Silage is more resistant to storage than fresh feed. It has higher nutritional value than dry feed. Its scent is sour, tender and juicy, nutritious, palatable and conducive to long-term preservation. It should be regarded as one of the high-quality feed for cattle raising.
Most cattle farmers know how to process silage, but not many people can do it well. The color of the feed is dark yellow and the smell is pungent. Especially in summer, it is very prone to rot and deterioration, which seriously affects normal feeding. Today, I will pass a few tips to tell you how to process cattle silage.
Suitable for moisture
In order to produce a sour and delicious silage, the control of moisture is very important, and the quality of silage made only when the water content is around 65%~70% is the best.
If the water content is high, the silage is prone to decay and deterioration.
If the water content is low, the silage cannot be sufficiently fermented and the taste will be deteriorated.
Water can be measured with a water meter if conditions permit, and moisture can be estimated by sensory without a water meter.
If the water is high, it can be aired properly. If it is unconditionally aired, some rice husks or other hay can be properly sprinkled when the tank is filled.
When the moisture content is low, spray water can be sprayed, the water quality must be clean, otherwise, it will easily rot and deteriorate. The corn stalk with lower moisture is generally older, and some fermenting bacteria can be added in the water, which can improve the fermentation effect.
The length of the feed should be moderate
Before silage, corn stalks or pastures should be shortened, and a small section of 1~2 cm should be used.
If it is too long, it is not convenient to compact the air remaining inside, which makes it easy to spoil and can not be fully fermented. Third, when you feed the cow, you need to process it again.
For corn stalks or pastures with slightly lower water content, the sputum can be shorter, which is more conducive to full fermentation and compaction seal.
You can choose different types of mowers depending on the amount of cattle and the amount of silage processed, or you can buy the crushed corn stalks directly.
In addition, it is worth noting that the feed may be mixed with iron products. If the wire enters the rumen of the cow, it should be checked in time with the cattle stomach magnet test digestive system .
The silage should be compacted by the side of the pool. It can be repeatedly crushed by a tractor. Generally, it should be crushed once with a tractor by filling 30~50 cm thick.
After filling, it must be sealed with plastic cloth and covered with soil to prevent air from entering the fermentation.
In an environment of internal hypoxia, lactic acid bacteria will ferment and decompose sugars. The carbon dioxide produced in this process will further exclude air.
The secreted lactic acid can make the feed weakly acidic and inhibit the growth of other bacteria.
When the lactic acid bacteria are also inhibited by the lactic acid secreted by itself, the fermentation stops.
The feed will enter a stable storage stage, and it will not be a problem if it is stored for one or two years without opening it.
Prevent silage rot at the bottom
The 30~50 cm thick silage at the bottom is particularly prone to rot. In fact, the reason is very simple. That is, the moisture in the bottom silage is too large.
During the long-term storage process, the moisture of the silage will slowly infiltrate, and in the end it will accumulate to the bottom of the sputum.
If the water content exceeds the standard, it will definitely be prone to rot. In fact, the solution is very simple.
First, 20 cm thick dry wheat straw or dry straw can be filled in the bottom of the crucible.
Secondly, a drain with a width of 20 cm and a depth of 20 cm can be repaired and a plastic tube can be placed at one end to the outside.
Thirdly, the bottom can be designed in a rugged pattern at both ends, and a plastic tube is placed at the lower end to draw water.
