What is the reason for the decline of immunity in chickens

In chicken farms, if the immunity of chickens declines, then various bacterial infections will occur, leading to the disease of chickens, and in order to avoid the disease of chickens, we must first understand the factors that reduce the immunity of chickens, and then do the corresponding preventive measures.

1. Genetic factors

The immunity of parents of different ages, different stages and different breeds is different, affected by genetic factors, some chickens have higher immunity, while some chickens have low immunity. For genetic factors caused by low immunity, this is artificial can not avoid, only in the purchase of chicken seedlings is, choose some regular manufacturers, strong disease resistance chicken seedlings, and for low immunity breeding should be eliminated in time.

2. Poor environmental quality

The air quality of chicken house is also very important to chicken flock. The accumulation of feces in chicken house will produce a large amount of harmful gases such as ammonia and hydrogen sulfide, especially in winter when the ventilation is poor. The ammonia and hydrogen sulfide concentration in chicken house is too high, which will directly stimulate the respiratory mucosa of chicken flock, reduce immunity and easily infect respiratory diseases. Therefore, in winter to do a good job of chicken house cold and warm work is, but also pay attention to the ventilation of the chicken house, clean up the feces in time, improve the intestinal tract of the chicken flock, improve the feed utilization rate, and maintain excellent air quality, which is very important for the immune system.

3. Feed mildew

Feed mildew is common in breeding, and vomiting, fumagillin and zearalenone pollution are the most serious. Mycotoxin poisoning can cause cystitis and enteritis. Feed mildew is the biggest harm to chickens because it causes immunity decline and is easy to infect other diseases. Chickens are extremely sensitive to mycotoxins, which can even cause feed after ingestion. Mildewed corn and animal protein raw materials are the main sources of mycotoxins, so it is recommended to prevent feed mildew in raw materials.

4. Pathogenic infection

Chickens immunosuppressive diseases more common immunosuppressive sexually transmitted diseases are infectious sac disease, infectious anemia factors, salmonella disease, mycoplasma and so on. Chicken infected with these pathogens, will inhibit the production of immunity, different diseases inhibit the production of immune antibodies in different ways, mainly destroy immune cells, inhibit antigens, induce cells to form tumors and so on.

The above is what causes the decline in chicken immunity. I hope it can help you. If you want to know more about it, please pay attention to us.
