1. There are two kinds of silage silo and cellar silage, that is, the harvested green corn stalks are crushed to 1 to 2 cm, and the water content is adjusted to 67% to 75% (that is, the raw materials are taken from the fingers Visible drops of water, but not dripping), into plastic bags or pits, compacting the well vents clean air, to prevent mold contamination, seal and save 40 to 50 days to open bags (cellar) feeding.
2. Yellow-stemmed dry corn stalks Livestock do not like to eat, the publication rate is low, the palatability after yellowing is improved, the utilization rate is increased by 2 times. First, a thousand corn stalks should be weighed as short as 3 to 4 centimeters and put into a cylinder. Add appropriate amount of warm water for 2 days.
3. There are two types of amination, heap storage and pit storage. When stacking, a plastic film can be used to lay on the ground. The corn stalks, which are shorter than 3 to 5 centimeters, are piled on top. Then they are covered with a plastic film and compacted with soil on all four sides. In the top of the wind, leave a mouthful of 10 to 12 kg of ammonia per 100 kg of corn stalks. Dig a long, square, or round pit first when storing pits, and put a plastic sheet on the bottom of the pit. After the straw is loaded, it is sealed tightly with a plastic film lid and 15 kg of ammonia is added per 100 kg. The temperature was stored at 20°C for 7 days, at 15°C for 10 days, and at 5°C to 10°C for 20 days. After 30 days of OC, straw became brown. At this time, the top film is peeled off, and the net ammonia taste is added to the ruminants such as cattle and sheep, and the maximum amount can account for 40% of the diet.
4. Alkalinization includes sodium hydroxide treatment, liquid ammonia treatment, urea treatment and lime treatment. Lime treatment method is simple and easy, with less investment and good effect. 100 kg of water plus 1 kg of lime, stirring continuously, to be clarified after the supernatant, according to the ratio of the solution and feed 31 in the tank after stirring evenly compacted. 80 hours in winter and 30 hours in summer can be fed directly.
5. Saccharification in corn stalks is as short as 3 to 4 cm. Yeast is first opened with water and added to 100 kg of water. Stir in winter and use 30 to 40°C warm water. The yeast liquid is evenly sprayed on the short corn stalks, loosely piled into a 30-60 cm square bowl or cylinder, closed for 1 to 3 days to feed.
6. Fungal feed After the corn granules are pulverized into powder, the edible fungus culture material is added to cultivate the edible fungus. The leftovers are the feed for the fungus. When the feed is used, the pigs account for 10% of the diet and the finishing pigs may account for 20. % ~ 30%, feeding cattle can account for 30% to 50% of the diet.
