At present, the development of straw utilization is limited, and most of them are burned, or used for households to warm fire. If straw resources can be effectively developed, biomass energy can be fully utilized. The north is long in winter and there is no grassy period for more than 6 months. Goose is a grass-eating animal and it is resistant to rough feeding. Coupled with the characteristics of goose laying for half a year for half a year, northern breeding geese farmers mostly use roughage in the winter and supplemented by fine feeds. The fermented yellow storage can effectively increase the nutritional value of crop stalks. Increased palatability, while also reducing the cost of feeding. The traditional yellow storage feed generally uses pit storage, pool storage, tower storage, and urn storage, which are not only large in quantity, but also are not suitable for small-scale breeding geese farmers. Combining the actual characteristics of the production of goose, we have developed a yellow bag storage technology for corn stalks. Because of its low material consumption and simple production, it is ready for use, convenient for storage, and not only saves space, but is also available all year round. Therefore, it is More and more farmers are accepting it.
First, the production principle
Corn stalks are processed and bagged to seal. The principle of Huangcun Feed Fermentation is to degrade the cellulose, hemicellulose and lignin in the straw in a large amount by adding a certain amount of highly active microbial compound inoculum under appropriate anaerobic conditions of temperature, humidity, and hermeticity. The production of sugars, which in turn is converted to lactic acid and volatile fatty acids, reduces the pH of the stock to 4.5 to 5.0, inhibits the enzymatic hydrolysis of the ester bonds of harmful microorganisms such as butyric acid bacteria and spoilage bacteria, and increases the softness of the straw. And swelling. After storage in the bag, corn stalks are converted into high quality roughage that gooses like to eat, effectively increasing the feed value of the original straw. As a bag of corn stalks that are stored well, they can be opened and ready to eat without causing problems such as spoilage. As long as they do not leak gas or enter water, they can be stored for long periods of time.
Second, the production method
1. Prepare the facility: Choose a thicker double polyethylene film in the plastic bag, approximately 1.5 meters in length. One side of the polyethylene rope is fastened and used.
2. Crush: If conditions permit, try to select fresh straw without any mildew. In order to have a good micro-reservoir effect, the straw must be shortened to 1 to 2 cm before storage, which is beneficial to compaction and discharge of excess gas to form closed conditions. It is necessary to pick out hard parts and other hard substances mixed in, such as stones, iron wires, etc., to prevent the plastic bags from being punctured. Also note that oil, dirt, and dirt should not be mixed in to prevent local deterioration of the yellow stock.
3. Prepare the broth: Select the appropriate sugars and fermentation preparations or probiotics. Mix well and mix well according to the instructions.
4. Add water: Add water to the crushed corn stalks to lay the moisture base for later fermentation. The standard for adding water is to feel wet hands when holding hands lightly, but it is not appropriate to drip. If the water content is too low, it will not be compacted, which will affect the activity of the microorganisms and cause fermentation failure. If the water content is too high, it will tend to harden and the quality of the yellow stock cannot be guaranteed. Generally, when the water content of the straw is 65% to 75%, it is most suitable for lactic acid bacteria breeding.
5. Bagging: compaction layer by layer when bagging. Each 15 cm thick straw, sprinkled with a layer of sugar and starter mixture, layer by layer and compaction, can be artificially compacted. Note that during the compaction process, do not break the plastic bag to prevent air leakage. When it is attached to the bag mouth, the bag mouth is repeatedly tied with the rope after being strongly compacted. Use pre-prepared tape to seal the damaged plastic bag. Immediately into the storage period.
6. Storage: The success of storage is closely related to environmental conditions, with temperature being an important part. The storage temperature is preferably between 15 and 25°C. The temperature is too low, the activity of lactic acid bacteria is low, and the fermentation is slow. If the temperature is too high, the yellow storage will decay and decay. In addition, during the storage process, the inspection of the sealing condition of the plastic bag shall be strengthened to prevent the destruction of rats, insects and birds. If any damage is found, the loophole shall be repaired in time. Generally, it can be opened in 3 to 5 weeks.
7. Qualification: The quality corn yellow stock has a bright yellow color, sweet and sour taste, and is soft and sticky, with a pH of 3.4 to 3.8 and a moisture content of 65% to 75%. Because the yellow storage is not limited by the moisture content of the straw, it can be done all year round. It can well satisfy the demand for high quality crude fiber feed in the winter of northern goose breeding, effectively reducing the cost of breeding goose breeding, and it is a very popular feed. Storage technology.
