Duck feed machine

The feed for meat ducks is divided into powder, pellets and crumbles feed according to the shape.

• Powder is the easiest to produce and is less expensive. It has the advantages of simple processing, comprehensive nutrition, low cost, convenient dosing, and the remaining materials are not easy to go moldy. It is a material commonly used by small and medium-sized free-range farmers. The disadvantage is that the powder easily produces dust.
• The pellet feed is made of full-price material plus a binder and then pressed. The particle size is adjustable to adapt to the nutritional needs of meat ducks at different growth stages. Ensure that when meat ducks eat feed, all nutrients are eaten in a balanced manner.
  
  Pellets can also improve palatability, increase the feed intake of meat ducks, and make it easier to obtain the nutrients required for meat duck production performance; make meat ducks less picky eaters, and reduce feed waste. Due to the high temperature requirements during the granulation process, it is also a sterilization process for Salmonella and other harmful bacteria.
  
  During the processing of pellets, the carbohydrates in the feed are gelatinized (gelled), improving the digestibility of the feed. From a feeding science point of view, it is best to feed meat ducks pellet feed because it is nutritious and has good palatability.
  
  It increases the eating speed and amount of meat ducks, reduces the energy consumption of eating movements, and improves the feed conversion rate, meat ducks also gain weight quickly. The disadvantage is that certain vitamins are easily destroyed due to high temperatures during processing.

In addition, ducks like to eat granular feed rather than powdered feed. A high powdering rate will affect feed intake and loss rate. Ducks are sensitive to changes in particle size. Therefore, it is best to feed meat ducks with pellet feed.

RICHI’s duck feed machine can process various duck feed products. The duck feed machine and processes we configure for our customers completely depend on “what kind of duck feed the customer wants to process.”

In fact, there is more than one way to process duck feed:

1. Crushing and flattening:
   Crushing is the most common method of grain feed processing, and the processed products include coarse grains and fine grains. Young ducks should be fed fine grains, and adult ducks should be fed coarse grains. This will help improve the palatability of the feed, increase the duck’s feed intake, and improve feed digestibility.
   Flattening is to heat the grains with steam to about 120°C, and then use a flattening machine to crush them into 1 mm thick slices, which are quickly dried. Since the starch in the feed is heated and gelatinized during the flattening process, the digestibility of the feed can be improved.
2. Granulation:
   That is, making granulated ingredients. After crushing the feed, mix various raw materials evenly according to the feed formula, and then use a duck feed pellet making machine to form granular shapes.
   The advantages of pellet feed are that it is convenient to feed, has good palatability, can increase chewing time, is beneficial to digestion, and reduces feed waste. This is also the process of duck compound feed that has been introduced above. It only needs to use a complete set of duck feed equipment. This method is also the most widely used.
3. Soaking:
   Some feeds such as bean cakes and cottonseed cakes are quite hard and difficult to chew when fed directly, so they need to be soaked to allow the feeds to absorb water and expand, making them soft and easy to chew. The soaking method is to mix the feed with water in a container such as a pool or tank.
   The general ratio of duck feed to water is 1:1 to 1.5, that is, just hold the water droplets between your fingers. For feeds containing harmful substances such as tannins and gossypol, soaking can reduce toxins and their bad taste and improve palatability. Note that the soaking time should be adjusted according to the season and feed type to prevent feed deterioration.
4. Feed formulation and mixing:
   This is the main method of modern compound duck feed production. Its purpose is to produce high-quality feed by formulating according to the nutritional needs of ducks and mixing according to processing requirements, and greatly improve the digestibility of the duck feed.

Duck feed plays a vital role in the overall health and growth of ducks. The composition of duck feed can vary depending on the specific needs of the ducks and the type of production system used. However, there are some common ingredients included in most duck feeds.

1. Grains: Grains such as corn, barley, wheat and oats are the main energy sources in duck feed. They provide the necessary carbohydrates and proteins required for growth. Corn is the most commonly used grain in duck feed because it is readily available, palatable and provides an excellent source of energy.
2. Protein: Ducks require a high-protein diet to support their growth and maintain their feathers and muscle mass. Animal proteins such as fish meal, meat and bone meal, and soybean meal are often used in duck feed to provide essential amino acids.
3. Fat: Fat is an important energy source for ducks and helps to increase the overall energy density of feed. Vegetable oils such as soybean oil, corn oil, and canola oil are commonly used as a source of fat in duck feed.
4. Minerals: Ducks need a variety of minerals to support their growth. These include calcium, phosphorus, sodium and potassium, which are all essential for the development of strong bones and maintaining proper body function.
5. Vitamins: Ducks need a variety of vitamins to support their growth and overall health. These include vitamins A, D, E, K and B-complex vitamins. Vitamin supplements are often included in commercial duck feeds to ensure the ducks get all the vitamins they need.
6. Fiber: Fiber is an important component of duck feed as it helps promote digestive health and prevent digestive diseases. Sources of fiber in duck feed may include alfalfa meal, wheat bran and other fiber by-products.

