Method for preparing nutritive feed by using corn stalks

Abstract

The invention relates to a method for preparing nutritive feed by using corn stalks. The method comprises the following steps: (1) carrying out centralized collection on harvested stalks, then, crushing the stalks, adjusting the humidity of the crushed stalk powder to 35-38%, and preserving the stalk powder in the shade; (2) loading the stalk powder to gauze bags, then, feeding the gauze bags to cookers, and carrying out pre-boiling for 25 minutes at the temperature of 80-85 DEG C; (3) pouring out the pre-boiled stalk powder, mixing the pre-boiled stalk powder with additives in accordance with that the pre-boiled stalk powder per 100kg is mixed with 2kg of the additives; and detecting the moisture content of the stalk powder after uniform mixing, and controlling the moisture content of the stalk powder to 30-35%; (4) feeding the stalk powder to fermentation tanks, and carrying out anaerobic fermentation for 7-10 days, wherein overturning may not be indispensable during fermentation; (5) taking out the stalk powder subjected to anaerobic fermentation, and carrying out baking treatment in baking equipment with the temperature of 75-80 DEG C so as to enable the moisture content to be lower than 15%; and (6) granulating the stalk powder dried in the step (5), thereby preparing the nutritive feed.

Description

Technical field: [0001] The invention relates to the technical field of feed, in particular to a method for preparing nutritious feed using corn stalks. Background technique: [0002] my country is a large agricultural country with abundant straw resources, and crop straw is an important biological resource that can be transformed and utilized in various forms. However, in recent years, with the transformation of farming methods and lifestyles, the effect of returning crop straw to the field is not ideal, which has led to repeated bans on farmers burning straw. The phenomenon of straw burning is very serious, seriously polluting the environment, directly affecting traffic safety and residents' lives, so it is imperative to ban straw burning. [0003] Crop straw silage has many advantages: less nutritional loss, generally no more than 10%, rich in digestible vitamins, protein, fat and other nutrients, sweet and sour smell, high digestibility, good palatability, can increase ...

AI Technical Summary

Problems solved by technology

Because it cannot be compacted, there is too much air remaining in the straw, which causes aerobic bacteria to multiply and makes the feed moldy and rotten; during the feeding process, air invades the cellar, causing a new round of mildew

The total loss of traditional silage is as high as 30%, and due to the musty smell in the feed, it will seriously affect the feed intake of dairy cows
