How can chickens reduce their immune response?

Immunization is an indispensable part of the aquaculture industry, which will provide an active immune response for livestock and poultry, thereby reducing the occurrence of major infectious diseases. However, in immunization, there will be an immune response as the subject fears, resulting in immune failure and failure to form immune protection. Youth combined with practice, for chicken friends to answer the three points to reduce the immune response:

Pre-immunization preparation, correct immunization operation, immunization details.

1. Preparation before immunization.

Removing or isolating sub-healthy chicks can cause an immune response to fail in a sub-healthy state. Observe the mental state, defecation, drinking water, and feed consumption of chicks before immunization, and isolate abnormal chicks in advance. At the same time, prophylactic drugs should be stopped 3-4 days before and 3 days after immunization, especially antibiotics.

Anti-stress preparation, about 4 days before and after immunization, add anti-stress drugs such as multivitamin to drinking water, which can alleviate the stress response.

Sanitation and disinfection treatment, disinfection treatment includes environmental sanitation and disinfection of brooding utensils and immunization equipment, friends must develop good habits, how the quality of hygiene directly determines the effect of immunization.

2. Correct immune operation.

In terms of dosage, in the actual immunization, the immunization is usually carried out according to the multiple times of the dosage of the instructions, and the immunization situation is observed.

Immunization method: When drinking water for immunization, pay attention to 2 hours before and after immunization, and you need to stop drinking water. If the drinking utensils cannot be made of metal, it should be ensured that there are no disinfectants and metal ions in the water, and a small amount of skimmed milk powder should be added to the cold boiled water as a protective agent under normal circumstances.

When injecting and inoculation, it is necessary to hold and stabilize the chicks, and the youth generally chooses the neck subcutaneously at the inoculation site, and the thumb and index finger pinch the neck**, and pierce the gap formed by the pinching.

3. Immunity details.

Light: Generally, thermal insulation lamps will be set up in the brooding room, and chicks will be more active under the care of thermal insulation lamps; It is possible to temporarily turn off the thermal light while immunized.

The choice of vaccination needle, the injection should choose a smaller needle, so as to reduce the outflow of vaccine after immunization is removed.

Improve the environment in which chickens are raised, such as ventilating them more, allowing them to participate in outdoor activities, and not always keeping them together. In addition, chickens must be vaccinated when they are still young.

First of all, the entire site should be disinfected, and then refined management should be carried out. In this way, the chickens can improve their immunity.

If you want to reduce the immune response, you should first vaccinate your chickens every three months. That way, they won't have an immune response.

Some Chinese herbs have the effect of enhancing the body's immunity and can improve the immunity of the flock. For example, Astragalus polysaccharide powder (Shi Kening), Astragalus is a traditional Chinese medicine that replenishes qi, and has the effects of invigorating qi, replenishing deficiency and raising yang. A large number of studies have shown that the main component of Astragalus membranaceus polysaccharides has obvious immune-enhancing functions, and Astragalus polysaccharides have a variety of pharmacological effects such as immunomodulatory, anti-tumor, and antiviral, the most important of which is immune-enhancing effect.

Shi Konin - astragalus polysaccharide soluble powder.

Not all astragalus polysaccharides are called schkorin.

Features: 1.Boosts immunity:

It is mainly achieved through three aspects: Schkorinin can effectively enhance non-specific immune function and has a dual promotion effect on cellular immunity and humoral immunity. Schkorin can enhance cell stability, and the permeability of the cell membrane will not increase significantly under stress, so as to improve the body's resistance.

Schkonine can promote the proliferation and activity of natural killer cells (NK cells) and improve immunity.

2.Enhance the thickness of the intestinal wall, the thickness of the mucosa and the length of the villi of the small intestine, enhance the absorption function of the small intestine, promote the growth and development of the body, and improve the utilization rate of feed.

3.High drug content: vacuum negative pressure ultrasonic wall breaking technology is used to break the plant cell wall, thermal reflux low-temperature critical extraction and vacuum low-temperature concentration technology to ensure that the concentration and biological activity of the extract are not destroyed, and finally ultrafiltration and macroporous resin adsorption technology are used to purify and concentrate again, and finally prepare high-purity and high-concentration products (crude drug ratio is above).
