Leguminous forages are typically harvested from the bud stage to the early flowering period, while grasses are usually cut during the heading stage. K8h China Feed Industry Information Network - based on feed, serving animal husbandry.
**Hay Production**
1. **Field Drying Method**. Depending on local weather conditions, you can choose between flat drying, small pile drying, or a combination of both. Throughout the drying process, it's important to minimize turning and handling the grass to reduce leaf loss and maintain quality.
2. **Grass Frame Drying Method**. This technique is commonly used in wet regions or during rainy seasons. When drying grass on racks, arrange it in a conical or ridge shape, ensuring it’s loosely packed and not too thick—no more than 80 cm. Good airflow is essential, and the outer layer should be smooth with a slight slope to allow water to drain away.
3. **Artificial Drying Method**. This involves using heat sources to control the drying process. A common approach is normal temperature air drying, where a hay shelter is built and a blower is used to dry the grass. Another method is low-temperature drying, which uses a drying room equipped with an air preheater and blower. For faster results, high-temperature rapid drying is employed, where the grass is first chopped and then dried using a specialized forage dryer.
**Hay Storage**
1. **Indoor Stacking**. When storing hay indoors, make sure there is enough space between the hay and the roof to ensure proper ventilation and cooling. This helps prevent moisture buildup and reduces the risk of mold.
2. **Outdoor Stacking**. Choose a high, dry, and level area for outdoor storage. The base of the stack should be raised at least 30–50 cm above the ground to avoid moisture absorption from the soil. When stacking, press the hay down as much as possible, cover it properly, and protect it from rain to maintain its quality over time.
By following these methods, farmers can ensure that their hay remains nutritious, safe, and suitable for long-term use in livestock feeding. Proper drying and storage practices play a crucial role in preserving the value of forage crops.
