Symptoms: In the early stage, symptoms include reduced appetite, pica, and a tendency to lie down. In the middle stage, affected pigs move stiffly, adopt an arched-back posture, and sway in the hindquarters; some develop lameness, with the hock joints of both hind legs sunken inward and splayed apart in a "V" shape. In the late stage, affected pigs lie down and do not walk, with both hind legs extended forward beside the abdomen and both forelegs bent beneath the chest. Most affected pigs have an oval-shaped cystic swelling below and behind the hock joint. Treatment: For severe cases, first disinfect the cystic swollen areas on both hock joints, then pierce them through with a three-edged needle and drain the contents. Then administer calcium gluconate by intravenous injection, 3 g per 50

Treatment: For severe cases, first disinfect the cystic swollen areas on both hock joints, then pierce them through with a three-edged needle and drain the contents. Then administer calcium gluconate by intravenous injection, 3 g per 50 kg of body weight, once a day; recovery can be achieved after 2 to 3 times. For early-to-middle-stage and mild cases, give calcium gluconate tablets orally at 2 g per 50 kg of body weight, twice a day, for 3 to 4 consecutive days.
