1. The pig is lame because Streptococcus dare not stand.
The sick pig's leg is swollen, the pig limps or can't get up on the ground. Ordinary pigs crawl on the ground with their forelimbs without any symptoms of wheezing and coughing.
Targeted treatment: for pigs with swollen joints: strong amoxicillin+dexamethasone+flunixin meglumine, mixed intramuscular injection; Pigs with neurological symptoms: sulfamethoxazole and trimethoprim should be used twice for the first time. Because Streptococcus suis is prone to drug resistance, the dosage should be sufficient and the course of treatment should be sufficient. The methods of rotation and combined medication can be considered.
2. Leg lameness in pigs caused by Haemophilus parasuis.
Sick pigs are characterized by limping, difficulty in standing and even paralysis. In addition, the sick pigs have symptoms of asthma and cough, and the joints in the affected parts of the legs are swollen. If sick pigs are not effectively treated, the mortality rate is very high.
Specific treatment: individualized injection: immediate isolation, Qingkailing injection+enrofloxacin injection+ampicillin intramuscular injection; For pigs with severe joint swelling: intramuscular injection of cefotaxime+flunixin.
The pig is lame, because erysipelas dare not stand.
Chronic cases of erysipelas are mainly arthritis. Arthritis can invade one or more joints, mainly in the ankle joint, knee joint and wrist joint of the hind limbs of suckling pigs (also seen in fattening pigs). These pigs have poor appetite, stiff bodies, a limp and are unwilling to move. In order to relieve pain, the body's center of gravity often shifts from one leg to the other, and the limbs may contract below the abdomen. Take a hunched posture, unwilling to stand or unable to stand at all.
4. Pigs suffer from hoof disease, lack of trace elements, or the ground of the enclosure is too smooth, which is easy to cause hoof disease. Pigs can't stand up because their hooves are inflamed and painful. It is suggested that the wound should be disinfected and treated with fish fat. In addition, clean soil can be put in the pen, which is also helpful for the recovery of sick pigs.
Treatment: The sensitive drugs of erysipelas are penicillins and cephalosporins. You can choose to inject ceftiofur or enrofloxacin at the early stage of the disease, and add compound amoxicillin to the feed or drinking water of sick pigs for prevention and treatment.
