pelleted feed vs extruded feed
pelleted feed and extruded feed both are common type of feeds when we feed our horse, chicken, cattle, pig, fish, and sheep etc. sometimes we will face a problem of selection, which type should I choose from pelleted feed vs extruded feed. and what is the difference between pelleted and extruded feed?
what is extruded feed?
Extrusion is the cooking of the ingredient mixture in an extruder through temperature, humidity and pressure. Moisture provides lubrication for compression and extrusion and causes some pasting of the raw starch on the ingredient surface at high temperatures, resulting in adhesion.
Within 20 seconds of entering puffing, the ingredients change from an air-dried (about 10-12% moisture) state at ambient temperature to 15-16% moisture at 80-90°C. During the subsequent compression and extrusion of the holes in the die, friction raises the feed temperature to nearly 92°C.
Extrusion is a process in which the food is not only compressed like pellets, but also “cooked”, that is why it requires higher moisture, higher temperature and higher pressure than pellets. When it leaves the extruder, all these requirements must be met to achieve the desired level of expansion. In addition, as mentioned above, the other advantages of extruded feed include lower contamination, longer stability in water and maintaining all its nutrients, higher digestibility, high efficiency and high conversion rate. Thus, extruded feed is a higher qualified feed which can improve the profitability of fish farms. check the list of fish feed mill equipment for making extruded feed.

what is pelleted feed?
Pelleted feed are made from mash, which is then heated and compressed into hard, dense pellets. pelleted feed are designed to be complete feeds with appropriate levels of protein, vitamins and minerals. Since the pelleted feed are larger and more difficult to digest, they are usually used in adult hens rather than young chicks or pellets.
Pelletizing is the process of compressing small particles into larger solids with a given shape and texture, which involves a combination of moisture, heat and pressure. These larger homogeneous particles, also called dense particles, is formed by the coalescence of small components, which can sink rapidly in water. The main factors affecting pelletizing are ingredient characteristics, moisturizing or steaming before pelletizing, die thickness and binder. check the list of feed mill machinery for making pelleted feed.

what is the difference between pelleted and extruded feed?
pellet feed and extruded feed has their own disadvantages and advatages when comparing pelleted feed vs extruded feed.
Extruded Feed: Extruded feeds may contain more fat than pelleted feeds because too much fat can cause the pellets to fall apart. Higher fat means higher calories, which is a benefit for many categories of horses, including hard feeders and performance horses with higher energy requirements. Horses that are not used to squeeze feeds may take a few days to become familiar with the lighter, more breathable texture. Other advantages of extruded feed include lower contamination, longer stability in water while maintaining all its nutrients, higher digestibility, higher efficiency and higher conversion rates.
Pelleted Feed: One of the main advantages of pelleted feed compared to extruded feed is the lower manufacturing cost; however, it has many disadvantages than extruded feed.
