What is the process of making alfalfa pellets

Alfalfa pellets, a popular and nutritious animal feed, are made from alfalfa, a high-yielding perennial legume. These pellets serve as a valuable source of protein, fiber, and essential nutrients for livestock, particularly horses, cows, and rabbits. In this comprehensive guide, we’ll delve into the intricate process of producing alfalfa pellets, exploring the steps from field to bag.

Cultivating Alfalfa

The journey of an alfalfa pellet begins in the fields. Alfalfa cultivation is an essential step in the granulation production process. Farmers typically plant alfalfa seeds during the early spring or late summer, carefully selecting a fertile, well-drained soil. The alfalfa plants grow, reaching a height of around two to three feet and producing lush, green leaves. Once mature, the alfalfa plants are ready for harvesting.

Harvesting Alfalfa

The harvesting phase is crucial to ensure the quality of the alfalfa pellets. Farmers use specialized machinery, such as forage harvesters or swathers, to cut the alfalfa plants. The timing of the harvest is critical, as it affects the nutritional content of the crop. Most farmers aim to cut alfalfa when it’s in the late bud to early bloom stage, as this is when the plant contains the highest levels of nutrients and protein.

Drying the Alfalfa

After harvesting, the alfalfa must be dried to reduce its moisture content. Excessive moisture can lead to mold and spoilage during the pelletizing process. Alfalfa is typically spread out in the field to dry in the sun, a process known as wilting. In some cases, farmers may use mechanical hay dryers to speed up the drying process.

Baling the Alfalfa

Once the alfalfa has reached the desired moisture content, it’s baled into compact, manageable units. The baling process involves compressing the dried alfalfa into rectangular or cylindrical bales. These bales are then ready for transport to the pelletizing facility.

Processing Alfalfa Bales

At the alfalfa pellet mill, the bales undergo several steps to transform them into pellets. The key processes involved in this transformation include:

Grinding: The alfalfa bales are first ground into smaller particles, often resembling a coarse powder. This increases the surface area of the alfalfa and prepares it for the pelletizing machine.

Pelletizing: The ground alfalfa is fed into a pelletizing machine, where it’s compressed into dense, small cylinders. These cylinders are the alfalfa pellets themselves. A combination of heat and pressure is applied during the pelletizing process, which activates the natural lignin in the alfalfa. This lignin acts as a binding agent, holding the pellets together.

Cooling: The freshly formed alfalfa pellets are quite hot, so they are sent through a cooling system to bring down their temperature. This prevents any potential moisture buildup or condensation inside the storage bags.

Screening and Grading: The cooled alfalfa pellets go through a screening process to remove any fines or dust. This ensures that the final product is consistent in size and quality. The pellets are then graded according to size, and any subpar pellets are discarded.

Bagging and Storage

The finished alfalfa pellets are typically bagged in large sacks or containers for distribution. These bags are often sealed to maintain the quality and prevent moisture from entering. Some producers may also add a protective coating to enhance the pellets’ shelf life.


The production of alfalfa pellets is a meticulous process that involves careful cultivation, harvesting, drying, and processing of the alfalfa crop. The end result is a highly nutritious and convenient feed option for various animals, offering a rich source of protein, fiber, and essential nutrients. This journey from field to bag ensures that animals receive the best possible nutrition while allowing farmers to efficiently store and transport their alfalfa crop.
