How to make silage

The silage silage is a kind of roughage obtained by crushing the green crickets with a moisture content of 60% to 65% and then inhibiting the propagation of various bacteria under the condition of tight anoxic conditions by anaerobic lactic acid bacteria fermentation.苜蓿 Silage is a good source of feed for livestock, because it is sour, soft and juicy, good palatability, rich in nutrients, and conducive to long-term preservation.

The process of silage is mainly a process of fermentation of various microorganisms, mainly lactic acid bacteria produce lactic acid, reduce the pH value of the silage, lactic acid itself is not only nutrients, but also has the effect of inhibiting the growth of other microorganisms in the feed (such as spoilage microorganisms), so that the feed Long-term preservation.

Known as the "King of the pasture," it not only produces high yields, but also has excellent grass quality. All kinds of livestock and poultry eat well. At present, most of the developed countries in the livestock husbandry have adopted the modulation of hay as the focus of modulation and utilization of silage, and have turned to silage utilization. The following types of silage are mainly used.

First, the conventional single silage method

The conventional silage method is to dry the crop after drying for 1 to 2 days, so that the moisture content is reduced from 80% to 60% to 65%, and the pulverization is performed. The silage is filled in the silo, and the pulverization must be finer and finer than the silage corn straw. Degree requirements 1 ~ 2cm, so as to facilitate compaction, discharge air, to ensure the quality of silage silage. If a certain amount of lactic acid bacteria is added during the silage process, the amount added per ton is about 50 to 100 grams, and the silage effect will be better.

Second, mixed silage method

The mixed silage method is to add feedstuffs such as straw powder, bran, corn flour, etc., to the fresh alfalfa containing 80% of water content, so that the moisture content is adjusted to 60% to 65%, and it is best to mix first. The smashing is then performed so that the smashing is easier, the mixing process is reduced, and labor costs are saved.

Third, semi-dry silage

In foreign countries, silage towers are used for semi-dry silage preservation. The cost of silage towers is relatively high. In China, silage storage tanks are generally used. No matter which method is used, the key is to first make the pods quickly dry to reduce the water content to 40% to 50%. Silage. This silage combines the advantages of hay and silage.

Fourth, add silage formic acid

This is a method popularized abroad in recent years. The method is to add 85% to 90% formic acid of 2.8kg to 3kg per ton of silage raw material, and spray in layers. Formic acid in silage and rumen digestion can be decomposed into CO2 and CH4 that are non-toxic to livestock, and formic acid itself can also be absorbed and used by domestic animals. This silage is used to feed dairy calves with an average daily gain of 0.757 kg. ~ 0.817kg, nearly 1 times higher than the normal silage weight gain.

Fifth, wrapping silage technology

Wrapped silage is a new method adopted at home and abroad in recent years, all of which are mechanized. The operating procedures are: mowing - baling - bale - wrapping a stretch film. Its advantages are mainly not affected by weather changes, long storage time, generally can be stored for 3 to 5 years, easy to use.
