Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the amount of existing straw used as feed is small, and most of the straw is burned on the spot, which pollutes the air and wastes data. It provides a microbial straw starter that can fully ferment straw and use it as feed. The method of using it to produce straw feed

Embodiment 1

[0044] Example 1: Weigh 20g of yeast, 25g of Trichoderma, 25g of Bacillus cereus and 30g of Lactobacillus bifidus and mix them evenly to prepare materials respectively, and adopt the following steps to carry out microbial fermentation to obtain straw feed: ① Straw preparation: the straw is dried before use Dry, remove the sundries and moldy and rotten ones; ②Cut short: Use a shredder to cut the straw prepared in step ① to 5 cm; ③Mix and inoculate: use 5 grams of microbial straw starter for each ton of dry straw, Put the weighed microbial straw starter into 100ml nutrient solution to activate for 6 hours, add water to adjust the pH to 7.2 for later use; add water to the straw, the weight ratio of water to straw is straw:water=1:0.8, after adding water Spread the straw on the cement pond or on the ground, sprinkle the activated microbial straw starter once every 35 cm thick straw, after layer upon layer compaction, cover with plastic film, seal tightly around, compact and seal; ④...

Embodiment 2

[0045] Embodiment 2: Weigh 18g of yeast, 27g of Trichoderma, 23g of Bacillus cereus and 32g of Lactobacillus bifidus and mix them evenly to prepare materials respectively, and adopt the following steps to carry out microbial fermentation to obtain straw feed: 1. Straw preparation: use green straw, Eliminate the sundries and moldy and rotten ones; ②cut short: use a shredder to cut the straw prepared in step ① to 4 cm; ③mix and inoculate: use 2 grams of microbial straw starter for each ton of green straw, and weigh Put a good microbial straw starter into 100ml nutrient solution to activate for 6 hours, add water to adjust the PH to 7.2 for later use; add water to the straw, the weight ratio of the amount of water added to the straw is straw:water=1:0.6, the straw paving after adding water In the cement pool or on the ground, sprinkle the activated microbial straw starter for every 40 cm thick straw, after layer upon layer compaction, cover the top with plastic film, seal tightly ...

Embodiment 3

[0046] Example 3: Weigh 22g of yeast, 23g of Trichoderma, 27g of Bacillus cereus and 28g of Lactobacillus bifidus and mix them evenly to prepare materials, and adopt the following steps to carry out microbial fermentation to obtain straw feed: ① Straw preparation: drying the straw before use Dry, remove the sundries and moldy and rotten ones; ②Short: Use a shredder to cut the straw prepared in step ① to 3 cm; ③Mix and inoculate: use 6 grams of microbial straw starter for each ton of dry straw, Put the weighed microbial straw starter into 100ml nutrient solution to activate for 4 hours, add water to adjust the pH to 7.2 for later use; add water to the straw, the weight ratio of water to straw is straw:water=1:1, after adding water Spread the straw on the cement pond or on the ground, sprinkle the activated microbial straw starter once every 40 cm thick straw is laid, after layer upon layer compaction, cover with plastic film, seal tightly around, compact and seal; ④Fermentation:...

Abstract

The invention discloses a microbial straw fermentation agent and a method for producing a straw forage by utilizing the fermentation agent, and concretely relates to a microbial straw fermentation agent used for fully fermenting straw for forming a forage and a method for producing a straw forage by utilizing the fermentation agent. The to-be-solved technical problem is that the current quantity of straw used as a forage is relatively small, majority of straw is burned on site, air is polluted and resource is waste. The microbial straw fermentation agent comprises an anaerobic bacteria fermentation agent and an anaerobic bacteria fermentation agent, wherein the anaerobic bacteria fermentation agent is microzyme, trichoderma spp and bacillus cereus, and the anaerobic bacteria fermentation agent is lactobacillus bifidus. By employing the technical scheme, the microbial straw fermentation agent improves the palatability of a fermented straw forage, substantially reduces the crude fiber content of the straw forge, improves the digestion absorption rate of ruminants, and reduces stomach and intestine disease incidence of animals. Working intensity of workers is mitigated, fermentation cost is reduced, and digestion rate is improved.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to a microbial straw starter and a method for producing straw feed using the same. Background technique [0002] According to statistics, the world's annual straw production is about 2-3 billion tons, and my country's is about 600 million tons. Most of the straw is burned on the spot, which not only pollutes the air environment, causes haze weather, but also causes waste of data. If 60%-65% of the straw is used as feed, it can meet 80% of the roughage requirements of cattle, sheep, horses, etc. in my country. [0003] At present, the amount of straw used as feed is small, the main reasons are: [0004] ① Low nutritional value, mainly due to low protein content; ② Low digestibility, the main reason is: high wood content, lignin and cellulose combine to form a dense mosaic structure, forming a protective layer on the surface of available nutrients, limiting digestion of internal nutri...