In summary, duck feed is a complex mixture of ingredients that must be carefully balanced to meet the specific needs of ducks. A good quality duck feed should provide all the essential nutrients, vitamins and minerals required for growth, maintenance and good health.

Controlling the powder content of duck feed actually means controlling the starchy raw materials such as corn, wheat, and cassava in duck feed.

• Corn: The binding force between protein and starch granules is weak, the structure and texture are soft, and there are air gaps in the endosperm.
• Hard wheat: The binding force between protein and starch granules is strong, the structure is tight, and the texture is hard.
• Cassava: The protein structure is denser and harder than that of wheat.

We already know that for this difference in starch raw materials, we should:

1. In view of the structural strength and hardness of wheat and cassava starch, the fineness of crushing should be increased and the proportion of damaged starch should be increased as much as possible.
2. In view of the tight structure of wheat and cassava starch, the conditioning time should be appropriately extended and the conditioning temperature should be increased before granulation.
   • Conditioning time: no less than 25 seconds
   • Conditioning temperature: The surface temperature of the duck pellet machine conditioner should not be lower than 90°C, and the material temperature should be kept above 80°C.

Sure. We can supply whole set of fermented feed machine for duck feed mills.

1. Preparation and application methods of fermented feed

• Fermented complete feed: 2 tons of complete duck feed (you can also mix soybean meal and corn half and half), 1-2 packs of “feed starter”, 1-1.2 tons of clean water, seal in a plastic container and ferment for more than 7 days. Mix it with duck feed at a ratio of 10%-30% and feed it. You can also feed it alone according to this ratio, and it should be staggered with the full-price feed.
• Fermented cheap feed:
  Such as fermented cassava dregs, bean dregs, rice noodle processing leftovers, factory and school leftovers, rice bran, uniform bran, fungus bran, distiller’s grains, pomace peel, green straw, pasture, sweet potato vines and other raw materials 99 multi-functional 1 pack of feed starter and 1 ton of raw materials to be fermented (some raw materials need to be crushed), 100 kilograms of starch-containing feed (the proportion is about 5% or more of the raw materials, such as corn, rice, sweet potatoes, and starch, or more than 1 kilogram of polysaccharide compound bacterial strain nutrient base instead), 2 kilograms of salt (raw materials containing sufficient salt will not be added.
  • Salt cannot be placed in the activated bacteria, but should be sprinkled directly on the fermentation material or in the clear water that needs to be added. ).
  • The moisture content is adjusted to about 55%-60%, and it can be used when it is compacted, sealed and fermented for about 7 days and has a strong aroma.
  • The palatability, nutrition, and digestibility of the fermented material are significantly improved compared to those before fermentation.
  • The fermented feed should be mixed with other full-price feeds of the animal at 10%-50% according to different animals and different feeding cycles and then fed. It cannot be fed alone or fed with all fermented feeds.

It should be noted that processing fermented feed does not mean not processing pellets. Fermentation is a type of process, and the form of pellets is what ducks like to eat. Therefore, duck feed machine can still be used to process fermented feed and used together with fermentation equipment.

2. Benefits of fermented feed for ducks

It is very difficult to improve the economic benefits of large-scale meat duck breeding if all the ducks are raised with full-price feed. Coupled with transparent competition, it is difficult to win more benefits except through quantity.

Most farmers know that poultry have short intestines and poor digestion of feed. Ducks are no exception. Only a part of the feed will be digested and utilized by ducks, and the remaining nutrients will be excreted from the body before they are absorbed. , causing great waste. In order to avoid this situation, improve feed utilization and reduce feed costs, many people began to try to use fermented feed to raise ducks. Facts have proved that the effect of fermented feed did not disappoint them.

There are two main reasons for the low utilization rate of ducks fed ordinary feed.

