2. Principles of local chicken feed formula
How to make local chicken feed formula? Diet combination is also called ration combination. It is to select appropriate feeds to be used as rations in accordance with the provisions of the feeding standards, so that the amount of nutrients contained in the diets composed of multiple feeds meets the requirements of the feeding standards , Its purpose is to consume the least feed with the lowest feed cost and obtain the most high-quality meat and egg products with the highest economic benefit.
At present, it is common to feed a single feed for local chickens in rural areas, which not only wastes feed, but also affects normal growth and development and production performance. For example, in the feeding and maintenance stage, due to the high growth intensity of the chicks, a higher level of protein diet is required, but it is customary to use various fattening feeds such as millet, rice or wheat and corn, which hinders the growth and development of the chicken. Another example is that the breeder stage requires a higher protein level diet, while supplementing sufficient vitamins and trace elements. However, due to the single diet, the breeder cannot fully exert its egg production performance, and the fertilization rate and hatchability of the breeder eggs are reduced.
If part of the protein feed (bean cake, rapeseed cake, fish meal, etc.) is appropriately added to the feed, and part of the cereal feed (such as corn, sorghum) is added to increase the protein level in the diet, the feed composition can be diversified and the single feed may be lacking. Certain nutrients are compensated. In addition, mineral feed should be supplemented. When the green feed is lacking, a variety of vitamins should be added. Under the feeding condition with comprehensive dietary nutrition, the growth rate of Wei chicken is accelerated, so that the weight can reach the market standard in time. This not only shortens the feeding time, but also saves the feed and reduces the feeding cost. Therefore, scientifically coordinated diets are an effective method and a fundamental guarantee to improve the efficiency of chicken production. The following basic principles should be paid attention to during cooperation.
(1) Refer to and flexibly apply feeding standards
The establishment of the most appropriate feeding standards for the nutritional requirements of native chickens is the basic basis for the implementation of scientific chicken breeding, but in actual application, it should be adjusted flexibly according to the specific conditions of the local chicken breeds, gender, regional environmental conditions, feed conditions and production performance. Appropriate increase and decrease, work out the most suitable nutritional needs. Finally, through actual feeding, adjustments are made according to the feeding effect.
(2) When choosing feed, economic(low cost) principles should be considered
It is necessary to use the same materials that are rich in nutrients and low in price and convenient in source as much as possible. For example, under the prerequisite of clearing all the main nutrients needed for infants, try to use green feeds such as sweet potatoes, pumpkins, potatoes, etc. from the price of health and sources of Kofipin to replace part of the cereal feeds to reduce feeding costs.
(3) Pay attention to the quality and palatability of the diet
Do not use raw materials with pungent odor, mildew, or other harmful substances to prepare feed. There are two aspects that affect the palatability of feed. On the one hand, it is due to the feed itself. For example, sorghum contains tannins. Excessive feeding will affect the feed intake of chickens. Therefore, it is appropriate to account for 5% to 10% of the diet; on the other hand, it is caused by processing, such as suppression. The granulated material can improve the palatability, while the powdered chicken will be sticky and reduce the palatability. Therefore, the powder cannot be ground too fine, and the particle size of various feeds should be basically the same to avoid picky chickens.
(4) The selected feed types should be as diverse as possible
Under possible conditions, the types of feeds used for compounding should be as diverse as possible to facilitate the complementation and balance of nutrients and improve the nutritional value and utilization of the entire diet. The nutritional components of various feed ingredients are shown in Table 4-3.
(5) The ration should remain relatively stable
If it is necessary to change, it should be replaced gradually, preferably with a transition period of 1 week, to avoid stress, affect the appetite of the chicken, and reduce production performance. Especially for breeding hens during the laying period, more attention should be paid to the relative stability of the feed.
(6) Pay attention to the quality of raw materials
It is not allowed to use moldy, rancid and low-quality raw materials (fake beancake, fake fish meal, fake additives, etc.) to prepare rations. The quality must be ensured when selecting substitutes. Each incoming raw material must undergo nutritional analysis to prevent counterfeit feed. Each time the feed formula is changed, a feeding test must be done in advance (2 weeks in advance) to prevent large groups from incurring major losses during feeding.
