1. Only from the color of pig manure, soft and hard to judge the "quality" of feed. The color of pig manure is darker, which does not necessarily mean that the pig digests well. The color of pig manure caused by a feed with high copper content is generally darker. When the feed contains rich health care drugs, the color of pig manure is sometimes light. Pig digestion, pig premix and other feed materials will affect the color and hardness of pig manure. Generally speaking, the normal feces should not be dry or thin, odorless (but sometimes with ammonia smell), and free of foreign matters.

2、单一从猪的皮毛外观来判断饲料的“好坏”。

2. Only from the appearance of pig fur to judge the "quality" of feed.

3、出现一般性疾病时，误认为是由饲料引起的。猪在饲养过程中由于环境、猪种、饲养情况等不同因素会引发不同的疾病，很少会由饲料直接引疾病。一般由饲料引起的疾病及异常情况有中毒、食欲突然改变等。发霉的饲料有时会引起猪的腹泻，饲料的改变有时会引起其猪食欲的改变。

3. When a general disease occurs, it is mistakenly thought to be caused by feed. In the process of raising pigs, due to different factors such as environment, pig species, feeding conditions and so on, different diseases will be caused, rarely directly caused by feed. Generally, diseases and abnormalities caused by feed include poisoning, sudden change of appetite, etc. Moldy feed sometimes causes diarrhea in pigs, and the change of feed sometimes causes the change of appetite in pigs.

4、单一从饲料的香味判断质量。一般的饲料为增加猪的食欲会加入一定的香味剂，但不一定很香的饲料就是猪喜欢吃的。猪一般喜欢奶香味、鱼腥味、草莓味等。有的厂家为引起客户注意而加入较多的香味剂，只是增加了饲料的无效成本。

4. Only judging the quality from the flavor of feed. General feed to increase the appetite of pigs will be added with certain flavor agents, but not necessarily very fragrant feed is what pigs like to eat. Pigs generally like milk, fishy, strawberry and so on. In order to attract customers' attention, some manufacturers add more flavor agents, which only increases the invalid cost of feed.

5、大猪预混料所针对的猪生长阶段以及在任意加入别的饲料网饲料原料。例如用中猪猪预混料喂小猪，喂大猪。这样的喂法不能发饲料挥猪的生长潜能，还增加饲料成本。用4%猪预混料加入盐、或骨粉等，看来似乎加了营养，但是过多加入食盐可引起蓄积轻度中毒。额外加入饲料原料反而降低养殖利润，不过有时在正确指引的情况下加入合适的其它物质是有效的补充。如调整性地加入药物，碎青草等。

5. Large pig premix is aimed at pig growth stage and other feed net feed materials are added at will. For example, feed small pigs and big pigs with pig premix. This feeding method can not develop the maximum growth potential of Chinese feed volatilized pigs, but also increase feed cost. Adding salt or bone meal with 4% pig premix seems to add nutrition, but adding too much salt can cause accumulation of mild poisoning. The addition of feed materials will reduce the profits of breeding, but sometimes it is effective to add other materials under the correct guidance. Such as adjusting to add drugs, broken grass and so on.

6、过分追求猪的体型、出栏，以致使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。在禁止的情况下，又是一种不正当行为。用、的高品质饲料才是养殖追求的目标。

6. The excessive pursuit of pig's body shape and market price leads to the use of large pig feed with stimulants or other additives, which has brought certain adverse effects to the society. In the case of state prohibition, it is also an improper act. Using safe and environmental protection high quality feed is the goal of breeding.
