Method of preparing cotton-stalk feed

Abstract

The invention discloses a method of preparing cotton-stalk feed, which comprises the following steps: the cotton-stalk core is taken as a raw material, and air separation, edulcoration, softening, stacking, loading, ammoniation are carried out on the raw material in sequence to obtain the cotton-stalk feed. The invention has the advantages of simple and convenient preparation method, low cost, needs no large-scale equipment, and is environment-friendly and safe. Moreover, the invention can make full use of existing cotton-stalk raw materials, and the prepared cotton-stalk feed has the advantages of high nutritive value, fine palatability, high digestibility, no toxicity and pollution and the like.

Description

technical field [0001] The invention relates to a method for producing animal feed, in particular to a method for producing feed from crop stalks. Background technique [0002] The main components of crop stalks are cellulose, hemicellulose, lignin and polyvalan. Cellulose, hemicellulose, and lignin are bound together by various chain bonds, and have a high degree of crystallinity and polymerization, presenting a stable chemical structure. The processing of crop straw feed is to use chemical or biological methods to weaken and destroy the compact structure between cellulose, hemicellulose and lignin, and decompose it into various nutrients that can be absorbed by livestock, while creating a feed that is suitable for livestock. The micro-alkaline environment of rumen microbial activity further improves the nutritional value and digestibility of straw feed. [0003] Cotton is a semi-woody plant, and its stalk refers to the cotton stalk with branches, leaves, roots and bolls ...

AI Technical Summary

Problems solved by technology

However, in the current production of cotton stalk feed, cotton stalks are generally directly crushed as raw materials for feed production, but due to the existence of bast fibers in the cotton stalk bark, it is very difficult to cut and crush cotton stalks; Cotton stalks after cotton roots, cotton seeds and cotton leaves (all of which contain toxic components - gossypol) also contain a certain amount of gossypol in the cotton stalk bark, which will also bring in the raw materials for feed production. toxic ingredients

In addition, the bast fiber, wax and silicon contained in the bark of cotton stalks reduce and limit the digestibility of cotton stalks; as a semi-woody plant, cotton stalks have a high degree of lignification, and the straw feed prepared from cotton stalks is rough and hard. , poor palatability, difficult processing

[0005] The Chinese patent No. ZL200720062277.2 titled "Cotton Stalk Skin-Core Separator" has successfully realized the mechanized separation of cotton stalk skin and cotton stalk core. One machine can separate 300kg of cotton stalk per hour, which is the mechanization and production of cotton stalk feed. Industrialized production has created conditions, but so far, there has not been any report on the separation of cotton stalk skin and core by mechanized methods, and the use of cotton stalk core as raw material to produce animal feed
