In pig production, in order to prevent the occurrence of disease, many large-scale pig farms and farmers will add some drugs to pig feed, but when adding drugs to pig feed, the following five aspects should be paid attention to.

一、在添加藥物的時(shí)候，應(yīng)根據(jù)生豬的年齡以及生長(zhǎng)階段進(jìn)行針對(duì)性的投藥。對(duì)于體質(zhì)較弱的生豬以及母豬應(yīng)選擇敏感性比較小并且毒性小、用量少的藥物，在配合飼料中應(yīng)該添加容易被腸道吸收的藥物，青霉素等容易被消化液破壞的藥物不適合添加。

1、 When adding drugs, it should be targeted according to the age and growth stage of pigs. For pigs and sows with weak physique, drugs with low sensitivity, low toxicity and low dosage should be selected. Antibacterial drugs that are easy to be absorbed by intestinal tract should be added in the formulated feed. Drugs that are easy to be destroyed by digestive juice such as penicillin are not suitable to be added.

二、在豬飼料中添加藥物的時(shí)候，應(yīng)分辨藥品的真假，一些沒(méi)有商標(biāo)、批準(zhǔn)文號(hào)以及過(guò)期的藥物不能購(gòu)買和添加，同時(shí)要注意，不要一次購(gòu)入太多的藥物，現(xiàn)購(gòu)現(xiàn)用。

2、 When adding drugs to pig feed, it is necessary to distinguish the authenticity of drugs. Some medicines without trademarks, approval numbers and expired drugs can not be purchased and added. At the same time, it should be noted that too many drugs should not be purchased at one time, and they should be purchased and used now.

三、添加藥物的時(shí)候，如果一種藥物就可以發(fā)揮作用，就不要添加多種藥物，如果需要添加多種藥物，要注意配伍禁忌。

3、 When adding drugs, if one drug can play a role, do not add multiple drugs. If you need to add multiple drugs, you should pay attention to incompatibility.

四、藥物的添加劑量根據(jù)生豬的個(gè)體差異進(jìn)行確定，如果是預(yù)防用藥，只需要添加用量的四分之一就可以了，如果藥物的殘留比較明顯，要禁止使用。

4、 The addition dose of drugs is determined according to the individual differences of pigs. If it is preventive medicine, only one fourth of the treatment dosage is needed. If the drug residue is obvious, it should be prohibited to use.

在豬飼料中添加藥物的時(shí)候，應(yīng)將飼料與藥物攪拌均勻，避免生豬誤食過(guò)多導(dǎo)致中毒，添加藥物的飼料要現(xiàn)配先用，不能放置太長(zhǎng)時(shí)間。

When adding drugs to pig feed, the feed and drug should be mixed evenly to avoid poisoning caused by excessive ingestion of pig. The feed added with medicine should be used immediately and should not be placed for too long.