(7) Improve the storage conditions of chicken feed
Prevent loss and deterioration during preservation. Pay attention to environmental conditions such as temperature, humidity and ventilation in the warehouse. Anti-rodent damage, fire prevention, waterproof, shorten storage time and reduce the oxidation loss of feed. It is advisable to use the ingredients for 2 to 4 weeks each time, and it is best to feed with the ingredients. It can be fed on the day of processing, or within 1 week. Additives such as drugs, compound multi-dimensional and amino acids should be mixed in before feeding and should be mixed well.
3. The proportion of common local chicken feed making raw materials
(1) Energy feed
Corn 40%~60%, wheat 5%~10%, broken rice 5%~10%, bran 5%~15%, oil 1%~2%
(2) Protein feed
Soybean meal 15% ~20%, rapeseed meal 2% ~5% (not used for breeders), cotton seed meal 2% ~4% (not used for breeders), peanut meal 5% ~10%, fish meal 1% ~2% (chicken stage).
(3) Mineral feed
Stone powder (growth period) 1% ~1.5%, stone powder (laying period) 7% ~ 8%, bone meal or calcium hydrogen phosphate 1% ~1.5%, table salt 0.3% ~0.4%.
Trace element additives 0.2% ~0.5% (or according to instructions), vitamin additives 200 to 400 grams per ton (or according to instructions), methionine 0.1% to 0.2%, lysine 0.1% to 0.2%.
4.Design of local chicken feed making formula
Feed formulation design must first determine which feeding standards to use, and then determine which feed materials to use, and then use mathematical calculations to make the nutrient content of the formulated feed meet the requirements based on the price and the restricted ratio of certain materials. There are many formula design methods, and the manual algorithm is mainly introduced here.
(1) Trial and error method
The trial and error method is also called the make-up method. It is based on the nutrient requirements in the feeding standard, and the feed composition is initially designed. The sum (total) of each nutrient contained in the various raw materials is respectively compared with the nutrient requirement in the feeding standard. Comparing the requirements of the chickens, the difference will be solved by adjusting the ratio of the relevant raw materials in the formula, and finally the various nutritional cables can basically meet the nutritional requirements of the native chickens.
The calculation steps are as follows:
①The first step is to find out the breeding standards of native chickens at a certain stage.
②The second step is to determine the feed ingredients and find out their nutrients. It is initially planned to use corn, soybean meal, fish meal (animal protein raw materials) and pre-mixed feed as raw materials for design. Generally, the pre-mixed feed is about 3% of the complete feed, the energy feed accounts for 60% to 70%, the protein feed accounts for 20% to 30%, and the mineral feed accounts for 4% to 10%.
③The third step is to calculate the preliminary formula and crude protein of the feed.
④The fourth step is to calculate the energy of the preliminary formula. Comparing the calculated energy of the preliminary formula with the standard, the energy shortage can be solved by adding grease.
⑤The fifth step is to adjust the balance of amino acids. Balance by adding methionine and lysine. Generally, the amount of methionine added is 0.1% ~ 0.3%, and the amount of lysine added is 0.2% ~ 0.5%.
⑥The sixth step is to calculate the mineral content in the preliminary formulation, see Table 4-5. Calcium and phosphorus are not enough, first supplement with calcium hydrogen phosphate to meet the shortage of available phosphorus. Stone powder can be used to solve the calcium deficiency.
⑦The seventh step is to determine the amount of salt. Generally, the content of feed should reach 0.3% ~0.35%. If domestic fish meal is used, its salt content must be considered (generally domestic fish meal contains 2% salt and the highest is 7%).
⑧The eighth step is to determine the amount of premixed feed. There are many types of premixed feeds sold in the market, and various additives such as vitamins and trace elements are required to be within this amount, and the general dosage is 2% to 3%.
(2) Linear programming method
This is the earliest computer design method that applies the relevant mathematical principles of overall planning to optimize the design of feed formulas. It converts the relevant factors and constraints in the feed formula into linear mathematical functions, and uses the characteristics of rapid computer operations to solve certain constraints. The minimum (or maximum) value under the condition.
(3) Goal planning method
The goal planning method is developed on the basis of the linear programming method. The goal planning is actually multi-objective planning. All goals are treated as processing goals. The goals can be compared with each other based on changes in weights, which gives the formula design Come more flexibility.
