First, straw ammoniating cut the crop straw into small pieces 2 to 3 centimeters long. After layered compaction, add 15% ammonia water 12 to 15 kilograms per 100 kilograms of straw, spray ammonia layer by layer, and finally seal it tightly.

Second, the amount of aminated straw fed ammoniated straw accounts for 40% to 60% of the amount of forage. At the beginning it is possible to incorporate 1/3 to 1/2 unamalted straw in the ammoniated straw. When feeding aminated feed, it should be matched with bean cakes, cottonseed cakes, distiller's grains, etc., and supplement feeds rich in vitamins and minerals. Ammoniated straw can only be used as feed for ruminants such as cattle and sheep, but it should be used with caution for non-weaned calves and lambs. Pigs have poor utilization of aminated straw and generally do not advocate feeding.
Third, pay attention (1) ensure ammonia storage time. According to the air temperature conditions, the fermentation time of ammoniated straw can be controlled flexibly. Generally, ammonia storage at 25-30°C for 7 days, ammonia storage at 20°C for 25 days, and ammonia storage for more than 40 days in winter.
(2) ammonia storage quality requirements. The ammoniated straw is brownish in color, has a scent, has a strong ammonia smell, and is soft in texture.
(3) Pay attention to the method of taking the subjects. Ammoniad straw was removed from the ammoxidation tank according to the required amount before feeding and placed in a cool place. Normally, it is allowed to air for 10 to 12 hours in sunny days and over 24 hours in cloudy and rainy days. It is better to have ammonia smell but not to stimulate the eyes and nose. After each withdrawal, seal the ammoxidation tank.
