First, the benefits of straw ammonification 1. Save food, reduce animal husbandry dependence on food. 2. Improve palatability and increase livestock feed intake on straw. 3. It can increase the digestibility of straw organic matter by 10-12% and increase the crude protein content 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. Second, the production of straw ammonification feed 1. Ammonification of raw material selection: a variety of good texture, no mildew, water content does not exceed 13% of crop straw, such as straw, corn stover, straw, agricultural and sideline products such as chaff And cottonseed husks can be used as amination of raw materials. 2. Ammonia source and dosage: Various agricultural nitrogen fertilizers, such as urea, ammonium bicarbonate, etc., the most commonly used is urea, its amount is 4% -5%, ammonium bicarbonate 8% -12%. 3. Ammonia container: 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 stalks cut to 5 - 10 cm, the first to add urea at the rate of 4-5 kg ​​of urea per kilogram of straw, fully dissolved in 40-50 A solution of kilograms of water is sprayed on the stalks, filled with a layer of spray, and continuously sprayed and sprayed, while being pressed tightly, while being mounted 30 to 50 centimeters from the pit, the top is tapered, covered with a film, and wet mud The interface between the sealing film and the container. To prevent rat damage, soil can be pressed onto the membrane. Third, the management and utilization of ammoniated straw 1. Sealing inspection: During ammoniation, it is necessary to inspect the film for damage and leakage. In particular, it is necessary to prevent the rat from blowing the film and find that the damage should be repaired in a timely manner. 2. Ammoxidation time: The length of ammoniation 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 in color, odor-smelling, loose and soft texture, and 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: Ammoniad straw can be opened after a specified period of time. Take out and spread ammonia on a well-ventilated concrete floor for 1 day. Only when it has no pungent ammonia flavor, can it be fed. Containers should still be sealed after use, avoid water. 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 winter. For adult cattle, especially for rural cattle and even beef cattle, as long as little concentrate or oil cakes (bean cakes, cotton cakes, etc.) can be safely used for winter, they will not be lost. To achieve better production results, a certain amount of feed must also be used. China Agricultural Network Editor
