What is the classification of aquafeed? What is Extruded Feed?

Extruded feed is formed into a bulky and porous feeding bench through continuous mixing, quenching, heating and pressurization, maturation, extrusion of die holes and sudden pressure reduction in the high-temperature extrusion cavity through extrusion processing technology.

Advantages of extruded feed

1. Improve the utilization rate of feed Heat, humidity, pressure and various mechanical actions in the puffing process make the starch molecule 1, 4 - glycosidic bond break and generate low molecular weight products such as glucose, maltose, maltotriose and maltodextrin, and the extrusion processing can improve the gelatinization degree of starch, and the cell wall part of the fiber structure is destroyed and softened, and the digestible substances that are partially surrounded and combined are released.

2. Reduce pollution to the environment Puffed floating fish feed has good stability and performance in water. The feed pellets processed by extrusion extrusion are made by the starch gelatinization and protein structuring inside the feed and make the product have a certain bonding or binding force, and its stability is generally more than 12h, and the longest can reach 36h, so it can reduce the dissolution and precipitation loss of feed nutrients in water.

3. Reduce the occurrence of diseases Feed raw materials often contain harmful microorganisms, such as aerobic organisms, neutrophilic bacteria, Escherichia coli, molds, Salmonella, etc., and the content of animal feed raw materials is relatively large.

4. Better improve the storage stability of buty.

5. Feeding management is convenient, aquatic puffed feed can be suspended on the water surface (water) for a long time, and there is no need to set up a special feeding platform when feeding, only fixed-point feeding.

6. It can meet the needs of animals with different feeding habits Extruded feed can be divided into three types: floating, grinding, coarse, slow and rapid sedimentation, according to different processing techniques.

Adorned with oval fir to call the flute, buy the weft tip, restore the spine, and skid.

Good fish feed ingredients include: protein, fiber, fat, various vitamins and trace elements. Common fish feeds are divided into the following types:

Pelleted feed: is the most common fish feed. Generally, it is mostly floating. After the feed is put in, the pellet feed floats on the surface of the water, and the fish needs to swim to the surface and swallow it with their mouths open. The pellet feed does not sink, and it is not easy to leak into the crevices of the sand at the bottom of the aquarium, and spoilage.

Powdered feed: small grains that can be used to feed juvenile fish, and are commonly found in feed varieties of food fish. After the feed is put in, the powdered feed slowly sinks, and the fish can be forced to eat during the sinking process.

Generally, powdered feed for ornamental fish will puff up the powdered particles. so that it can be suspended in water for a longer period of time. The disadvantage of powdered feed is that it is easier to muddy the water.

Flake feed: also known as flake feed, it is the ideal feed form. After feeding, some of the flakes float on the surface, some are suspended in the water, and some are sunk to the bottom. However, due to the large surface area, it is not easy to leak into the bottom sand gap.

Patch feed: You can stick patch feed on the glass of the aquarium, and the fish will take the initiative to come and grab it. Patch feed is generally used as a supplement to other feeds.

Looking for fish feed, it is recommended to go to the China feed ** network to take a look, there are various fish series of fish feed.

Summary. Similarities: 1) All need to be nutritionally comprehensive, which fully meets the nutritional needs of animals;

2) It is required that the fat is not oxidized, does not contain aflatoxins, does not contain pathogenic bacteria, and the number of bacteria in the mold is controlled within a certain range; Heavy metals must meet the standards;

3) In terms of physical indicators, it is required that there is no mildew and deterioration, no agglomeration, peculiar smell and odor, the color and size are consistent, and the mixing uniformity is not more than 10%.

Differences: 1) The granularity of raw material crushing is different;

2) water stability is different;

3) There are differences in the shape of the feed;

4) Different requirements for the composition of feed nutrients: there are differences in the requirements for protein, nitrogen-free extracts, EFA, vitamins, minerals, etc.

The differences and similarities between aquatic puffed material and livestock and poultry feed.

Similarities: 1) All need to be nutritionally comprehensive, which fully meets the nutritional needs of raising Nianhuai animals; 2) It is required that the fat is not crude oxidized, does not contain aflatoxin, does not contain pathogenic bacteria, and the number of bacteria in mold is controlled within a certain range; Heavy high-town metals must meet the standards; 3) In terms of physical indicators, it is required that there is no mildew and deterioration, no agglomeration, peculiar smell and odor, the color and size are consistent, and the mixing uniformity is not more than 10%. Differences:

1) The crushing particle size of raw materials is different; 2) water stability is different; 3) There are differences in the shape of the feed; 4) Different requirements for the composition of feed nutrients: there are differences in the requirements for protein, nitrogen-free extracts, EFA, vitamins, minerals, etc.

What are the differences between aquatic extruded material and livestock and poultry feed in production management? What are the similarities?

Is there any other difference?

Gone, oh. Good.
