No. Institute of Microbiology, Chinese Academy of Sciences, postal code: 100101), the preservation number is CGMCC NO.15419, and the preservation date is March 7, 2018. The present invention also provides a preparation method of live Pediococcus lactis preparation, specifically comprising: using Pediococcus lactis as a fermentation strain, adopting an optimized fermentation process and a fermentation medium, and putting it into a tank after primary, secondary, and tertiary cultivation , centrifuge to obtain active bacteria slime, add stabilizer and protective agent, then granulate through a granulator, and then add a coating solution in a coating machine for coating, and finally obtain a viable Pediococcus lactis preparation. The Pediococcus lactis HEW‑AP27 of the present invention is acid-resistant, bile-salt-resistant, high-temperature-resistant, has strong acid-producing performance, and can also inhibit the growth and reproduction of pathogenic bacteria.

The invention provides a sow aphrodisiac material, which is characterized by comprising the following components in part by weight: 0.5 to 1.5 parts of pearl barley, 0.5 to 1.5 parts of epimedium herb, 0.5 to 1.5 parts of herba lycopi, 0.5 to 1.5 parts of tuber fleeceflower stem, 0.5 to 1.5 parts of officinal magnolia bark, 0.5 to 1.5 parts of cassia bark, 0.5 to 1.5 parts of tangerine peel, 0.5 to 1.5 parts of cyrtomium rhizome, 0.5 to 1.5 parts of indigowoad leaf, 0.5 to 1.5 parts of perilla stem and 0.5 to 1.0 part of adhesive. The sow aphrodisiac material has the advantages of meeting thenormal physiological requirements, guaranteeing that replacement gilts and multiparous sows can successfully enter the next reproductive cycle, improving the production performance of the sows, meeting the requirements of large-scale swine production, implementing an idea that prevention is more important than treatment, reducing medicament cost and integrally improving benefit of swine production.

The invention relates to an ecological breeding method for a pig, in particular to an ecological breeding method for a hybrid pig. The method comprises the steps of utilizing an excellent local variety and a foreign variety to conduct hybrid so as to obtain a hybrid generation, and feeding a hybrid piglet, wherein piglet creep feed which can reduce the diarrhea rate is used, high-cost raw materials of plasma protein powder, fish meal, whey powder, maize and the like are not added into the creep feed, thus the feed cost is reduced, new fodder of vinegar residue, alkaloid, yellow mealworm powder, sesame-seed cake dregs, coconut cake dregs, sunflower cake dregs and the like are firstly added into the creep feed, non-drug control of diarrhea is achieved, the disadvantages of an existing creep feed is overcome, the immunity of the piglet is improved, the food consumption and the growth rate of the piglet are increased, the diarrhea rate of the piglet is reduced, the stress-reaction of the weaned piglet is reduced, growth retardation is avoided, the palatability is good, and the pig meat is healthier and safer. Meanwhile, equipment and method that can guarantee heat retaining of the piglet is provided, a waste gas treatment method can make the gas fully recycled and utilized, heat supplying of the pig house is achieved, and the environment inside the pig house is improved at the same time.

The invention belongs to the technical field of feed additives, and in particular relates to a Chinese herbal medicine superfine powder feed additive for producing high-quality pork. The additive is prepared from the following Chinese herbal medicines in parts by weight: 3 parts of astragalus root, 3 parts of hairy asiabell root, 3 parts of hawthorn, 3 parts of medicated leaven, 2 parts of dried orange peel, 2 parts of fennel, 2 parts of wild chrysanthemum, 2 parts of cinnamon, 1 part of pine needle, 1 part of liquorice, 2 parts of fleece-flower root and 3 parts of bighead atractylodes rhizome. All the raw materials are weighed according to the prescription proportion; after being mixed, the raw materials are made into superfine powder of 200 meshes; and the use adding amount is 0.75 percent of the total weight of the feed. In the invention, the reasonable compatible Chinese herbal medicines are prepared into the superfine powder, the advantages of the Chinese herbal medicine prescription and superfine powder are fully exerted to achieve the effect of improving pork quality, the pork has the advantages of reduced acidity, bright color, increased marble textures, reduced water lossrate and drip loss, improved tenderness, thinned muscle fibers, obviously increased saturation degree of back fat, and obviously improved muscle saturated fatty acid content and essential fatty acid content, and considerable economic benefits are achieved.

The invention aims to provide a method for improving meat percentage of pigs by establishing a protein precipitation curve equation. The method has the beneficial effects of improving the meat percentage of pigs, simultaneously improving the nutrient content of the pigs and lowering the production cost of pig raising by scientifically guiding the production mode of pigs by utilizing a scientific mathematical model. In order to achieve the effects: the method is characterized by utilizing Gompertz equations to fit growth curves of weights of castrated boars and sows, fatless lean meat amount and day of age, utilizing a derivation equation of the Gompertz equation of fatless lean meat amount and day of age to establish an equation of daily gain of fatless lean meat and day of age, utilizingthe derivative equations of the Gompertz equation of weights and day of age and the Gompertz equation of daily gain of fatless lean meat and day of age to establish a potential finishing pig protein precipitation model of weights and daily gain of fatless lean meat, computing the date with peak fatless lean meat amount and the date with peak protein precipitation of the pigs according to the actual food intake of the pigs and slaughtering the pigs according to the actual production requirements.

The invention relates to feed set meals for pigs in different physiological stages, and discloses a systematic nutrition scheme for sows to increase the number of market commercial pigs each year, and the benefits of pig farms are improved accordingly. The systematic nutrition scheme comprises a sow fecundity N+ series product, a piglet higher survival rate 7030 scheme, a pig growing and fattening more-profit making V+ series product and matched feeding patterns. According to the sow fecundity N+ series product, healthy reproduction of boars can be guaranteed by providing enough maintenance, growth, reproduction and immunization nutrition. According to the piglet higher survival rate 7030 scheme, the nutritional requirements of pig stocks in each production stage are met by taking a 'comprehensive nutrients + high and balance nutritional levels + high-quality nutrient sources ' scheme into account, the digestive absorption capacity and the intestinal immunity of the pig stocks are improved by guaranteeing the gastrointestinal tract health, and the self immunity of the pig stocks is reinforced by guaranteeing production nutrition and paying close attention to immune nutrition and stress nutrition. The pig growing and fattening more-profit making V+ series product is prepared according to different nutritional requirements of the pigs in different growth and development stages, and the obtained commercial pigs grow fast, low in feed ration and good in meat quality.
