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. The key is to minimize turning and handling during the drying process to reduce leaf loss and maintain quality.
2. **Rack Drying Method** – This method is commonly used in wet regions or during rainy seasons. Grass should be placed on racks in a conical or ridge-shaped pile, ensuring it remains fluffy and not too thick—no more than 80 cm. Proper airflow is essential, and the outer layer should be smooth with a slight slope to allow water runoff.
3. **Artificial Drying Method** – This involves using heat sources to control the drying process. Common techniques include normal temperature air drying, where a hay shelter is built and a blower is used to dry the grass; low-temperature drying, which uses a drying room equipped with a preheating unit and blower; and high-temperature rapid drying, where the grass is chopped and then dried using a specialized forage dryer.
**Hay Storage**
1. **Indoor Storage** – 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 maintains the quality of the hay.
2. **Outdoor Storage** – Choose a high, dry area for outdoor storage. The base should be raised at least 30–50 cm above the ground to avoid moisture absorption. When stacking, press the hay down as much as possible and cover it to protect it from rain and sunlight.
Proper harvesting, drying, and storage are crucial for maintaining the nutritional value and quality of hay, ensuring it remains a valuable feed source for livestock throughout the year.
