Guaranteed ammonia storage time It takes a certain time for the crude fiber in the straw to decompose under the action of ammonia. The fermentation time of ammoniated straw should be flexibly controlled according to the temperature conditions of different seasons.
Careful identification of quality The quality of ammoniated straw is mainly identified by sensory. The ammoniated straw is brownish yellow, has a mushy aroma, and the ammonia smell is also strong, and the hand touch is soft. The color of the immature straw is as sweet as ordinary straw, the ammonia smell is lighter, and the texture does not change significantly. The old ammoniated straw becomes darker in color and the ammonia smell becomes lighter. If the plastic bag leaks the straw, it will be mildewed, the color will become white, gray, and even black and agglomerate with rot, so that the straw should not be used as feed.
Free feeding, proper amount of ammoniated straw is roughly the same as ordinary straw feeding, and advocates free feeding. Because of the good palatability of ammoniated straw, most cattle began to like it very much and can completely replace un-ammonia straw. Individual cattle are extremely sensitive to ammonia. At the beginning, 1/3~1/2 un-ammonia straw can be blended, but the amount of ammoniated straw is 40%~60% of the forage.
Dissipate ammonia gas. Take it out of the ammoniation tank as needed before feeding, and put it in a cool place to disperse ammonia. Drying for 10~12 hours on a sunny day, it is necessary to dry for more than 24 hours on a rainy day. It is better to ammonia the straw with ammonia after the ammonia is dissolved without irritating the eyes and nose. But do not dry too much, so as not to affect the feeding effect of ammoniated straw. Seal the ammoniation tank after each reclaim. Ammonia straw can be stored in the pool for a long time, but it is necessary to check the behavior of damaged plastic cloth, such as rodent, human and animal trampling, wind and rain, and find that holes should be sealed with tape in time.
With supplemental feed, due to the energy of ammoniated straw and the increase of non-protein ammonia, when feeding ammoniated feed, it should be properly matched with non-degradable protein such as bean cake, cottonseed cake and distiller's grains, and properly supplemented with vitamins and minerals. Feed to ensure the metabolic balance of the carcass.
The difference between the use of ammoniated straw can only be used as cattle and sheep ruminant livestock feed, the effect on pigs is very poor, and unweaned yak, lamb because the microbial ecosystem in the rumen has not yet fully formed, must be used with caution.
Observation and treatment If the cattle and sheep are found to have reduced or stopped ruminant due to improper feeding, excessive salivation, restlessness, trembling, gait instability and other symptoms of ammonia poisoning, stop feeding immediately and smash the cattle and sheep to the outdoor ventilated and cool place. At the same time, 1 kg of vinegar, 0.55 kg of sugar and 3 to 5 kg of water can be used to relieve the symptoms of ammonia poisoning.
