Feed formulation design ideas

Feed formulation design work is a very interesting, very logical work, but also contains many things dialectical method. Not simply a recipe to several raw materials mixed together, not only the need for animal physiology, biochemistry, organic chemistry have in-depth understanding, but also on raising standards, types and characteristics of feed materials using nutrients lies at the chest while keeping the flexibility to apply criteria based on the actual situation. Here is the recipe I have time to do some feelings and experiences in a feed mill for you peer reference.

Quality must be noted that the palatability of feed and raw materials

Some formulators do feed formulation, the only mechanical input to the various feed ingredients to the recipe software, and then click on the "linear programming", as long as the formula of nutrients out of reach, and put the recipe and then submitted to a print production on needed. In fact, doing so is extremely irresponsible, although nutritional supplements reached, but feed the "customers" of animals like it or not is really important. Because poor palatability of feed, animal feed will be little or simply refuse to eat. Therefore, selection of raw materials must choose palatability, no deterioration of fresh raw materials. Formulators should not just do a day in the office at the computer to do recipes, each feed must be done in person before a group to look at the quality of raw materials, the necessary time to personally taste raw palatability. There is a feed made ​​out when you want to test it after feed color, smell whether standards. Some feed mills often like to do some anti-stress, and increase lean meat, and promote animal growth of special packet of materials, because relatively speaking, than the obvious effect of this packet of materials, the profit is relatively high. For example, once I do a control mosquito breeding farm parcels material, the main component of this small material called cyromazine, the main role is used to kill mosquitoes eggs. When do such small material cyromazine did not notice the smell is quite unpleasant, just add some carriers and antibiotics in the recipe. The results reflect the customer antifeeding added this little pig feed material, then adjust the recipe when added flavors and sweeteners, then the market reflects this small material has been very good. Another time a similar thing is that some customers complain about our company a small material (main ingredient is yellow amines and amine synergists yellow) growth-promoting effect is not good, then it has increased the amount of two sulfonamides and trimethoprim times, to keep up with examples like the result, or refuse to eat such a small animal feed, the reason is very simple, because these drugs additives have been bad taste and palatability, the time when the amount of the increase will inevitably increase the unpleasant taste, so the sulfonamides and trimethoprim amount to 1.5 times the original amount, but also adds some flavor, so that the effect will be much better formulations.

Stress that it is important to note the quality of feed ingredients, such as rice bran, wheat bran and other raw materials. Fresh rice bran will have a fragrance smells taste in your mouth sweet side, inside a green shell in general are fresh bran rice bran, rice bran in this compound can be used in 50 percent duck. However, due to the high fat content of rice bran, especially in the summer in the South it is easy to rancidity (5 days or so), so when used in pig feed must pay attention, because the pig is very sensitive sense of smell, can not try to do, you can use cassava to instead. Wheat bran and flour two materials is actually a very easy to rancidity class materials, but many formulators ignores this, so when using wheat bran also pay attention to the freshness of wheat bran, or else there will be poor feeding of animals phenomenon. Fishmeal is a good raw material, but fishmeal adulterated (urea, protein powder) phenomenon is the most serious. There are times I suckling pig feed diarrhea very badly, by reducing the protein, add zinc oxide, citric acid method but the total can not be resolved, then had to take all kinds of raw materials inspection, other raw materials are normal, only fish tested found inside doped ammonium salt. Then put the recipe fishmeal removed, diarrhea problem immediately solved. Because of poor quality fishmeal control, so some companies can buy their dried fish, and then processed into fishmeal. Dried price of 3400 yuan / ton, processing costs 50 yuan / ton, but also cheaper than soybean meal. This not only reduces the cost of fish meal, but also to ensure the quality.

Small feed processing unit's match and installment

So-called small feed processing units, which include mainly 3 most: Mills, the lift, mix blender. The matching and installation techniques are as follows:

1, mills Mills is the most commonly used feed processing machinery, the current domestic production the main hammer-mills and roller mills. shredder can be by a variety of different feeding requirements feeding the raw materials into different-sized particles. The machine models are different, and each hour of processing is also different, the motor model is also different. You can fish in accordance with the size to buy. The general chicken coop should be purchased two, one with, - a desktop replacement.

