Causes and solutions for immunosuppression of breeding poultry

Ⅰ.The main reasons leading to immune suppression in breeding poultry:
1. Diseases that can cause immunosuppression occur in chickens:

Common ones such as: bursitis, avian influenza, avian leukemia, Marek's disease in chickens, etc., can severely invade the body's immune system and cause immunosuppressive diseases.

2. Drug side effects:
Such as furazolidone (furazolidone), sulfa drugs, chloramphenicol, thiamphenicol, penicillin, chlortetracycline, etc. These drugs often cause anemia and immunity because they can inhibit bone marrow hematopoietic function and inhibit bone marrow synthesis of immune globulin. inhibition.
3. Stress response:
In daily work, behaviors such as vaccination, overcooling, overheating, catching, swarming, beak cutting, refueling, etc. can cause fear or anxiety in the body, which can lead to metabolic disorders and immunosuppression.
4. Improper medication or incorrect immunization:
Drug poisoning can cause inflammatory reactions or hemorrhagic reactions in immune organs, resulting in suppressed or inefficient expression of immunity; different vaccination methods of vaccines will produce different immune effects, and improper vaccination methods can also cause immunosuppression.
5. Moldy feed and lack of trace elements:
Moldy feed contains a variety of molds and mycotoxins, which can easily cause immunosuppression and can easily cause long-term disease; the balance of various mineral elements in the diet is an important part of maintaining the body's normal physiological metabolism and enhancing physical fitness. The lack of trace elements can easily cause immunosuppression.
Ⅱ.Countermeasures:
1. Use high-quality and efficient vaccines:
Strictly implement vaccination procedures and formulate scientific breeding poultry prevention and immunization procedures.
2. Choose reliable medicines:
In the process of preventing and treating epidemic diseases, try to choose some reliable quality and reputable drugs from manufacturers to avoid immunosuppression due to drug side effects.
3. Choose immune microecological products that relieve immunosuppression:
Such as: Duke, the product is composed of immune-enhancing Lactobacillus plantarum, Pediococcus lactis and their metabolites, dendritic cell immune peptides, glucose, etc. The total number of viable bacteria ≥8.0×10^11CFU/bottle.

① Promote the differentiation and maturation of dendritic cells.
Dendritic cells are the most powerful full-time antigen-presenting cells in the body. They can efficiently ingest, process, and present antigens such as viruses and bacteria. They are at the center of initiating, regulating, and maintaining immune responses.
② Produce a variety of cytokines.
Can promote the intestinal secretion and production of interferon-α (α-IFN), interferon-γ (γ-IFN), interleukin-2 (IL-2), interleukin-10 (IL-10), tumor necrosis factor (TNF) -α), etc., fully activate animal antigen-presenting cells, phagocytes, natural killer cells, T, B lymphocytes and other immune cells, and have good immune effects against a variety of viruses and pathogens, thereby enhancing the non-specific immunity of breeders .
③It can effectively relieve the immunosuppression that is common in animals.
Bora Lilac can induce mature dendritic cells to activate the systemic immune response and effectively increase the potency of the vaccine.
