extruded fish feed

Expanded feed is a fluffy and porous feed made by feeding powdered raw materials into the extruder, mixing, shearing, tempering, heating, pressurizing, sudden depressurization and expansion of the mold hole, granulation, and drying. According to the different living and feeding habits of aquaculture animals, it can be made into floating, slow sinking, and sinking expanded aquatic feed.

Benefits Of Extruded Feed

Good palatability and improved feed digestion and utilization rate: 

After the expansion treatment of feed raw materials, the fragrance and palatability increase, which can stimulate animal appetite. The long chain structure of organic substances such as protein and fat gradually changes into short chain structure, which helps digestion. At the same time, it can reduce the pollution of organic substances such as ammonia nitrogen in fish feces and feces on water quality and maintain good water quality.


Save feed and reduce water pollution: 

Expanded feed has good stability, is not easily soluble, and can be suspended on the water surface, making it convenient to observe the feeding situation of fish and timely understand the growth status of fish.


Improved feed hygiene quality and reduced disease risk: 

After high-temperature instantaneous treatment, harmful bacteria such as Escherichia coli, mold, and Salmonella in the feed are completely killed, reducing the probability of intestinal infections in breeding animals.


How to Feed Extruded Feed?

1. Determine the correct amount of extruded feed to give to your aquatic animals based on their size and feeding habits. Consult with a veterinarian or aquatic specialist if you are unsure.

2. There are a few ways to rehydrate extruded feed. One way is to soak it in water for a few minutes until it becomes soft and pliable. Another way is to sprinkle the feed directly into the water where your aquatic animals swim, allowing them to eat it as it sinks.

3. If you are using extruded feed as a regular part of your animal's diet, it is important to offer a varied diet to ensure they receive all of the nutrients they need.

4. Be mindful of how much feed you are offering your aquatic animals. Overfeeding can lead to water quality issues, so feed only what your animals will eat within a few minutes.

5. Store extruded feed in a cool, dry place away from direct sunlight to maintain its freshness and nutritional value. Avoid using expired feed or feed that has an off smell or appearance.

Extruded Feed FAQS

Q
What are the requirements for stability of extruded feed in water?
A

Aquatic animals are different from Terrestrial animal and need to feed in water. Moreover, different types of extruded feed require different stability in water. Ordinary carp fish require their pellet feed to be soaked in water for 5 minutes, with a dissolution rate of<10%. Shrimp is harvested by feeding in a holding manner, requiring the shrimp pellet feed to be soaked in water for 120 minutes with a dissolution rate of ≤ 12%.

Q
What are the factors that affect the expansion of extruded feed?
A

The ratio of raw materials, the starch and moisture content in the raw materials, the expansion temperature and pressure, and the speed of the expansion machine all affect the quality of the expansion, especially the starch and moisture content in the raw materials, as well as the expansion temperature. These factors should be comprehensively adjusted in order to produce high-quality extruded feed.

Q
How should I store extruded feed?
A

Store extruded feed in a cool, dry place away from direct sunlight to maintain its freshness and nutritional value.  Avoid using expired aquaculture feed or feed that has an off smell or appearance.
