Premixed feed is a kind of homogenous mixture of many additives of the same kind or different types of additives in a certain proportion. Although the proportion of premixed feed in total feed is very small, it plays an extremely important role in the feeding effect of full price feed. The purpose of the production of premix is to make the effective components of the additive disperse evenly in the formulated feed after dilution and expansion.

1.正确认识预混料的功效

1. Correctly understand the function of premix

在规模饲养条件下，必须提供给动物全价配合饲料。要配制一种全价配合饲料，预混料必不可少，应考虑日粮中粗蛋白质、必需氨基酸、能量、钙、磷、等营养指标，再配合科学、合理的预混料，只有这样才能发挥其提高动物生产水平、降低饲料消耗及保健等作用。要分清各种营养成分在动物营养中的作用，不能过分强调预混料的营养和生理作用，只有在日粮中主要营养指标合理的前提下，预混料的作用才能表现出来。

Under the condition of large-scale feeding, full price compound feed must be provided to animals. In order to prepare a kind of full price compound feed, premix is necessary. The nutritional indexes of crude protein, essential amino acid, energy, calcium, phosphorus, etc. in the diet should be considered first, and then scientific and reasonable premix should be combined. Only in this way can it play its role in improving animal production level, reducing feed consumption and health care. In order to distinguish the role of various nutrients in animal nutrition, we should not overemphasize the nutritional and physiological functions of premix. Only when the main nutritional indicators in the diet are reasonable, can the role of premix be demonstrated.

2.合理选择预混料

2. Reasonable selection of premix

市场上销售的预混料品种很多，在选购时必须从实际出发，根据自己拥有的饲料原料状况，因地制宜的选择使用预混料。若既有能量饲料原料，又有蛋白质原料，可选用添加量在4%~5%的复合预混料（金典系列、蛋多三宝系列）；要选用技术力量强、产品规格全、质量稳定、售后服务周到的厂家生产的预混料产品；根据当地农副产品种类，选择适合自己拥有的基础料种类和特性的配方类型。

There are many kinds of premix sold in the market. When purchasing, we must proceed from the reality and select the premix according to the situation of feed raw materials that we have. If there are both energy feed raw materials and protein raw materials, the compound premix with 4% ~ 5% addition can be selected (Jindian series and daduosanbao Series); premix products produced by manufacturers with strong technical force, complete product specifications, stable quality and considerate after-sales service should be selected; according to the types of local agricultural and sideline products, the formula suitable for their own basic material types and characteristics should be selected Type.

3. 严格识别质量、明确适用对象

3. Strict quality identification

在购买预混料时，应正规厂家（北京一诺天邦）的产品，并仔细验看包装是否规范、标签内容是否完整。标签上应注明如下项目：产品名称、适用阶段、主要成分、药物添加剂的种类及含量、添加比例、使用说明、生产日期、保质期、执行标准、批准文号、生产企业名称、地址、电话等。还要对产品质量作感官判定，合格的预混料应粒度大小基本一致，色泽均一，无异味、霉变、吸湿及结块等现象。在使用预混料时，应针对畜禽种类，不同生长阶段来选择预混料，应仔细验看标签上注明的畜种和适用阶段。

When purchasing premix, the products of regular manufacturers (Beijing Yinuo tianbang) should be preferred, and carefully check whether the packaging is standard and whether the label content is complete. The following items shall be indicated on the label: product name, application stage, main ingredients, type and content of drug additives, proportion of addition, instructions for use, production date, shelf life, executive standard, approval number, name, address and telephone number of the manufacturer. The sensory evaluation of the product quality should also be made. The qualified premix should have the same particle size, uniform color, and no peculiar smell, mildew, moisture absorption and caking. In the use of premix, the premix should be selected according to the type of livestock and poultry and different growth stages, and the species and applicable stage indicated on the label should be carefully checked.

4. 用量准确、混合均匀

4. Accurate dosage and even mixing

应按照说明与其它饲料充分混合饲喂，一般预混料用量占配合饲料总量的0.5%~6%，使用时应准确称量。因为用量过少达不到理想效果，用量过大不仅浪费，而且易引起中毒！ 预混料一定要与其它饲料充分混合均匀才能饲喂。并且更好随配随喂，配合好的饲料应用完。

It should be mixed with other feeds according to the instructions. The amount of premix should account for 0.5% ~ 6% of the total amount of compound feed. It should be weighed accurately when used. Because the dosage is too small to achieve the desired effect, too much dosage is not only a waste, but also easy to cause poisoning! The premix must be well mixed with other feeds before feeding. And the best with the feed, with a good feed should be used up in a day.

5.正确存放

5. Correct storage

注意掌握预混料的贮藏时间和条件，保持其新鲜。未开袋的预混料要存放在通风、干燥处；开袋后应尽快用完，切勿长时存放。使用期间应注意密封，避免潮湿，否则会导致有效成份含量降低。

Pay attention to the storage time and conditions of premix to keep it fresh. The unbacked premix should be stored in a ventilated and dry place; it should be used up as soon as possible after opening the bag, and should not be stored for a long time. Attention should be paid to sealing during use to avoid moisture, otherwise the content of active ingredients will be reduced.

总结：

Summary:

预混料是以动物生长发育及营养需要为理论依据，考虑多种相关因素的影响，采用的设备工艺，把多种维生素、微量元素、氨基酸及促生长因子等通过载体和稀释剂进行合理搭配、均匀混合而成的高科技产品。它包含了大部分的营养需要，与蛋白质、能量饲料混合后，可平衡地发挥营养作用，充分满足动物生长及生产的营养需要。所以，养殖户只有正确选购及合理使用预混料，才能充分发挥其的营养功能。

Premix is a high-tech product based on animal growth and nutrition needs, considering the influence of various related factors, adopting advanced equipment and technology, reasonably matching and evenly mixing various vitamins, trace elements, amino acids and growth promoting factors through carriers and diluents. It contains most of the nutritional needs. When mixed with protein and energy feed, it can play a balanced and efficient role in nutrition and fully meet the nutritional needs of animal growth and production. Therefore, only when farmers choose and use premix correctly, can they give full play to their nutritional function.
