We are a company produces palm oil where we also produce a by-product, palm kernel meal (PKM). We sell this product to the farming industry in the form of pellets. In order not to make the product bulky and dusty, we use molasses to improve the quality of the pellets, however, the quality of the pellets that we produce is still not as we expected where the pellets are easily broken and not in the same size, and we still find a lot of dust. In our opinion, maybe because the molasses are too sticky so it will make the process of material mixing difficult. Dear Fenanza Team, please give some advice, is there any better feed adhesive for us to use? Thank you.

Dear Bapak Chandra,
Thank you very much for the question. Palm kernel meal (PKM) is a by-product of processing palm kernel. Palm kernel meal contains only 10% of water and 60% of nutrients contain cellulose, fat, and protein. Although palm kernel meal (PKM) has a lower protein content the quality is sufficient and suitable for animal feed especially for dairy cows. Palm kernel meal has high-fiber and oily so that it can significantly affect the performance of feed.
Molasses is a by-product of the cane or beet sugar which contains sugar and organic acids. Molasses is a thick brown liquid that can also be used as a feed adhesive or adhesive of raw material, but often have problems in the mixing process, especially with dry ingredients such as powder. This happens because the sticky texture of molasses causes the feed ingredients to stick and not mixed perfectly. Besides, the type of raw material used also determines the quality factor of the density and durability of feed.
Pellet itself is a form of feed that is compressed from the mixture concentrated or forage material to reduce the bulkiness of the feed. In the process of making pellets, there is a heating process with pressure and steaming called the conditioning process. This process aims to create gelatinization of the material so that adhesion occurs between the constituent particles so that pellets with good texture and hardness are obtained. In addition, the conditioning process also aims to make: (1) feed sterile, free of germs; (2) making starch from existing raw materials as adhesives; (3) the feed becomes softer and become easily digest; (4) creates the aroma of the feed which further stimulates the appetite of the livestock.
The use of raw materials without feed additives is not enough to get a good texture and feed density. However, raw materials that contain fiber and fat content such as PKM will complicate the gelatinization process. Therefore, it is necessary to have natural additives that help activate the adhesiveness of feed ingredients with moisture and without the gelatinization process, to become pellets with a solid but not hard texture.
If the adhesion of molasses is still not perfect as stated, then we recommend using Lignobond DD natural binder produced from the processing of selected softwood which has 10 times stronger adhesion than ordinary binders (wheat by-products, tapioca, and molasses). Lignobond DD with the composition of calcium lignosulphonate can dissolve 100% in the fiber material so that it is very appropriate as a pellet binder for livestock, fish, and shrimp, also applicable for high fiber feed (ruminant), as well as special feed with high fat content or as binder for raw materials like PKM. The content of binder compounds serves to bind the material particles to become more compact which has high durability, reduces dust and prevents segregation or breakage of pellets in finished feed, without causing the pellets to become hard.
For getting the right dose, it can be tested in advance with the range of adding Lignobond DD 1 - 5 kg per ton feed depend on the raw material used in the feed making. The recommended dose is the highest first, which is 5 kg to find out the minimum dose that can be used. Please do not hesitate to contact the Fenanza team, who is always supported by a team of experts from Borregaard-Norway, because we believe that using the right Lignobond DD will solve the pellet problem. Good luck! Regards (D/IHN).
