(A) The benefits of ammoniating straw. (1) Save food and reduce the dependence of animal husbandry on food. (2) Improve palatability and increase the feed intake of straw to livestock. (3) The digestibility of straw organic matter can be increased by 10-12%, and the crude protein content can be increased by 1 time. (4) The material is easy to take and the method is simple and easy. (5) Reduce feeding costs and increase economic efficiency. (b) The production of straw aminated feed. (1) Selection of ammoniated raw materials: Crop stalks with good texture, no mildew, no more than 13% moisture content, such as rice straw, corn stalk, wheat straw, and agricultural and sideline products such as chaff and cottonseed husks can be used for ammoniation. Raw materials. (2) Ammonia sources and amounts: Various types of agricultural nitrogen fertilizers, such as urea, ammonium bicarbonate, etc., are most commonly used as urea, the amount of which is 4%-5%, and ammonium bicarbonate 8%-12%. (3) Ammonia containers: There are several kinds of cement ammoniation tanks, cylinders, and plastic bags. The construction of ammoniated (silvery) pools: 1 As far as possible, it should be built in places with high topography, solid soil, and dry leewardness. It is necessary to avoid places where people and livestock live, as well as to get close to the sheds and to facilitate access. It can also be built indoors. 2 built pool method: generally more semi-underground rectangular grid cells. Dig a rectangular wall pit with four vertical walls in the selected location. The volume can be determined according to the number of livestock. Then build the brick wall along the wall and build a partition in the middle. The brick wall is 50 cm above the ground. The flat brick or broken brick is laid flat, and the walls and the bottom are cemented. The cement pool is made of two grids and two grids are recycled. Use one grid and one grid. 3 ammoniation method (urea ammoniation method): Straw or corn stover cut short 5-10 cm, the first to add urea at the ratio of 4-5 kg ​​urea per 100 kg of straw, fully dissolved in 40-50 A solution of kilograms of water is sprayed on the stalks, filled with a layer, sprayed one layer, and continuously sprayed and sprayed, while being tightly fitted, until the cellar mouth is mounted 30-50 cm, the top is tapered, covered with a film, and wetted The interface between the mud sealing film and the container. To prevent rat damage, soil can be pressed onto the membrane. (3) Management and utilization of ammoniated straw. (1) Sealing check: During the ammoniation period, check the film for leaks and breakages. In particular, it is necessary to prevent rats from biting the film and find that the damage should be repaired in a timely manner. (2) Ammoxidation time: The duration of ammoniating is closely related to the ambient temperature, generally 2-3 weeks in summer, 3-6 weeks in spring and autumn, and more than 8 weeks in winter. (3) Quality appraisal: According to the sensory inspection, straw with good quality can be used for feed without mildew, yellowish-brown color, odor paste, loose and soft ground, pungent ammonia smell, on the contrary if you see the straw gray or brown There is a pungent odor, and the straw sticks into pieces and cannot be used as feed. (4) Access: After the ammoniated straw reaches the specified time, it can be opened and removed. After being taken out, ammonia is put on a well-ventilated concrete floor for 1 day. Only when it has no pungent ammonia smell, can it be fed, after each time it is used Containers should still be sealed and water should not be allowed. The ammoniated straw can also be taken out all at once, spread out to dry, and then re-stacked in the corner of the empty room or bar, covered with a film to prevent the sun and rain, how much to take when feeding. Ammoniated straw is a good feed for the winter. For adult cattle, especially rural cattle and even beef cattle, as long as little concentrate or oil cakes (bean cakes, cottonseed cakes, etc.) can safely survive the winter, they will not be able to get rid of them. To achieve better production results, you need to match a certain amount of feed. China Agricultural Network Editor
