Cattle Feed Pellet Introduction
Cattle feed pellet is a type of compound feed mainly made from barley, forage, bean, bran, wheat, corn and additives, such as, vitamins, minerals, and other essential micro-ingredients. Pelleting allows the use of a wider variety of ingredients without obvious changes in the physical properties of the diet. It is simply put the feed in a concentrated form. The pellets are very nutritional and can satisfy the growth needs of cattle in different growth stages. By combining moisture, heat and pressure on feed ingredients, a degree of gelatinization is produced, which allows cattle to better utilize the nutrients in these ingredients. The feed pellets are widely used in small-sized farms and large-medium feed factories.

Raw Material Receiving
The raw materials for cattle feed pellets can be corn, barley, wheat, soybean, cotton stalk, corn fiber, grass, maize straw, soybean meal, cereals, molasses, and so on.
The grinding process is provided at the pellet plant to grind the materials into powder form. Grinding is the most effective processing technique to improve nutrient utilization and animal performance. Uniform particle size ensures better quality of final pellets. The grinding increases surface area of ingredients for improved rate of digestion and decreased segregation.
Batching is considered to be one of the most critical and essential operations in feed pellets manufacturing. Proper batching can improve diet uniformity and animal performance. Batching the powder feed raw materials according to the formula.
This process is used for mixing the crushed raw materials with higher uniformity. The mixing process determines, to a high degree, the capacity of the whole manufacturing process and the quality of the final product.
The main purpose of this operation is to convert mash feed into pellet form by mixing with steam. The mash feed is fed from the storage bin to the feeder, and thereafter to the conditioner, where dry saturated steam is mixed with the feed, and then fed to the pellet mill at a controlled rate. After pelletizing, the palatability and digestibility of feed is largely improved.
The newly pressed pellets are very high in temperature. They must be cooled to avoid formation of lumps and deterioration of feed quality. The feed pellets are cooled in the pellet cooler by induced cool air draft. This process is to cool the pellets to ±3-5℃ of the room temperature.
Cooled pellets are carried to the pellet sieve by an elevator. In the pellet sieve, crumbled pellets and powder materials are separated from the good pellets and sent to the pellet mill for re-pelletizing while good pellets are stored into the bagging bin.
This process is to pack the feed pellets into bags which are convenient for storage and transportation. The bagging operation is semi-automatic. The bags are fixed manually and the filling is done automatically.

Benefits of Feed Pellets for Cattle Farming
* Decreased feed wastage during the eating process.
* Improved palatability and digestibility.
* Decreased ingredient segregation.
* Reduced opportunities for selective feeding
* Easy to ship, store and handle.
* A better flow and handling characteristic, particularly important to dairy farmers.

In cattle feed pelletizing, the most important is of course the feed pellet quality. The factors that influence pellet quality can be divided into several categories.
It is generally agreed that the formulation is, by far, the most important factor affecting pellet quality. Formulation is based on meeting the nutrient requirements of the cattle at the least possible cost. Take the variety, weight, age, feeding condition, feeding mode into consideration when design the formulation.
Conditioning is the most critical step to manufacture quality pellets. The high conditioning temperature can fully gelatinize the starch and improve the binding properties of feed pellet. More and more feed manufactures adopt the steam jacket conditioner to increase the conditioning temperature.
Grinding has a considerable impact on pellet quality (20%). Generally, the finer particle, the better feed pellet quality. When conditioning, finer particle has more contact area with water steam, thus increasing the starch gelatinization degree and digestibility. Also the finer particle can ensure the better surface quality of pellets.
The die is still responsible for 15 per cent in the quality of the feed pellet. Different feed pellets require different compression ratio of ring die. So feed producers adopt corresponding ring die specification to ensure the feed pellet quality when making feed pellets for cattle in different stages.
After leaving the pellet mill, the pellets have a temperature of 70-90℃ and the moisture of 15-17%. Proper cooling is required to lower pellet temperature to about 3-5℃ above the ambient temperature, and moisture to be 12%.
