Woody plant feed additive for livestock and poultry, and preparation method of feed additive

Abstract

The invention discloses a woody plant feed additive for livestock and poultry, and a preparation method. The feed additive comprises the following raw materials in parts by weight: 30-60 parts of seabuckthorn branches, 5-15 parts of gingko leaves, 5-15 parts of lycium barbarum branches, 5-12 parts of alfalfa, 10-20 parts of tea residue and 5-15 parts of pine needles. The raw materials are proportioned and mixed in parts by weight, and subjected to fine grinding to form ultrafine powder with the particle size of 1-50 micrometers, and basal feed and the feed additive are mixed according to the weight part ratio of 100:(1-20) and then used for feeding. The feed additive can improve the palatability of the basal feed, improve the gastrointestinal function and immunity as well as fur and feather brightness of fed animals, promote absorption of the basal feed, and improve the ratio of feed to meat or reduce cycle of slaughter.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to woody plant feed additives and a preparation method thereof. Background technique [0002] There are nearly a thousand kinds of renewable agricultural and forestry waste resources such as rice husks, straws, tea dregs, fruit tree branches, pine and mulberry needles and other woody or woody plants in my country, and the annual agricultural and forestry wastes total more than 1 billion tons. The output is huge, and its nutritional value is rich, containing effective components such as multivitamins, amino acids, proteins, fats, minerals, etc. that livestock and poultry feed needs. For example, the protein contained in branches and leaves of locust tree, elm tree, pine tree, milky way and many fruit trees accounts for more than 25% of dry matter, which can be completely used as protein supplement for animals. For another example, pine needles contain 11 kinds of amino acids needed for ...

AI Technical Summary

Problems solved by technology

[0004] Most of the proteins, fats and sugars contained in woody plants exist in macromolecular structures such as crude protein, crude fat and cellulose, while components such as amino acids and vitamins are mostly wrapped in tough cell walls Generally, it can only be digested and absorbed by animals by hydrolyzing large molecules into small molecules through cooking or fermentation, and releasing the active ingredients in the cells by breaking the wall. High cost has become an obstacle to popularization and promotion.
