Embodiment 1

[0080] With straw / liquid alcohol industrial by-product (moisture content is 70wt%) / DDGS / sprayed corn bran / cotton meal / corn germ meal / corn / premix / salt / calcium oxide / calcium hydrogen phosphate=28 / 12 / 14 / 5 / 6 / 20 / 11 / 2 / 1 / 0.6 / 0.4 dry matter weight ratio (i.e. dry weight ratio) Weigh corn stalks, alkali, liquid alcohol industrial by-products and the above-mentioned auxiliary materials, and perform the following operations to repeat Formulated as a full price compounded ruminant feed:

[0081] 1) Add liquid alcohol industrial by-products (the water content of the final mixture is 8.4wt%) to the corn stalks that are crushed into 1-2cm length in advance, and then place the steam explosion tank (the working pressure range of this equipment is 0.1-3.0 MPa), steam explosion pretreatment at a temperature of 150°C and a pressure of 0.48MPa for 25 minutes, and then all the pretreated materials were sprayed out to obtain steam explosion products;

[0082] 2) adding calcium oxide to the obtaine...

Embodiment 2

[0093] The impact of the different treatments of embodiment 2 on the degradation rate of feed

[0094] Wheat straw is crushed to a length of 1-2 cm, mixed with liquid alcohol industrial by-products (water content 70wt%) at a dry weight ratio of 7:3, and water is added thereto until the water content of the final mixture is 40wt% , followed by steam explosion pretreatment, steam explosion pretreatment at a temperature of 160°C and a pressure of 0.62MPa for 25 minutes, and then all the pretreated materials were sprayed out, and the dry weight ratio of adding and wheat straw was 1:46.67 The calcium oxide was neutralized, and then the feed obtained after drying at 65°C was used as the experimental group. In addition, the feed obtained with the same operations and materials as the experimental group except that no steam explosion pretreatment was carried out was used as the control group 1; the feed obtained with the same operations and materials as the experimental group except fo...

Abstract

The invention discloses a production method of a fiber-containing ruminant feed and a feed produced by the production method, and belongs to the field of processing of ruminant animal feeds. The method comprises the steps of mixing lignocellulose biomass raw materials with liquid alcohol industrial by-products, performing pretreatment, and performing compounding with auxiliary materials so as to prepare the composite functional fiber-containing ruminant feed. According to the production method, the problems that the alcohol industrial by-products cannot be effectively utilized, the treatment cost is high, and the value is low, are solved. The produced feed product is rich in proteins and fibers easy to digest, and a new way is opened up for comprehensive utilization of the alcohol industrial by-products and high-value transformation of lignocellulose.

Description

technical field [0001] The invention relates to the field of ruminant feed processing, in particular to a method for preparing functional fiber-containing ruminant feed by using lignocellulosic raw materials and liquid alcohol industrial by-products and the feed product produced thereby. Background technique [0002] In the ration of ruminants, the proportion of fiber roughage usually accounts for 40wt%-70wt% to stimulate chewing, rumination and rumen peristalsis, which plays an important role in maintaining rumen health and normal growth and development of ruminants. The source of fiber roughage is mainly crop straw, pasture and branches and leaves. Straw feed is one of the important ways to solve the shortage of high-quality pasture in my country, improve the utilization rate of straw, and protect the environment. [0003] The main components of straw are cellulose, hemicellulose and lignin, among which cellulose has a complex crystalline structure, and is combined and cr...
