Some tips on meal feed for fish

 Here are some tips on meal feed for fish.

Cake meal is the residual part of oilseeds after extracting most of the oil, including soybean cake, peanut cake, cottonseed cake, rapeseed cake, sesame cake, sunflower cake, or meal. This kind of feed has high crude protein content and is the main protein source in fish feed. In recent years, it has been widely used to replace expensive fish meal in fish compound feed with good effect. However, this kind of feed generally has the following shortcomings: 1. Low methionine content, more phosphorus and less calcium, lack of carotene, etc. ②It contains some toxic substances, which affect its palatability and digestibility. ③ In the case of excessive heating, the protein will be denatured and the protein digestibility will decrease. For safety reasons, the following precautions should be taken when using cake meal in fish feed:

1. Because of the harmful substances such as antitrypsin, the raw soybean meal has poor palatability and low utilization rate of feed protein. It should be used after proper heat treatment (110℃, 3 minutes).

2. Cottonseed meal contains gossypol and other harmful substances. Note that the proportion of adult fish feed should be controlled below 30%, and the amount of cottonseed meal in parent fish feed should not exceed 5%. When the proportion in the adult fish feed exceeds 15%, it must be detoxified before use. There are many methods for detoxification of gossypol, such as cooking method, alkaline water soaking method, ferrous salt method, yeast fermentation method, etc. Among them, ferrous sulfate method is the most simple and thorough. The amount of ferrous sulfate added is generally the free gossypol in cottonseed cake. 5 times the content. Hope you can see the diesel engine fish feed pellet machine.

3. Rapeseed meal contains a series of toxins or anti-nutritional factors. In order to improve its use effect and avoid poisoning, it is generally used in limited quantities (the dosage should be controlled below 20%) and strengthened with matching (used in conjunction with fish meal and bean cake) or adding Lysine. When the dosage is large, it should be detoxified. At present, the method of burial or fermentation is generally adopted, and it can also be detoxified by soaking in organic solvents.

4. Peanut cake contains antitrypsin, so it should be heat-treated before use. Generally, the antitrypsin is controlled at about 120℃. Shelled peanut cake has low crude protein content, high crude fiber content and low feed value, so it is not suitable for carnivorous and omnivorous fish, and herbivorous fish are also limited in use.

5. Sunflower cake has good palatability, and the quality of shelled cake is comparable to that of soybean cake, and it is non-toxic. The content of calcium, phosphorus and vitamin B group is higher than that of soybean cake, so it is an excellent protein source in fish feed. However, the shelled sunflower cake contains a lot of lignin, which not only makes the crude fiber difficult to digest, but also reduces the digestibility of nutrients. Generally, the dosage should be small, and it should not be used as meat and miscellaneous fish feed.

Performance of poultry poisoning caused by excessive heavy metals

 The heavy metal elements polluting animal-derived feed products mainly include lead, arsenic, cadmium, chromium and mercury. Bone meal and meat and bone meal may often contain a large amount of lead, arsenic, cadmium and other elements; feather meal and leather protein meal may contain a large amount of lead and arsenic, in addition, leather protein meal often contains a high amount of chromium; fish meal and other aquatic products In addition to a large amount of lead, arsenic, cadmium and chromium, the organism may also contain a large amount of mercury.

1 Fluorine

Bone meal, meat and bone meal and other animal-derived feed products may contain a large amount of fluorine to varying degrees due to different origins and raw materials. Animals raised in natural fluorine-rich areas and industrial fluorine-contaminated areas can accumulate a large amount of fluorine in their bones. Products made from such animal raw materials must contain high fluorine content. Long-term and large-scale use of such products can cause chronic chronic diseases in livestock and poultry. So you can use the floating fish feed machine.

      2 nitrite

      According to foreign reports, sodium nitrite has been used as a preservative in the production of fishmeal. If the amount is too large, it can lead to nitrous acid poisoning in feeding animals, which may be transformed into dimethylnitrosamine, a carcinogen. Ji Zhenyang (2005), He Jin (2006) and other relevant experts reported that when toxic elements exceed the standard, there are the following toxic manifestations.