2, blender blender is generally divided into general feed mixers and additive blender. General feed blender has vertical and horizontal. Vertical blender mixing time is typically 15 minutes - 20 minutes, horizontal, is about 10 minutes, the blender with fodder, should call the jar. Vertical blender of benefits is evenly mixed, and power consumption less. The only flaw is a hybrid time is long, low productivity, loading, the material is not sufficient. Bedroom blender main working parts of stirring blades, the blades are both the inside and the outside layers, the spiral in the opposite direction. In the course of their work leaves stirring fodder, so that both the inside and the outside layer feed relatively to mix of purpose. Bedroom blender the advantage of high efficiency, loading, the material quickly, the weakness is that power consumption is large, large footprint, and the price is relatively high, so it is generally more rarely used.

3, the lift lift-to-doo-lift and spiral up the two, in general the spiral lift.
Again, the small feed processing units of the installation. Install feed processing units of the installation order is to install mills, install the motor and drive belt. Blender installed in Mills, the mills of the feed throat with the blender hopper exactly. Raise the connection to hang and mills of the import.

When processing, the main raw materials down, PIT, lift the raw materials to mills, crush, and then given to the people of Blender mixed in the warehouses, and other raw materials to the feed port directly, mixed compartment.

Feed pellet machine - roller gap adjustment

Roller feed pellet machine (or a roller) gap adjustment is critical for the use of feed pellet machine.

Feed pellet machine for daily use have two kinds, namely flat die feed pellet machine and ring die feed pellet machine two major categories. Roller gap of flat die feed pellet machine adjustment is very simple and intuitive, gap depend directly on the roller at the upper end of the adjusting screw can control the mould pressing wheel, operation boot and feeding test can be carried out.
Ring modes of feed pellet machine is our most commonly used feed pellets, the higher price of the machine. This kind of roller gap adjustment of feed pellet machine relatively trouble. The first is to mould cover is opened, we can see directly is the roller frame plate, roller frame plate at both ends of the two adjusting discs, the screw loosen the fixing disk, or outward to push and pull the disc position, close to the mould is a small gap, away from the die for the large gap. After adjustment, manual rotation of feed pellet machine, with not too tight but can be mutually rub for reference. Then close the cover, switch on the power, test run, if the voice of the normal operation of invest a small amount of raw materials, production test. If the discharge is normal, can be put into production, if the engine abnormal sound or discharging is not smooth, will stop the feed pellet machine, carries on two times of mould pressing roll gap adjustment.

Particularly worth mentioning is that the flat roller gap mold feed pelleting machine and ring modes of feed pellet machine adjustment must comply with current within the rated range, the voice of the normal operation of the feed pellets and smooth discharging these rules. In addition, ring modes of feed pellet machine remember is adjusted in the power-off state, because the operation adjustment will have great danger.

Feed pellet machine manufacturers of professional, experience the use of feed pellet machine of professional Strongwin share with everyone!

How to implement self-sufficient in livestock feeds?

For cattle and poultry, nutritional standards have been prepared with respect to the genotype, environment, quality of available raw materials, maintenance methods, production and reproduction requirements, production capacity and phase of production.

Many country produces soybean, groundnut, rapeseed, sunflower, sesame and cotton meals and these are used as major ingredients in animal feeds. For animal feeds, soybean is the most frequently used oil seed meal and has completely replaced fish meal in poultry feeds. Cottonseed cake and meal are often used in cattle feed throughout the country. Groundnut meal is less popular because of the aflatoxin problem. Rapeseed meal is second to soybean meal in production and second to cottonseed cake and meal for cattle feed. Sunflower meal is commonly used in both cattle and poultry feed.

Feed particle machine belonging to feed pelleting equipment. Based on corn, feed processing machinery.

soybean meal, straw, grass, rice husk, etc. crushed particles directly compressed

Minimal nutrient loss for feed pellet machine,  the machine processing of grain and smooth surface, moderate hardness, degree of internal curing deep penetration. But can kill pathogenic microorganisms and parasites, using a special process, - dry into and dry-out machinery, feed particles in the processing of various additives can be added to the drug, and ensure feed quality. Because dry into and dry out, the water content of less than 12% pellets, convenience store after sealing. Meanwhile gelatinized powder by high temperature condensation under pressure roller extrusion, extruded from the ring mold hole, segmented cutter, and finally get out of the mouth of pellets from the feed, pellet feed naturally cooled before packaging .