• First, the duck’s own intestinal tract is short, and the digestion time of the feed is short. There is not enough time for the duck to slowly decompose and utilize the feed.
• Second, most of the general feeds are corn, bran and other feeds that contain a lot of crude fiber and lignin. Ducks themselves have poor digestion ability.
• In addition, the feeds they feed are macromolecular substances that are difficult to be digested and absorbed by animals, so the utilization rate of feed will certainly not be very high.

Fermented feed uses organic acids produced by the reproduction of beneficial microorganisms to soften and decompose the feed, and convert macromolecules such as crude fiber and lignin in the feed that are difficult to be digested and absorbed by animals into small sugars such as simple sugars and amino acids that are easily utilized by animals.

Molecular nutrients save ducks the time of decomposing the feed and can be digested and absorbed directly. The utilization rate of the feed will naturally be improved.

The fermented feed contains many beneficial microorganisms. The organic acids produced by these microorganisms when entering the duck’s body along with the feed will regulate the acid-base balance in the duck’s intestines, promote intestinal peristalsis, enhance the duck’s own ability to digest the feed, and further improve the duck’s ability to digest the feed. Feed utilization.

Using fermented feed to raise ducks can save 10% to 20% of feed costs. Although it may not seem like much, it can save farmers a lot of feed expenses on a huge base, reduce the economic investment in breeding, and increase breeding in disguise. the economic benefit of the person.

Meat duck feed preparation technology requires reasonable configuration of duck feed ingredients and proportions, mainly including energy, protein, fat, fiber, minerals and vitamins.

• According to the nutritional needs of meat ducks at different stages, appropriate raw materials should be selected and mixed in proportion for processing.
• At the beginning of the growth period, feed mainly high-protein, high-energy, and easily digestible feeds, such as soybean meal, corn, fish meal, etc.;
• In the middle and late growth period, the crude fiber content should be increased appropriately, such as silage corn or pea seedlings, etc.
• In terms of the type and use of meat duck feed, complete feed, concentrated feed, concentrate and additives can be used.
• Complete compound feed ingredients include corn, soybean meal, wheat bran, etc., which can meet various nutritional needs of meat ducks;
• Concentrated feed refers to high-quality feed that has been concentrated, such as corn lactic acid bacteria fermentation liquid, wheat germ, etc.;
• Concentrated feed is a highly nutritious feed made using modern technology, such as amino acid, nucleic acid feed, etc.;
• Additives can improve the nutritional value and taste of feed, such as enzymes, etc.

When using duck feed equipment to produce fat-containing laying duck feed, the following aspects should be paid attention to:

• Add oil: Add more than 3% palm oil when mixing.
• Ring die aperture: Φ4.0 or Φ4.5
• Quenching and tempering temperature: has reached 100℃, ring die compression ratio: has been used to 1:16 or 1:19, but the problem of powder content still cannot be solved.

We believe that when adding a large proportion of grease and enzyme preparations, which seriously affects the granulation and molding, you may wish to choose spraying after granulation. There are three suggestions as follows:

• Difficult to spray: Use a screw pump (4KW) without adding water, heating and temperature control of 60°C, pressure of 6 kg, and lift of 30 meters.
• Molasses: (vertical) viscosity 79-80%.
• Difficult to granulate: The resistance through the inner hole of the die hole is large, so appropriately reduce the compression ratio of the duck feed pellet machine ring die

(1) Stainless steel ring molds cannot be used for laying duck feed

The quenching hardness of stainless steel ring dies is generally only HRC.52–54, while the quenching hardness of alloy steel ring dies reaches HRC.59–63.

The feed for laying ducks not only has a high crude fiber content, but also the most terrible mineral content, especially the use of shell powder, low-grade bentonite, stone powder and other raw materials. Mineral raw materials are inorganic substances and cannot be gelatinized or softened despite being tempered. Mineral components that cannot be softened will definitely cause abnormal wear on stainless steel ring dies with low hardness.

(2) Irregular wear similar to hexagonal holes or multi-angular holes appears in the inner hole of the ring die

Reason: When using shell powder, it cannot be crushed, and the raw material particles are too large. When passing through the inner hole of the ring die, the inner hole will be scratched, causing the die hole to vary. A more realistic control measure is to adjust the mineral content and crush the raw material. Fineness.

(3) Analysis of cellular wear

Livestock and poultry feed using ring dies, especially duck feed with a large proportion of crude fiber and mineral content, are more likely to appear honeycombed when using ring dies. This is mainly due to poor discharging and the circumferential damage to the bell mouth of the ring die caused by extrusion friction. , the appearance of honeycomb can be solved by improving the tempering and ring mold design, rather than the usual saying that honeycomb is normal.