3 Chrome

① Combines with nucleic acid and nucleoprotein in animals, affecting the phosphorus content in tissues; ② Reduces the activity of amylase and prevents cysteinase oxidation; ③ Impairs the function of red blood cells to carry oxygen, causing lung cancer, especially lysis Chromium compounds, which are acid insoluble in water, are more dangerous.

4 Cadmium

①Reduce the weight gain and feed conversion rate of broilers; ②Cause anemia in pigs, cause sheep anemia and renal dysfunction; ③Cause sperm inactivation in male animals; , Humoral immunity has inhibitory effect, reducing animal immunity.

5 Arsenic

①Combined with the sulfur group of pyruvate oxidase, making the enzyme inactive, affecting the normal metabolism of cells, leading to cell death; ②Harming nerve cells, causing polyneuritis and central neurasthenia, paralyzing capillaries, and causing tissue nutritional disorders; ③ The International Agency for Research on Cancer announced that arsenic is a carcinogenic factor; ④ acute arsenic poisoning can make animals die in a short time;

6 lead

①In the early stage, the excitation and inhibition process of the cerebral cortex can be mildly disturbed, and in the later stage, serious disorder occurs, causing the dysfunction of the sympathetic and parasympathetic nervous systems; ②Interfering with hemoglobin synthesis; ③Causing intestinal paroxysmal spasm or paralysis; ④Causing interstitial nephritis , Kidney atrophy, reducing animal immunity; ⑤ It can enter the lactating young animals through milk, causing harmful effects; ⑥ It can enter the fetus through the placenta and endanger the fetus.

7 Fluorine

①Causes the reduction of egg production of poultry, the fertilization rate and hatching rate of breeding eggs; ②Causes the decline of immunity of farmed animals; Inhibits the activity of oxidase and dehydrogenase, affects metabolism, and causes animal weight loss and anemia; ③Causes bone nutrition Bad, skeletal fluorosis, joint stiffness, tooth coloring, enamel damage; ④ cause cardiovascular disease, gastric cancer, lung cancer, and even death.

Goldfish Tank Size Guide

Size does matter. Yes, the bigger the better. If you can afford a huge artificial pond in your backyard, the best is yet to come. For the rest of us, the aquarium is the best home for our goldfish.

Here are the parameters that determine the size of the tank you need:

The size and age of a goldfish

When you buy goldfish from a pet store, make sure they are young, so they too have a lifetime to grow. You can also start with a smaller aquarium. However, the obvious disadvantage is that you will need to upgrade to a larger tank as the goldfish continues to grow.

The potential size of a goldfish

There is a legend about the size of goldfish. Goldfish grow with the size of their environment. Indeed, if you put one goldfish in a tank and another goldfish in a pond, there will be far more goldfish in the pond than there are fish in the tank. However, this is not because goldfish grow in the environment. It’s because the environment, or the lack of an optimal environment, prevents the goldfish from growing. Therefore, you must take into account the potential size of the goldfish.

For example, a black Moorish goldfish can grow up to 6 inches naturally. Therefore, a 30 gallon /114 liter tank is best for keeping two goldfish. The average goldfish, however, can grow to more than a foot long. So you have to take that into account. The exact number of cylinder parameters may not be hard and fast, but many veteran goldfish enthusiasts believe that 4 times the potential size of the goldfish is the most appropriate length.

Types of goldfish and the number of goldfish

It goes without saying that the more goldfish you have, the bigger fish tanks you’ll need. Goldfish, on the other hand, can grow quite large over a period of years. So, don’t buy 7 goldfish on the first try. Be a miser.

Also, keep in mind that the thinner, ordinary goldfish grow larger than the round, fancy goldfish. Therefore, you will need a larger tank to keep regular goldfish.

