1、 Different stages of premix should be selected according to the growth status of pigs.

普通从猪出生七天开端到出栏上市，针对性的选择教槽料、保育料、小猪料、中猪料、大猪料等。母猪普通视怀孕状况可选择怀孕母猪料、哺乳母猪料，公猪一 般用大猪或公猪料。但有时可在畜牧师或兽医师的指导下选择不同的饲料品种。

Generally, from seven days after birth to the market, the selection of pig feed, nursery feed, piglet feed, medium pig feed, large pig feed, etc. According to the pregnancy status, sows can choose pregnant sow feed and lactating sow feed, while boars generally use large pig or boar feed. But sometimes different feed varieties can be selected under the guidance of animal husbandry or veterinary doctors.

二、综合判别饲料质量的优劣。

2、 To judge the quality of feed comprehensively.

1、从市场反应状况来看某种预混料能否怨声载道，能否稳定，上市时间有多长。普通时间越早，在市场上较稳定或有开展趋向的饲料是较好的饲料。

1. Judging from the market reaction, whether a certain premix can be complained about, whether it can be stable, and how long it will be on the market. The earlier the normal time is, the better feed is the more stable or developing trend in the market.

2、从饲料厂家的实力以及售后效劳状况来看所选择的饲料，普通实力较强的厂家消费的饲料稳定，售后效劳好的厂家消费的饲料被选择养殖时有一定的保证，能够共同开展，共同促进。

2. From the strength of feed manufacturers and after-sales service status, the selected feed is stable for ordinary strong manufacturers, and certain guarantee is provided for feed consumption by manufacturers with good after-sales service, which can be jointly carried out and promoted.

3、饲料的价钱以及包装来看选择饲料。在市场竞争剧烈的状况下，价钱较廉价的料不一定是质量较好。普通好的饲料包装相对较好，印字明晰，标签有证有号，有细致的出厂日期、消费批次、运用阐明等。包装袋上有明白的联络电话、厂家、效劳承诺等。

3. Feed price and packaging to see the choice of feed. In the fierce market competition, the cheaper materials are not necessarily of better quality. The ordinary and good feed packaging is relatively good, with clear printing characters, labels with certificates and numbers, and detailed factory date, consumption batch, and application explanation. There are clear contact number, manufacturer and service commitment on the package.

三、目前市场上存在的几点运用预混料的误区。

3、 At present, there are some misunderstandings in the use of premix in the market.

1、单一从猪粪的颜色，软硬来判别饲料的“好坏”。猪粪颜色较深，不一定代表猪的消化良好，一种铜含量较高的饲料惹起的猪粪，颜色普通是较黑 的。饲料中 含有丰厚的保健药物时，猪粪颜色有时会浅。猪的消化状况，预混料以及其它饲料原料的品种及搭配等都会影响猪粪的颜色及软硬。普通较正常粪便应是不干不稀， 不恶臭(但有时有氨气息)，没有异物。

1. Single from the color of pig manure, soft and hard to judge the feed "good or bad". The color of pig manure is darker, which does not necessarily mean that the pig has good digestion. Pig manure caused by a high copper content feed is usually darker. When the feed contains rich health care drugs, the color of pig manure sometimes will be light. The color and hardness of pig manure can be affected by the digestion of pig, the variety and collocation of premix and other feed materials. Common more normal feces should be not dry, not thin, no odor (but sometimes with ammonia breath), no foreign matter.

2、单一从猪的皮毛外观来判别饲料的“好坏”。

2. The "good or bad" of feed can be judged only from the appearance of pig fur.

3、呈现普通性疾病时，误以为是由饲料惹起的。猪在饲养过程中由于环境、猪种、饲养状况等不同要素会引发不同的疾病，很少会由饲料直接引疾病。 普通由饲料惹起的疾病及异常状况有中毒、 食欲忽然改动等。发霉的饲料有时会惹起猪的腹泻，饲料的改动有时会惹起其猪食欲的改动。

3. When presenting common diseases, they mistakenly thought it was caused by feed. In the process of raising pigs, due to different factors such as environment, pig species, feeding conditions, etc., different diseases will be caused by different feed. Common diseases and abnormal conditions caused by feed poisoning, sudden changes in appetite, etc. Moldy feed sometimes causes diarrhea in pigs, and changes in feed sometimes cause changes in pig appetite.

4、单一从饲料的香味判别质量。普通的饲料为增加猪的食欲会参加一定的香味剂，但不一定很香的饲料就是猪喜欢吃的。猪普通喜欢奶香味、鱼腥味、草莓味等。有的厂家为惹起客户留意而参加较多的香味剂，只是增加了饲料的无效本钱。

4. The quality of feed was judged by the flavor of feed. In order to increase the appetite of pigs, ordinary feed will participate in certain flavoring agents, but not necessarily very fragrant feed is what pigs like to eat. Pigs generally like milk flavor, fishy smell, strawberry flavor and so on. In order to arouse the attention of customers, some manufacturers participate in more flavoring agents, which only increase the invalid cost of feed.

5、混杂预混料所针对的猪生长阶段以及在恣意参加别的饲料原料。例如用中猪预混料喂小猪，喂大猪。这样的喂法不能发挥猪的较大生长潜能，还增加饲 料本钱。用4%预混料参加盐、或骨粉等，看来似乎加了营养，但是过多参加食盐可惹起蓄积轻度中毒。额外参加饲料原料反而降低养殖利润，不过有时在正 确指引的状况下参加适宜的其它物质是有效的补充。如调整性地参加药物，碎青草等。

5. The hybrid premix is aimed at the growth stage of pigs and is free to participate in other feed ingredients. For example, pig premix is used to feed piglets and big pigs. This kind of feeding method can not give full play to the growth potential of pigs, but also increase the cost of feed. Adding 4% premix to salt or bone meal seems to have added nutrition, but too much salt can cause accumulation of mild poisoning. Additional feed ingredients can reduce the breeding profit, but sometimes it is an effective supplement to take part in other suitable substances under the correct guidance. Such as adjusting to participate in drugs, broken grass and so on.

6、过火追求猪的体型、出栏价钱，致使运用有兴奋剂或其它添加剂的大猪料，这给社会带来了一定的不良影响。在国度制止的状况下，又是一种不合理行为。用平安、的高质量饲料才是养殖追求的目的。

6. The excessive pursuit of pig's body shape and price leads to the use of pig feed with stimulants or other additives, which has brought certain adverse effects to the society. In the state to stop the situation, it is an unreasonable behavior. Safe and environmental protection of high quality feed is the goal of breeding.
