Silage is a roughage obtained by chopping greenish feed with a water content of 65%-75% and then inhibiting the propagation of various bacteria by fermentation of anaerobic lactic acid bacteria under closed and anoxic conditions. The silage smell is sour, soft and juicy, good palatability, nutrient-rich, and conducive to long-term preservation. It is an excellent source of feed for livestock. The silage process is mainly a variety of microbial fermentation processes, mainly lactic acid bacteria fermentation to produce lactic acid, reducing the pH value of silage, lactic acid itself is both nutrients, and inhibit the growth of other microorganisms (such as spoilage microorganisms) in the feed, so that the feed Can be preserved for a long time. Known as the "king of pastures", it is not only high in yield, but also excellent in grass quality, and all kinds of livestock and poultry are fond of eating. It is the most common method for feeding livestock and poultry. It has silage or semi-dry silage, has low nutrient loss, has the nutritional characteristics of green and green feed, has good palatability, high digestibility and long-term preservation. At present, developed animal husbandry Most of the hay-focused modulation methods have changed to silage utilization. The following silage methods are mainly used. First, semi-dry silage In foreign countries, silage towers are generally used for semi-dry silage preservation. The silage towers are expensive. China generally uses silo kiln storage rafts. No matter which method is adopted, the key is to quickly dry the rafts to reduce the water content to 40%-50%. Silage. This silage combines the advantages of hay and silage. Second, the formic acid silage This is a method of promotion in foreign countries in recent years. The method is to add 2.8kg-3kg of 85%-90% formic acid per ton of silage material, and spray it in layers. Formic acid can be decomposed into CO2 and CH4 which are not toxic to livestock during silage and rumen digestion, and formic acid itself can be absorbed and utilized by livestock. The silage is used to feed dairy calves with an average daily gain of 0.757kg. -0.817kg, which is nearly double the weight gain of ordinary silage. Third, stretch film silage technology This is a new method adopted in foreign countries in recent years, all mechanized. The operating procedure is: mowing the grass - baling - baling - winding the stretch film. Its advantages are mainly not affected by weather changes, long storage time, generally can be stored for 3 years to 5 years, easy to use.