Conclusion

After reading a truckload of information, you might not know, ‘So what size aquarium do I need?’ But if you still put a gun to my head and ask me the same question, I would suggest that if you want your goldfish to grow healthily, start with a 75-to 125-gallon tank. Keep the quantity to a minimum. Don’t keep all kinds of goldfish in an aquarium. Keep size to a maximum and quantity and variety to a minimum until you become more experienced.

The size of Common and Comet goldfish tank

For general goldfish and comet goldfish, we recommend tanks at least 4 feet long with a capacity of at least 30 gallons. Of course, this is the bigger the better! So more than that is also good.

If you plan to keep more than one goldfish in your tank, add 12 gallons for each additional fish.

Fancy goldfish tank size

For fancy goldfish, we recommend a tank at least 3 feet long and a capacity of at least 20 gallons.

If you plan to keep more than one goldfish in your tank, add 10 gallons for each additional goldfish.

Any questions about the goldfish, you can come to lima contact and leave your message.

Fish food production equipment,fish feed pellet

Most of the fish food sold on the market is produced through batch processing of fish food production equipment, which usually goes through multiple processes such as crushing, batching, mixing and processing, pelletizing and drying. The main machines and equipment for the production of fish food are.

1、Crushing machine: the raw materials for the production of fish food will be crushed machine.

2、Mixing machine: the crushed fish food raw materials will be added a certain proportion of water, additives, mixed evenly. 

3、 loading machine: the mixing of raw materials will be transported to the feed hopper of the twin-screw extruder.

Come to see the fish pellet making machine in Lima.

4、 twin-screw feed puffing machine: mixed raw materials in a high-temperature, high-pressure environment and twin-screw extrusion, extrusion through the feed mold, adjusted to the same size and length of feed particles.

5、Conveyor: the produced fish feed pellets are transported to the multi-layer drying equipment.

6、Multi-layer dryer: general oven, including electric oven, fuel oven, gas oven and steam oven, which can adjust the temperature by itself, used to dry the feed pellets to safe water content and increase the shelf life.

7、Spraying and seasoning line: including oil spraying machine and seasoning cylinder for spraying oil and food attractant, etc., mainly spraying oil on the surface of feed and removing burrs and burrs on the surface of fish feed pellets to make the surface of feed pellets smoother.

8、Cooling conveyor: reduce the temperature of the surface of drying feed pellets, promote the solidification of grease, and facilitate packaging.

9、Vibrating sieve: sieve the excess external scattering material and granule debris.

10、Packing machine: to pack and seal the made fish food.

Make more nutritious fish feed

Fish need the correct balance of protein, carbohydrates, fats, vitamins and minerals to grow and stay healthy. This type of feed is considered complete feed.

So do you know lima, which is popular in fish feed machines.

Protein is the most important part of building a fish school. During their growth stage, omnivorous fish such as tilapia and carp require 25-35% protein in their diet, while carnivorous fish require up to 45% protein to grow at an optimal level. Generally speaking, young fish (fry and fingerlings) need a protein-rich diet more than they are in their growth stages. Proteins are the basis of structures and enzymes in all living organisms. Protein is composed of amino acids, some of which are synthesized by the body of fish, while others must be obtained from food. These are called essential amino acids. Among the ten essential amino acids, methionine and lysine are usually limiting factors, and these need to be supplemented in some vegetable basic feeds. 

Lipids are fats, and they are high-energy molecules needed by fish in their diet. Fish oil is a common ingredient in fish feed. Fish oil is rich in two special types of fats, omega-3 and omega-6, which are good for human health. The amount of these healthy lipids in farmed fish depends on the feed used.

 

Carbohydrates are composed of starch and sugar. This ingredient in the feed is a cheap ingredient that can increase the energy value of the feed. Starch and sugar also help to combine feed into pellets. However, fish cannot digest and metabolize carbohydrates well, and most of this energy is lost.

