How to observe sick pigs? Master these methods to detect pig diseases early

Check the demeanor. Healthy pigs are spirited, with tails raised and swinging freely; sick pigs are listless, move slowly, prefer to lie still, and have drooping tails.

Check the appetite. Healthy pigs have a strong appetite; sick pigs show a sudden loss of appetite, abnormal eating habits, or even stop eating. If a pig's appetite decreases and it drinks a lot of water, it is mostly a febrile disease.

Check nasal discharge. Healthy pigs have no nasal discharge; if a pig has clear nasal discharge, it is mostly a wind-cold cold, thick and sticky nasal discharge indicates heat in the lungs, and nasal discharge containing foam indicates diseases such as pulmonary edema or chronic bronchitis.

Check the feces. Healthy pig feces are soft and moist, cone-shaped, and have no unusual odor; if a pig's feces are dry and hard and small in amount, it is mostly a febrile disease; if a pig's feces are thin like water or muddy, with a marked increase in defecation frequency or fecal incontinence, it is mostly enteritis or intestinal parasite infection; if piglets pass grayish-white, grayish-yellow, or yellow-green watery feces with a fishy odor, it is mostly infectious diseases such as white scour, swine fever, swine erysipelas, or swine lung disease, and the feces often contain mucus, pus, or blood.

Check the sleeping posture. Healthy pigs generally sleep on their sides, with relaxed muscles and even breathing; sick pigs often press their whole body against the ground, lying prone in exhaustion, and if breathing is difficult, they will sit like a dog.