In the formula of duck layer feed, the requirements for the selection of raw materials are: stable quality, sufficient quantity, appropriate price, and local resource advantages to reduce feed costs.

Formulate the laying duck diet according to the duck’s age group and feed intake, and determine the appropriate nutrient concentration of the compound duck layer pellets.

Reference duck layer feeds formulation:

1. Egg-laying ducklings (1 week to 8 weeks): 58.7% corn, 26% soybean meal, 7% rapeseed meal or cotton meal, 4% stone meal (both bone meal and shell meal are acceptable), special No. 6 premix 4 %, salt 0.3%. It is recommended that all ducklings be fed full-price pellet feed in the first week.

Equipment lubrication is an important means to prevent and delay parts wear and other forms of failure. Lubrication management is one of the most basic and critical tasks in equipment management, and is a vital link in the “management, use, maintenance, and repair” of equipment.

Strengthening the lubrication management of equipment will ensure the normal production of enterprises, reduce the physical wear and tear of equipment, and extend the life of equipment.

The service life and replacement cycle of parts are of great significance to reduce equipment accidents and failures and improve the economic benefits of enterprises.

The “five determinations” and “three filters” system of duck feed machine lubrication are specific systems for standardized management of equipment lubrication in enterprises and cannot be ignored.

(1) The “Five Certainties” are designated points, quality, quantity, regularity, and people.

• Fixed point. Determine the lubrication parts and lubrication points of each piece of equipment, keep them clean and intact, and implement fixed-point lubrication.
• Determination of quality. Use oil according to the grease brand specified in the lubrication card. Lubricating materials and blended oils must be inspected and qualified. The lubrication device and refueling equipment must be kept clean.
• Quantitative. On the basis of ensuring good lubrication, implement daily oil consumption quotas and quantitative oil changes, and do a good job in waste oil return, carry out warehouse withdrawal work, control equipment oil leakage, and prevent waste.
• Regularly. Refuel, add oil and clean oil according to the cycles specified in the lubrication card. For oil with large reserves, sampling and testing should be carried out according to the specified time. The cleaning, oil replacement, cycle filtration and sampling inspection cycles should be determined according to the oil quality.
• Appoint someone. According to the provisions on the lubrication chart, the division of labor among operators, maintenance workers and lubricators for daily refueling, refueling, cleaning and oil changing of the equipment shall be clearly defined, each shall perform their own responsibilities, supervise each other, and determine the person to submit samples for inspection.

(2) “Three filters”

The “three filters” are storage filtering, distribution filtering, and refueling filtering. This is a purification measure taken to reduce the content of impurities in the oil and prevent impurities from entering the duck feed machine with the oil. Specifically:

• When the oil is pumped from the input reservoir to the oil tank for storage, it must be strictly filtered;
• The oil must be filtered when injected into the lubrication container (distribution filtration);
• When the oil is added to the oil storage area of the equipment, it must also be filtered first (refueling and filtering).

In work practice, nearly half of the causes of duck feed machine failure are due to poor lubrication. Reasons for poor lubrication include improper oil use, blocked oil passages, contaminated oil, incorrect refueling methods, and untimely oil changes. Poor lubrication will lead to increased mechanical wear and mechanical failure.

(1) Correctly choose lubricating oil

Select according to the type and label specified in the equipment manual. However, it is worth noting that equipment manufacturers often do not have a complete understanding of the production of lubricating oil products, and the oil product recommendations are often low or high, so they need to be revised based on the actual operation of the duck feed machine.

(2) Prevent abrasive wear

Abrasive wear is abnormal wear caused by the presence of worn particles (fine sand, iron filings, dust, etc.) on the two friction surfaces. It causes extremely serious wear and tear on machinery. Therefore, during the maintenance and lubrication of equipment, special attention must be paid to abrasive wear. The source of abrasive particles is related to maintenance operations and lubrication quality, as well as to the dust content in the atmosphere.

The support points of some machine rotating parts are susceptible to dust pollution. If maintenance and lubrication management are not good, dust remaining at the lubrication points during installation, dust invading from the outside due to poor sealing, contamination caused by poor management of lubricating grease, and poor running-in during initial operation.

Metal powder, poor lubrication system filtering device, etc. can cause abrasive wear, increase friction resistance, and intensify mechanical wear. Abrasive wear has a great impact on the life of machinery.

According to statistics, wear and tear damage accounts for about 50% in industry. It is regarded as the enemy of duck feed machine damage and should be paid enough attention to.

