**Straw Biological Feed Production Technology Project**
![]()
**I. Overview**
In countries like the United States, Japan, and Canada, the use of straw and forage as animal feed has long been a well-established practice. Even in developed nations, the cost of meat, poultry, and eggs is nearly as low as in China. However, recent years have seen challenges with many straw fermentation products from research institutions and manufacturers. For example:
(1) The fermentation process often takes too long, and the results are not as effective as those achieved within 15–30 days. For instance, EM liquid is not suitable for fermenting straw.
(2) The quantity required is large, leading to high costs. Some market products require up to 500 kg of starter per 500 g, with retail prices ranging from 20–30 RMB. This makes it difficult for farmers to adopt and scale up the technology.
**II. Principles and Functions**
The company utilizes microbial strains from the Chinese Academy of Sciences and combines Japanese expansion techniques with traditional Chinese propagation methods. After four years of development, the bio-straw fermentation agent was tested by the Ministry of Agriculture in 2002 and met all quality standards. It is now considered one of the most advanced in the country.
The fermentation starter works through several key mechanisms:
First, highly efficient decomposition factors break down crude fiber, lignin, and long molecular chains in straw into easily digestible carbohydrates that livestock can absorb. Second, beneficial bacteria convert hard-to-digest organic and inorganic nitrogen into nutrient-rich bacterial protein. Third, during fermentation, the product generates proteases, lipases, amylases, cellulolytic enzymes, and B vitamins, which are unmatched by conventional feeds. Finally, these beneficial microorganisms help improve gut health, boost immunity, and reduce disease incidence in animals.
**III. Prospects for Bio-Straw Feed**
China produces over 900 million tons of straw annually, yet less than 10% is used as feed. The rest is often burned or returned to fields, causing environmental damage. The central government has recognized the importance of straw utilization, and last year, Premier Zhu Rongji allocated 10 million yuan for related research. With growing awareness among local governments and farmers, the market for bio-straw feed is expanding rapidly. The product has already established over 60 sales outlets nationwide, but there's still massive room for growth.
**IV. Investment and Production Efficiency**
Using bio-straw starters, the production process is simple and cost-effective. Key equipment includes crushers, fermentation tanks (plastic-free woven bags, cylinders, or cement pools), dryers, and packaging machines. A monthly investment of about 10,000 RMB can produce 30 tons of biological feed. The factory area needs only 200 square meters, and power can be provided through two- or three-phase electricity. No pollution occurs, and only 3–5 workers are needed. Raw materials are widely available, making the production cost low and profits high.
**Key Features of the Picking Brand Biostraw Fermenting Agent:**
1. It can ferment various plant straws, such as rice, wheat, corn, and legumes, as well as chicken manure, cow dung, and grass powder, into high-quality feed. Crude fiber is reduced by about 45%, and the feed is rich in bacterial protein, digestive enzymes, and essential vitamins.
2. Low cost: 500–1000 kg of dry material can be fermented using just 500 grams of starter. The unit cost is 1/5 to 1/6 of other products, around 3 cents per kilogram.
3. Simple process: Fermentation takes only 3–7 days, regardless of season. No need for sealing, and the finished product can be stored for long periods in a wet state.
4. The fermented feed has a pleasant aroma and flavor, making it highly palatable to livestock. It can replace 30–50% of concentrate feed, improving growth rates and reducing costs.
**Summary**
Leveraging technology from the Chinese Academy of Sciences and approved by the Ministry of Agriculture, this bio-straw fermentation agent is promoted by Beijing Shennong Caijing Biotechnology Co., Ltd. It can quickly turn various agricultural waste—such as crop straw, weeds, soy sauce residue, bean cake, and more—into green, eco-friendly feed. One ton of finished feed requires just 1 jin (about 500 grams) of starter, and the process takes 3–7 days. This allows rural communities to produce feed locally, reducing transportation costs and turning waste into valuable resources.