 

Vitamins and minerals are necessary for fish health and growth. Vitamins are organic molecules that are important for development and immune system function, synthesized by plants or through manufacturing. Minerals are inorganic elements. These minerals are necessary for fish to synthesize its own body composition (bone), vitamins and cell structure. Some minerals are also involved in osmotic adjustment.

So come to see the animal feed production line in Lima. I think this will help you a lot.

 

Feed formulation for African catfish

 How to make fish food pellet? Get different formulation for different fish from Lima Pellet Machine. Why do we need fish feed formulation? If the fish farmer only feed a single type of food, it is neither complete nor balanced and does not supply all the nutrients a fish might need in its diet.

1.Feed formulation for Catfish
Maize 24%, bean cake or sunflower see 29%, benseed 19%, fish meal 24%, vitamins 1%, inorganic salt 1%, DCP 1%, antibiotic leftover 1%
2.Feed formulation for Tilapia Feed
Formulation 1 : Rice bran 45%, bean cake 35%, powdered silkworm pupae 10%, thorn powder 8%, bone powder 1.5%, salt 0.5%. The feed coefficient is 2.27.
Formulation 2 : Bean cake 35%, wheat bran 30%, fish meal 15%, barley flour 8.5%, corn flour 5%, edible leaf powder 5%, bone powder 1%, salt 0.5%. The feed coefficient is 2.5.
3.Feed Formulation for Carp Feed
Bean cake 50%, wheat bran 15%,rice bran 15%, fish meal 15%, vitamins 1%, inorganic salt 1%, antibiotic leftover 1%, adhesives 2%. The feed coefficient is 2.7. Maybe you will be interested in the fish food extruder.

4.Feed Formulation for Grass Carp Feed
Formulation 1 : Rice bran 40%, wheat bran 38%, bean cake 10%, fish meal 10%, yeast powder 2%. The feed coefficient is 1.9. If a part of the green fodder is added, the feed coefficient is 2.2.
Formulation 2: Corn flour 70%, fish meal 10%, bean cake powder 15%, wheat bran 15%, other material (based the total material metering) can be: sweet potato powder 12%, salt 0.5%, growth substance 2%, calcium hydrogen phosphate 2%. The feed coefficient is 4.8.
Formulation 3: Green hey powder 40%, cottonseed cake powder 30%, bean cake powder 10%, rapeseed meal 5%, powdered silkworm pupae 5%, fish meal 5%, barley powder 5%. The feed coefficient is 8.
The feed formulation can be adjusted according to local condition. Normally, two essential amino acids which are often supplemented in the feed are methionine and lysine. For the nursery stage (5–20 g), the protein level in formulated feeds is about 30–32 percent, this value decreases with increasing fish size, the lowest value (22–26 percent) occurring at a size of >500 g. Similarly, the lipid level of the diet changes with fish size appropriate to the requirement, which varies from 4–6 percent. Furthermore, calcium and phosphorus may be added to the diets. The diet is usually formulated from local ingredients such as fish meal, trash fish, soybean powder, soybean cake, rice bran, broken rice, cassava flour, bone meal etc.

And if you have other poultry like chicken, maybe you can see the chicken feed pellet machine.

Floating or sinking fish feed pellet

 Floating or sinking fish feed pellet? Whether to use floating or sinking pellets mainly depends on which type of fish species that you have.

Features of floating and sinking fish feed pellet 

Type of feed Sinking Floating / slow sinking
Advantages
1. Good water stability
2. Cheaper than floating pellets and so lower capital costs.
3. Terrific for fast-moving stream
4. Better for fish who live in bottom Best water stability
5. Many anti-nutritional factors removed with heat.
6. Environment-friendly
7. Easy monitoring the fish 

Disadvantages
1. Dry ingredients required; vitamins partially lost.
2. Generally higher FCR than the floating pellet.
3. Fish feeding can not be observed. Extruders are more expensive and so a high production cost.
4. Requires more skill in production.

