In simple terms, green stored corn stalk feed is a kind of feed that is made by compressing and stacking fresh corn stalks in a sealed and non-permeable storage facility and fermenting them with mainly lactic acid bacteria. It is rich in nutrients, has good palatability, and is very suitable for cattle and sheep breeding. So what is the specific production method? Let's find out together.
1. Material Selection
In order to produce high-quality green stored feed, it is necessary to select good corn stalks. Choose corn stalks with some green color as raw materials for making green stored feed, and harvest the stalks immediately after harvesting the crops.
2. Cutting
Use a straw cutter to cut the corn stalks into pieces about 2-3 centimeters long. The moisture content of the cut stalks should be suitable, and the testing standard is the first item in the technical requirements for corn stalk green storage mentioned earlier. After cutting, it should be filled in as soon as possible to avoid affecting its nutrient content.
3. Preparation of Green Storage Pit
Green storage pit is the most commonly used green storage equipment, generally divided into two types: rectangular green storage pit and circular green storage pit, but in practical applications, circular green storage pit is more common. After preparing, the green storage pit should be carefully cleaned, and the remaining materials inside should be removed. The surrounding area should also be cleaned and the chaff cutter installed. The green storage pit should not face west or south.
4. Filling
First, lay a 10-15 centimeter thick layer of straw or soft grass at the bottom of the green storage pit, and then fill it in layers with green storage raw materials. Each layer should be compacted by 15-30 centimeters, especially paying attention to the edges and corners. Repeat this process for each layer.
5. Sealing
After filling the green storage raw materials, they should be 50 centimeters above the pit and then compacted. Next, use plastic film to seal the top and cover it with 50 centimeters of soil. During the settling process, cracks may form, so timely sealing is important. After 40-60 days of fermentation, the feed can be given to livestock.
6. Post-opening Management
Firstly, the extraction surface should be kept clean to reduce the retention of air and prevent secondary fermentation. Secondly, after each extraction, it should be sealed as soon as possible to reduce the retention of air and prevent aerobic deterioration.
In summary, green stored feed made from corn stalks has minimal nutrient loss and can retain 90% of the original nutrients of the corn plant, making it a high-quality feed for cattle and sheep. Furthermore, its production cost is relatively low, so it is beneficial for farmers to learn and master the production method to effectively reduce breeding costs.
This concludes the information about the production method of green stored corn stalk feed.
