Chicken feed containing modified pear residues and capable of improving disease resistance and preparation method of chicken feed

Abstract

The invention discloses chicken feed containing modified pear residues and capable of improving disease resistance and a preparation method of the chicken feed. According to the method, the pear residues are taken as main raw materials and modified through extraction, soaking, adsorption, drying, mixing and granulation, anti-nutritional factors such as pectin, tannin and the like in the pear residues are eliminated, pyrolysis of cell walls in the pear residues is promoted, the polymerization degree of cellulose is reduced, chickens can digest, absorb and utilize nutrients in the pear residues better, the palatability of the pear residues is improved, the medicinal function of the pear residues is increased, the immunity of the chickens is improved, occurrence and spreading of dysentery and flu are prevented, the death and culling rate of the chickens is reduced, and the chicken breeding benefits are increased.

Description

technical field [0001] The invention relates to the technical field of animal feed processing and preparation, in particular to a modified pear residue chicken feed with improved disease resistance and a preparation method thereof. Background technique [0002] Pear pomace is the residue of fresh pears after crushing, squeezing and extracting juice. It is mainly composed of peel, core and residual pulp. It contains rich nutrients such as soluble sugar, vitamins, minerals and cellulose. It is a good feed resource. Hang or dry to make it light yellow in color and fragrant. It has been determined that in the pear pomace, the peel and pulp account for 96.2%, the fruit seeds account for 3.1%, and the fruit stems account for 0.7%. The nitrogen-free extract of pear pomace is 61.5%, of which the total sugar is 15.1%, the crude fat is 6.8%, and the crude protein content 6.2%. In addition to a small amount of husk and fruit stem in the crude fiber, the pulp and peel are mostly hemic...

Problems solved by technology

Due to technical limitations, my country's pear residue resources have only been processed for a long time. This low-level processing makes the added value of pear residue processing and production low, and the industrial chain is short, which hinders the progress of my country's modern industry.
