The invention belongs to the field of aquaculture or feed, relates to a aquaculture feed, and especially relates to an alga immunopotentiation compound feed for litopenaeus vannamei. The invention at first provides an immunity strengthening agent for litopenaeus vannamei feed, and the agent is obtained through enzymatic hydrolysis and fermentation of an alga composite. The alga composite is composed of following components in parts by dried weight: 40 to 50 parts of asparagus, 15 to 25 parts of enteromorpha, 10 to 20 parts of ulva lactuca, 5 to 15 parts of laver and 5 to 15 parts of undaria pinnatifida. The invention further prepares a compound feed for litopenaeus vannamei by utilizing the immunity strengthening agent. The alga immunity strengthening agent contains algae polysaccharide, which has the effect of strengthening animal immunity, acrylic acid, terpenes, brominated phenolic and some sulfocompounds, which have the antiseptic effect, and sulphated polysaccharide, which has the antivirus effect. The litopenaeus vannameis fed on the alga immunopotentiation compound feed have a strong anti-stress performance, the body's immunity ability is improved, survival rate is high and culture benefit is remarkable.

The invention relates to a rice wine beverage for tonifying kidney and a preparation method thereof and relates to the rice wine beverage and the preparation method thereof. The rice wine beverage is prepared from the raw materials of glutinous rice, prepared rhizome of rehmannia, cinnamomvine, common macrocarpium fruit, Indian buead, medlar and manyflower solomonseal rhizome by material preparing, fermenting and other processing steps. The rice wine beverage not only can keep the flavor of rice wine unchanged but also has the effect of tonifying the kidney.

This invention provides a pig feed used for growing and fattening periods, as well as processing method thereof, and relates to the technical filed of pig feeds. The pig feed used for the growing and fattening periods is mainly prepared from the following raw materials: corns, wheat bran, peanut meal, middlings, rice bran, hawthorn fruit wine, pomelo peel, citrus peel, and a functional composition; and the functional composition is a Chinese herbal medicine formula capable of improving immunity, stimulating appetite and promoting healthy growth of the pigs. The invention further provides a processing method of the pig feed. The processing method of the pig feed comprises the following steps: a, preparing a mixed refined feed; b, preparing fruit peel paste; and c, preparing the pig feed. No harmful substances are added into the feed from the formula to the production processes. The prepared feed is capable of providing adequate energy to the pigs in the fattening period; moreover, the feed is capable of promoting food intake of the pigs, enhancing immunity of the pigs, reducing disease rate, and preventing the pigs in the fattening period from blind weight gaining. Thus, the feed is capable of ensuring effective fattening of the pigs in healthy and safe environment, so that the pigs fed with the feed is green and safe in meat qualities and low in feed conversion rate. The processing cycles of the feed are green and environment-friendly, so that the concept of sustainable development is met. The pig feed and the processing method thereof are worthy of promotion.

The invention provides a preparation method and applications of a lamivudine twin drug. Lamivudine, and ursolic acid or oleanolic acid are condensed into the lamivudine-ursolic acid or lamivudine-oleanolic acid twin drug at a low temperature by using ethyl chloroacetate (ethyl bromoacetate) or ethyl chloropropionate (ethyl bromopropionate) as the linking group. The twin drug possibly has a dual-action mechanism; and the twin drug has the action of antivirus, and also has the actions of resisting inflammations, protecting the liver cell membranes, improving the liver function and resisting fibrosis. Thus, the invention organically combines the antivirus therapy and the liver protection treatment and provides a new concept for the research and development of drugs for treating hepatitis.

The invention provides high polymer fabric made of a high polymer material. The fabric is prepared through following preparation processes: A, polyester fibers, bamboo fibers and cuprammonium fibers are subjected to melting granulation, then air-jet texturing filaments are spun and woven, and grey fabric is obtained; B, the grey fabric is put in a finishing liquid for dipping, dried and cooled, and finished fabric product is obtained, wherein the finishing liquidis prepared fromcomponents as follows: 12-20 g / L of titanium dioxide, 18-32 g / L of an acrylate binder, 1-3 g / L of glycerin, 3-4 g / L of a flame retardant, 1-2 g / L of alkyl polyoxyethylene ether succinatesulfonate, 1-2.5 g / L of tribenzylpolyoxyethylenephenol ether, 8-15 g / L of cetyl sodium sulfate and 1.5-3 g / L of an antibacterial agent,the natural antibacterial agent is a plant extract prepared from cudweed,floschrysanthemi, folium artemisiaeargyi, fructusforsythiae andherbahouttuyniae in a mass ratio being (1-2):(1-3):(1-3):(1-2):(1-1.5) through mixed extraction, and density of the plant extract is 1-1.5 g / ml. The pure-natural and non-toxic antibacterial extract is utilized to perform antibacterialtreatment on the fabric, so that the antibacterial effect is realized, the ecological problem in the prior art is solved very well, and energy-saving and environment-friendly effects are realized.
