Best treatment for heat stress in pigs

The temperature is high in summer, and heat stress in pigs is a common problem, which has a great impact on farmers. Pig heat stress not only leads to prolonged sow labor, increased stillbirths, reduced lactation, lower conception rates and the number of live pigs born per litter, but also seriously weakens the pig herd's ability to resist disease. Below, I will introduce the best treatment plan for pig heat stress. Let’s take a look.

1. Symptoms of heat stress in pigs

When the temperature of the environment is high, the pigs will show irritability, loss of appetite, obvious thirst, and increased drinking, and then suddenly become ill. The sick pigs will be depressed or irritable, with rapid breathing, rapid heartbeat, conjunctival flushing, and body temperature up to 43°C. Some will foam at the mouth, vomit, have an unstable gait and cannot get up from the ground, and tremble all over. In severe cases, they are in a coma, and in acute cases, they may die.

1. Cooling

When pigs are experiencing heat stress and are gasping for breath, they should be moved to a cool place immediately. At this time, you can use cold water to pour on the pig's body, especially the head and neck, and use cold water to cool the stressed pig for 10-15 minutes. At the same time, you can provide some drinking water to the pigs. Add Dongxia Taibao to the drinking water so that the pigs can drink more of this drinking water. It contains vitamin C and mint , which can relieve the heat stress of the pigs and play a role in cooling down the pigs.

2. Bleeding at the tip of the ear

Bleeding the tips of pigs' ears can also have a cooling and calming effect. When pigs suffer from high fever, heat stress, heat stroke, or other serious breathing problems, bleeding from the tip of the ear is used as a treatment method. The place for bleeding from the pig's ear tip is usually about 2-5 cm from the tip of the pig's ear. Just cut a small hole with scissors . It is important not to bleed too much. Generally, 100-200 ml of blood is sufficient.

3. Relieve asthma in time

After cooling the pigs with cold water and bleeding the tips of their ears, the stress problem of the pigs can basically be alleviated. However, some pigs still have severe panting and difficulty breathing. At this time, aminophylline can be used to relieve the pigs' asthma. If some pigs are obviously weak and in a bad mental state, you can give them Kaishi Taibao at this time. Give it to the pigs by gavage, or mix it with water for them to drink. It can supplement the pigs with various amino acids, vitamins, etc., which can quickly restore the pigs' appetite and replenish the physical energy of the stressed pigs.

4. Scientific feeding

Heat stress has a great impact on sows' feed intake. To avoid the adverse effects of heat stress, you can feed wet mixed feed, adjust feeding time and increase feeding frequency, and implement the 7-3 feeding method, that is, feed 70% of the daily feeding amount in the morning and 30% of the daily feeding amount in the afternoon.

The above is the best treatment plan for heat stress in pigs. Once pigs suffer from heat stress, farmers must cool them down in time. Among them, water curtain cooling is the most common cooling measure used in pig farms in summer. When used in a closed pig house with wet curtains and fans, the temperature of the pen can be reduced by 5-8℃.
