The benefit of using green hay to raise donkeys is good

Hay is a very nutritious feed for raising donkeys. How to make artificial drying of green fodder? please explain it to everyone today: artificial drying is the use of heating and ventilation to prepare hay. The drying time is short, the nutrient loss is small, and the high quality hay can be prepared. There are room temperature, low temperature and high temperature drying methods.

The normal temperature ventilation drying method uses the high speed wind force of the general fan or heating fan to dry the grass in the grass storehouse: the low temperature method can use the temperature of 45 to 50 ℃ to stay in the small room for several hours to make the grass dry: the meat donkey high temperature method uses 500 to 1000 ℃ of hot air to dehydrate for 6 seconds. In addition, there is a simple and easy method of artificial drying, that is, the application of chemical agents. The chemical agents commonly used are also called desiccants, such as formic acid and silicic acid. The prepared high-quality hay should be green in color, fragrant in smell, complete in plant and high in leaf volume, less sediment, no impurities, no mildew and deterioration, and the water content is less than 15%. High-quality green hay can be cut short and mixed with concentrate feed to feed donkeys, and can also be used to produce pellet feed. Roughage refers to the meat donkey breeding feed with crude fiber content of more than 18% in dry matter, including hay, straw, blighted shell and so on. 1. The content of crude fiber is low and the digestibility is low. The crude fiber content of meat donkey roughage is generally 25% 50%, and the content of hay is less, 25% 30%. Crude fiber contains more lignin, which is difficult to digest and poor palatability. The digestibility of organic matter in roughage is less than 70%. 2. There is a great difference in protein content and poor quality in roughage. The price of donkey is 10%-19% crude protein in leguminous hay, 6%-10% in gramineous hay, and only 3%-5% in gramineous straw and blighted shell. The crude protein in straw and blighted shell is difficult to be digested by donkeys. 3. High calcium content and low phosphorus content. The calcium content of legume hay and straw in meat donkey farming is about 1.5%, while that of Gramineae hay and straw is only 0.2% and 0.4%. 4. It is rich in vitamin d and less in other vitamins. High-quality hay for raising donkeys contains more carotene, especially legume hay after sun exposure, which contains a lot of vitamin d, and almost no carotene and vitamin b in all kinds of straw and blighted shell.
