African swine fever is a disease that causes many deaths in pigs worldwide. This disease spreads very quickly.
Symptoms of the disease
This disease attacks and disrupts the circulatory system, digestive tract and respiratory tract. You can see its symptoms from five to fifteen days. If the disease is very severe, pigs can die even before the disease is visible.
The immediate symptoms are that the pig loses its appetite and develops a high fever. Fortunately, the pig farmer can detect sudden deaths in his pigs. In those pigs that are lucky enough to recover, the virus remains in their bodies and can come out and attack healthy ones.
An infected pig’s body temperature rises from 38.3 to 40 degrees Celsius or more. Its skin becomes slightly red due to the fever. The result of a severe attack is that the pig can die after six to twenty days. Interestingly, the temperature caused by the fever drops significantly in the first or fifth day before the pig dies.
If the infection is not severe, it is possible that at least half of the pigs will die, however, those who survive will carry the virus in their bodies for up to six months. Infected pigs may show the following symptoms:-
.Lack of energy
. Heavy bleeding
. Difficulty breathing
. Frequent sleepiness
. Nose is covered with blood and foam
. Frequent vomiting
. Discoloration of various parts of the body
. Frequent coughing
. The croup is covered with blood
. Blood
. The back of the lungs is covered with blood
. Red patches on the lower parts of the body up to the skin
. Red fluid has spread to the heart
. Black blood patches on the legs
. The large intestine is filled with red ulcers and ulcers
. The urinary bladder is covered with white membrane
. The lining of the stomach is red
Postmortem signs
After examination by a veterinarian the following are found
: . Fluid accumulation in the abdominal cavity
. Fever-like lesions caused by diseases such as salmonellas, erysipelas and other toxins
. Blood clots and other blood-borne lesions
. Lesions caused by and typical of swine fever
The most affected areas by swine flu are;
. The skin, especially around the ears, nose, stomach and anus
. The abdomen can swell to twice its normal size
. The lungs become fluid-filled with pneumonia or pneumonia
. The kidneys bleed in small areas or throughout the body
. Fluid accumulation can be seen in the cavities in other parts of the body or in the joints sometimes this disease causes sudden death even if symptoms of the lesions do not appear .
Lymph nodes in the form of clotted blood
The viruses that cause this disease are as follows:
When swine flu occurs, the effects spread very quickly. Its source is pigs that are already infected. In severe cases, the virus of this disease is shed in the feces, urine and sweat of the infected pig.
The virus can survive in such dirt for a long time. The virus can also survive in stored meat for about 150 days.
It should be noted that wild pigs and wild boars can carry this virus in their bodies even if they do not show any signs of being infected. However, if the virus finds a way in, it can spread to domestic pigs.
Transmission can occur through: –
.Carcasses that have been disposed of in a haphazard manner
.Through infected animals .Through
ticks that carry the virus .Contact
between infected and uninfected pigs
.Through inanimate objects such as shoes, clothing, equipment and vehicles
.Through wild animals that carry the virus
Steps to control this disease
The first and most important step is to ensure that this disease does not enter pig houses. You can achieve this by maintaining cleanliness in the houses and the surrounding environment.
Always monitor the condition of your livestock. If you notice any signs of illness, call a veterinarian immediately.
Isolate sick pigs and make sure they do not roam around outside the pen.
If you suspect a sudden outbreak of any type of disease, ensure that all livestock are not roaming the farm.
Ensure that people and vehicles do not enter the livestock farm indiscriminately as health measures must be taken when entering and leaving the farm or stable.
When new plants are brought to the farm, it is important that they are separated from the old ones for at least 30 days.
