Modified pear residue chicken feed capable of preventing and treating flu and preparation method of modified pear residue feed

Abstract

The invention discloses modified pear residue chicken feed capable of preventing and treating flu and a preparation method of the modified pear residue feed. According to the method, pear residues are taken as the main raw material and are modified through extraction, soaking, adsorption, drying, mixing and granulation, antinutritional factors such as pectin, tannin and the like in the pear residues are eliminated, cell wall lysis of pear residues is promoted, the degree of polymerization of cellulose is reduced, digestion, absorption and utilization of nutrients in the pear residues by chickens are promoted, the palatability of the pear residues is improved, medicinal functions of the pear residues are increased, the immune function of the chickens is enhanced, occurrence and spreading of the flue can be prevented effectively, the death and culling rate of the chickens is reduced, and the chicken breeding benefit is 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 for preventing and treating influenza 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 ...

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.
