Fattening pig feed

Abstract

The invention discloses a fattening pig feed. The fattening pig feed consists of fresh sweet potato peel or sweet potato residues, an adsorbent, cakes, urea, ammonium sulfate, calcium hydrogen phosphate, magnesium sulfate, aspergillus oryzae, aspergillus niger, saccharomyces cerevisiae, candida, lactic acid bacteria and the like. The aspergillus niger, saccharomyces cerevisiae and aspergillus oryzae which are rich in various enzyme systems are used for aerobic fermentation, high molecular substances such as pectin, crude fibers, proteins, starch and the like in fermentation materials are rapidly degraded, and an inorganic nitrogen source is converted into thallus protein. Lactic acid and other active nutrient substances are generated by the lactic acid bacteria by utilizing small molecularnutrient substances. The fattening pig feed is a novel resource utilization type biological feed and has a growth promoting effect on fattening pigs.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to a feed for fattening pigs. Background technique [0002] Sweet potatoes, also known as sweet potatoes, sweet potatoes, sweet potatoes, etc., are rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. They have the effects of anti-cancer, heart protection, emphysema and diabetes prevention, and weight loss. The reputation of "longevity food". Sweet potato dregs is a by-product of sweet potato starch production process, rich in nutrients, studies have shown that fresh sweet potato dregs contain 90.96% water, 3-5% starch, 1.51% cellulose, 0.11-0.28% ash, and 0.26-0.95% protein. [0003] The processing of dried sweet potatoes produces a large number of by-products, sweet potato skins, and sweet potato flour residues produced by processing sweet potato flour. They are good feed for raising livestock, but if they are not dried in time, they are...

AI Technical Summary

Problems solved by technology

[0003] The processing of dried sweet potatoes produces a large number of by-products, sweet potato skins, and sweet potato flour residues produced by processing sweet potato flour. They are good feed for raising livestock, but if they are not dried in time, they are easy to become rancid and pollute the environment. Most sweet potato processing is in winter, and winter Sweet potato skin and sweet potato powder dregs are difficult to dry

Even after a long time of drying, it is labor-intensive and time-consuming, and its nutritional loss is relatively large, and the protein, calcium and phosphorus content of sweet potato skin and sweet potato powder are very small, and the protein contained in the dry matter of sweet potato skin and sweet potato powder is about 4%, and sweet potato skin and sweet potato powder slag contain pectin (pectin accounts for about 20% of the dry matter of sweet potato skin) and other non-digestible substances are higher, which can easily cause diarrhea in livestock and poultry, indigestion, symptoms such as loss of appetite, so Directly added as feed, the amount added is small, and the economic benefit is not obvious
