With the development of the aquaculture industry, how to develop a feed source is a very real problem for a large number of farmers. However, at present, many green feeds are consumed in vain, and some are burned after being dried up. This wastes resources and pollutes the environment. A simple way to return straw to the field is to make silage. Fresh silage, freshly harvested corn straw, wild grass and other green feeds are silaged to maintain the original nutrients, enhance palatability, have a long storage time for silage, have a small feed nutrient loss, have a small storage volume, and are simple to produce. It is convenient to use; it has aromatic sweet and sour taste, rich nutrition, can increase the feed conversion rate, can solve the lack of livestock green fodder in winter and spring withered grass, ensure the normal growth and development of livestock, and improve the fertility rate and the survival rate of their mating. To make green fodder, we must first establish a silo. The silo must be built on a high ground, solid soil, low groundwater level, and away from the pool and pit. The silo can be made into a round shape and a rectangular shape, surrounded by bricks, and sealed with a plastic film. All kinds of green fodder require about 60% moisture content of raw materials. In the cellar, a layer of material is applied to compaction, and the large pit can be mechanically compacted. In order to eliminate the inter-material air, the lactic acid bacteria cause anaerobic conditions. The middle part of the stack should be 1-2 meters higher than the cellar. After the round top is formed, it should be covered with a plastic film. Then it should be sealed with soil. The thickness of the cover should reach 30-40 cm. The raw material in the pit will sink after a few days. The occurrence of cracks should be timely sealed with soil and prevent air leakage. After 30 days of mature fermentation, green feed can be opened in the cellar. After opening the cellar, it is first examined. If the green feed is yellow-green and has a distiller's grain smell or fruit aroma, the silage is successful. If the beverage mold deteriorates, it cannot be used. In order to prevent livestock poisoning after eating. When feeding animal husbandry, how much to eat, with the use of taking fresh; fresh food after grazing in a timely manner to prevent loss of appetite, winter and spring feeding effect is good, because the temperature is high, open storage is not easy to save , remove the material odor. Winter and spring, such as green feed ice, should be thawed after feeding; silage has laxative effect, can not be pure feed, pregnant animals should be fed less to prevent miscarriage. Such as green feed acid high, available 3-5% lime milk or 9-10% of baking soda water, according to the weight of silage added 10-20%, fully stirred evenly, and then fed after neutralization. The top should be covered after each reclaim so as to prevent the inflow of rain and snow and prevent the deterioration of mildew.
