To make fish feed, it doesn t matter if the size of the crushed particles is there!

The particle size of ordinary fish feed fish feed raw materials is below 40 mesh, and the digestion and absorption rate is greatly reduced. The crushing particle size of carp, grass, green and bream juvenile compound feed should be over 50 mesh 60 mesh (, and the crushing particle size of adult compound feed should be through 30 40 mesh sieve. 60~。

Aquatic feed needs a finer particle size: aquatic products have different requirements for feed than terrestrial livestock and poultry, and the crushing particle size of aquatic feed is often finer than that of livestock and poultry feed, mainly for the following reasons:

1.Digestive capacity. The digestive tract of fish and shrimp is short and thin, and the ratio of its length to its own body length is generally much smaller than that of livestock and poultry, and its digestion and absorption capacity is also weak.

At present, most of the artificially cultured fish, shrimp and crab species are carnivorous or carnivorous omnivorous aquatic products, and their digestive tract length is shorter than that of herbivorous or filter-feeding. In addition, fish and shrimp have a weaker ability to digest and absorb plant-based grains or cakes, and even less able to use raw (unripe) feeds. Therefore, crushing the feed finely helps to improve the utilization rate of the feed.

2.Feeding environment. Aquatic animals feed in the water, and the feed must be put into the water.

Therefore, it is required that the aquatic feed should have a certain stability in the water to maintain its shape and nutrients from being lost. The smaller size of the pulverization helps to improve the water stability of the feed. At present, the common forms of aquafeed are hard particles, puffed particles, soft particles and dough feed.

For the first two forms, there is a hydrothermal quenching and tempering extrusion treatment in the processing process. The particle size is small, water and heat are easy to transfer to the inside of the powder particles, reduce the difference in the treatment degree of the particle center and the surface, and are conducive to the starch gelatinization and protein denaturation in the feed ingredients. The degree of variation is large, which can significantly improve the water stability of the feed.

For the latter two forms, the finer powder particles bond better with cohesive substances such as starch under the action of moisture, and the surface of soft particles or dough will also be smoother, which is conducive to improving the stability of feed water. In addition, when grinding with a finer particle size, the powder particles are also embedded with each other, which is also beneficial to the stability of the water.

3.Individual size. The individual of aquaculture aquatic products is generally not as large as that of livestock and poultry, and its caliber is also small. For the same aquatic species, the long product is thousands of times larger than the individual seed. Especially for fish, shrimp and crab fry, the particle size that needs to be crushed is correspondingly smaller.

There is a relationship, fish feed is generally 4 mm on it, this pay attention to look at the mold of the feed pellet machine, but the type of rain fed is different, and the feed eaten is not the same, very particular, learn more hi

Yes Big fish use big fish and small fish use small ones.

Fish feed pellets are processed from the crushed products of corn, soybean meal, straw, grass, rice husks, etc., which are directly pressed into the pellets.

Fish pellets have the advantages of comprehensive nutrition, strong stability, not easy to collapse in water, not easy to pollute the water body, easy to digest and absorb, and farmers save labor and labor, etc., and are favored by the majority of aquaculture farmers.

Classification according to processing methods and physical properties of finished products.

1.Soft pellet feed.

Features: moisture content 25-30%, density 1g cm3, soft texture, poor water stability Applicable: green, grass, bighead carp, crucian carp, tuantou bream.

2.Hard pellet feed.

Features: moisture content <12%, density, fine structure, good water stability, insoluble nutrients Applicable: carp, salmon trout, catfish.

3.Extruded feed.

Features: moisture content 6%, density < 1g cm3, loose structure, firm granulation, foaming particles Suitable for: ornamental fish, grass carp and other upper fish.

The raw materials of fish pellet feed include: silkworm pupa meal, rapeseed meal, soybean meal, cotton meal, corn, rice bran, bran, grass meal, additives, fish meal, sesame cake, feather meal, secondary meal, peanut meal, etc.

Reasons:1During quenching, the side potato is short and the quenching temperature is low, resulting in insufficient quenching and tempering, low temperature, insufficient maturity and insufficient moisture.

2.The content of bonding raw materials such as starch is insufficient.

3.The compression of the ring die is lower than that of the hand leakage. In general, under the premise of the transportation and proportioning of feed raw materials, the larger the compression ratio of the ring die pore size, the longer the water resistance of feed pellets.

