How to store goat green feed

Green feed storage needs to pay attention to the following matters:

(1) Harvest silage at the right time. At this time, not only the content of water and carbohydrate in green feed is suitable, but also the highest yield and nutrient utilization rate can be obtained per unit land area. In the vast agricultural areas of China, it is common to scrape off geese for silage and immediately harvest corn stalks. At this time, more than half of the corn leaves are still green. Sweet potato vines can be collected in front of the box or 65438+ 0-2 days before harvesting. Gramineae grass and wheat can be mowed in the early stage of smoking, and leguminous grass can be mowed in the flowering stage. (2) Adjusting the water content of silage The water content of silage is one of the important factors that determine the success or failure of silage, and the water content of silage is generally 65%-70%. Available: ① Twist the corn stalks without corn forest with both hands. If there is juice oozing from corn stalk, it means that its water content is about 70%, which is suitable for silage. (2) If the corn stalk oozes more juice, it means that its water content is high, and it should be dried for half a day or a day before silage. (3) If the corn stalk does not ooze juice, it means that its water content is not enough, and some water should be properly supplemented when silaging. (3) The chopped silage must be chopped to facilitate compaction. In addition, in the process of chopping, due to the exudation of juice, the surface is moist, which is conducive to accelerating the reproduction of lactic acid bacteria and improving the digestion of sheep. The fineness of chopping is about 0. 5cm, and it is best not to exceed 1cm. (4) When the silage is filled and pressed, it should be chopped and stored at the same time, and compacted for one layer after loading. Pay special attention to the corners and surrounding areas of ditches or kilns, that is, where tractors can't press and where people step on them. Try to fill it in a short time. The tighter the silage is packed, the more thoroughly the air is exhausted, and the better the silage wall is made. (5) Sealed silage should be sealed tightly and buried immediately after filling. Generally, silage is required to be packed at about 1 m above the ditch or kiln mouth, and then covered with plastic film and then covered with soil (the soil layer is 30-50m thick). The top of the ditch should be roof-shaped to facilitate drainage. During the whole silage process, air intake and water addition are not allowed. After 20-30 days, the thick soil layer on it sinks and cracks may appear in the soil layer. Therefore, it is necessary to regularly check whether there are low-lying or cracks in the top soil layer of the city. In order to prevent the backflow of soup gas and water, it is necessary to fill it up and seal it in time. (6) Management around the city or kiln. Dig ditches and drain water one meter away from the ditch wall to prevent rainwater from infiltrating. In the rainy areas in southern China, a shed should be built above the silage ditch, especially when unsealing to prevent rainwater from entering. (7) Silage ditch method: Silage ditch is a horizontal tunnel structure. The trench is 10-20m long, 4.5-5.0m wide at the top, 4.0-4.5m wide at the bottom and 2.5-3.5m high. This trench is suitable for professional households or sheep farms with more sheep. In order to improve the efficiency of loading silage into the trench, facilitate the unloading of silage transport vehicles and the compaction of silage by vehicles, it is not necessary to build fences at both ends of the trench. The side walls and bottom of the trench can be made of masonry or concrete. The surface of the wall should be smooth. If an earth trench is used, plastic films can be laid around and at the bottom of the trench. In areas with high groundwater level, semi-underground silage ditches can be used. The bottom of the city should be 0. 5 meters higher than the groundwater level. With the filling of silage, both ends of the ditch should be built with planks or bricks, and the outside should be filled with soil. Plastic bag silage method: This method is suitable for families with a small number of sheep. Generally, non-toxic agricultural polyethylene double plastic film with a thickness of 0.8- 1.0 mm (8- 10 line) is selected. The size of the bag can be determined as required. General 1 kg plastic film can make 3-4 bags. When filling the bag at the entrance of the city, it must be full and tightly pressed. The mouth of the bag must be tightly tied and sealed, so that the air in the bag is as little as possible. In order to prevent rats from biting plastic bags, resulting in air leakage in the bags and deterioration of silage, the filled plastic bags can be buried in a ditch dug in advance, covered with a layer of soil, and dug out bag by bag when used. Once the silage ditch is opened, it must be used continuously every day. Dig as much as you want. The opening should be as small as possible to minimize the exposure of silage to the air. Open the cover at any time to prevent rain from invading.