The aquaculture industry is the fastest growing food production industry on the world in the last few years. After this, I must tell you that the fish feed pellet machine in lima is so popular.

It’s approximately 50% of all fish consumed by humans is from aquaculture. Understanding about the requirements and production of fish feed is essential to the development and sustainability of aquaculture as the industry has matured.
When fish are reared in high density indoor systems or confined in cages and cannot forage freely on natural foods or natural foods are absent or where natural foods only make a small contribution to nutrition. Nutrition plays a vital role in improving fish productivity. The farmer should use nutritionally complete feeds. Feed comprises the biggest cost in intensive fish farming. Feeds can be produced either by steam processing, producing compacted, pressure-pelleted (sinking) feeds; or by extrusion, which produces expanded floating or buoyant feeds. Maybe you can go to see the animal feed production line.

Fish Feeds Types

Floating Feed –This type of feed floats on water. In general, floating feeds offer numerous advantages over their sinking counterparts.
Sinking Feed – Sinking feeds are solid feed pellets that are submerged during application. They are more economical.

Processing Technology
Compressed pellet
Steam treated compressed pellet Extruded/Expanded pellet
Processing Equipment
Animal feed pellet mill or ring die pellet mill. Single screw fish feed extruder machine or twin screw fish feed extruder machine.
Which one is better? Floating or sinking fish feed pellet. Generally there is no nutritional difference between floating and sinking feed, whether to use floating or sinking pellets mainly depends on which type of fish species that you have.
Floating Fish Feed Pellet 
The floating fish feed pellet is usually used in larger underlings, food fish and broodfish. Floating on the surface of the water (usually maintaining integrity in the water for several hours), the fish must come up to the surface to eat. The farmer can observe their fish each day, which helps in monitoring their health and vigor. Also they can adjust the amount of feed per day and avoid wasted feed and pond pollution problems.
Sinking Fish Feed Pellet 
But for some ornamental fish like goldfish and koi, sinking fish feed pellet is better for them. Because goldfish being a greedy pet will usually dash and swim towards their food and during the commotion while grabbing the pellets, they will end up sucking air into their stomach as they gulp their meal. Usually what you can observe is that air pockets will get trapped in their poo discharge and prolonged condition are sometimes blamed as the cause of flipping disease seen happening on goldfish. Therefore use only sinking food pellets for your goldfish.

Animal feed pellet, animal feed production line

 Good animal feed production line can get high-quality feed pellet.

Mixing factor. Mixing is the most important part in feed production. If the mixing is not uniform, it will cause local concentration of nutrients will be too high or too low.
The indicator of mixing quality is mixing uniformity. The factors affecting the uniformity of mixing include following factors
1. Mixer types. Different types of mixers with different performances. At present, the better mixers are twin-shaft blade mixers, but they are more expensive.
2. Raw material properties. The powder size, adhesion, fluidity, bulk density, etc. of each component of the mixed material are different, which makes the material mixing uniformity quite different.
3. The order of feeding. For different formulations, the order of addition should be different. As a general rule, the components with large proportions are added to the mixer first, and then small amount or trace components are added, the components with small specific gravity are added to the mixer first, and the components with small powder size are added later.

