Raising donkeys on green hay is cost-effective, and farmers would do well to give it a try

Green hay is a very nutritious feed for raising meat donkeys. How do you make green feed using the artificial drying method? Today let me explain: the artificial drying method uses heating and ventilation to cure hay. The drying time is short, nutrient loss is small, and high-quality green hay can be produced. There are normal-temperature, low-temperature and high-temperature drying methods.

The normal-temperature ventilation drying method uses the high-speed airflow of an ordinary fan or a heated fan inside a hay barn to dry forage grass: the low-temperature method can use a temperature of 45-50°C and leave the green grass in a small chamber for several hours to dry it: the meat donkey high-temperature method uses hot air at 500-1000°C to dehydrate for 6-10 seconds. In addition, there is another simple and easy artificial drying method, namely applying chemical agents. The chemical agents generally used are also called desiccants, and include formic acid and silicic acid, among others. Well-cured high-quality hay should be green in color, aromatic in smell, with intact plants, a high leaf ratio, little sand and mud, no impurities, no mildew or deterioration, and a moisture content below 15%. High-quality green hay can be cut short and mixed with concentrated feed to feed meat donkeys, and can also be used to produce pellet feed. Roughage refers to meat donkey breeding feed with a crude fiber content of more than 18% in the dry matter, including green hay, straw, chaff and so on. 1. Low crude fiber content and low digestibility. The crude fiber content of meat donkey roughage is generally 25%-50%, and green hay has less, at 25%-30%. Crude fiber contains more lignin, is very difficult to digest, and has poor palatability. The digestibility of organic matter in roughage by donkeys is below 70%. 2. The protein content in roughage varies greatly and is of poor quality. The crude protein of legume hay for meat donkey prices is 10%-19%, grass hay is 6%-10%, and grass straw and chaff are only 3%-5%. The crude protein in straw and chaff is very difficult for donkeys to digest. 3. High calcium content and low phosphorus content. The calcium content of legume hay and straw for meat donkey breeding is about 1.5%, while the calcium content of grass hay and straw is only 0.2%-0.4%. 4. Rich in vitamin D and relatively low in other vitamins. High-quality hay for raising donkeys contains more carotene, especially legume hay after sun-drying, which contains a large amount of vitamin D, while various straws and chaff contain almost no carotene or B vitamins.
