1.采用先进预混料饲料配方

The formula of家禽鸡猪牛牲畜预混饲料是生产技术的核心。它是由专业的动物营养专家制作的premix feed mill lineaccording to the characteristics of the nutritional needs of the animals at each stage of growth and production, and the basic nutritional content of domestic feed ingredients. What to make up for what, economical and reasonable, low-value and high-efficiency as the principles, while considering the external environment andpremix feed processing technologyand other factors, carefully designed. On the one hand, the appropriate and appropriate amount of additive materials should be selected in combination with nutritional needs, user feeding levels and conditions; on the other hand, processing needs should be considered. For most components that do not affect safety, such as nutritional additives, mastering the appropriate amount is the formulation technology key.

药物饲料添加剂和某些敏感成分（如硒，铜等）的剂量和用法必须具有足够的科学依据和必要的实践经验。否则，易于发生错误，后果严重。原材料的比例是影响预混物质量的重要因素。活性成分与稀释剂的比例，各种微量元素的比例，与预混物中的相关活性成分的比例应该是正确的。公式不应该是不可变的。它应根据市场反馈，当地条件，季节性变化，最新技术和产品信息，严谨但灵活，并始终使其不断调整公式pig chicken cattle livestock poultry premix feedproducts close to the national conditions and actual production.

2. Choose high-quality raw materials

原材料的质量有很大的妊娠和分娩综合管理t on the actual utility of the premix. The most basic requirements for high-quality raw materials are high purity and no toxic and harmful substances. The most important thing is the content of active ingredients, especially vitamin A and vitamin C, which are easily destroyed. For other additives, the dosage should be determined after actual measurement. The raw materials of trace element compounds must have the characteristics of high biological potency, stable physical properties and few toxic and harmful substances. In addition, some additives, their quality and dosage form are likely to affect other additives, so special attention should be paid. For example, the hygroscopicity of ferrous sulfate heptahydrate is very strong, and it is also very destructive to vitamin A, while the effect of ferrous sulfate monohydrate on vitamin A is relatively small. If a protective agent is added, the impact is even smaller and itself The activity is very good.

中国供应动物饲料厂用于制作动物牲畜马山羊鸭狗牛虾猪猪预混饲料should select high-quality raw materials, and accurately determine the quality and potency of the raw materials.

When choosing vitamins, pay attention to the following two points:

① Choose high biological value;

②Choose different vitamins according to climate characteristics. For example, thiamine mononitrate is better than thiamine hydrochloride in hot and humid summer. When selecting trace element raw materials, many factors such as the content of its ingredients, particle size, crystal water and the content of toxic and harmful substances should be considered.

③Medicine feed additives should also pay attention to safety issues. When using them, they must fully understand their use period, withdrawal period and precautions according to the instructions and the test materials provided by the manufacturer.

3. Use the best carrier and diluent

Carriers are particles that carry or adsorb a small amount of active ingredients, which are inactive substances in the premix. The selection of the carrier should follow the following principles: strong chemical stability, no damage to the adsorbent; moderate particle size, good mixing with complete feed; low price. The particle size of the carrier should be between 0.177~0.59mm; the density should be similar to the density of the microcomponents it carries. The carrier density in the composite premix should be the average of the density of each microcomponent; when mixing the carrier and additives, add 1.5% vegetable oil can improve the adhesion of the carrier; the water content of the carrier should be controlled at 8%~10%, and the carrier should not damage the activity of the active ingredients it carries; the pH of the carrier should be close to neutral. Commonly used carriers are: shell powder, wheat bran, corn, bran powder, defatted rice bran, stone powder, zeolite powder, salt and so on.

稀释剂是减少预混物中活性物质浓度的组分，并将微粒彼此分离。它是载体的不活性物质，并在减少活性成分之间的反应并利用活性成分的稳定性起作用。稀释剂的要求是：稀释剂的水含量应小于10％，没有吸湿，无凝聚;粒度要求在0.05〜0.6mm之间;表面应平滑且具有良好的流动性;pH值要求5.5和7.5，没有静电电荷;它必须是可食用的，无害和稳定的。

4. Raw material pretreatment

维生素容易受到氧气，湿度，热，光，金属离子等的因素的影响，这减少了活性。为了满足预混料饲料制造过程的要求，所有维生素添加剂必须经过特殊的预处理以维持其稳定性和活动。乳化技术可用于形成均匀分散在基质中的颗粒，然后涂层技术可用于形成明胶涂覆的颗粒以制造微胶囊。以这种方式处理的颗粒可以抵抗机械操作，具有良好的抗氧化性和良好的混合性能。

Trace element additives mainly refer to mineral salts and oxides such as copper, iron, manganese, and zinc. Some of these compounds have poor water solubility, and some are easy to absorb moisture and return moisture. Appropriate pretreatment must be carried out before application to change some of their physical properties, so that they can meet the requirements of processing technology and ensure product quality. The pretreatment technologies used mainly include drying treatment, addition of anti-caking agents, coating, granulation, and pre-crushing.

5.使用高精度premix feed production equipment

Scientific premix feed formulas must be realized by accurate metering ingredients. To ensure accurate ingredients in strict accordance with the requirements of the formula, advanced metering equipment and reasonable technology are necessary. There are very high requirements. Therefore, management and regular calibration of related equipment should be strengthened. For drugs that are added in small amounts and affect safety, such as selenium, high copper and other additives, be especially careful in metering and dilution. The鲶鱼狗鸡牛山羊家禽预混饲料混合器is the most important feed equipment for making premix. Different types of premix feeds need to choose different cattle poultry pig fish premix feed mixing machine, such as双螺旋带预混料搅拌机那double shaft paddle horizontal premix feed mixers那etc. In general, the requirements for premix mixers are:

①High mixing efficiency and short optimal mixing time;

②搅拌均匀性;

③Reasonable structure, low residue in the machine and easy to be removed;

④易于装载和放电;

⑤致气密性能和少量泄漏;

⑥防静电。

6. Mix well

Feed mixing is only a physical process, but due to obvious differences in the characteristics of raw materials such as density, equipment, mixing time, and suitable carriers or diluents must be selected scientifically. The预混料饲料生产过程尽可能简单和努力是统一的吗. For a high-quality premix, all its components should be evenly distributed. Take any sample for testing, and the ratio of its multiple components should be consistent with the formula. However, due to various factors, there will be differences between different sampling and different batches. The poor uniformity of the premix means that the actual intake of the animal does not conform to the prescribed supply amount of the formula, which directly affects the added effect and the feeding effect of the compound feed, especially for some safe doses and poisoned doses. In terms of micro-components, poor uniformity may cause unsafe use, so uniformity is an important quality indicator of premix. The index to measure the uniformity is the uniformity of mixing, expressed by the coefficient of variation. Taking China as an example, the standard stipulates that the coefficient of variation should be less than 7%.

7.介绍HACCP管理系统

Today, when meat food safety is more and more important, it is very necessary to introduce HACCP management system in the production of premix. Firstly, analyze the hazards that may occur in the feed production and processing process, determine the critical control points, and formulate control standards, and then implement practical and effective control measures, establish detection methods and procedures, and find out whether the control measures are consistent with the set standards. If there are deviations, take effective corrective measures, timely adjust production processing and control methods, and fully verify the HACCP system. The implementation of HACCP can improve the quality control awareness and quality control level ofpremix feed processing line那and will surely promote the overall improvement ofpremix feed productionlevels.
