Inquiries: When silage open storage is reasonable? Answer: In winter, the farms have started to feed sheep and sheep with silage. Silage is an indispensable and high quality feed for cattle and sheep. Therefore, it can not guarantee the high quality of silage, improve its utilization, reduce unnecessary waste, and has a very close relationship with the reasonable selection of open silos. In the production practice, the following principles should be followed when selecting the silo opening time and the method of access.

The first is to choose a reasonable opening time. That is, 30 to 40 days of anaerobic fermentation after completion of the silage process can open the cellar. Under normal circumstances, before and after the winter, the relatively cool air season open cellar is more conducive to the preservation of the whole cell silage and the quality of silage. According to the actual conditions in Gansu Province where the natural conditions and temperatures vary greatly, the silage in the Hedong area can be opened in about 30 days after the cellar is sealed. The silage in the Hexi area can be opened in about 40 days after the cellar is sealed, and the Gannan and Qilian Mountains can be opened. It is advisable that the area be opened in about 50 days after the silo is sealed. The second is to choose a reasonable method of access. Once silage is opened, it must be taken every day. Care must be taken to prevent freezing, rain, and snow from seeping. At the same time, it is necessary to pay attention to subsection open cellar, subsection access, each paragraph should be achieved from top to bottom stratification, pay attention to avoid opening the whole cellar, wormhole access, in order to reduce the use of silage and contact with air in the cellar , to prevent the fungus and other bacteria on the silage hazards. The third is to choose a reasonable amount of access. Under normal circumstances, farmers should adhere to the principle of taking doses on a daily basis when accessing silage, and how much should be used. The thickness of grass removal per day should not be less than 20 cm to ensure its quality. The fourth is to choose a reasonable method of safekeeping. After the farmers have finished taking the necessary silage grass every day, they must pay attention to opening the silage section in a timely manner with a plastic film to cover the pressure, with dust-proof soil, rain and snow falling into and large amounts of air to ensure the quality of silage. A small amount of rotted and degraded silage grass in the pit cannot feed livestock. It is necessary to remove the pits in time and move them away from the pit, so as to prevent contamination of the silage in the pit and poisoning caused by accidental feeding of livestock.
