Method for preparing biological feed from rice straw

Abstract

The invention belongs to the field of deep processing of crop straw, and relates to a manufacturing technique of a biological feed, particularly a method for preparing a biological feed from rice straw, more particularly a low-cost high-nutrient aromatic-flavor good-palatability nutrient straw biological feed which is prepared by fermenting rice straw as a main raw material and rice bran and corn flour as auxiliary materials with multistage expanded effective microorganisms (EM). The biological feed has the advantages of wide raw material sources, low price, simple preparation technique, and high content of beneficial microorganisms; the active substances secreted by the beneficial microorganisms can promote the animal organism to obviously enhance the immunity, thereby reducing or avoiding the use of veterinary medicines; and thus, the invention can be used for producing high-quality stock raising products. The biological feed prepared by the method has the advantages of low cost, wide functions and favorable effect, can enhance the feed conversion ratio, reduces the consumption of concentrated feed, and lowers the cultivation cost.

Description

technical field [0001] The invention relates to a production technology of biological feed, belongs to the field of deep processing of crop straws, and in particular relates to a method for preparing biological feed from rice straws. Background technique [0002] In the breeding industry, feed accounts for about 70% of the entire feeding cost; at present, most of the feed products circulating on the market contain high energy and protein, which requires expensive grain and protein feed, so that the cost of feed is at the top of the list. If it is not high enough, the cost of breeding will be higher, and the economic benefits of the breeding industry will be low, which is also the main factor affecting the economic benefits of the breeding industry. How to reduce the feed cost of the aquaculture industry is a difficult problem in the development of the aquaculture industry. Only by solving this problem can the aquaculture industry develop further. [0003] In the past, it wa...

Problems solved by technology

[0008] Although the straw contains a certain amount of nutrition, it has a large molecular weight and a firm composition. If it is directly fed to livestock and poultry without scientific treatment, it is not easy to be digested by livestock and poultry. Therefore, the direct use of straw as feed is of low value.
