Ways to get low cost protein for fish feed making

 Fish feed play an important role in the aquaculture production. A balanced fish diet rich in proteins will lead to a greater development and growth of these aqua animals.

In Europe, the production of fish feed is mainly targeted at highly predatory species such as the salmonids, cod, bass and bream. These carnivorous species require a high protein feed. In line with this, the feed receipts have traditionally contained fish meal and fish oil as the major ingredients. Carbohydrates can only be used in limited amounts for energy.

Carbohydrates do, however, often also function as binder for the feed pellets. Small quantities of vitamin and mineral mixtures and other additives are used as well. These additives are important in a monitoring context as they are often regulated in terms of maximal upper limits. And you can go to see the dry type fish feed pellet machine.

Why protein is import in fish feed? One of the most important macronutrients for the fish organism are proteins. High-quality protein and energy sources provide the critical nutritional requirements for the development of body tissues, such as scales, bones, muscle, and nerves. All diets include our exclusive vitamin and mineral premixes, including Stabilized Vitamin C to support metabolism, skeletal development, body fluid regulation, and enzymes.

The ingestion of proteins that contain an adequate balance of amino acids will be one of the determining factors for a good growth and development of the fish. When ingested, the proteins are hydrolysed into amino acids, which will be used for the synthesis of new proteins, with consequent expansion of muscle tissue.

Among the amino acids available in the nature, a part of them corresponds to the essential amino acids. These are not synthesized by the body and must be necessarily acquired through diet. Therefore, it is fundamental that the fish feed has a balance that contemplates all the amino acids that are essential for their development. This factor should be taken into account when formulating feed for this type of animal.

What’s the mainly protein source for fish feed? The main protein source in fish feed has traditionally been fish meal. Fishmeal is made from fish that are ground, cooked, and processed.
It is an excellent source of protein for poultry. It has high levels of essential amino acids such as methionine and lysine, and it also has a good balance of unsaturated fatty acids, certain minerals (available phosphorus), and vitamins (A, D, and B-complex). The use of fishmeal is usually restricted to 5% to 10% of the content of poultry diets.

The quality of different feedstuffs is greatly dependant on the amino acid profile in their proteins, digestibility of the proteins, freshness of the raw materials, and their storage. Plant-based proteins, even when properly processed, are usually not as digestible as fishmeal; and their inclusion rate into the diet is often limited as it results in depressed growth rates and feed intake. Over-all protein digestibility values for fishmeal are consistently above 95%. In comparison protein digestibility for many plant-based proteins varies greatly, for example, from 77% to 96%, depending on the species of plant.
High quality fishmeal provides a balanced amount of all essential amino acids, phospholipids, and fatty acids (e.g.,DHA or docosahexaenoic acid and EPA or eicosapentaenoic acid) for optimum development, growth, and reproduction, especially of larvae and brood stock. The nutrients in fishmeal also aid in disease resistance by boosting and helping to maintain a healthy functional immune system. High-quality fishmeal also allows for formulation of nutrient-dense diets, which promote optimal growth. Welcome to see the fish feed extruder machine.

The fish meal is a limited resource and it is anticipated that the world production will reach a maximum level of about 1.1 million tons. The cost of high-quality fishmeal (65% protein) has ranged from approximately $385 to $554 per ton since the year 2000, or 2.0 to 3.5 times the price of soybean meal. The concentration of high-quality nutrients, especially protein, makes fishmeal one of the most sought and expensive feedstuffs.

Other lipid sources are therefore increasingly being used in aquaculture feed production. The best approach in feed formulation is to use high-quality feedstuffs to manufacture a diet that meets the nutritional and energy requirements of the aquaculture species in question. Fishmeal contains the profile of amino acids that most closely meets the amino acid requirements of fish. If a portion or all of the fishmeal in a diet can be replaced successfully with other high-quality protein sources, doing so will contribute greatly towards protecting the surrounding environment and promoting a sustainable aquaculture industry.

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.

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.
