What Are the Uses of Peanut Vines? A Full Analysis of the Latest Utilization Methods
Peanut vines, also called peanut straw, peanut vines, peanut tendrils and so on, are the stems and leaves of the peanut, an annual herbaceous plant of the genus Arachis in the Fabaceae family. In the past, people would usually just pile up these peanut stems and leaves and burn them, or throw them away as waste. But with the development of science and technology, people have found through research that peanut vines are in fact rich in nutrients. These peanut vines can be used as feed for herbivorous animals. Below, Qinnong Web takes everyone to take a look at what uses peanut vines have!
What are the uses of peanut vines?
Peanut vines are rich in nutrients. Their crude protein content is 1.6 times that of pea vines and 6 times that of rice straw. The energy produced by livestock and poultry eating 1 kilogram of peanut vines is equivalent to the energy produced by 0.6 kilograms of barley. Generally, 300 kilograms of peanuts produced per mu can yield 300 kilograms of peanut vines, and when used to feed livestock it is equivalent to the feeding effect of 180 kilograms of barley. At the same time, peanut vines are not only rich in nutrients but also low in price and soft in texture, and can be eaten by livestock and poultry.
Silage method for peanut vines
1. Harvesting and transport: Peanut vines cannot be directly eaten by animals as food; they need to go through a certain amount of processing to increase their digestibility and absorption rate. Processed peanut vines can also enhance the comfort of the taste. This requires timely harvesting after the peanuts mature and timely transport of the peanut vines to the silage site to prevent water loss caused by taking too long.
2. Crushing and cutting short: Crush the peanut vines or cut them into small pieces of 2-3 cm to facilitate trampling, compacting and air expelling when loading the silo, while also settling more evenly, with less nutrient loss, and helping lactic acid bacteria grow and speeding up the silage process.
3. Mixing materials and loading the silo: For every 5 tons of peanut vines, use 1 kilogram of silage fermentation agent. Dilute and mix the fermentation agent with rice bran at about 1:10, adjust the moisture to 60-70%, and then begin loading the silo. While loading the peanut vines, sprinkle the fermentation agent, trampling as you load, and the more firmly the edges are trampled the better.
4. Sealing and fermentation: The fermentation process should ensure good sealing. When making silage by the plastic film covering method, attention should be paid to covering with soil or other heavy objects after the final plastic film covering. The film should be strictly sealed to prevent air leakage. Generally, fermentation can be completed in 3-4 weeks.
Benefits of peanut vine silage
1. Preserving nutrients: After fermentation, peanut vines not only retain the softness and juiciness of green feed but also reduce nutrient loss to the greatest extent.
2. Easier to store: After fermentation into silage, peanut vines are easier to store, and even in winter the supply of green feed can be guaranteed.
3. Rich in nutrients: During the fermentation of peanut vines, a large amount of bacterial protein and trace elements are added, making the nutrients they contain even richer.
4. Good palatability: After fermentation, peanut vines have a fresh aroma and excellent taste, are more favored by livestock and poultry, and also greatly save feed costs.
The above is Qinnong Web's introduction to the functions and uses of peanut vines. It can be seen that the process of peanut vines turning waste into treasure from the past to now precisely reflects the improvement of people's level of awareness. It is believed that with the continuous progress of science and technology, there will be more and more things like peanut vines that go from having no use to being useful, and more and more uses can be developed from them.
