Whole straw high efficiency ammoniated feed technology

The protein content of the whole straw after amination was as high as 8.15%, close to the level of corn crude protein. Crude protein increased by 6.07%, crude fiber degradation rate was 3%, which was significantly higher than 4.05% and 1.05% of aminated straw in the cellar, and the cost was low. Labor and time were saved, and the people were willing to accept it. The technical points are as follows. l. Ammonia table preparation. Choose a sunny bench that is sunny and well ventilated and leaves the village and barn. The ammoxidation platform is 10 cm above the ground, and the countertops are neat and compact, with ditches on both sides. Ammonia table area of ​​40 meters 2 (202 meters). ? 2. Ammonia-laden plastic pipe laying. Holes were placed on both sides of the tube, and the distance from the eye to the far point was 16, 13, 10, and 7 cm. ? 3. Incoming material. Straw moisture before feeding should not exceed 40%. The entire straw is weighed into small bundles weighing about 30 kg, alternately in vertical and horizontal directions. Stacking rakes are 20 meters long, 2 meters wide and high, and they are curved. ? 4. Cover the plastic cloth. After the pilings are completed, the plutonium is covered with a plastic sheet and covered from the top down, the bottom is compacted with soil, and the infusion port is left while blocking. 5. Infusion of ammonia. The amount of liquid ammonia was calculated as 3% of the amount of straw and the actual amount was 17%. After the ammonia-infused plastic pipe is input all at once, it enters the ammoniation period. ? 6. Ammonia period. Through experiments, it is considered that the ammoniating period of the whole straw is suitable for different regions of northern China. The temperature varies between 10 and 18°C ​​and takes 20 to 22 days. When the temperature is 20 to 25°C, it takes 15 to 20 days. The temperature is 5～ 10 °C, take 35 to 40 days. Ammoniated corn, sorghum stalks than wheat, gluten straw extended 2 to 3 days. The entire stack of straw is 80 cubic meters (20 meters, 2 meters, and 2 meters). Summer temperatures above 25°C require 12 to 15 days, spring and autumn temperatures at 20°C take 18 to 20 days, winter temperatures above 15°C take 25 days, and temperatures below 10°C take 35 to 45 days. During the amination, it is necessary to prevent the plastic cloth from being crushed and damaged so as not to affect the ammoxidation effect. At the same time, it is necessary to observe the degree of ammoniation of the straw regularly. When the straw is yellow-brown, it indicates that the ammoniation is complete. 7. Intensification treatment. Intensification is an important part of improving the nutrition of ammoniated feed. In the middle and late period of ammoniation, one-ten thousandth of raw materials plus 50 kilograms of boiling water dilute stimulant are input at one time. The intensification period is 3 days. 8. Ammoniad straw feeding. After complete ammoniation, the plastic cloth is opened for baling and allowed to cool for 12 hours. After the free ammonia is dispersed, it can be chopped and fed. From 1996 to 1999, demonstrations were carried out in different experimental cattle farms in Wutai County of Luzhou and Luyang in Luliang District. 5320 heads of fattened cattle were promoted, and 24.42 million kg of straw were aminated. The economic benefits were significant. This technology is suitable for the development of large-scale cattle breeding industry and is not limited by geography and climate, as long as it has a large amount of food crop straws and is close to where fertilizer plants have ammonia.
