It is false that cured hay is an important source of vitamin B for grass-fed livestock.

1. Normal temperature ventilation drying method

Normal temperature ventilation drying uses high-speed wind to quickly dry the moisture contained in semi-dried grass. It can be regarded as a supplementary process to drying hay. . Use an electric fan or hair dryer to dry haystacks or haystacks without heating.

It is suitable for use in places where the day and night relative humidity is lower than 75% and the temperature is higher than 15°C during forage harvesting. In particularly humid places, the air in the blower can be appropriately heated to increase the drying speed.

2. Low-temperature drying method

The low-temperature drying method uses heated air to dry the grass moisture. Place the newly harvested forage in a relatively closed drying room, stack it into haystacks or place it on a slotted grass rack. Blow dry hot air from the bottom, and use an exhaust fan to suck out the humid air from the upper part. After a certain period of time, that is, Can be made into green hay. Suitable for rainy and humid areas or seasons.

3. High-temperature rapid drying method

Cut the harvested fresh forage into short pieces and then dry it in a dryer at a temperature of 50 to 80°C for 5 to 30 minutes. Dehydrate quickly to reduce the moisture content of the forage to less than 17%, which is then prepared into green hay. The length of grass chopped depends on the needs of livestock and the type of drying unit. The length range is generally 3 to 15 cm.

Plants suitable for drying hay:

1. Mexican corn grass:

This grass not only contains sugar, but also contains crude fiber and crude fat. and crude protein components. These components give Mexican corn grass a good taste. When grown as pasture, it can be harvested once every two months. When harvested, the fiber content is not high, and at the same time, it can retain the crisp and tender texture. Taste.

2. Sweet sorghum:

This kind of grass is a kind of grass with high sugar content. It not only contains sugar, but also contains many other nutrients. The fiber content is also very high, and the fresh-to-dry ratio after drying is considerable, making it more suitable for drying into pasture in winter.

3. Alfalfa:

This grass contains many nutrients, including crude protein and more than 20 kinds of amino acids, as well as other nutrients. Legumes have a high dry matter content, and the yield per mu is about 3,000 to 4,500 kilograms. After being dried into hay, the yield is about 1,000 kilograms. They are more suitable for drying hay.
