The basic method of pig feed identification: smell, touch, see, taste. Smell: Specific feed ingredients have their own unique aromatic odor. If there is odor, strange smell, mildew or odorless (admixed can mask the aromatic taste), the feed is a fake raw material. Touch: Because the human body is equipped with bio-electricity, it can be repeatedly inserted into the feed material by hand, and then shaken off. If the small substance is not easy to shake off, it means that there is a fake. Look: 1 color is consistent. The specific feed ingredients have their inherent luster. If there are different colors and different gloss in the same batch of raw materials, it means that there is a false; 2 whether the grain size is neat. Look at the finer-grained raw materials for the presence of finer fine particles or the presence of ultra-fine materials, and a certain amount. If there is a comparison between the damage and the specific raw materials, it is known. Taste: Specific ingredients have a fixed taste, such as sweet, sour, glutinous, bitter, fragrant, etc. If you taste it regularly, you will know the difference; especially stone powder, zeolite, sand and so on.
