Problems solved by technology

[0003] Due to the ammoniated feed promoted in my country in recent years, it not only has high cost and high energy consumption, but also competes with agriculture for fertilizer and pollutes the environment. Some methods have toxic and side effects on livestock
The use of microbial strains to ferment straw feed has the advantages of convenient operation and no pollution to the environment. However, at present, it is necessary to comprehensively solve the problem of inhibiting spoilage bacteria in the process of feed fermentation, preventing secondary fermentation, effectively controlling organic acids and degrading lignocellulose, and reducing costs. There are still issues with ease of use etc.
[0004] CN102132762A discloses a straw feed and its preparation method, the method adopts two-step aerobic and one-step anaerobic fermentation, complicated operation and long fermentation time

Abstract

The invention relates to a preparation method of an activated ferment straw biscuit feed. The method comprises the following steps: pre-treating straws, adding nutritional liquid, fermenting, pressing and forming and the like; the nutritive value of the straws is remarkably improved and the feed can be used as a high-quality feed to feed livestock; so that the feed has the important meanings on the remission of the contradiction between food and feed of people and the livestock, sufficient utilization of renewable resources, reduction of environmental pollution caused by straw incineration, improvement of rural environmental pollution, and promotion of sustainable development of agriculture and animal husbandry; and the feed has good economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of fermented feed, in particular to a preparation method of straw feed, in particular to a preparation method of activated enzyme biscuit feed. Background technique [0002] It is speculated that by 2015, the feed protein gap we need will reach more than 38×104. Opening up new sources of raw materials and improving feed utilization is currently a worldwide research topic. my country is rich in straw resources, with an annual output of 579 million tons. Among them, the straw output of the three major crops of corn, wheat, and rice straw reached 439 million tons, accounting for 75.88% of the total straw output. However, due to the low digestible protein content and high crude fiber content of straw, most of the cellulose cannot be digested and decomposed by the gastrointestinal tract of livestock and poultry, so the nutritional value is low, and most of them are directly returned to the field or burned. Envi...
