Abstract

The invention discloses a preparation method of an elytrigia trichophora silage, specifically including the following steps of firstly immersing the elytrigia trichophora with a sodium bicarbonate solution, and then immersing with an acetic acid solution to obtain pretreated elytrigia trichophora; adding compound enzyme into the elytrigia trichophora pre-treated in step 1, and performing enzymatichydrolysis for 3 to 5 hours to obtain an enzymatic hydrolysate; weighing 30 to 50 parts of the enzymatic hydrolysate, 10 to 20 parts of fungi residues, 5 to 10 parts of shell powder, 0.5 to 1 part ofoctyl glucopyranoside, and 0.3 to 0.5 part of anaerobic fermentation preparations; the enzymatic hydrolysate, fungi residues and anaerobic fermentation preparations are mixed uniformly to obtain a mixed raw material, the mixed raw material is fermented under anaerobic conditions for 20 to 30 days, and a fermented material is obtained after the fermentation is completed; the fermented material isuniformly mixed with the shell powder and octyl glucopyranoside to obtain the elytrigia trichophora silage. The preparation method of the invention effectively solves the problem that the elytrigia trichophora has poor mouthfeel and poor nutrition, and the prepared elytrigia trichophora silage has rich nutrition, good palatability, and wide application prospect.

Description

technical field

[0001] The invention belongs to the technical field of silage processing and preparation, and in particular relates to a method for preparing silage silage. Background technique

[0002] In recent years, the rapid development of my country's aquaculture industry has promoted the development of the feed processing industry, which has led to the shortage of protein and energy feed. The use of pasture to replace part of the feed is of great significance to solve the problem of "human and animal competition for food". At the same time, in pasture In the case of limited resources, it is particularly important to actively look for alternative plant feeds other than pasture.

[0003] Henpyrum tomentosa is a common plant with extremely well-developed vegetative bodies. The plant is tall and luxuriant, with 600-800 stems per square meter. When it is mowed twice a year, the highest fresh grass yield per mu can reach 4350kg. However, its crude fiber content is high, the...

Examples

Embodiment 1

[0033] A method for preparing silage of Thinopyrum tomentosa, specifically implemented according to the following steps:

[0034] Step 1: Cut Thinium tomentosa into 1-2cm sections and soak it with a sodium bicarbonate solution with a mass concentration of 5%, take it out and dry it, then soak it with acid solution, take it out after soaking, drain it, and make it dry The water content of the wheatgrass reaches 40%, and the pretreated Thiopyrum tomentosa is obtained;

[0035] Among them, the acid solution is prepared from acetic acid solution with a mass concentration of 5% and sodium lignosulfonate at a mass ratio of 100:3;

[0036] Step 2, adding a compound enzyme equivalent to 0.1% of the weight of the pretreated Thipyrum tomentosa in step 1, enzymatically hydrolyzing at 60° C. for 3 hours to obtain the enzymolyzed material;

[0037] Wherein, the compound enzyme is formed by mixing cellulase and amylase at a mass ratio of 2:1, and the enzyme activities of cellulase and amyl...
