These cobs consist of refined, hot air dried and pelleted meadow grass, clover grass and alfalfa, which comes from agricultural grassland and cropland and can be pressed to a diameter of 8 mm to 16 mm.
The complex natural compound of nutrients and the high beta carotene content make this product so valuable. The animal metabolism can convert the natural beta carotene particularly well which means that it is available to the animal in higher quantities. In addition, the cobs' dry matter contains other important components such as protein and amino acids. The high content of high-quality proteins and numerous vitamins and minerals make them an ideal feed, which contributes to the healthy nutrition of animals. Furthermore, the product offers a higher feed intake due to its good tastiness (caramelisation of the sugar content).
Pelleting of grass and alfalfa rich in fibres makes stable storage and economical transport possible. The pelleting process reduces the volume of the green forage and enables dry storage over a longer period of time. This process causes the least loss of nutrients of all known preservation methods. In addition, pelleting enables feeding with a high content of protein. Cobs are already an important protein component for organic farms. For quite some time there is a trend to use the KAHL flat die pellet mills for grass cobs, mainly for the production of special shapes in premium quality (cloverleaf, square, floral shape etc.).
Advantages of pelleting can also be found in the well-known KAHL technology. The KAHL press configuration has a specific advantage for all products with a high fibre content, including cobs made of grass or alfalfa. Thanks to the KAHL flat die pellet mills, no further pre-grinding is required for the chopped product. A simple integration into the drying plant makes it possible to pellet the product and sell it as valuable animal feed.
The comprehensive KAHL machine portfolio offers numerous possibilities to meet different requirements for the pelleting of grass, alfalfa, but also straw and hay. Over 140 years of experience and numerous installed plants show that we have the right solution for any requirement.