The management of laying hens

Feeding and management measures

1 timely transfer group, timely vaccination, insecticide. Egg into the cage work is best done before 18 weeks of age, in order to make the egg became familiar with the environment. Too late is easy to make the part has opened a production of chicken production, or made into abdominal cavity caused by egg yolk yolk peritonitis. In front of the cage or cage at the same time should be vaccinated with live vaccine of Newcastle disease oil, egg drop syndrome inactivated vaccine and other vaccine. Best to conduct a thorough anthelmintic work into the cage, the method such as mites, lice and other parasites on the body surface of spraying drug available. The body of parasites can be oral albendazole 20 ~ 30 mg / kg body weight, or Fu Ding (Chong Kexing) mix material taking. Transfer group, before and after vaccination in the material should be added in a variety of vitamins, antibiotics to reduce stress reaction.

2 timely conversion laying material. In order to meet the increased demand, the layer reproductive system's weight on the growth and calcium, can begin to feed the feed of laying hens at 18 weeks, 20 weeks of feeding egg laying peak feed. At the same time in the material in an extra times the amount of vitamins. This period shall cancel the method of restricted feeding, make chicken feed freely. Turn on the lights during the guaranteed to have the material groove.

3 increasing illumination time. Rural specialist poultry incubation period with natural illumination method. At 18 weeks of age, if the chickens weight reaches the standard, every two weeks to increase light for 30 minutes, until the egg laying rate reached its peak time as total hours per day or 16 hours until 15. If the chicken is lighter in weight, slow growth, but at the same time increase the feeding until 20 weeks of age increasing illumination time. During egg laying light principle is not shorten the time, intensity can not be weakened.

4 for the chicken to create a comfortable environment conditions. Laying hens in the most suitable temperature is 13 DEG to 23 DEG C, the best winter can be maintained at more than 10 DEG C, the best summer can be maintained at 30 DEG C. To maintain the indoor air circulation, prevent all kinds of noise, keep the environment and feeding, drinking water, light stability.

5 The well prevention disease. 

(1) layer into the cage after adding antibiotics in animal feed or drinking water, such as norfloxacin, ciprofloxacin, gentamicin, every 4 ~ 5 weeks administration a week, in order to prevent colibacillosis, salmonellosis, enteritis.

(2) in the feed to add additional regular times the amount of vitamins, in order to adapt to the needs of egg laying chickens and relieve stress reaction, improve the resistance to various diseases. 

(3) to strengthen sanitation management, the implementation of reasonable immune procedure, adhere to the disinfection with chicken and environmental disinfection system, prevent epidemics. Pay close attention to the egg laying rate is consistent with the standards, pay close attention to the external environment on the chickens any small effects.

To combat Egg Chicken-thin shell egg method

Methods for the prevention and control of laying hens eggs with thin shells


(1) adding calcium diet or vitamin D3 observation eggshell thickness changes. If the shell thickness thinning, calcium deficiency; If the eggshell appear deformity, suggesting a lack of vitamin D3, should be properly added.

(2) to adjust the proportion of calcium phosphate in the brood, incubation period, the proportion of calcium phosphate in the 1.5 ~ 2:1, the absorption of calcium and phosphorus utilization rate is higher. Calculation of phosphorus content in the production, we should calculate the effective phosphorus in feed. Plant-based diet, most of the phosphorus in the form of phytic acid phosphorus exist, not easily absorbed by decomposition, so must add phosphates, or adding phytase, to promote the decomposition of phytic acid phosphorus, guarantee of phosphorus in the blood to a certain extent, to keep high gossypol grain in the appropriate proportion of calcium phosphate.


(3) the environmental regulation Should summer birdhouse ventilation cooling, to be warm in winter to keep warm, keep the henhouse appropriate temperature. To strengthen management, keep the henhouse environment quiet, try to reduce stress factors, to create a good environment of egg.
