Straw ammoniated feed production method

First, the benefits of straw ammoniation In the countryside, each year when harvesting cereals, produce a large number of crop straws, such as corn straw, wheat straw, sorghum straw, etc. After the straw is aminated, it can be used to Feeding animals has the effect of “returning from the abdomen to the field”. After ammoxidation of straw, it can increase the nutritional value of straw, and generally increase the crude protein content by 4 to 6%. Second, it can increase the palatability and digestibility of straw, and the general intake can increase by 20 to 40%. The digestive rate is increased by 10~20%, so that the milk production of dairy cows is increased by about 10%. Third, ammoniated straw (referring to urea) has low cost, simple operation and easy promotion. Second, straw ammonification method 1, ammoxidation pool amination method of its specific approach is, (1) select sunny, lee, higher ground, hard soil, low water table, and easy to make, feeding, management Ammonia pool is built locally. The shape of the pool may be rectangular or circular. The size and capacity of the pool are based on the amount of ammoniated straw, and the amount of ammoniated straw is determined by the type and number of livestock. Generally, about 100 kilograms of chopped air-dried straw can be placed per cubic meter of pool. A cow weighing 200 kilograms needs 1.5 to 2.0 tons of ammoniated straw annually. After digging the pool, use bricks or stones to cover the bottom, build walls, and cement the surface. (2) The straw is crushed or cut into small pieces of 1.5 to 2.0 cm. (3) Urea with a straw weight of 3 to 5% is formulated with warm water. The amount of warm water depends on the moisture content of the straw. Generally, the moisture content of the straw is about 12%. The ammoniation of the straw should make the straw. The moisture content is about 40%, so the amount of warm water is generally about 30 kg per 100 kg of straw. (4) Spread the urea solution evenly on the straw, stir it while sprinkling, or spray the urea solution once evenly with a layer of straw. (5) After filling the pool, cover the pool mouth with plastic film and cover it with soil. 2. Ammonia storage method for pits (1) Choose a pit where the terrain is high, dry, hard, with low groundwater level, close to the barn, convenient for storage, and easy to manage. The size of the pit depends on the storage. The cellar can be dug into underground or semi-underground, either in crypt or cement cellar. However, the cellar must be airtight and watertight. The crypt wall must be smooth and smooth. If a crypt is used, 0.08-0.2 mm agricultural plastic film can be used to lay the cellar floor and the four walls flatly, or at the bottom of the raw material before entering the cellar. Layers of 10-20 cm thick straw or hay are used to prevent moisture, and a layer of corn stover is tightly packed around the pit to prevent the soil on the pit wall from entering the feed. (2) Cut the straw into small pieces of 1.5 to 2.0 cm. (3) Preparation of aqueous urea, as above. (4) Straw side of the cellar, spraying urea solution, the method above. (5) After the raw materials are filled in the cellar, cover the raw materials with a layer of straw or crushed straw of 5 to 20 cm thick, cover the soil with 20 to 30 cm, and apply it. When the cellar is sealed, the raw materials must be 50-60 cm above the ground to prevent the infiltration of rainwater. Always check, if found to repair cracks. 3, the size of the plastic bags of ammonia bags plastic bags to facilitate the use of good, plastic bags are generally 2.5 meters long, 1.5 meters wide, it is best to use double plastic bags. The cut straw, with a prepared urea aqueous solution (the same method as above) evenly sprayed, filled with plastic bags, sealed bags mouth, placed in a sunny place. During storage, it should be checked frequently. If smelling ammonia smells at the mouth of the bag, it should be fastened again. If the plastic bag is damaged, it must be sealed with tape. Third, the quality of ammoniated feed identification After a certain period of straw ammoniating, you can open cellar feeding. The length of ammoniation depends on the temperature. The temperature is less than 5 degrees, it takes more than 56 days; the temperature is 5 to 10 degrees, it takes 28 to 56 days; the temperature is 10 to 20 degrees, it takes 14 to 28 days; the temperature is 20 to 30 degrees and takes 7 to 14 days; The temperature is higher than 30 degrees, only 5 to 7 days. Ammoniated straws should be quality-checked before they are fed to livestock. In general, the aminated straw should be apricot-yellow, the aminated cornstove should be brown, and the texture should be soft and fluffy. Feel. The ammoniated straw has a pungent smell and a pungent ammonia smell. Ammoniad corn stalks have slightly different odors, both silage acid and pungent ammonia. If ammoniated straw is found to be mostly mouldy, it cannot be used to feed livestock. IV. Feeding method of ammoniated straw After the cellar is opened, the ammoniated straw qualified by the quality inspection needs to cool in the cool and ventilated place for a few days and eliminate ammonia smell before feeding. When ammonia is released, the ammoniated straw that has just been taken out should be placed away from the livestock house and shelter so that the released ammonia can irritate human and animal respiratory tracts and affect the appetite of livestock. If the humidity of the straw is small and the weather is cold, the ventilation time should be longer. When feeding, the ammoniated straw to be fed every day should be taken out and put into ammonia 2 to 3 days before feeding, and the rest should be sealed again to prevent the ammoniated straw with high water content after releasing ammonia in the short term. Feeding must be moldy and go bad. Ammoniated straw is only suitable for feeding ruminants such as cattle and sheep, and is not suitable for feeding monogastric livestock, horses, quail, donkeys, and pigs. When the ammoniated straw was initially fed, the livestock was not adapted, and on the first day of feeding the ammoniated straw, 1/3 of the ammoniated straw was mixed with 2/3 of the non-ammonified straw, and gradually Increasing, livestock no longer want to eat non-ammonified straw after a few days. The feed of ammoniated straw can generally account for 70-80% of the cattle and sheep's diet. The livestock can drink water only half an hour or 1 hour after feeding the ammoniated straw. Hungry livestock should not be fed in large quantities. In areas where conditions permit, it may be appropriate to mix some feeds containing higher carbohydrates, and feed them with a certain amount of minerals and silage, so that the role of ammoniated straws can be fully utilized to increase the utilization rate. If livestock poisoning is found, 500 grams of vinegar can be detoxified.
