Eight technical points for making high-quality silage

The silage mainly maintains the nutrition of the green and juicy feed. It improves palatability. And people widely use it in animal husbandry production. Silage has become an important measure to adjust the seasonal surplus of green feed and improve the value of feed. Many areas are now developing aquaculture. In order to effectively save costs, farmers usually make silage by themselves. The following introduces you to eight technical points when making high-quality silage, which can help you produce high-quality silage.

Check and repair the silage facilities and processing equipment in advance.

Before making high-quality silage, you need to carefully check the sealing condition of the silage facility. If there is damage, repair it in time. It aims to avoid silage failure due to air leakage after storage. At the same time, it is necessary to carefully overhaul and debug the safe operation of the silage raw material processing equipment such as silage baler machines and chaff cutters. Fill the transmission parts with lubricating oil in time. Polish or replace the blade of the haymaker. Tighten the loose screws to avoid safety accidents or affect the silage process due to the “ill” operation of the processing equipment.

Choose high-quality silage raw materials

High-quality silage raw materials are the basis for making high-quality silage. Therefore, when selecting crop stalks such as corn stalks and sweet potato vines, it is necessary to harvest as much as possible in the best harvest period while ensuring the yield of grain. This can reduce the loss of various nutrients in the silage raw materials. If possible, it is best to plant high-quality pastures such as sorghum hybrid sudangrass and silage corn to produce high-quality silage raw materials.

Make high-quality silage in fine weather

When making silage, avoid rainy weather as much as possible. Rainy weather is not conducive to the orderly development of the harvest, processing, and suppression of silage raw materials. Thus, you cannot make high-quality silage.

Keep the environment and raw materials clean and hygienic

Cleaned up the transport vehicles, processing sites, and silage-making machine. Remove dirt, gravel, and other debris from the silage raw materials.

Ensure proper moisture of silage raw materials

In order to ensure the success of silage, the moisture content of silage raw materials should be controlled at 65% to 70%. If the water content is too low, the silage is easy to dry and mildew; and if the water content is too high, it will aggravate the loss of sugar in the raw materials. This is not conducive to the reproduction of lactic acid bacteria, and silage is also difficult to succeed.

A simple method for determining the moisture content of silage materials: take a handful of silage and hold it firmly in your hand. If there are small water droplets between your fingers, it means that the moisture content is greater than 75%; and if it is slightly damp, it means that the moisture content is between 65% and 75%; if not, moisture signs indicate that the moisture content is less than 65%. Therefore, when the water content is too small, an appropriate amount of water can be added to the chopped silage raw materials; and when the water content is high, it can be properly dried.

The chopped length should be appropriate when making high-quality silage

The chopped length of silage is preferably 1.5~2.5cm. Too long is not conducive to the compaction of silage. If it is too short, it will affect rumen digestion in cattle and sheep.

But if you use a professional chaff cutter and Straw crushing and recycling machine, it can solve the problem very well. That is because they can adjust the cutting length when they are working.

The professional straw crushing and recycling machine can not only collect silage materials quickly and efficiently but also can customize different versions according to your needs.

Maintain proper sugar content for silage raw materials when making high-quality silage

The storage quality of silage is related to the fermentation of lactic acid bacteria. So the growth of lactic acid bacteria requires a certain amount of sugar as nourishment, so the silage must contain a certain amount of sugar. Generally, not less than 1% to 1.5% of the weight of fresh raw materials. Corn stems and leaves, ears, and potato vines all contain enough sugar and are easy to silage. However, legume pastures such as alfalfa, potato sprouts, and peanut vines with low sugar content are not suitable for silage alone. You need to mix it with other high-sugar silages or add 5%-10% rice bran or wheat bran to increase the sugar content.

Strengthen post-storage management after making high-quality silage

After the silage is sealed, management should be strengthened. Prevent livestock and poultry, rats, insects, and birds from destroying it. If you find any damage, air leakage, or loose sealing, repair it in time to prevent the silage from being spoiled due to secondary fermentation.


The silage is charred and dried

Reason: The moisture is too low, the air is more retained, and the nutrient loss in the silage is greater.
Solution: Adjust the moisture content of the silage to 60-70% (hold the feed tightly with your hands, and only water seepage is the standard. For hard-textured raw materials, the moisture content can be appropriately increased, and vice versa.)

Silage smells bad

Reason: The silage moisture is too large (more than 80%), which causes the fermentation of butyric acid bacteria;
Solution: Remove too much water by drying, or add bran or hay to adjust.

The silage that has been successfully made is moldy.

Others are too slow to use, causing corruption while using it, or damage to the plastic film, causing air permeability, leading to corruption, etc.
Solution: timely use and seal up, and at the same time do a good job in the maintenance of silage to reduce damage and air leakage.

In addition, you can also try to add a straw starter to increase the fermentation bacteria, thereby improving the success rate and quality of silage.
