions for anti breeding ① feeding management ② environmental purification ③ feed structure adjustment ④ mycotoxin control ⑤ raw material control; ⑥ Rational use of drugs ⑦ antibiotic substitutes 4 problems after the prohibition of antibiotics ① living yeast: intestinal flora disorder, diarrhea, dyspepsia, feed stool ② yeast cell wall: low immunity, increased susceptibility, diarrhea, increased dead Amoy rate ③ yeast hydrolysate: intestinal injury, low feed utilization rate, decreased growth performance ④ yeast essence: outbreak of intestinal pathogenic bacteria, bacterial disease complicated II Research progress in the application of non antibiotic yeast products 1. Promote intestinal development: yeast hydrolysate (both nutritional and functional) 2. Regulate intestinal flora: live yeast 3. Regulate the immune system: yeast cell wall, semi replace kitasamycin and colistin sulfate 4. Inhibit the reproduction of harmful bacteria: yeast essence (broad-spectrum bacteriostasis)   3、 Outlook: the development trend of yeast products under the background of no resistance. Yeast products are the inevitable choice under the background of no resistance. 1. No potential biosafety hazards. 2. Technically, it can realize 3 advantages of industrialized production 4 sustainable technological upgrading
