Prevention of chicken disease should pay attention to the route of transmission

In the transmission route of chicken disease, many factors and factors play a great role in it. Infectious factors can be separated from sick chickens through blood-sucking insects in the feces of sick chickens, or in the infected organ, parts and excreta.
Drinking water transmission. If care is not taken to prevent contamination, infectious excrement or parasite eggs that fall into the sink can easily be pecked by chickens.
Bedding contagion. Normally, litter provides a ready hiding place for bacteria and parasite eggs, some of which survive in this environment for a long time. Because chickens have the habit of constantly pecking at particles from the ground, there is always a chance for them to peck at infectious substances.
through vector insects. Vector insects are those that do not infect themselves, but are capable of transmitting infectious agents from one chicken or animal to another, such as flies, mosquitoes, ticks and fleas. Clinically, fowlpox spreads more through vector insects.
Airborne. Air can spread the source of infection from one farm to another. Diseases such as Newcastle disease, infectious bronchitis and laryngotracheitis can be easily spread through the air.
Apparatus spread. The transmission of infectious diseases, such as pullorum, to newly hatched healthy chicks through contaminated incubators and poultry house contaminated incubators or brooders.
Contact spread. Cohabitation of infected and susceptible chickens provides a ready route for the spread of the disease, not only through physical contact, but also as a result of chicken contact with contaminated soil and water. In this case, the sick chicken with obvious symptoms should be isolated or eliminated immediately.
Spread by a carrier. Carriers refer to chickens that have no obvious symptoms of infection but still carry the pathogenic factor of a certain disease, especially those chickens that have been infected and recovered but still carry the pathogenic factor. It is very difficult to find such chickens, such as chicks infected with Marek's disease in the early stage.
Spread by mechanical carriers. Mechanical carriers include all the ways in which pathogenic agents are accidentally carried from one place to another, I .e. people, animals, insects, wind and sand, moving vehicles, feed bags, packing boxes for poultry and contaminated equipment.
It is transmitted by the off-site transport of infected chicks or adult chickens. Some diseases such as pullorum, infectious bronchitis, avian encephalomyelitis and mold body disease, etc., can be passed through these ways without the disease of the chicken farm.
The above is a preliminary analysis of the cause of the disease, it can be seen that the occurrence and spread of chicken disease is complex. In order to maintain a healthy and profitable chicken flock, chicken farmers should not only do a good job in the prevention of chicken diseases, but also have an understanding of the causes and transmission channels of chicken diseases, and take corresponding measures according to different situations, so that the chicken flock does not have disease or less disease, so that the efficiency of chicken raising is continuously improved.
