Problems solved by technology

[0003] However, the current silage is prone to mildew and rot locally during the fermentation process, especially the top, bottom and edges are mildewed and rotted, causing a large number of mold and spoilage bacteria to multiply. When the feed is opened, it is easy to form secondary fermentation, and new mold spots or moldy patches will appear on the feeding section. If the situation is not good, it will cause complete mildew and rot, resulting in a lack of feed absorption rate.

Embodiment 1

[0015] The present embodiment provides a kind of method utilizing straw to make silage, comprises the following steps:

[0016] 1) Alkali treatment, shorten the rice straw and corn straw to 1-4 cm, then mix them according to the ratio of 3:2, put them into the sodium hydroxide solution with a concentration of 1.5%, take them out, put them in a container and compact them , take out after 12h;

[0017] 2) acid treatment, the stalks treated with alkali are soaked in 3% hydrochloric acid and then taken out;

[0018] 3) Fermentation with biological bacteria. First, mix the strain base material containing Clostridium butyricum, Bacillus subtilis, Lactobacillus acidophilus, and Lactobacillus cellobiosus with the straw at a ratio of 5:100, and ferment in a sealed container for 4 days, and then mix the base material containing The strain base material of Candida utilis and Pichia pastoris is mixed with the straw according to the ratio of 3:100, and fermented in airtight for 1 day; 7 ...

Abstract

The invention provides a method for manufacturing silage from straw and belongs to the field of animal feed. The method includes the steps of alkali treatment, acid treatment and biological bacterium fermentation. Alkali treatment is conducted on straw, part of cell walls of the straw can be damaged, and the straw is softened; hydrochloric acid treatment is used for neutralizing alkali and damaging part of the cell walls again; then clostridium butyricum, bacillus subtilis, lactobacillus acidophilus and lactobacillus cellobiosas are used for fermentation, and finally candida utilis and pichia pastoris are added for fermentation, so that nutrients of the prepared silage are released more correctly, the feed digestion rate is increased, the silage can improve resistance of livestock, and the diarrhea rate and the death rate of livestock are effectively reduced.

Description

technical field [0001] The invention belongs to the field of animal silage, in particular to a method for making feed from straw. Background technique [0002] With the development of herbivorous livestock industry, high-quality forage grass and fodder crops have become the basis for the development of efficient animal husbandry. Therefore, the development space and prospects of silage will be broader, which is more conducive to the healthy development of animal husbandry. It is an effective way to increase the benefits of herbivorous livestock breeding and product quality, and to improve product competitiveness and unit planting benefits. [0003] However, the current silage is prone to mildew and rot locally during the fermentation process, especially the top, bottom and edges are mildewed and rotted, causing a large number of mold and spoilage bacteria to multiply. When the feed is opened, it is easy to form secondary fermentation, and new mold spots or moldy patches wil...
