What are the causes of respiratory diseases in pigs?
The biggest headache for pig farmers is the occurrence of various diseases. The occurrence of diseases is very detrimental to the growth and development of pigs, especially respiratory diseases. Respiratory diseases affect the appetite of pigs, causing slow growth, preventing them from gaining weight normally, severely reducing their commercial value, and also affecting the economic interests of farmers. So what are the causes of respiratory diseases? Let's take a look below!
1. Bacterial infection
A large number of respiratory diseases in pigs is very likely because the pig's respiratory tract is infected with bacteria, leading to mycoplasma pneumonia. This mycoplasma bacterium generally invades the piglet's body at weaning and nursery stages, and can even invade during the fattening period. This bacterium is very difficult to defend against. Not only mycoplasma pneumonia, but also swine pasteurellosis, haemophilus and other bacteria are causes of respiratory diseases in pigs. Therefore, in spring, special attention should be paid to pigsty hygiene and eliminating bacteria.
2. Viral infection
Viral infection generally occurs in winter, because the temperature difference between day and night in winter is large, making pigs very susceptible to influenza-type viruses. Once the influenza virus begins to spread, it is very difficult to control. It is extremely contagious, but the cycle of this disease is short and the duration is not long, so it is relatively easy to treat. However, it depends on the situation. If infected with acute viruses such as pseudorabies, this virus spreads extremely fast, treatment is very difficult, and the mortality rate is extremely high.
3. Parasitic infection
Parasitic infection generally occurs in summer, because summer is hot and rainy, both wet and hot. If the environment inside the pigsty is not properly controlled, poor ventilation leads to increased temperature inside the pigsty and turbid air. This environment is the favorite environment for parasites, and it is also the most suitable for parasites to breed and reproduce. Parasites will parasitize the pig's body, making the pig increasingly emaciated and unable to gain weight. If worm eggs are found in pig manure, it can be confirmed as parasitic infection.
4. Environmental infection
As mentioned earlier, if the pigsty environment is too poor, the air is not circulating, the space is enclosed, and ventilation and air exchange are not carried out in time, pigs will be highly susceptible to respiratory diseases. For example, if the carbon dioxide content in the air is too high and pigs inhale it, it will cause mucous membranes in the pig's respiratory tract, leading to respiratory diseases. Therefore, the pigsty should be disinfected regularly, maintain ventilation, clean up pig manure in time, and give pigs a good living environment.
The above are the four causes of respiratory diseases in pigs. In summary, it still comes down to environmental reasons, as well as temperature, humidity, weather, etc. Therefore, the pigsty must be cleaned regularly to prevent the breeding of various bacteria and parasites.