(3) Perform lubrication duties conscientiously during maintenance

During maintenance, the replacement of accessories and lubricating oil should be done carefully. When replacing duck feed machine accessories, the rag used for wiping must be clean. The rag used for wiping important parts should be cleaned before use to avoid dust contamination of the accessories. The lubricated parts of newly replaced accessories.

The installation area must be thoroughly cleaned. For newly replaced gears in the gearbox, they should be run-in, cleaned again and lubricated before being put into normal operation.

If the bearing is a sealed bearing when replacing the bearing, grease has been added to the bearing, so there is no need to add more grease. During installation, protect the sealing cover and be careful not to damage it to avoid grease spillage and dust intrusion; and hot installation is not allowed during installation to prevent lubrication. The grease melted and overflowed.

At the same time, pay attention to cleaning work when replacing bearings. Dust, impurities or moisture in the lubricating grease will cause greater wear on the bearings. When the content of impurities increases to 0.5%, the wear can increase 5 to 10 times. The amount of grease added should be appropriate, generally 1/2 to 1/3 of the bearing cavity.

(4) Master the special requirements for feed machinery lubrication

Feed is used to feed animals, and its safety is very important for feeding and production. The toxic and side effects of pollution on the feed cannot be ignored. This adds special requirements to the lubrication of duck feed machine: equipment lubrication must not contaminate the processed materials to avoid affecting feed quality. In order to meet this requirement, remedial measures have been taken in the design of feed machinery.

First, strict sealing devices are set up in parts that need lubrication, such as packing seals, mechanical seals, labyrinth seals, floating ring seals, etc., to prevent lubricant leakage; second, special materials that do not require lubrication are used, such as oil-containing bearings, to prevent equipment from leaking.

(1) Precautions when using the crusher for duck feed

• The duck feed pulverizer should be fixed on a dedicated foundation for long-term operation.
• After installing the crusher, check the tightening condition of each fastener. If there is any looseness, tighten it.
• Check whether the tightness of the coupling is appropriate and whether the motor shaft and the duck pulverizer machine shaft are parallel.
• After starting up, the crusher should be idle for 2~3 minutes, and then start feeding after there are no abnormal phenomena.
• Pay attention to the operation of the duck feed pulverizer machine at all times during work, and feed the material evenly to prevent clogging of the machine. Do not overload the machine for a long time.
• When it is clogged, stop the machine immediately. It is strictly forbidden to open the cover when starting up.

(2) Wear mechanism of duck feed pulverizer hammer machine

Duck feed hammer mill machine is one of the most commonly used duck feed machine. The rotating speed of the rotor is 1 500~3 000 r/min. Arrays of hammer blades (ranging from 20 to 100 pieces) are evenly distributed in the radial direction on the rotor and rotate at high speed at a linear speed of up to 60~100 m/s, thereby putting the input into the hammer.

Soybeans, corn and other grains in the crushing chamber are impacted and crushed. Since these grains are inevitably mixed with a certain amount of impurities, the corners of the hammer will be worn quickly.

A scanning electron microscope was used to observe the surface morphology of the worn parts of the hammer. From the analysis of the wear streaks and pits with obvious directionality, it was found that oblique impact particles have certain cutting wear and deformation fatigue wear effects on the surface of the hammer.

Nowadays, hammer manufacturers generally use heat treatment to improve the strength and surface hardness of the hammer to extend the service life of the hammer. In order to improve production efficiency, duck feed manufacturers should regularly check the wear degree of hammer blades and replace worn parts in a timely manner.

(1) Precautions during the granulation process

• The material needs to be quenched and tempered before granulation. The pressure of the steam must be stable (0.2 mbar), and the water must be removed from the steam before quenching and tempering. If the steam contains a large amount of moisture, it will cause clogging of the granulation. After the materials are conditioned, they undergo a certain degree of maturation, which can significantly improve the utilization rate of nutrients in the feed.
• During the granulation process, the humidity and temperature of the material should be checked frequently. The way to check the humidity is to check if the material can form lumps after gently pinching it with your hands. The temperature should vary according to different granulation varieties, and should be stably controlled between 75°C and 95°C.
• The particles after granulation must not be cooled too quickly or not cooled enough. If the cooling is too fast, the surface of the material particles will crack; if the cooling is not enough and the temperature is too high, the material will absorb moisture and cause mold. The cooled material should be consistent with room temperature.