4.Too high in fat or too much crude fiber.

5.The fineness of the crushing is not enough. The particle stability is poor due to the oversize of the raw material, and excessive crushing will increase the production cost. Fish feed, in particular, requires strict crushing particle sizes.

6.The composition and proportion of raw materials, the composition and proportion of raw materials have a great impact on the water resistance of feed. The larger the proportion of some feed ingredients in the feed formulation, the better the water resistance of the feed.

In production, lightly broken starch is often used to improve the water resistance of feed pellets, which can also be improved by adding binders.

Summary. Dear, it is a pleasure to serve you, the result of your query is: fish pellet material and refers to the recipe.

Fish pellet feed is a kind of fish pellet feed commonly used to feed fresh water fish, it has rich nutrition, clear taste, easy digestion and absorption, can meet the nutritional needs of fresh water fish, very popular. It contains cod liver oil, vitamins, fish meal, and other beneficial ingredients that provide a variety of substances in the water body. Fish pellets are a specially formulated fish pellet that is based on its traditional fish pellets with meat feed formulations similar to short-chain hydrolysis, as well as cereals, for greater functionality.

The addition of grains can provide more plant protein and a variety of fiber needed by aquatic weed fish, making it stronger and conducive to improving its intestinal digestion, while the multivitamins and antioxidants added to the product can effectively increase the immunity of fish food and reduce morbidity.

I bought fish pellets, but the manufacturer sent me pellets, and the manufacturer said that it was just a matter of size, and it didn't affect the ingredients, right?

Pro, from the theory of balanced matching fingers, it is true that it is only a small difference in the big selling posture, and does not affect the composition of the substance, but according to the actual situation, the composition and proportion of the specific substances they contain are not affected, and may also change some of the use effects, such as the buoyancy of particles of different sizes, etc. It is strongly recommended that you send the fish pellets back to the manufacturer for testing, or you can contact the manufacturer to ask for a sample to be tested in your own environment, and the test results can provide you with information to help you decide whether to use it.

Summary. Hello, I am glad to answer for you, the pellets are not so hard in this way: if the pellets are too hard, the pellet composition can be changed to reduce the hardness.

You can add fats, but you should control the amount, adding too much fat will cause the hardness to decrease, and it will become particularly brittle, or add some starch, or reduce the addition of fibers, these are all ways to reduce the hardness of granules. At the same time, temperature also has an effect on hardness.

Hello, I am happy to answer for you, the pellets are not so hard in this way: if the pellets are too hard, you can change the composition of the pellet wheel to reduce the hardness. You can add fats, but to control the dosage, adding too much positive burning fats will cause the hardness to decrease, and it will become particularly brittle, or add some starch and other lifting voids, or reduce the addition of fibers, these are all ways to reduce the hardness of granules.

At the same time, temperature also has an effect on hardness.

If you make a feed like a feed, it will disperse as soon as it enters the water, what is the reason for this?

Shrimp, feed. Reason analysis: after the aquatic pellet feed is soaked in water for a period of time, the pellets are easy to dissolve and disperse, because some feed is not eaten by fish and shrimp in time, which will cause waste.

Solution: We can add our Q702 nano-level materials to the formula of aquatic granules to reduce the loss rate of feed after entering the water, thereby reducing the waste of feed, not only that, adding Q702 aquatic feed, but also improve the nucleation, anti-compaction, grain toughness, refreshingness and grinding properties of aquatic feed.

1. Feed selection: There are many types of fish, and different types of food are different, so the feed selected is also different. If it is a carnivorous fish, it can generally only be fed with small fish, shrimp or invertebrates, and if it is an omnivorous fish, it is mainly fed with fish insects and aquatic plants, etc., and can also be fed with some frank grains.

2. Feeding frequency: Fish must pay attention to the frequency of feeding, in order to ensure the growth of the fish, feed it every day, usually two to three times, do not feed too much each time, so as not to eat a large number of drafts and discharge, resulting in the deterioration of the water body, thereby affecting its health, and even causing it to get sick.

3. Precautions: The time to feed the fish is generally in the white sky, from 9 o'clock in the morning, until before 4 o'clock in the afternoon, in winter, you can search and shorten the period, from 10 o'clock in the morning to 3 o'clock in the afternoon, because the temperature at this time is suitable for the bend of the blind, the fish's appetite is strong, and the feeding is relatively fast.
