What to Do If a Sow Has a Persistent High Fever After Farrowing? Detailed Explanation of Causes and Treatment Methods

In some pig farms, after a sow gives birth, symptoms such as persistent high fever, rapid breathing, reduced milk production, and limb paralysis may appear. So what should be done if a sow has a persistent high fever after farrowing?

1. What to do if a sow has a persistent high fever after farrowing?

If a sow has a persistent high fever after farrowing, it is necessary to adjust nutrition, clear heat and remove toxins, and improve feeding conditions. The following measures can be taken:

1. Quickly move the pig to a shady, well-ventilated place.

2. Bleed the ear tips and tail of the sick pig to promote blood circulation.

3. Apply baijiu to the udder and hairless areas for external physical cooling.

4. First use 500 ml of normal saline plus 6 vials of cefradine, then use 400 ml of 5% glucose solution plus 6 vials of Qingwen Baidu injection for intravenous drip.

5. Intramuscular injection of 10% vitamin C, oral rehydration salts for free drinking water, for three consecutive days.

2. Causes of the disease

1. Extensive feeding management, without increasing or decreasing feed according to nutritional requirements

During the early, middle, and late stages of pregnancy, pigs should be supplied with different feeds according to different nutritional standards. However, most rural farmers, in order to reduce costs, add little or no sow concentrate during the sow's pregnancy, and instead use large amounts of distillers' grains, rice bran, rice husk powder, and a small amount of corn with lower nutritional value to maintain life, resulting in an imbalance of protein and energy and causing nutritional deficiency. Before farrowing and after farrowing, they then feed large amounts of energy feed in a concentrated way, resulting in postpartum collapse of the sow, insufficient blood glucose and blood calcium, and decreased immunity, making the sow prone to this disease.

2. Improper environmental management, poor ventilation

In summer and autumn, heat prevention and cooling work in rural areas is not in place, and the temperature inside the pig house is high. There is also the habit of giving little water during farrowing and not ventilating for fear that the pig will "catch wind." When farrowing occurs at high temperatures, the sow produces a large amount of heat that cannot be dissipated. Due to poor ventilation, ammonia gas in the pig house increases, air quality is poor, and oxygen supply is insufficient, which most easily causes postpartum diseases in sows.

3. Lack of preventive medication

In the period before farrowing, preventive medication should be given according to the patterns of disease occurrence. Generally, after farrowing, pigs are most prone to conditions such as not eating and fever, and timely medication can reduce the occurrence of such diseases.

After farrowing, sows should receive attention to nutritional management and hygiene management to ensure the sow's health and allow the piglets to grow better.
