In the current pig raising production in China, corn and soybean meal type daily ration is mainly adopted, although the content of crude protein in soybean cakes and soybean meal is high, the soybean cakes and the soybean meal can be supplied by the self by about 30 percent in China, and about 70 percent of demand needs to be imported; on the other hand, mulberry resources in China are very rich, the mulberry planting area reaches tens of millions of acres, the mulberry growth speed is high, the yield is high, and multiple batches of cradles can be cut in one year after the mulberry is planted in the south. The mulberry leaves and stems of the mulberry tree contain higher protein (accounting for more than 20% of dry matter) and have good palatability except that part of leaves are used for silkworm breeding, the mulberry leaves and the stems can be developed to be used as pig protein feed, the digestibility is high, but the growth and the health of the pigs are influenced because the fresh mulberry tree directly feeds the pigs with high water content and is not tolerant to storage and contains anti-nutritional factors, so that the mulberry tree can be used for processing and developing pig protein feed resources by using modern biotechnology and replacing part or all of bean pulp in pig daily feed, grain is saved, the demand of imported bean pulp is reduced, the feed cost is reduced, the planting and breeding combination is realized, the development of the pig industry is promoted, and the income of farmers is increased.

3) the yeast shared by the compound microorganism A and the compound microorganism B is rich in various vitamins, minerals and enzymes, so that the nutritive value of the feed is improved, the fermented flavor is provided, the feed intake of the pork pigs can be increased, and meanwhile, the compound microorganism A and the compound microorganism B have a certain detoxification function, so that the immunity of the pork pigs can be improved, and the quality of pork is improved; the stone powder can release calcium element in pork pig body by reacting with gastric acid and organic acid, and can improve the absorption of calcium element by pork pig; the wheat bran has high content of crude cellulose, contains a large amount of dietary fibers and non-starch polysaccharides capable of adjusting intestinal health, can promote proliferation of probiotics, inhibit field planting of pathogenic bacteria, prevent and treat constipation of pork pigs and improve digestion efficiency; the sucrose can be used as a nutritional additive to improve the growth performance of the pork pigs, not only can prevent hypoglycemia of the pork pigs caused by congenital malnutrition and improve the survival rate of the pork pigs, but also can supplement the sugar in the pork pigs, and in addition, the acid generated in the digestion process of the sucrose can adjust the pH value of the contents in the gastrointestinal tract, thereby promoting the digestion of the pork pigs;
(3) as can be seen by comparing the embodiment 4 with the comparative examples 4-6, the feed for pigs selects and plants the whole mulberry fermentation plant as the protein feed resource to replace all or part of the raw materials such as soybean meal in the feed for pigs, has obvious effect on the weight gain effect of pork pigs, can be combined with breeding and breeding by adopting the mulberry protein feed, has the weight gain effect, improves the quality of pork, realizes ecological cycle agriculture, can also fully utilize local resources to plant mulberry, solves the problem of shortage of the protein feed raw materials, and can also effectively solve the contradiction of the current domestic pig breeding and dislocation.
The above description should not be taken as limiting the invention to the embodiments, but rather, as will be apparent to those skilled in the art to which the invention pertains, numerous simplifications or substitutions may be made without departing from the spirit of the invention, which shall be deemed to fall within the scope of the invention as defined by the claims appended hereto.
