There are many factors affecting poultry cooperation with feed quality, except for the scientific reasonably used feed formula, the quality of the raw materials used and the quality of processing will directly affect the quality of product quality. The feed formula determines the nutritional value of the feed finished product. 7GZ China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
7GZ China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry [ 123] To design a nutrient rational, low-cost poultry blending feed, and hand-designed methods cannot effectively solve a large number of calculations. At present, a linear planning method is widely used in formula production, using computer computing power, and can complete a large number of calculation tasks for single target (minimum cost) multicultural need for single target (minimum cost), called feed formula. Computer design method. The principle is based on the premium of nutrients and the nutrients and prices of the feed raw materials for nutrients as known conditions, and the cost of satisfying poultry nutrition is used as constraints, and then the cost of the feed is the target design. Operation. Different varieties of poultry and various growth stages of nutrition require standards, various nutrients and typical poultry feed formulations of feed raw materials are stored in software. Users need to adjust the standards required by nutrition when they use. Nutrients and prices of raw materials Wait, enter the corresponding raw material to use the limit conditions and the cost of the formulation, etc., the feed formulation can be directly calculated. The feed formulation of using a linear planning design poultry should be combined with the basics and practical experience of poultry nutrition, because the formulation shown can meet the requirements for the lowest cost of the feed, but it is not necessarily the optimal formulation. Whether it is best to judge according to the practical experience of the producer, adjust and calculate until satisfaction. In addition, the lowest feed formulation cost is not necessarily the best benefits of poultry farming. The best production benefit feed formulation developed in developed countries such as the United States is based on the lowest cost formulation of linear planning, combined with some physiological parameters, production performance, feed raw materials market futures prices and poultry products. Many factors such as market prices, design that makes poultry farmers get the best production benefits.

The processing of poultry mixed feed is generally divided into the reception and cleaning of raw materials, the pulverization, ingredients, mixing, and suppression of raw materials.The granules, finished packaging (or bulk). (1) Raw materials cleaning: It is mainly to remove impurities in raw materials, such as debris such as iron filings and stones. (2) Crushing: The pulverization of feed raw materials is one of the most important processes in poultry feed processing. This process is to make the volume of the gilly or granular feed raw material, smash the particle size required to become a poultry feeding standard. It is related to the quality, production, power consumption and cost of the feed. After the raw material was pulverized, its surface area increased, which facilitates poultry digestion. The grain pulverized grain in the diet of the meat chicken is preferably 0.7-0.9mm in the geometric average diameter of 0.7-0.9 mm. With the increase in age, the size of the pulverized particle size is also increased, and the grain size of the egg hook should be 0.8 mm. (3) ingredients: Type a specific batching device according to a given formula, the process of implicitting and weighing a variety of raw materials is an important part of ensuring the quality of the feed product. Considering that weighing accuracy and partial ingredients may have corrosive, premixed material additives are typically induced directly into the mixing apparatus. (4) mixing: Feed mixing refers to mixing various components in the feed formulation, mixing evenly according to the specified weight ratio, so that each small portion of the whole, even a feed, its ingredient ratio and The same as required by the formula. The feed mixing is good, and the quality of ensuring the quality of the feed is an important role. To make uniform mixing, micro-nutrients such as amino acids, vitamins, minerals should be premixed, and prepreg is made. At pre-}, the amount of ingredients should be added first, and then the amount is added less, and the mixing time is short to be determined by testing the assay of the feed mixing uniformity. The variation coefficient (CV) of the premix is u200bu200bnot more than 5%, while the variant coefficient (CV) required for the feed is not more than 10%. (5) Granulation: Make powder-shaped feed into granular feed to complete by extrusion. The feed mixture is generally added to 4% a 6% water (usually with vapor injection, the suitable temperature is around 98 ¡ã C), and after entering the granulator, the water-moisture content of the feed is from a ambient temperature (a water content of 10%. Around 12%) increased to 15% to 16% of 80 ~ 90 ¡ã C. The moisture plays a lubricating effect when it is extruded, and the heat generates a gelatinating effect of the surface of the plant feed ingredient. When the feed is extruded from the ring mold opening, further friction increases the temperature of the feed to nearly 90 ¡ã C, and must be cooled to a temperature slightly above ambient temperature, while drying to a water content of 12% or less, to enter the next section. (6) Screening and packaging: After granulation, the feed is removed from the screen, and the powder is removed, and the package is stored. Slag and powder return to the process. 7GZ China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry

At present, our national poultry combined with feed is generally used by weight ingredients, intermittent mix, and batch production. This production process can be divided into two categories in practice: a class is the production process of first pulverizing the ingredients and mixing, the other is the production process of pulverizing and mixing after the ingredients. 7GZ China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
Production Technology NBSP; NBSP; . The process flow is as follows: Raw materials receive a cleaning of addition (screening, magnetic separation) a combination ingredient a mixed press particles a screening of one grain product package (bulk) – powder finished package (or bulk) This process is characterized by the raw material to be divided into pulverization, which is conducive to the full functionality of the pulverizer, which can choose a pulverized particle size according to the material characteristics, poultry varieties (growth stage), and object physiological requirements. Since the raw materials are pulverized according to the varieties, there is a need for more distribution bins. At the same time, the operation is troublesome due to frequently replacing the crushing material. But this process has more raw materials, and the formula is multi-change, and the production of high-volume requirements is suitable.

2.2.2 The production process of pulverization after ingredients At present, there is only a few poultry feed production in my country. The process flow is as follows: Raw material receives (color) a ingredients a screening of a mixed a mixed pressed particle Sie one piece of finished product package (or bulk) – Powder finished package (or bulk) The process is: 1 The pioneering is uniformly pulverized. Therefore, the mixed front feed material components are uniformly consistent, which is easy to produce granular feed; 2 can save the silo, because the ingredients of such a process are raw materials and accessories storage. The pulverization warehouse only buffer 3 The continuity of the process requires good performance, high technology level, and the screening process can be sieved directly to the mixer without pulverizing the powdered raw material and the excipient sieve.

In addition to the scientific reasonabilities of the feed formulated, the quality of the raw materials and the quality of processing will directly affect the product quality of the feed together. The feed formula determines the nutritional value of the feed finished product. The low nutritional level or the nutrient ratio is unreasonable, which will seriously affect the feeding effect of the breeding object, and will also cause waste of feed materials. Processing quality, such as mixing uniformity, pulverizing particle size, genosis does not reach index requirements, nor guarantee originalityThe advantages of the party are bound to affect the feeding effect.
