Causes and treatments of pig coughing in winter

With the arrival of winter, the temperature drops and the ground freezes, making pigs more susceptible to respiratory diseases such as coughing and difficulty breathing. Farmers must take preventive measures in advance and immediately diagnose and treat any abnormal symptoms in pigs to ensure the health of the pigs and breeding benefits.

1. Causes of pig coughing and wheezing in winter

Tips for identifying coughing and dyspnea in pigs: Frequent coughing during the day and less at night usually indicates bronchitis or pneumonia; more coughing at night and less coughing during the day may indicate tuberculosis or heart failure; more obvious coughing in the morning is common in inflammation of the larynx, trachea and upper respiratory tract; paroxysmal coughing, which worsens during eating, may be caused by foreign objects blocking the airway; intermittent coughing, accompanied by teeth grinding during sleep, may be related to lung filariasis.

Tip 2 for identifying coughing and dyspnea in pigs: Frequent and continuous coughing is common in acute laryngitis, bronchitis, and pneumonia; occasional coughing one or two times may be related to colds, chronic bronchitis, and pharyngitis; occasional strong coughing may be foreign body pneumonia; continuous and spasmodic coughing is more common in the late stage of laryngitis or asthma.

In addition, the duration of the cough is also important. Acute sudden cough usually has a short course, no more than a few weeks, and may be caused by pulmonary congestion, pulmonary edema, pericarditis or pericardial effusion; chronic cough has a longer course and is common in chronic pharyngitis, bronchitis, and tuberculosis.

If the cough is accompanied by other symptoms, such as coughing up blood (a small amount is more common in tracheitis and pneumonia, a large amount may be pulmonary cavitation), difficulty breathing (difficulty in exhalation is common in Pasteurella infection, difficulty in inhalation may be related to alveolar and bronchitis, and combined difficulty in breathing is common in pleurisy and pneumonia).

Combining the actual situation of the pig farm and the above common symptoms, an accurate diagnosis can be made and appropriate drugs can be selected for prevention and treatment, including mixing with feed, drinking water or injection. The method of administration is determined according to the urgency and severity of the disease.

2. Treatment of pig cough and asthma in winter

1. Prevention is the key to controlling such diseases.

When raising pigs in autumn and winter, ensure that the pig house has proper winter protection measures and is ventilated to maintain a good environment.

Clean the feces in the pig pen regularly and implement disinfection measures as needed to prevent the growth of bacteria and viruses.

Develop and implement appropriate vaccination programs based on the health status of the pig herd to prevent porcine respiratory diseases and pleuropneumonia, etc.

2. Once sick pigs are found, measures should be taken quickly to control them.

For pigs' coughing and breathing difficulties, you can use Qingfei Zhike Powder, which can be mixed with feed and given for 3 to 5 consecutive days. For seriously ill pigs, the dosage can be increased appropriately.

In addition, 0.1 to 0.2 ml of florfenicol injection can be used, 1 to 2 times a day, for 2 to 3 consecutive days. This method is suitable for treating cough and breathing difficulties associated with lung infections.

In short, the emergence of pig respiratory diseases does not happen overnight and is usually caused by poor implementation of feeding and management measures. Especially in cold seasons, while farmers try to keep the pig house warm, they often overlook the importance of ventilation, which may lead to excessive concentrations of harmful gases such as ammonia and odor in the pig house, thereby irritating the pigs' respiratory organs and causing abnormal reactions. Mild symptoms may include coughing and wheezing, while severe ones may lead to other diseases.
