Straw biological feed leavening agent, straw biological feed and production method thereof

Abstract

The invention discloses a straw biological feed leavening agent which comprises compound enzyme, probiotics and a special additive. The special additive can promote the activity of the enzyme and rapid propagation of the probiotics, so that the problem of sugar feedback inhibition in a straw degrading process is well solved; the nutrition of straws can be converted into bacteria active proteins and glucose type high-nutrition substances to the maximum extent. On the basis of the straw biological feed leavening agent, the invention provides a biological feed which is short in leavening time, large in raw material supply range and low in cost and a production method for the biological feed.

Description

technical field [0001] The invention relates to the technical field of biological feed, in particular to a straw biological fermentation agent, a straw biological feed and a production method thereof. Background technique [0002] Our country has a lot of people and little land, and the per capita food is not much. Every year, more than 50 million tons of grains such as beans and corn are imported. With the development of society and the improvement of people's living standards, people pay more and more attention to the flavor and safety of food. The demand for meat, egg and milk is increasing. my country produces about 500 million tons of grain every year, most of which become feed grain. my country produces about 700 million tons of crop straw every year. Except for a small amount of fuel and roughage for ruminants, a considerable part is burned, which not only pollutes the environment, It also wastes resources in vain. Over the years, many technicians have done a lot of ...

Problems solved by technology

my country produces about 500 million tons of grain every year, most of which become feed grain. my country produces about 700 million tons of crop straw every year. Except for a small amount of fuel and roughage for ruminants, a considerable part is burned, which not only pollutes the environment, It's a waste of resources

Over the years, many technicians have done a lot of effective work in using straw instead of grain to raise livestock and poultry, and have applied for thousands of patents, making the work of saving grain a reality. Inventions based on the utilization rate of digestion and utilization, and the inventions and creations of using straw and other roughages to feed monogastric animals such as pigs and chickens after being processed by bio-fermentation technology are still rare, although there are some inventions that can use waste resources to ferment and use them as feed for pigs and chickens , but due to the constraints of quality, addition amount, cost, effect and other factors, the scope of promotion is not large

For example, No. 90105689.8 patent discloses the method of utilizing straw to produce protein feed. It utilizes sugar residue, starch residue, etc. to inoculate and ferment. The method of producing protein feed with plant stalks uses edible fungus strains to ferment. The disadvantage is that the bacteriostasis time and fermentation time are long, and it is also difficult to promote on a large scale; such as patented technology No. 200310107070.9. Probiotics are used, the expression effect is good, but the fermentation time is as long as 10 days, and it can only replace 10-30% of the mixed feed; another example is the patent No. 01102202.7, the quality of the protein feed produced by it is very good, but the amount of starter used It takes more than 10‰, and the fermentation time is 7 days, and the production cost is relatively high, and it takes a long time in the fermentation workshop, so it is difficult to promote in a large scale.
