Is a bleeding pig nose a symptom of African swine fever?
With the outbreak of African swine fever, many people panic at the mere mention of swine fever. Farmers avoid swine fever like the plague. At the slightest symptom in a pig, they worry whether it is swine fever. So, is a bleeding pig nose African swine fever?
I. Is a bleeding pig nose African swine fever?
A bleeding pig nose is not necessarily African swine fever. There are many other causes of a bleeding pig nose, such as weather conditions, feeding methods, nutritional problems and many other factors. It should be judged according to the actual symptoms of the nosebleed.
II. Causes of a bleeding pig nose
1. Weather: In winter, the weather is cold and the air is dry, and the resilience of the pig's nasal mucosa decreases in the cold, dry air. At the same time, pigs are prone to coughing and asthma in winter. When a pig coughs, the strong airflow passing through the respiratory tract can easily burst the capillaries of the nasal mucosa, causing bleeding.
2. Feeding method: At present, most farmers use dry powder feed to feed pigs. During the process of eating the feed, part of the feed powder attaches to the nasal mucosa with the air, and over time it can form scabs, blocking the respiratory tract and making the pig's nose itch. The pig sneezes out the scabs, and at the same time the nasal mucosa is damaged and the capillaries rupture, which is also a cause of a bleeding pig nose.
3. Nutritional problems: A lack of vitamin K3 in the feed, or improper storage of the feed or the feed being past its shelf life, causes part of the vitamin K3 to decompose and become ineffective, which hinders the synthesis of clotting factors in the liver. After the capillaries in the nasal cavity rupture and bleed, the blood cannot clot immediately, resulting in continuous bleeding.
4. Swine fever: Swine fever can cause a bleeding pig nose, bleeding spots on the skin of the ears, limbs and abdomen, and flushing and cyanosis of the visible mucous membranes, with a mortality rate as high as 100%. Pregnant sows miscarry.
If a pig's nose is bleeding, it should be judged according to the actual situation to determine exactly what is causing it, and then the right treatment should be given so that it can be treated effectively.