(2) Correct operation and maintenance of duck feed pellets machine

• Adjustment of the gap between the ring die and the pressure roller.
  For the adjustment of the gap between the new ring die and the pressure roller, there should be slight contact between the highest points of the ring die and the pressure roller, and the pressure roller reaches a state of “seeming to rotate but not rotating”.
  • If adjustments are made during working conditions, the pressure on the ring die and the pressure roller can be appropriately increased, but it must be done only in moderation.
  • If the gap between the ring die and the pressure roller is too large, the pressure roller cannot rotate, causing the machine to jam.
  • If the gap between the ring die and the pressure roller is too small, the wear of the ring die and the pressure roller will increase, and even the ring die and the pressure roller will be damaged.
  • For this reason, the gap between the ring die and the pressure roller should be checked in time, at least once every 4 hours of work. When adjusting each pressure roller, pay attention to the adjustment direction of each pressure roller. The sum of the moments of each pressure roller relative to the axis of the duck feed pellet machine should be 0, so that the duck feed pellet machine is not affected by asymmetric forces.
• The team maintains the duck feed pellet machine.
  A pre-shift inspection should be conducted before each shift to check all transmission components, instruments, and valves, add lubricating oil (lithium-based lubricating oil should be used), and remove iron filings from ironware.
• Install or replace the ring die and pressure roller correctly.
  Generally, new molds are equipped with new rollers, and old molds are equipped with old rollers, so that the surface shapes of the ring mold and the pressure roller are close to the profiling state.
  • The gaps between the various parts of the ring die and the pressure roller are roughly the same, so that the entire ring die is stressed and discharged very evenly, which can improve production efficiency. Before assembly, cleaning work should be done to ensure that all mating surfaces are clean.
  • Pay special attention to cleaning the screw holes of the ring die. If there is material in the screw holes of the ring die that is not cleaned, it will easily cause the bolt holes of the ring die to break when tightening the bolts of the ring die. Use a torque wrench to tighten the ring die bolts to ensure the specified tightening torque.
  • When assembling the pressure roller, pay attention to the inspection of the bearing. Once damage is found, it should be replaced in time. After assembling the pressure roller, a certain gap should be ensured so that the pressure roller can rotate freely.
  • Be sure to oil the pressure roller on time every shift. If the pressure roller is short of oil, it will cause the bearing and pressure roller shaft to burn, and in severe cases, the entire pressure roller will be scrapped.

The starting point of duck feed machine care and maintenance is to ensure the normal operation of the equipment, save energy, reduce maintenance costs, and extend the service life. The fundamental purpose is to improve the comprehensive economic benefits of the enterprise. Although the company’s mechanical maintenance costs only account for a small part of the company’s production costs, it can have a great impact on the company’s long-term economic benefits.

The damage caused by inadequate equipment care and maintenance is serious, especially when key duck feed machine is damaged. Due to the long procurement cycle of spare parts, it will cause long downtime and stop production, which will affect the completion of the production plan and cause heavy losses to the company’s profits.

All duck feed production enterprises should strengthen the maintenance and upkeep of feed mill equipment to ensure the economic benefits of the enterprise.

(1) Pay attention to safety:

When formulating duck pellets, safety should be given top priority. Only by first considering the safety of the formula feed can we carefully select materials and use them rationally.

• Prudent selection of materials means paying attention to the quality and grade of the feed. It is best to test various duck feeds before batching to make sure you are aware of it.
• Pay attention to whether the feed has deteriorated and whether it is contaminated with toxins. Any duck feed that is moldy, spoiled, or contaminated with toxins is not allowed to be used.
• The dosage of duck feed containing toxic substances must be strictly controlled to ensure rational use of materials to prevent poisoning.
• It is necessary to fully estimate the possible toxicity of some additives and comply with the regulations on their use period and discontinuation period.

(2) Pay attention to nutrition

Nutrition is based on feeding standards, combined with local natural conditions and practical experience, to design a formula that can meet the nutritional requirements of high-yielding poultry and fully unleash the high-yielding potential of the poultry flock.

Whether the duck feed formula is practical depends on whether the various nutrients in the prepared feed synergize and complement each other. Only with reasonable compatibility can the potential of duck feed be maximized.

(3) Give full play to benefits

The ultimate goal of compound feed is to achieve good economic benefits. Only duck feed formulas with reasonable nutritional content, good production performance, high feed conversion rate and high economic benefits after feeding duck have practical significance. When large-scale duck farmers formulate their own feed, they can reduce an intermediate link, which can save costs.
