Compound premix for pigs is an intermediate product made of a variety of feed additives according to a certain proportion, which aims to let users prepare full price feed by themselves. The standard of general terms for feed industry issued by China's Technical Supervision Bureau defines feed additives as follows: "a small amount or trace of nutritive or non nutritive substances added to feed to meet the special needs of livestock and poultry (such as improving feed utilization rate, ensuring or improving feed quality, promoting animal production and ensuring animal health).

一、飼料添加劑分類

1、 Classification of feed additives

飼料添加劑的分類眾說紛紜，不同學(xué)者提出不同分類方法，而筆者根據(jù)多年的基層實踐，認(rèn)為飼料添加劑分為以下三類更易為基層工作者所接受。

There are different opinions on the classification of feed additives, and different scholars put forward different classification methods. Based on years of grass-roots practice, the author thinks that feed additives can be divided into the following three categories, which are more easily accepted by grass-roots workers.

1、 營養(yǎng)性飼料添加劑

1. Nutritive feed additive

主要有氨基酸添加劑、維生素添加劑、礦物質(zhì)添加劑等。這類添加劑的用途是補(bǔ)充基礎(chǔ)日糧營養(yǎng)成分之不足，以使日糧達(dá)到營養(yǎng)成分平衡即全價性。

There are mainly amino acid additives, vitamin additives, mineral additives and so on. The purpose of this kind of additive is to supplement the deficiency of the basic diet nutrients, so as to make the diet reach the nutritional balance, that is, the total price.

2、 藥物飼料添加劑

2. Pharmaceutical feed additive

主要有抗生素添加劑、激素類添加劑、驅(qū)蟲劑、促長劑、生菌劑、中草藥添加劑等。國內(nèi)禁止使用激素類、劑類等用作飼料添加劑，絕不允許使用以提高肉豬瘦肉率為目的的β—興奮劑類。這類飼料添加劑的功效，主要在于增強(qiáng)機(jī)體免疫力，促進(jìn)生長，提高經(jīng)濟(jì)效益。歐盟對抗生素的使用有嚴(yán)格的規(guī)定，我國也禁止濫用，須嚴(yán)格按《飼料和飼料添加劑管理條例》執(zhí)行。

There are mainly antibiotic additives, hormone additives, anthelmintic agents, antibacterial growth promoting agents, microbial agents, Chinese herbal medicine additives and so on. It is forbidden to use hormones and tranquilizers as feed additives in China, and β - stimulants with the purpose of increasing lean meat rate of pigs are not allowed. The effect of this kind of feed additive is mainly to enhance immunity, promote growth and improve economic efficiency. There are strict regulations on the use of antibiotics in EU, and abuse of antibiotics is prohibited in China, which should be carried out in strict accordance with the regulations on Administration of feed and feed additives.

3、 改善飼料質(zhì)量添加劑

3. Additives for improving feed quality

主要有抗氧化劑、脂肪抑制劑、防霉劑、調(diào)味劑等。

There are mainly antioxidants, fat inhibitors, mildew inhibitors, seasoning agents and so on.

給豬供給全價飼料旨在提高畜禽飼料轉(zhuǎn)化率，這是廣大飼養(yǎng)者的愿望和要求。在能量和蛋白質(zhì)基本得到滿足的條件下，使用適量氨基酸、維生素、微量元素等添加劑即可完善配合飼料全價性，從而達(dá)到降低飼料消耗，提高生產(chǎn)水平和經(jīng)濟(jì)效益的目的。

The purpose of supplying pigs with full price feed is to improve the feed conversion rate of livestock and poultry, which is the desire and requirement of the majority of breeders. Under the condition that energy and protein are basically satisfied, the full price of compound feed can be improved by using proper amount of additives such as amino acids, vitamins and trace elements, so as to reduce feed consumption, improve production level and economic benefits.
