Description

Weaned piglet creep feed with immunity enhancing and diarrhea resisting functions and preparation method thereof Technical Field The invention belongs to the technical field of pig feeds, and relates to an immunity-enhancing anti-diarrhea weaned piglet creep feed and a preparation method thereof. Background In modern large-scale pig raising production, healthy growth of piglets plays a vital role in the whole raising benefit. The creep feed is used as a key diet for piglets to transition from breast milk to solid feed, and the quality of the creep feed is directly related to the growth performance, the immunity performance and the intestinal health condition of the piglets. The intestinal tract and immune organs of the piglets at the weaning stage are imperfect in development, low in immunity and easy to be influenced by various stress factors, so that diseases occur, diarrhea rate and death rate are increased, and huge economic losses are brought to the pig industry. Coli K88 is used as an important serotype of enterotoxigenic escherichia coli (ETEC), can be specifically adhered to the surface of small intestinal epithelial cells, and can generate enterotoxigenic, destroy the normal physiological functions of intestinal tracts and cause diarrhea of piglets. In the actual pig raising environment, piglets are extremely easy to be infected with escherichia coli K88, and diarrhea is serious. Egg yolk antibodies have recently received attention as a specific immunoglobulin in the field of animal disease control. The yolk antibody of the targeted escherichia coli K88 can specifically identify and bind to an antigen site on the surface of the escherichia coli K88, so that the colonization and propagation of the escherichia coli K88 in the intestines are effectively inhibited, and the risk of diarrhea caused by piglet infection is reduced. The yolk antibody has the advantages of wide source, relatively simple preparation, good stability and biological safety, and no drug resistance and drug residue. In addition, in recent years, as natural plant extracts are being studied in the field of animal nutrition, polysaccharides have been attracting attention due to their green, safe and multifunctional properties. The sweet wormwood polysaccharide has remarkable immunoregulatory activity, can enhance the nonspecific immunity of organisms, and has the antioxidation characteristic of relieving the intestinal oxidative damage of weaned pigs. Inulin polysaccharide is used as a high-quality prebiotic, can stimulate the proliferation of intestinal probiotics, strengthen the barrier function of intestinal tracts and reduce the colonization of pathogenic bacteria. The Salvia polysaccharide has antiinflammatory and tissue repair promoting effects, and can relieve intestinal inflammatory reaction. At present, the existing creep feed in the market mostly adopts single components or simple composite additives in the aspect of coping with the intestinal health and immunity improvement of weaned pigs, and is difficult to solve the complex problems facing the piglets from multi-dimensional synergy. Therefore, the egg yolk antibody, the sweet wormwood polysaccharide, the inulin polysaccharide, the salvia polysaccharide and the like of the targeted escherichia coli K88 are applied to the immunity-enhancing anti-diarrhea creep feed, so that the quality of the creep feed is improved, and the healthy growth of piglets is guaranteed. Disclosure of Invention In order to solve the problems, the invention provides an immunity-enhancing anti-diarrhea piglet creep feed formula, which comprises, by weight, 18-30 parts of puffed corn, 10-20 parts of broken rice, 6-10 parts of puffed soybean, 5-8 parts of flour, 3-5 parts of fermented soybean meal, 3-6 parts of puffed flaxseed, 8-12 parts of soybean milk powder, 3-6 parts of whole milk powder, 5-8 parts of fish meal, 1-3 parts of chicken liver powder, 5-8 parts of glucose, 0.6-1.0 part of calcium hydrophosphate, 0.6-1.0 part of L-lysine hydrochloride (98.5%), 0.1-0.2 part of DL-solid methionine, 0.1-0.3 part of compound vitamin and 2-5 parts of creep feed core material. Preferably, the piglet creep feed formula comprises, by weight, 20 parts of puffed corn, 18 parts of broken rice, 8 parts of puffed soybean, 6 parts of flour, 4 parts of fermented soybean meal, 4 parts of puffed flaxseed, 10 parts of soybean milk powder, 5 parts of whole milk powder, 5 parts of fish meal, 2 parts of chicken liver powder, 7 parts of glucose, 0.7 part of calcium hydrophosphate, 0.8 part of L-lysine hydrochloride (98.5%), 0.2 part of DL-solid methionine, 0.1 part of compound vitamin and 4 parts of creep core material. Preferably, the compound vitamins comprise vitamin A, vitamin D3, vitamin E, vitamin K, vitamin B12, vitamin B1, vitamin B2, vitamin B6, nicotinic acid, D-pantothenic acid, folic acid and biotin, and the proportion is 12000 IU:1200 IU:30 IU:2.5 mg:100 mug to 3 mg:10 mg:8 mg:30 mg:60 mg:1.5 mg:0.4 mg.
