Recently, farmers have reported eyelid tears in their own pigs and asked about the harm of eyelid tears. How to treat? The eyelid tears do reflect some problems in the health of the pigs. Let's learn together.
Generally, the phenomenon of piglet tears in the breeding process is a relatively common disease, especially in the stage of nursery pigs. The mortality rate after the onset is not high, but it has obvious influence on the growth and development of pigs, and the immunity of the body is reduced to reduce the production utilization rate.
First, the factors that cause eyelid tears in the herd
Poisoning
Widely exist in corn, occurrence, aflatoxin in cottonseed cake, etc., which is harmful to the organs of pigs. For example, the management of feed is not good, causing aflatoxin in the feed to invade the kidneys, and there will be flushing, swelling, and secretion of the eyes. Therefore, farmers should remember to mix in the mold remover when using the feed, especially in the breeding of the sow.
2. Infected with pathogenic microorganisms
Infections of pathogenic microorganisms include both viruses and bacteria. When the herd is infected with certain viral diseases, eyelid edema, conjunctival hyperemia, increased secretions or purulent secretions can cause tears. Such as circovirus type 2, swine fever virus blue ear virus and the like. Pathogenic bacteria commonly found in bacteria are: pneumococci, Haemophilus influenzae, Staphylococcus aureus, meningococcus and the like. Bacterial invasion of the conjunctiva causes an increase in secretions and secretions that are sticky and purulent and sticky. Conjunctivitis caused by chlamydia is also one of the causes of tear spots.
3. Overuse of antibiotics
Due to the high incidence of pigs under large-scale farming, most pig farms use large amounts of antibiotics such as antibiotics (such as amoxicillin, oxytetracycline, etc.). Biochemical drugs such as antibiotics mainly cause liver and kidney damage through liver and kidney metabolism. In the theory of traditional Chinese medicine, the liver main eye, liver and kidney damage will be manifested through the eyes, so the abuse of antibiotics will cause an increase in eye secretions, and finally form eyelid tear spots.
4. High fever
Sometimes the disease of the animal body causes the animal to heat up. In the process of fever, it will directly lead to eye fatigue, eye adhesion, and formation of eyelid tears.
Second, prevention measures
In order to prevent the occurrence of tear spots, farmers should try to minimize the use of antibiotics in health care and treatment. In the health care drugs, some Chinese medicine preparations and Astragalus polysaccharides can be used to improve the body environment and improve the body's own immunity. However, if the phenomenon of tear spots occurs, the Astragalus polysaccharides cannot be used. Strengthen feeding management, diligent ventilation, preferably at noon ventilation and time should not be too long. It is not suitable for direct air convection ventilation, diligent cleaning, timely cleaning of pig excrement and pig waste feed residue, disinfection and prevention of disease Occurrence and reduction of the spread of pathogenic microorganisms.
These are all of today's content. If your family's pigs also have symptoms of eyelid tears, then pay attention to their health.
