What causes abdominal breathing in pigs?
So this is what causes abdominal breathing in pigs!
Porcine infectious pleurisy
Porcine infectious pleurisy is caused by a common respiratory infectious disease, whose lesions mainly manifest as pneumonia and pleurisy. The disease causes severe breathing difficulty in pigs, leading to abdominal breathing, and can even cause acute septicemia and sudden death.
Porcine infectious pleuropneumonia
1. Porcine infectious pleuropneumonia of the most acute type has a sudden onset, causing an increase in body temperature, an increased heart rate, listlessness, and loss of appetite, followed by diarrhea and vomiting, though these do not last long.
2. Although early-stage affected pigs show no obvious respiratory symptoms, in the later stage of porcine infectious pleuropneumonia, heart failure occurs, with cyanosis of the nose, ears, eyes and skin of the hindquarters, leading to extreme breathing difficulty in the late stage, open-mouth tongue protrusion, coughing and wheezing, and abdominal breathing. Before death, body temperature drops, and in severe cases, foamy bloody discharge flows from the mouth and nose.
3. Pigs with porcine infectious pleuropneumonia mostly die within 24-36 h after symptoms appear, with a mortality rate as high as 80%-100%.
2. Choose according to different situationsTreatmentmethods
TreatmentPorcine infectious pleurisy: the drugs of first choice are generally penicillin, chloramphenicol and sulfamethoxazole-trimethoprim (Sinomin). For the firsttreatmentinjection must be chosen,treatmentthe dose should be slightly larger; if combined with addition to feed and drinking water, the effect is better.
Note: Do not use chloramphenicol for too long; when administering Sinomin orally, it should be combined with an equal amount of sodium bicarbonate (baking soda); long-acting oxytetracycline, Dexamycin, etc. may also be chosen.
Treatmentinfectious pleuropneumonia: choose florfenicol by intramuscular injection or thoracic cavity injection for more than 3 consecutive days; mix tiamulin, doxycycline, florfenicol or kitasamycin into the feed for 5-7 consecutive days, which has a relatively good effect.
Note: If conditions permit, it is best to conduct a drug sensitivity test and choose sensitive drugs fortreatment; antibiotictreatment, although it has achieved certain clinical success, cannot eliminate the infection in the pig herd.
If a pig shows abdominal breathing but its body temperature is normal
treatmentprinciple: for pigs with this condition, the disease is chronic, the course is long, and the pig's constitution is poor, so it is not suitable to choose drugs with strong side effects such as tilmicosin, because the target organ of tilmicosin's toxic side effects is the heart, which can cause tachycardia and weakened contractility, and very easily lead to death after injection in pigs.
Lincomycin and other mild sensitive antibiotics plus dexamethasone can be chosen to prevent shock, while aminophylline is used on the other side to relieve asthma, treating both the symptoms and the root cause. Inject lincomycin (10mg/kg) + dexamethasone (1mg/15kg) intramuscularly on one side, and inject aminophylline (0.5g per dose) intramuscularly on the other side, once in the morning and once in the afternoon, for 2-3 consecutive days, with the dexamethasone dose halved on the second day.
If a pig shows asthma, coughing, and fever
treatmentprinciple: use mild antipyretic drugs such as Shuanghuanglian and flunixin meglumine, and try not to use aminopyrine or analgin, because forced fever reduction causes a sudden drop in temperature and shock death; at the same time, combine with sensitive antibiotics fortreatment。
Inject florfenicol or lincomycin or tilmicosin + Shuanghuanglian intramuscularly on one side, and aminophylline (0.5g per dose) on the other side.
Medication precautions
1. Dexamethasone and aminophylline have a short duration of effect, so when used they must be given once in the morning and once in the afternoon for 2-3 consecutive days, until the pig's breathing returns to normal.
2. Aminophylline has a good asthma-relieving effect, and when combined with antibiotics it can effectively control wheezing, but when used together with lincomycin, it can reduce its clearance rate in the liver, raise the blood drug concentration, and even cause toxic reactions. Strictly control the dose when using it, 0.25-0.5g per dose for pigs.
3. Dexamethasonetreatmentfor abdominal breathing can effectively absorb inflammatory secretions in the lungs, keeping the pig's respiratory tract unobstructed. The dexamethasone dose should be gradually reduced, while the antibiotic dose remains unchanged, until the inflammation disappears, to prevent recurrence of the condition.
