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、單一從豬的皮毛外觀來判斷飼料的“好壞”。

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

3、出現(xiàn)一般性疾病時，誤認為是由飼料引起的。豬在飼養(yǎng)過程中由于環(huán)境、豬種、飼養(yǎng)情況等不同因素會引發(fā)不同的疾病，很少會由飼料直接引疾病。一般由飼料引起的疾病及異常情況有中毒、食欲突然改變等。發(fā)霉的飼料有時會引起豬的腹瀉，飼料的改變有時會引起其豬食欲的改變。

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、單一從飼料的香味判斷質(zhì)量。一般的飼料為增加豬的食欲會加入一定的香味劑，但不一定很香的飼料就是豬喜歡吃的。豬一般喜歡奶香味、魚腥味、草莓味等。有的廠家為引起客戶注意而加入較多的香味劑，只是增加了飼料的無效成本。

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、大豬預混料所針對的豬生長階段以及在任意加入別的飼料網(wǎng)飼料原料。例如用中豬豬預混料喂小豬，喂大豬。這樣的喂法不能發(fā)飼料揮豬的生長潛能，還增加飼料成本。用4%豬預混料加入鹽、或骨粉等，看來似乎加了營養(yǎng)，但是過多加入食鹽可引起蓄積輕度中毒。額外加入飼料原料反而降低養(yǎng)殖利潤，不過有時在正確指引的情況下加入合適的其它物質(zhì)是有效的補充。如調(diào)整性地加入藥物，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、過分追求豬的體型、出欄，以致使用有興奮劑或其它添加劑的大豬料，這給社會帶來了一定的不良影響。在禁止的情況下，又是一種不正當行為。用、的高品質(zhì)飼料才是養(yǎng)殖追求的目標。

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.
