Causes of respiratory diseases in pigs

The most troublesome problem for pig farmers is the occurrence of various diseases, which are very disadvantageous to the growth and development of pigs, especially respiratory diseases, which will affect the appetite of pigs and cause the slow growth rate of pigs and the inability to gain fat normally. seriously reduce the commodity value, but also have an impact on the economic interests of farmers. What is the cause of respiratory disease? Let's take a look at it.

1. Bacterial infection

The emergence of a large number of respiratory diseases in pigs is likely to be due to the infection of bacteria in the respiratory tract of pigs, resulting in mycoplasma pneumonia, which usually invades the body of piglets when they are weaned and nursed, or even during the fattening period. this kind of bacteria is difficult to defend. Not only mycoplasma pneumonia, but also porcine lung disease, Haemophilus and other bacteria are also the causes of respiratory diseases in pigs. Therefore, special attention should be paid to the hygiene of pig houses and the elimination of germs in spring.

2. Viral infection

Viral infection usually occurs in winter, because there is a large temperature difference between day and night in winter, which makes pigs easy to produce influenza virus, which is difficult to control once it begins to spread. Epidemic transmission is extremely strong, but the cycle of the disease is short and not long, so it is relatively easy to treat. However, according to the situation, if you are infected with pseudorabies and other acute viruses, the virus spreads very fast, treatment is very difficult, and the mortality rate is very high.

3. Parasite infection

Parasite infection usually occurs in summer, because it is high-temperature, rainy, wet and hot in summer. if the environment in the piggery is not controlled, poor permeability leads to an increase in temperature in the injection and turbid air. This kind of environment is the most favorite environment for parasites, and it is also the most suitable for parasite breeding. Parasites can infect pigs so that they become thinner and unable to gain weight. If it is found that there are eggs in pig feces, it can be identified as parasitic infection.

4. Environmental infection

As mentioned earlier, if the environment of the pig house is too poor, the air is not ventilated, the space is closed, and if the pig house is not ventilated in time, pigs will be very vulnerable to respiratory diseases. For example, if there is too much carbon dioxide in the air, the inhalation of the pig will cause the respiratory tract of the pig to produce mucous membrane, resulting in respiratory diseases. Therefore, it is necessary to disinfect the pig house regularly, maintain the permeability of the pig house, clean up pig manure in time, and give the pig a good living environment.

The above are the four causes of respiratory diseases in pigs, summed up in the end or due to environmental reasons, as well as temperature and humidity, weather and so on. Therefore, the pigsty must be cleaned regularly to prevent the breeding of various germs and parasites. For more information, please continue to follow the pro-agricultural network!
