Potato pulp energy fermentation feed capable of replacing bran and preparation method thereof

Abstract

The invention discloses a potato dregs fermentation energy fodder which can replace bran and a preparation method thereof. The principal raw material of the fodder is potato dregs which is prepared through zymohydrolysis and mixed culture solid-state fermentation by adding accessories of bran, urea, ammonium sulphate, monosodium orthophosphate and bitter salt; the preparation method comprises: preprocessing of material, zymohydrolysis of pectase and cellulase, expanding propagation of strains of production, preparation of liquid seed, mother culture and leaven, fermentation and parching; the invention has the advantages that: the potato dregs fodder prepared through fermentation by adopting the method has the content of crude protein of more than 18 percent, over sized fibres of less than10 percent and ash content of less than 5 percent, the potato dregs fodder can meet the standard of first level wheat bran according to <GB 10368-89 wheat bran for fodder>, has no solanine or other microelements with toxic effects, is rich in multiple Probiotic bacteria and has good flavor, and can be used as energy fodder for fowl and Livestock instead of bran.

Description

technical field [0001] The invention relates to a potato residue energy fermented feed which can replace bran, and also relates to a preparation method of the fermented feed. Background technique [0002] With the continuous development of the feed industry and animal husbandry, energy feed consumption is increasing. Currently, corn and wheat are the main energy feeds, and the market demand is great. Due to the rising trend in the international raw material market in recent years, the price of domestic agricultural products has gradually increased. In the field of livestock and poultry products, this phenomenon is particularly prominent. Corn and bran on the market began to be popular, leading to rising prices of poultry products. [0003] Potato residue is a by-product of the potato starch production process, which contains a large amount of available components such as cellulose and pectin, as well as some starch and a small amount of protein. It can be used as a fermen...

Problems solved by technology

Such as patent application 03134357.0 only adds a small amount of urea and adopts the preparation method of seed koji, although the crude protein content of its dry matter reaches 23.33%, but the crude fiber content is still very high, and its value is 18.67%; Patent application 200510012227.9 squeezes potato residue After dehydration, mix with a certain proportion of auxiliary materials in the form of raw meal, inoculate a certain amount of strains and directly carry out solid-state fermentation to prepare protein feed, but the crude protein content obtained by fermenting potato dregs with this method is only 16.15%
