Agricultural wastes such as straw and sugarcane leaves are transformed into feed through fermentation, and the market prospect is broad

With people's attention to environmental protection and sustainable development, the treatment and utilization of agricultural waste has become a topic of great concern. Agricultural wastes such as straw and sugarcane leaves, as rich resources, can be made into high-quality feed after fermentation, which has brought broad development prospects to the feed market.

First of all, the fermentation of agricultural waste can transform it into high-quality feed raw materials. The traditional way of disposing of agricultural waste is often incineration or landfill, which not only wastes resources, but also causes serious pollution to the environment. Through fermentation, agricultural waste can be converted into nutrient-rich feed to meet the growth needs of livestock and poultry. This can not only improve the quality of feed, but also reduce the demand for traditional feed raw materials, reduce the cost of feed production, and bring huge economic benefits to the aquaculture industry.

Secondly, the feed after the fermentation and treatment of agricultural waste has good environmental performance. With the continuous expansion of livestock and poultry breeding, the raw materials required for traditional feed production are also increasing, resulting in overexploitation of farmland resources and environmental pollution. The feed after fermentation and treatment of agricultural waste can not only reduce the encroachment on farmland resources, but also effectively reduce the emission of harmful gases such as ammonia, reduce the impact of aquaculture on the environment, and achieve the goal of recycling and environmental protection development.

In addition, the feed after fermentation of agricultural waste can also provide more nutrients for livestock and poultry. Traditional feed often has the problem of unbalanced nutrients, while the fermented agricultural waste feed can improve the content of protein, vitamins and other nutrients through the action of microorganisms, provide more comprehensive nutritional support for the growth of livestock and poultry, and improve their immunity and growth rate.

In a production workshop in Mutang Industrial Park, Danzhou, Hainan Province, agricultural wastes such as straw, sugarcane leaves, palm residues, etc., after crushing, degradation, stirring fermentation, puffing and other production line processes, and then come to the end of the production line, it is no longer "waste", but a new type of feeding feed with great nutritional value for poultry animals such as cattle and sheep. A few days ago, the Chinese Academy of Tropical Agricultural Sciences research and development of tropical ruminant livestock fermented total mixed ration feed has been put into production, which not only reduces the pollution of straw burning to the environment, saves the cost of healthy feed production, more effectively solves the problems in the healthy feed industry, and promotes the healthy development of the animal husbandry industry.

"Agricultural waste, such as straw, sugarcane leaves, dried bananas and palm residues, are traditionally incinerated, which fails to use them and pollutes the environment. Using our new technology, these agricultural wastes are fermented, extruded and other technologies to form poultry feed, which not only improves the digestibility of feed, but also adds nutrients according to different feeding needs, making poultry breeding healthier. In the production workshop, researcher Zhou Hanlin, the leading expert of the animal husbandry team of the Chinese Academy of Thermal Sciences, pointed to the sugarcane stems and leaves stacked at the beginning of the production line and told reporters that Hainan sweet corn, cassava and other cash crops are widely planted, and the planting area of sweet corn alone is about 500,000 mu, and the straw resources are abundant.

In the finished product area of the workshop, there are already bagged feed products, which can already be fed directly. According to reports, the finished product is easier to store than traditional forage feed, and can effectively alleviate the problem of winter feed shortage in Hainan. Researcher Zhou Hanlin told reporters that in recent years, with the improvement of people's material living standards and the concept of green food deeply rooted in the hearts of the people, consumers have paid more and more attention to the quality of livestock and poultry products and the addition of feed antibiotics, and the development of healthy feed industry has become an inevitable trend in the development of animal husbandry. In response to the requirements of the animal husbandry industry for green and healthy quality, the animal husbandry research team has developed a fermented total mixed diet feed for tropical ruminant livestock, which is based on the use of microbial fermentation technology, and also specially added ingredients such as southern medicine to replace antibiotic additives, with scientific formula, precise feeding, green and healthy.

The following is a general corn stover fermentation operation process to share:

1. Collect corn stalks: After the corn is harvested, the remaining roots, stems, and leaves are collected to form a certain straw pile. The size and number of straw piles depend on specific needs and available resources.

2. Chopping treatment: The corn straw is minced to make its particles more uniform, which is conducive to the growth of microorganisms during the fermentation process. Shredding can be done using lawn mowers, straw cutters, or other agricultural machinery.

3. Adjust the moisture: Mix the chopped corn stalks with the right amount of water to adjust the moisture content. In general, the moisture content should be kept in the range of 50%-60% to promote the reproduction of microorganisms and the progress of the fermentation process.

4. Inoculant: Add "99 Multifunctional Feed Starter Agent" to the mixture to start the fermentation process. Commonly used starter cultures include acidic lactic acid bacteria, yeasts, etc., which can speed up the fermentation process, reduce the pH value, and improve the availability of feed.

5. Stacking or Loading in Containers: Stack the fermentation mixture in a suitable place or in a special fermentation vessel. If it is stacked in the open air, you need to pay attention to rain and moisture. If a fermentation vessel is used, make sure that the vessel is well sealed to control the oxygen supply and the temperature of the fermentation process.

6. Fermentation process: The fermentation process generally takes several days to weeks to last, depending on factors such as temperature, humidity, added microbial agents, etc. During this period, the mixture in the accumulation or stirring vessel needs to be turned regularly to promote oxygen supply and homogeneous fermentation.

7. Fermentation Complete: When the odor produced during the fermentation process decreases, and the mixture turns dark brown and has a sour taste, it means that the fermentation is complete. The fermented corn stover can be used as feed or for other purposes.

To sum up, the market prospect for turning agricultural waste into feed through fermentation is broad. Fermentation treatment can convert agricultural waste into high-quality feed raw materials, improve the quality of feed, reduce production costs, and bring economic benefits; at the same time, it has good environmental performance, reduces the encroachment on farmland resources, reduces environmental pollution, and can also provide more nutrients for livestock and poultry, improve their immunity and growth rate. Therefore, the feed market after fermentation and treatment of agricultural wastes has broad prospects and has huge development potential and market space. It is hoped that the government, enterprises and scientific research institutions can increase the research and development and promotion of agricultural waste fermentation and treatment technology, promote the resource utilization of agricultural waste, and contribute to the sustainable development of livestock and poultry breeding.
