The invention relates to an environment-friendly chick immunopotentiator. The environment-friendly chick immunopotentiator is prepared by mixing morida officinalis how polysaccharide, gamma-aminobutyric acid, arginine, taurine and lysine uniformly, wherein the morida officinalis how polysaccharide is prepared by extracting morida officinalis rootstock by the conventional water extraction and alcohol precipitation method. The environment-friendly chick immunopotentiator has a simple preparation process, scientifically combines South China medicine morida officinalis how polysaccharide and amino acid such as GABA, effectively promotes improvement of the growth performance and the immune function of the chicks and enhances the immune function of the chicks; the immunization time is long; the preparation is simple in composition; the materials are easy to obtain; various components belong to safety components; the problems of medicine residues, toxic or side effect and the like are avoided; and the environment-friendly chick immunopotentiator is environment-friendly, efficient and stable.

The invention provides a poultry immunopotentiator. The poultry immunopotentiator comprises a fermentation product of inonotus obliquus which is preserved in the China General Microbiological CultureCollection Center with a preservation number of CGMCC No.14549. Adding amount, in poultry feed, of the fermentation product of the inonotus obliquus is 0.2-2wt%; and adding amount of poultry drinkingwater is 0.1-5wt%. The inonotus obliquus fermentation product is used to feed the poultry, so that immune organ growth, non-specific immune response and specific immune response of the body can be remarkably improved; and immune organ indexes are increased, non-specific immune related indexes are increased, peripheral blood lymphocyte proliferation and differentiation ability is improved, antibodyand neutralizing antibody titer is increased, content of cell factors is increased, so that a novel tool is provided for preventing and controlling poultry diseases.

The invention provides a compound biological feed additive for laying hens, which belongs to the technical field of feed science and feed additives. The feed additive of the invention comprises: feed-grade fulvic acid, insect meal, fermented insect excrement, extract compound preparation, microbe Ecological preparations and carriers are compounded according to a certain proportion. The premix of the compound biological feed additive is used in the feed of laying hens, which can not only regulate the internal environment of the digestive tract of livestock and poultry, regulate the balance of the intestinal flora of the body, enhance the immune function of the body, and has the functions of antibacterial, anti-stress, enhancing immunity, improving In terms of production performance, the feed additive of the present invention is added to the diet of laying hens to improve the production capacity and self-immunity of laying hens, improve the feed conversion rate, thereby reducing drug residues and improving the quality of eggs. It is a new type of safe, reliable, green and environmentally friendly feed additive product. , the application prospect is good.

The invention provides a preparation and use method of a royal paulowinia flower polysaccharide traditional Chinese medicine immunoenhancer. Polysaccharide is extracted from royal paulowinia flower medicine materials to prepare the traditional Chinese medicine immunoenhancer. A 18-day-old non-immunized chicken is taken, a nose and eyes of the chicken are dropped by a newcastle disease vaccine IV,so that the chicken is firstly immunized, the chicken is secondly immunized when growing for 32 days, the chicken is drenched once every one day with royal paulowinia flower polysaccharide solution through a mouth when the chicken is immunized every time, the administration dosage is 12.5-50mg / kg, and the chicken is continuously drenched with the royal paulowinia flower polysaccharide solution forthree days, measurement is performed on the seventh day, fourteenth day, twenty-first day and twenty-eighth day after the chicken is firstly immunized, results discover that royal paulowinia flower polysaccharide can obviously facilitate appreciation of peripheral blood and splenic lymphocytes of the chicken, ND-HI antibody level is improved, immune organ indexes are improved, the concentration of cell factors such as IL-4, IL-6 and IFN-g in serum is improved, the content of duodenum SIgA is improved, so that immunity of a body is improved, and the immune effect of a vaccine is enhanced.

The invention discloses an antibiotic-free daily feed additive premix for a broiler chicken and using method of the antibiotic-free daily feed additive premix. The premix is prepared from 10-20% of curcumin, 5-15% of alpha-galactosidase, 5-15% of yeast cell wall polysaccharide, 5-15% of clostridium butyricum, 5-15% of bacillus licheniformis and 20-70% of a carrier. Due to a combined effect of the curcumin, the alpha-galactosidase, the yeast cell wall polysaccharide, the clostridium butyricum and the bacillus licheniformis, the premix regulates the body immunity and the disease resistance of the broiler chicken, improves the breeding performance of the broiler chicken, improves the utilization rate of nutrients in a daily ration of the broiler chicken and stimulates the growth potential of the broiler chicken, so that a significant effect is achieved. Animal experiments prove that the premix can effectively substitute antibiotics, so that toxic and side effects such as drug resistance, drug tolerance, drug residue and the like, which are caused by long-term use of the antibiotics, are avoided, and healthy and sustainable development of breeding industry and feed industry can be promoted.