The latter two local chicken feed pellet formula design methods are currently widely used methods in computer design of feed formulas, which are not only fast and efficient, but also can optimize the formula and reduce feed costs. Among them, the goal planning method is better. However, the limitation of this law requires certain conditions, that is, an ordinary computer, special feed formula software and a certain trained operator are required. The configuration cost is 10,000~20,000 yuan (calculated based on Chinese market conditions).
5. Commonly used low cost local poultry chicken feed formulation
(1) Feed formula for each stage of free-range chickens
|Chicken feed raw material||Brooding period (0-6 weeks) (%)||Growth period(7-20 weeks) (%)||Laying period(%)|
|trace element additives||0.5||0.5||0.5|
(2) Grazing fattening feed formula
In addition to natural resources such as tender grass, grass seeds, and insects, grazing and fattening native chickens also need supplementary feed. Grazing and fattening native chickens can eat trace elements, vitamins and some protein, so the supplementary feed is mainly energy feed, and some mineral and protein feed can be appropriately added.
|Raw material for chicken feed||Formula A||Formula B||Formula C|
|trace element additives||0.5||0.5||0.5|
5. Processing of Compound Feed for Native Chicken
In addition to processing their own feed, some feed factories also specialize in processing local chicken feed.
(1) Design of local chicken feed making plant process
The processing technology of native chicken compound feed must adapt to various processing materials, and requires reasonable electrical and mechanical equipment, compact equipment installation, advanced process and economic indicators, safe operation, and good product quality. All processes with high noise, vibration and dust should be isolated. Feed mills with large production volumes and many varieties should adopt a relatively complete technological process and adopt an automatic program control system. Small-scale feed mills with small production capacity and few varieties can use manual metering and ingredients.
At present, the technological manufacturing process of local chicken feed production can be divided into two methods according to the production method: ingredients first, then crushed and then mixed, and crushed and then ingredients are mixed. The former is more common. The general locale chicken compound feed making process is as follows:
①Raw material storage
The capacity of the chicken feed making raw material warehouse is generally available for 15 to 30 days of production. Raw materials are mostly used in factories for transportation and storage, but the development trend is bulk transportation and storage. The advantage is that it can save packaging costs and facilitate mechanized operations.
② Raw material cleaning
In order to ensure safe chicken feed production, raw materials must be cleaned, and the purpose of cleanup is mainly to remove impurities and iron.
③Raw material crushing
The crushing particle size of feed ingredients should be determined according to the different species of chicken, and calculated according to the aperture of the sieve passed during crushing. Taking chicken feed as an example, the size is less than 1 mm for Victoria chickens, 2 mm for young chickens (4.5 mm pellets), and 2 -2. 5 mm (6 mm pellets) for adult chickens.
The batching process is an important part of the chicken feed processing technology. The main requirement is accurate proportion of ingredients. At present, most chicken feed mill factories have adopted automatic weighing and batching systems, which are accurate and fast, saving labor.
Mixing is the process of mixing the formulated feed evenly during the production of local chicken compound feed. Through mixing, any part of the whole batch of feed can meet the ingredient ratio specified in the chicken feed production formula, and their coefficient of variation should not be greater than 10%.
Processing the prepared powdery batch into pellets is called granulation. Generally, the process of manufacturing chicken pellet feed includes raw material crushing-batching-mixing-steam conditioning-granulation-cooling-screening-packaging. Some of the early feeds for native chickens are columnar pellets made with 1.5 mm aperture ring dies of animal poultry chicken feed pelletizing machine, and most of them are made into pellets with 2.5 ~ 3.0 mm aperture ring dies, and then crushed and classified by a poultry chicken feed grinder machine. The fine materials are returned to the chicken feed. Then cools and packs the pellets that meet the granularity requirements. The late-stage pellets of native chickens are generally pelletized with a 2.0-3.0 mm diameter ring mold, and no more crushing process. The components of the pellets will not be separated, the native chickens are not picky when eating, and there is less waste.
⑦Finished product packaging, storage and transportation
Most products are packed in bags, with plastic woven bags ranging from 40 kg or 5 to 10 kg. The finished products are loaded and unloaded with a forklift and stacked on the backing plate of the finished product warehouse. Each manufacturer stipulates a period of use according to the characteristics of the product, and indicates it on the label.
