Modified pear residue feed additive for promoting animal fattening and preparation method thereof

Abstract

The present invention discloses a modified pear residue feed additive and a preparation method thereof for promoting animal fattening. The preparation method uses pear residues as raw materials, and includes the following processing steps: medicinal material extracting, residue burning, medicinal material ash soaking, air-drying and grinding, decoction adsorbing, seasoning and coating, and drying and packaging. The preparation method eliminates pectin, tannin and other anti-nutritional factors of the pear residues, promotes cell wall lysis of the pear residues, reduces the cellulose polymerization degree, promotes digestion, absorption and utilization of nutrients in the pear residues for animals, improves the appetite and food intake of the animals, accelerates the growth and development process of the animals, reduces the feed consumption of the animals, and improves animal breeding efficiency.

Description

technical field [0001] The invention relates to the technical field of animal feed processing and preparation, in particular to a modified pear residue feed additive for promoting animal fattening 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 hemice...

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.
