If it is faded, it may be caused by allergies or pig erysipelas. If there is red bleeding on the skin, the pressure will not fade, then you can have a pig.瘟, streptococcosis, etc.
Look at the eyes: Healthy pig eyes are bright and bright, and the conjunctiva is pink. If the conjunctiva is pale, it may have some blood disease or malnutrition; if the conjunctiva is flushed, the eyelids are more, indicating that the body temperature is too high, may have some kind of inflammatory disease; if the conjunctival cyanosis (blue-violet), it may suffer In the toxic disease, or in the later stages of the infectious disease, the blood circulation has an obstacle; if the eyelids are edematous and before and after weaning, there may be a piglet edema disease.

If the pig's nose is found to be dry or even cracked, it may have a high body temperature, lack of drinking water, or some inflammatory disease, or an infectious disease; if there is septic or purulent nasal fluid in the nose, it may have a cold, or Upper respiratory tract disease; if a nasal nostril flows out of purulent nasal fluid and the face is rubbed to one side, it may have infectious atrophic rhinitis.
