Method for making corn straw feed

Abstract

The invention discloses a method for making a corn straw feed. The method comprises the steps of first naturally air-drying or drying just harvested corn straws; fibrillating the corn straws by using a breaking machine while the water content is 27-35% so as to obtain straw filaments which are 100 m long and 4mm wide; and then adding urea which accounts for 5% of the weight of the straw filaments and hydrated lime which accounts for 4% of the weight of the straw filaments to the straw filaments; filling to a compression tank after uniformly mixing; compressing by using a press to obtain material blocks with a concentration of 160 kg/m<3>; and placing for not less than three days in a natural state to obtain the corn straw feed. The corn straw feed disclosed by the invention has the advantages of wide raw material source, low cost, and convenience for scale production, storage and transportation; in the feed, a fiber content is obviously reduced and a crude protein content is increased; and by using the invention, difficulties of insufficient grass and overgrazing in pasturing areas are solved, and a way is found for large quantities of corn straws in rural areas.

Description

Technical field: [0001] The invention relates to feed, which is a method for preparing corn stalk feed by processing corn stalks into feed for herbivores such as cattle and sheep, which can not only increase the protein content and digestion utilization rate, but also facilitate large-scale production and reduce costs. Background technique: [0002] At present, in order to improve the digestion and utilization rate of corn stalks by herbivores, the commonly used corn stalk feed production methods include physical or chemical methods, etc. Pure physical treatment can only weaken the mechanical strength of the straw, and the cellulose and crude protein content in its chemical composition No change; when treated with chemical methods such as alkalization and ammoniation and treated with microbial methods such as silage and micro-storage, due to the influence of its own characteristics, the treatment time is long, the volume is large, the transportation is inconvenient, and it is...

[0002] At present, in order to improve the digestion and utilization rate of corn stalks by herbivores, the commonly used corn stalk feed production methods include physical or chemical methods, etc. Pure physical treatment can only weaken the mechanical strength of the straw, and the cellulose and crude protein content in its chemical composition No change; when treated with chemical methods such as alkalization and ammoniation and treated with microbial methods such as silage and micro-storage, due to the influence of its own characteristics, the treatment time is long, the volume is large, the transportation is inconvenient, and it is not suitable for large-scale production; in recent years Although the emerging granulation treatment method can theoretically be produced on a large scale and commercially, it is difficult to popularize due to the high production cost and the small processing amount per unit time.

In addition, it takes a short time for the water in the straw to drop from 90% to 40%. As the appearance of the straw hardens and the straw is thick, it will take a long time for the water to drop from 40% to about 10%, which often delays the farming time. When the moisture content of the straw is about 30%, it is often burned, which wastes resources and pollutes the environment
