In times of global uncertainty in agriculture, the compound feed industry is under pressure. Export restrictions, climate change, and geopolitical tensions affect the availability and cost of animal feed. Rather than relying solely on protein sources like soy, it is important to consider alternative protein supplies, such as nutrient-rich alfalfa, meadow grass, and clover grass. But how can these feedstuffs be turned into a genuine source of protein that is available all year round?
The global grain supply faces growing challenges. Markets are characterized by uncertainty, leading to higher and more fluctuating prices. Problems arise, in particular, when using soy as a protein source for feed. It is ecologically controversial, often genetically modified, and transported long distances around the globe. This is all at odds with sustainable, future-oriented agriculture.
Fiber-rich grasses such as meadow grass and clover grass, as well as alfalfa and herbs used as supplementary feed, contain plenty of protein, vitamins, and minerals that promote balanced animal nutrition and, consequently, animal health. These grasses are a sustainable solution for the compound feed industry, especially in regions where they are readily available. Innovative processing methods make these feed sources accessible worldwide, even in places where cultivating roughage is limited.
From the meadow to pellets
In cattle farming, the diet is based on grass and corn silage, as well as hay and straw. However, there is not enough grassland to meet the demand for roughage everywhere. In such cases, feed must be purchased. Pelletization ensures that these feedstuffs can be stored for long periods and transported economically. After harvesting, the grass or alfalfa is dried, chopped, and formed into pellets in a pellet mill using a die. Finally, the pellets are gently dried with hot air. Converting them into pellets is the ideal way to preserve this nutrient-rich feed for winter without losing important nutrients. This is because the gentle process preserves most of the natural nutrient composition. Pelleting with gentle drying significantly reduces the volume of green forage with minimal loss of nutrients. Pellets turn green forage into a real delicacy for many farm animals. The natural sugars caramelize during the process, giving the pellets a slightly sweet flavor that many animals find particularly tasty.
Advantages at a glance
- Space-saving and easy to transport: Pelleting reduces the volume of green forage while increasing the bulk density to over 650 kilograms per ton. This allows large quantities to be transported and stored efficiently.
- No room for pests: Fungi and other pests don't stand a chance due to the low water content in the pellets.
- Consistent feed quality: Whether summer or winter, pelleting ensures that the feed remains of high quality throughout the year. Compared to silage and hay, pellets offer greater nutrient stability.
Efficient technology for feeding in agriculture
The advantages of pelleted green forage are obvious. But how can it all be implemented efficiently in practice? Our pellet mill 55-1500 was specially developed for processing grass, alfalfa, and other similar materials, and it impresses with its high performance. With a die diameter of 1,500 millimeters and a perforated area around 50% larger than that of its predecessor, it is extremely powerful without requiring additional space. Grass and other biogenic fiber products, such as corn, hay, and straw, can be processed without pre-crushing, making the process even more efficient.
In agriculture, products that are rich in crude fiber are characterized by a significantly higher volume and a very low weight. This combination allows the pellet mill to be driven by just one motor. This reduces energy consumption, maintenance costs, and lubricant use for feed producers.
We understand that different animal species have different needs and that their requirements for feed vary accordingly. That is why the flat die pellet mill is designed to be easily adjustable. The die hole diameters vary between 6 and 18 millimeters, so it can be used for cattle, camels, horses, and small ruminants such as sheep or goats. Special solutions, such as cloverleaf shapes, are even possible.
The future of animal feed
Alfalfa, grass, and other plants have established themselves as valuable resources and, in the form of pellets, offer an efficient and sustainable feed solution. They are more than just a source of protein: as an alternative to soy, they make livestock farmers less dependent on price fluctuations and trade barriers.
Green forage is not only “green,” but it is also becoming a real “superfeed” for cattle, pigs, camels, and other animals. Thanks to innovative technology, it has a long shelf life in the form of compact pellets and can be easily transported and stored in a space-saving manner. A win-win situation for animals, farmers, and the environment.
