How does Poultry Feed Extrusion work?
The process of poultry feed extrusion involves the use of a machine called an extruder. The extruder is a long, cylindrical device that contains a screw-like device called an auger. The auger is responsible for moving the feed mix through the extruder.
As the feed mix moves through the extruder, it is subjected to a series of heated metal plates. These plates heat the feed and cause it to expand. The expanded feed then passes through a die, which shapes it into pellets or flakes. The extruded feed is then cut to the desired size by blades.

How is Animal Feed Produced Using Extrusion?
Animal feed can be produced using extrusion in two ways: batch or continuous.
In batch extrusion, the feed mix is placed into the extruder and then the machine is turned on. The mix is heated and expanded as it passes through the extruder. Once it has been shaped into pellets or flakes, it is cut to the desired size and then removed from the machine.
In continuous extrusion, the feed mix is constantly being fed into the extruder. The mix is heated and expanded as it passes through the extruder, and then it is cut to the desired size by blades. This process allows for a high production volume.
Applications of Feed Extrusion
Feed extrusion can be used to create a variety of products for both animals and humans. Some common applications include:
- Cat food
- Dog food
- Fish food
- Bird food
- Zoo animal feed
- Aquaculture feed
- Horse feed
- Cattle
What Happens with the Anti-nutritional Factors During Extrusion?
Anti-nutritional factors are substances that can reduce the nutritional value of feed. They can also make feed less digestible for animals.
Some common anti-nutritional factors include tannins, phytic acid, trypsin inhibitors, and lectins.
During extrusion, the heat and pressure of the process can reduce the anti-nutritional factors in feed. This can improve the nutritional value of the feed and make it more digestible for animals.
Some feed ingredients, such as soybeans, contain high levels of anti-nutritional factors. Extrusion can be used to reduce the levels of these substances and improve the quality of the feed.