I could tell you that the fish feed machine is popular in Lima.
Pelleting factor. High temperature, high pressure and high moisture are involved in the pelleting process, which is extremely disadvantageous to some substances with heat sensitivity, easy oxidation and good solubility, especially vitamins and enzyme preparations. For example, vitamin C loses 15% to 20% during the granulation process, vitamin A can withstand does not exceed 70°C. If the temperature of feed pellet machine is too high and the moisture content is too low, it will promote Maillard reaction and cause protein The digestibility and the reduction of amino acid potency require proper processing and conditioning to maintain a stable steam pressure. Use saturated steam in pellet production and the steam temperature should be controlled to the lowest limit of normal production. And if you are really interested in it, you can go to learn about the animal feed production line.
Other factor. The long screw conveyors and scraper conveyor has adopted in animal feed production line, this will cause cross-contamination between raw materials and different formulations. Therefore, equipment clean-up procedures should be strict during work, and corresponding feeding and batching sequence procedures should be formulated. The principle is good first and then other materials, which can control cross-contamination to a minimum.
Due to the friction between the materials in the production process, static electricity is generated, causing some materials, especially the additive materials, to easily adhere to a certain kind of material or equipment. Therefore, the user should pay attention to the added materials that are prone to static electricity, and multi-stage dilution should be carried out.
Generally speaking, the above major factors should be considered to eliminate or minimize the difference in the production, which can ensure the quality of the finished product and the formula.
Pelleting costs money and better pellets cost a little more. Payback comes in the form of convenience in handling the feed and more efficient use of the feed by the animal. Improved efficiency is due in part to heat processing which reduces pathogens and makes starches more digestible. A significant portion of the improvement is related to the physical form of the pellet. Durable pellets reduce waste, reduce segregation, improve palatability, and allow larger meals to be eaten in less time. All these factors contribute to optimized feed efficiency.

I must say any machine we can make according to your requirement. Lima Machinery can design and make the feed pellet machines according to agents’ requirements, and we can send our engineer to agent country for the technical training and after-sale service if necessary. We can be a professional and reliable choice for you.

Knowledge about complete poultry feed production line

Cattle feed production line with the sole purpose of creating pellets from powder, which allow animals to be more efficiently fed.

At the beginning of 2021, one of our clients in Brazil has purchased a complete cattle feed plant. This is a cattle farm owner who wanna make cattle feed pellet for their own. The customer was feeding cattle with alfalfa before, but the nutrition is very simple, he needs to add grains and vitamins to improve the growth of the cattle. This plant is designed and constructed for processing feed products for ruminants such as cattle and sheep.

The animal’s diet is formulated from a range of potential ingredients, then mixed together to provide all of the poultry animal’s nutritional requirements. The powder which is used to create the feed pellets can come from many different materials. Most of these ingredients are grains, oilseed meals, grass, and animal byproduct meals. Different animals will require a different formulation of feed, the user can also add many diverse leftover materials to make up feedstuff. Maybe you can see the pellet machine.

Benefits Of Animal Feed Pellet Compared with traditional fodder or feed mash, animal feed pellets are more clear, healthier, and provide condensed nutritional benefits to livestock. Feed pellets allow for better control of how many nutrients are available to the cattle.

Tailoring this to the exact requirements of the livestock will naturally lead to increases in the profitability of the enterprise, and not only through the reduction of waste feed. Feed pellets are also an easier and more efficient way for the cattle to consume their nutrients. It is far simpler to move pellets around and store them, as they will take up less space than less nutritionally dense feeds.

Cattle feed production line exist in many different types with the sole purpose of creating pellets from powder, which allow animals to be more efficiently fed. Large-scale production of feed pellet is done using ring die pellet mills while small-scale production utilizes flat die pellet mills. The cattle feed mill machine is differ in sizes based on your needs. It is always integrated with crushing machine, mixing machine and pellets cooling equipment in complete feed processing line. And seeing the animal feed pellet machine.

Processing Step of Cattle Feed Production Line Crushing: Too large is not good for digestion and absorption and also affects the mixing uniformity. Too small is easy to lump and not good for chewing and digestion. The optimal powder size should be considered according to various factors including the type of livestock and poultry, the nature of feed, feeding way and processing cost.  Mixing: The ribbon mixing machine is used after the crushing machine to mix the grinded raw materials equably. The machine has a large barrel, in which all the ingredients with different portions are mixed properly, and then mixed powder for later pelleting.

Pelleting: The feed pellet machine presses feed powder to form pellets with uniform size (the pellet size can be 2~8mm). Flat die pellet mill and a good choice for making forage pellets in small and medium size processing plant.
