Activated enzyme straw feed and preparation method thereof

Abstract

The invention relates to an activated enzyme straw feed and a preparation method thereof. According to the feed, composite strains are optimized and combined by microbial fermentation technology, and a variety of crop straws and other agricultural and sideline products are fermented to produce pellet feed. In the invention, the crop straws are fully utilized, the quality of the feed is perfected by the fermentation of mixed microbial fermentation bacteria to greatly improve the nutritive value and utilization rate of the raw materials, and the palatability of the straw feed is perfected by fermentation to improve the feed intake and daily gain of livestock.

Description

technical field [0001] The invention belongs to the technical field of fermented feed, and in particular relates to a straw feed and a preparation method thereof, in particular to an activated enzyme straw feed and a preparation method thereof. Background technique [0002] 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. At present, with the rapid development of animal husbandry, the dependence of animal husbandry on grain has been intensified, but the amount of straw used as feed is small, and even if it is used as feed, the utilization rate of straw and the rate of feed return are low due to improper processing and utilization. Crop straw has low nutritional value, poor palatability and low digestibility. If it is properly processed and adjusted, it can be used to feed livestock. ...

AI Technical Summary

Problems solved by technology

[0004] (1) Only using physical treatment methods, such as simple physical treatment of straw or shortening or crushing of straw, cannot cause major changes and improvements in the nutritional content of straw;

[0005] (2) Only chemical methods are used, such as using salt, plaster of paris, urea, salt, sugar, potassium permanganate, formic acid, etc. to do simple chemical treatment on the straw, which does not change much the nutritional content of the straw, and there is still some Side effects, and cause certain pollution to the environment;

[0006] (3) By adding complex trace elements and enzyme preparations, its production cost is relatively high, which is not convenient for popularization and application in rural areas;

[0007] (4) Using edible fungi to decompose and transform the straw, the cycle of its decomposition and transformation is relatively long, generally takes more than one month, and the production efficiency is low;

[0008] (5) Use microorganisms to decompose compound bacterial powder and ferment straw to produce feed, but specialized factories are required for the special production of compound bacterial powder, which is not convenient for widespread application in rural areas

[0009] Due to the ammoniated feed promoted in our 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, and 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.
